Adds a v1 audit document and a live-integration +test module. + +- Fixed: streaming responses dropped every tool call. The adapter consumed + the chunk stream via `tokens/1` + `Enum.reduce` for the realtime text + delta, then called `tool_calls/1` on the now-depleted stream and got + nothing. Switched to `ReqLLM.StreamResponse.process_stream/2`, the + documented public API for streaming tool-using agents. +- Fixed: persistent entities (`Cantrip.summon` + `Cantrip.send`) lost + every assistant turn across sends. The terminating branch of entity turn + execution never folded the final assistant message into `state.messages`. + The next send appended a user message to a history that still ended at the + prior user message; the model saw a stack of users with no record of its + own answers and anchored on the first prompt. +- Fixed: folding only preserved one leading `:system` message even though + initial message construction can emit two (identity + capability text). + On fold, the capability text dropped into the foldable body — over long + sessions the entity would silently lose its medium physics instructions. +- Upgraded `req_llm` from `~> 1.9` to `~> 1.12`. v1.12's + `agentjido/req_llm@9d790fd` removes the offending `intersperse` between + Anthropic system content blocks.

It reasons in Elixir, +spawns other entities at runtime, persists its loom across summons, +and can hot-load new code into its own runtime. This document is about running +it responsibly in production. + +The Familiar's default code medium is trusted and operator-local: +LLM-written Elixir runs in the host BEAM with ordinary Elixir affordances. +That makes the prompt's native introspection guidance true: `binding/0`, +`Code.fetch_docs/1`, direct variable reference, `loom.turns`, and public +Cantrip API calls all work in the environment the Familiar inhabits. + +Use the port or Dune sandboxes deliberately for hosted or multi-tenant +audiences. In those modes, LLM-written Elixir is evaluated under a narrower +surface while the parent BEAM owns gates, child cantrip orchestration, loom +grafting, telemetry, provider access, and hot-load policy. + +## The runtime shape + +The parent runtime lives in the application BEAM: cantrip framework, loom +storage, LLM client, gates, telemetry, and Familiar entry point (ACP or +single-shot CLI). By default, the Familiar's code-medium Elixir also runs in +that BEAM. This is the local coding-companion posture: the operator summoned +the entity into their own workspace and can kill the BEAM/process if needed. + +When you choose `sandbox: :port`, the entity's code-medium Elixir instead +runs in a child BEAM reached through an Erlang port. Dune denies ambient +filesystem/system/process authority and boundary crossings are +parent-mediated: gates are RPC handles, `Cantrip.new/1`, `Cantrip.cast/2`, and +`Cantrip.cast_batch/1` are proxied to the parent, and `compile_and_load` is +validated by the parent before compiling inside the child runtime. + +## Safety Posture + +The default controls are structural at the Cantrip runtime boundary: + +- gate validation controls parent-mediated gate calls +- redaction controls observations before they return to the entity/model +- wards bound loop structure and selected runtime policies +- the operator-local host process is the trust boundary for the default + Familiar +- optional `:port`, `:dune`, and deployment isolation modes narrow the + language or process boundary for hosted/multi-tenant use cases + +### 1. Gate root validation + +Filesystem-touching gates (`read_file`, `list_dir`, `search`) accept a +`root` dependency at construction time. Paths the entity passes get +validated against that root before the gate runs. A path that escapes +the root surfaces as an error observation, not a successful read. + +Filesystem gates that require `root` fail closed when `root` is missing. +The old bare `read` gate was removed; use `read_file`. + +This is configured by passing `:root` to `Cantrip.Familiar.new/1`: + +```elixir +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace") +``` + +The Familiar's `list_dir` and `search` gates inherit this root. When the +Familiar constructs child cantrips with `Cantrip.new/1`, parent context +merges the parent's dependencies into the child's gates, so a child given +`gates: ["read_file", "done"]` automatically gets the same root. + +### 2. Credential redaction + +Every gate observation result passes through the internal redaction boundary +before reaching the entity. Pattern-based scrubbing of common +credential shapes: + +- `sk-...` (OpenAI-shaped) +- `sk-ant-...` (Anthropic-shaped) +- `AIza...` (Google) +- `AKIA...` / `ASIA...` (AWS access keys) +- `Bearer ` headers +- Generic env-style `*KEY|SECRET|TOKEN|PASSWORD=...` assignments + +Recursive over strings, lists, and maps so list_dir / search results +stay safe even if a filename or matched line carries a secret. +Non-binary results pass through untouched. + +Defense in depth: even when a path read succeeds (e.g., the entity +reads `.env` because it's inside the configured root), the credential +*bodies* are replaced with `[REDACTED]` before the entity (and the +human watching) ever sees them. + +### 3. Trusted local evaluator + +The Familiar defaults to `%{sandbox: :unrestricted}`. LLM-written Elixir runs +in the host BEAM because the Familiar is an operator-local coding companion: +it is summoned into a workspace by the person responsible for that process. +This default matches the Familiar's prompt and code-medium teaching. Native +Elixir affordances such as `binding/0`, `try/rescue`, `Code.fetch_docs/1`, +ordinary module calls, and direct access to persistent code bindings are +available. + +The runtime still enforces Cantrip-level constraints: gate root validation, +redaction, loop wards, child-depth and child-ward composition, Mix allowlists, +hot-load allowlists, and eval timeouts. These are runtime controls, not a +language sandbox. + +Use this default only where the operator is willing to let the Familiar run +Elixir in the same trust domain as the host process. If you need LLM-written +Elixir to be unable to call ambient host APIs, choose an alternate evaluator +below. + +### 4. Port isolation and process cleanup + +With `sandbox: :port`, the child BEAM is launched through an Erlang port with +a length-prefixed Erlang-term protocol. The parent sends eval requests; the +child evaluates them through Dune; gate/API/stdout and compile requests cross +the protocol explicitly. On timeout, the parent closes and kills the child OS +process. + +Hot-loading with `evolve: true` also stays inside the child. The parent +validates `compile_and_load` wards (exact module names, path, hash, and signer +policy), then the child compiles and loads the allowed module in its own +runtime, not in the framework VM. + +This sandbox denies ambient `File.*`, `System.*`, `Process.*`, `spawn`, node, +and similar calls, while the port boundary protects the host BEAM. It is the +right starting point for hosted or multi-tenant preassemblies whose prompts +are written for the narrower Dune surface. + +### 5. Child process containment + +The child BEAM process still runs somewhere when you choose a port sandbox. +The port evaluator denies ambient language access to filesystem/system/process +capabilities, but operating-system isolation controls what the child process +could reach if a bug, dependency issue, NIF, VM issue, or explicit +`:port_unrestricted` escape hatch is introduced. + +For production, configure a child runner: + +```elixir +Cantrip.Familiar.new( + llm: llm, + root: "/srv/workspace", + sandbox: :port, + port_runner: ["/usr/local/bin/cantrip-child-sandbox"] +) +``` + +Cantrip prepends that runner before the child `elixir ...` command. The runner +can be a wrapper script around Docker, systemd-nspawn, an OCI runtime, +sandbox-exec, firejail, nsjail, or whatever your platform standardizes on. +Mount only the directories the Familiar should reach, drop OS capabilities the +process doesn't need, set CPU/memory limits, and disable network egress unless +the child genuinely needs it. + +Passing `:port_runner` without an explicit `:sandbox` also selects `:port`, +so existing runner-based deployments keep using the child process boundary. + +If your deployment already runs the entire Cantrip host inside an equally +constrained container, a separate `:port_runner` may be redundant. The +important claim is concrete containment somewhere, not the name of the tool. + +For development: run from an environment you're willing for the entity to +reach. Credential redaction means an accidental `.env` observation is scrubbed +before it reaches the model, but it does not prevent the read itself. If you +need `File.read!("/etc/passwd")` or network egress to be impossible, run the +child or host BEAM inside an OS/container boundary that makes it impossible. + +These two layers compose: redaction handles credentials wherever they +land; deployment isolation handles file paths that shouldn't be +reachable at all. + +### 6. Alternate evaluators + +`Cantrip.Familiar.new/1` accepts `sandbox: :dune`. This routes the code medium +through the in-process Dune evaluator, which restricts language-level +`File.*`, `System.*`, `Process.*`, `spawn`, and `Code.*` calls. + +Cost: Dune also restricts some in-medium operations (`binding/0`, +`try/1`, `Code.ensure_loaded?/1`). The Familiar's prompt teaches +`binding()` introspection and pattern matching with `try/rescue` +fallback as native; under `:dune`, those teachings work less well, +and the entity has to fall back to "just reference variables by name" +and "errors land as observations the next turn sees." + +Use `:dune` deliberately when you want in-process restriction without the child +BEAM boundary. `sandbox: :port_unrestricted` keeps the child process but +evaluates raw Elixir there; it is for trusted experiments and process cleanup +tests. `sandbox: :unrestricted` is the default trusted host-BEAM evaluator for +operator-local Familiars. + +## Loom backends + +The loom is the durable record of every turn the Familiar and its +children have ever taken. Three backends: + +| Backend | Strengths | Use case | +| --- | --- | --- | +| **Mnesia** (default for workspace-scoped Familiars) | BEAM-native, transactional, queryable, distributable across nodes | Production | +| **JSONL** | Portable, exportable, human-readable | Development, sharing traces, off-BEAM consumers | +| **In-memory** (default with no `root`) | Fast, ephemeral | Tests, scratch sessions | + +Selection by `Cantrip.Familiar.new/1` options: + +```elixir +# Default: workspace-scoped Mnesia table derived from root +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace") + +# Explicit JSONL for exportable traces +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace", + loom_path: "/var/log/cantrip/my_familiar.jsonl") + +# Explicit Mnesia table +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace", + loom_storage: {:mnesia, [table: :my_table]}) + +# Ephemeral +Cantrip.Familiar.new(llm: llm) +``` + +Mnesia's table name is derived from the workspace root (a sanitized +basename plus a short hash of the full path), so multiple summons +against the same workspace converge on the same loom; distinct +workspaces don't collide. + +Workspace-scoped Mnesia uses a named BEAM node. The launcher persists that +node's distributed-Erlang cookie at `.cantrip/cookie` with mode `0600`. Cantrip +generates cookies in the format `cantrip_<48 lowercase hex chars>` so it can +reuse them without creating atoms from arbitrary file content. If the cookie +file exists but does not match that format, startup fails and leaves the file +unchanged. Delete `.cantrip/cookie` explicitly when you want Cantrip to rotate +the workspace cookie. + +## Wards: bounding the loop + +Default wards on the Familiar's circle: + +| Ward | Default | Purpose | +| --- | --- | --- | +| `max_turns` | 20 | Cap on iterations per cast | +| `max_depth` | 3 | Cap on recursive child spawning | +| `code_eval_timeout_ms` | 120,000 (2 min) | Per-turn time bound | +| `allow_compile_modules` | only when `evolve: true` | Hot-reload restricted to exact module names | + +Tune per deployment. Long-running workflows may want higher +`max_turns`; cost-sensitive deployments may want lower +`code_eval_timeout_ms`. The Familiar's prompt does not need to know +these numbers — the wards are enforced by the circle, not by the +entity. + +## Hot reload (self-modification) + +`compile_and_load` is opt-in for the Familiar. Pass `evolve: true` to include +the gate and scope it to the exact modules listed in `allow_compile_modules`. +The built-in Familiar configuration allows the `Cantrip.Hot.*` modules it +declares for evolution; arbitrary namespace allowlists are no longer accepted. +The entity can hot-load those allowed modules into its current evaluator +session. It cannot redefine `Cantrip.Familiar`, the gate runtime, or any other +framework module — the parent rejects framework module names before compiling. + +This is the entity's evolutionary surface. Combined with the BEAM's +hot-code-loading semantics (old version stays loaded for active processes; +new version takes over for new calls), the Familiar can try a scoped change. +When running under a port sandbox, port-session restart on timeout/crash also +discards the child runtime session. + +Deployments that don't want hot reload should leave `evolve` unset. Custom +circles built with `Cantrip.new/1` can still opt into `compile_and_load` +explicitly when that is the right boundary. + +## Recommended production posture + +```elixir +Cantrip.Familiar.new( + llm: llm, + root: workspace_root, + # Mnesia loom inferred from root; transactional, queryable + max_turns: 50, + # Heavier wards for long-running production work + child_llm: cheaper_llm_for_simple_subtasks +) +``` + +Plus: + +- Container-isolated BEAM process; only `workspace_root` and the + cantrip framework code mounted in. +- Credential redaction is always on; nothing to configure. +- `:telemetry` event handlers wired to your observability stack + (every gate call, every turn, every fold emits events). +- Mnesia's persistence directory mounted to durable storage. + +Optional: + +- `sandbox: :port` plus `port_runner: [...]` for hosted or multi-tenant + deployments that need a child process boundary. +- `sandbox: :dune` if the BEAM is shared with untrusted tenants and the + prompt/capability text is written for Dune's narrower surface. +- `evolve: true` only when hot-load self-extension is part of the deployment. +- Mnesia replication across cluster nodes if you're running + distributed. + +## What the framework does NOT provide + +Honest list: + +- **Network isolation.** Outbound network calls available to the child or + parent process go wherever your DNS resolves.

Put it in a REPL — now it writes code, sees what happened, writes more code. Variables persist. Errors come back as observations. The environment pushes back with truth, and the model adjusts. That's a cantrip: a self-modifying loop of language. +Putting language in a loop can make it come alive. You say words, the words +change the room, the room changes you, you say different words.

The circle has a **medium** — the substrate the entity works *in*, like a code sandbox or a bash shell — plus **gates** (functions that cross the boundary, like reading files or delegating to child entities) and **wards** (hard constraints like turn limits). The action space follows a formula: **A = (M + G) − W**. Everything the medium and gates allow, minus whatever the wards restrict. +## Workflows + +The same package primitives cover several distinct shapes: + +- **Workspace cantrip** — give an entity a medium, gates, wards, and a loom so + it can work in a real environment with explicit controls. +- **Persistent entity** — summon the cantrip into an OTP process when related + prompts should share process-owned state. +- **Child cantrip composition** — fan out work to specialized children and + graft their results and looms back into the parent run. +- **Familiar coordinator** — use the packaged codebase-facing entity when you + want workspace gates, code-medium reasoning, durable memory, and delegation + assembled for you. +- **Distributed Familiar** — place child cantrips on named BEAM nodes and + replicate Mnesia loom tables across the cluster. +- **Familiar evals** — run curated prompt scenarios across multiple seeds, + score them with rubric criteria, and persist transcripts for review. +- **Protocol surface** — expose the same runtime through library calls, Mix + tasks, streaming events, or stdio ACP. -When you `cast`, the entity loops. It writes code, the sandbox runs it, and the results come back — not as raw data in the prompt, but as a summary. To use the data, the entity stores it in a variable and operates on it with more code. It catches errors and adjusts. Turn by turn, it builds up an analysis the way you would in a Jupyter notebook — except the notebook writes itself. Because code is compositional, the entity composes actions nobody enumerated in advance. That's the core insight: a model in a REPL can do things a model with pre-built tools cannot. +### Build a Workspace Cantrip -Gates let the entity reach outside the circle — read a file, spawn a child entity, fetch a URL. In a code medium, gates are just functions the entity calls in its code, freely composed in loops and conditionals. Wards are structural, not advisory: if the turn limit is 30, turn 31 doesn't happen. Every turn is recorded in the **loom** — an append-only tree. Threads that end with `done` are *terminated*; threads cut short by wards are *truncated*. The distinction matters for training data. +A code-medium cantrip that inspects a workspace through scoped filesystem +gates and leaves a JSONL loom behind. The entity thinks in Elixir, uses +`list_dir`, `search`, and `read_file` as host functions, and records every +turn: -The pattern is defined by a [spec](./SPEC.md) and a [behavioral test suite](./tests.yaml).

Children are constructed through the public package API: + +```elixir +data = read_file.(path: "metrics.txt") +done.("Read #{byte_size(data)} bytes") ``` -## What's in the spellbook +Plain code-medium cantrips use the safe port boundary by default: LLM-written +Elixir is evaluated by Dune inside a child BEAM process, while gates, child +cantrip API calls, stdio, and hot-loading are resolved through explicit +parent/child protocol messages. Use `%{sandbox: :port}` when you want that +default boundary to be explicit in a circle. The Familiar defaults to +`sandbox: :unrestricted` for trusted operator-local coding work so native +Elixir affordances such as `binding/0` and `Code.fetch_docs/1` match what its +prompt teaches. Use `sandbox: :port_unrestricted` only when you explicitly +want raw Elixir in the child process, `sandbox: :dune` when you want +in-process language restriction with a deliberately smaller binding surface +(see [docs/port-isolated-runtime.md](./docs/port-isolated-runtime.md) for the +divergence — entity prompts need to match the variant in use), or `sandbox: +:unrestricted` for trusted local development in the host BEAM. +Child-origin atoms outside Cantrip's wire vocabulary cross the port boundary +as strings, which keeps hot-loaded child code from forcing new atoms into the +parent BEAM. + +**Bash.** The entity writes shell commands. Each command runs in a fresh +OS-sandboxed subprocess from the configured cwd. Shell state does not persist. +Filesystem writes are denied except under `%{bash_writable_paths: [...]}`, and +network is off unless `%{bash_network: :on}` is declared. Declared gates are +projected as commands at the front of `PATH`: `read_file README.md`, +`list_dir .`, `search pattern lib`, `mix test`, and `cantrip_done "answer"` +for the `done` gate. `SUBMIT:` output still works for shell-only answers. The +Bash sandbox is release-tested against representative local shell workloads +(`git`, `make`, `jq`, redirects through `/dev/null`, and common +`find`/`sed`/`grep` pipelines); that workload suite is the support contract +for expanding the adapter configuration over time.

To make it do things, you close the loop: take the model's output, run it in an environment, and let it observe the effects. The environment pushes back: code runs or crashes, files exist or don't, tests pass or fail. Turn by turn, the model accumulates experience. It starts doing things its designers never enumerated, because the action space is a programming language and programming languages are compositional. - -That's the shape: call and response. You draw a circle, you speak into it, something answers. Each turn through the loop brings the model closer to the task or reveals why the task is harder than it looked. - -This spellbook gives names to the parts of that loop. Three are fundamental: the **LLM** (the model), the **identity** (the immutable configuration that shapes it), and the **circle** (the environment it acts in). The LLM thinks. The identity tells it who it is. The circle is where it acts. Everything else is what happens when you put those three together and let the loop run. - -The circle has an interior and a boundary. The interior is the **medium** — the substrate the entity works *in*. Think of it like an artist's medium: oil, marble, code. The boundary is crossed by **gates** — host functions that reach the outside world. **Wards** constrain what is possible — turn limits, resource caps, scope restrictions. The entity's action space is the medium's primitives, plus the registered gates, minus whatever the wards restrict: A = M ∪ G − W. - -The **loom** records every turn. The entity is transient; the loom is durable. It is simultaneously the debugging trace, the training data, and the substrate for replay, forking, and persistence across casts. - -The same pattern works at every scale. The simplest cantrip is an LLM in a loop with one gate (`done`) and a turn limit. The most complex is a tree of entities with recursive composition, a loom feeding comparative reinforcement learning, and circles nested inside circles. Same vocabulary, different configuration. Any implementation that passes the accompanying test suite (`tests.yaml`) is a valid cantrip. Terms are defined in context as they appear; the Glossary at the end is for quick reference. - ---- - -## Chapter 1: The Loop - -Everything in this document — every term, every rule, every architectural decision — exists to give structure to one idea: a model acting in a loop with an environment. The loop is the foundation. Start here. - -### 1.1 The turn - -Each cycle through the loop is called a **turn**. A turn has two halves. - -First, the **entity** — the running instance of the model inside the loop — produces an **utterance**: text that may contain executable code or structured calls to the environment. Then the **circle** — the environment — executes what the entity wrote and produces an **observation**: a single composite object containing an ordered list of results, one entry per gate call, plus sandbox output if applicable. The observation feeds into the next turn as one unit. State accumulates. - -``` -LOOP-1: The loop MUST alternate between entity utterances and circle observations. Two consecutive entity utterances without an intervening observation MUST NOT occur. -``` - -This strict alternation is what makes the loop a loop and not a monologue. The entity acts, the world responds, the entity acts again with the world's response in hand. - -The script that defines the loop — which model, which configuration, which environment — is called a **cantrip**. The goal the entity is pursuing is called an **intent**. Both get their own treatment later. For now, what matters is the cycle: act, observe, repeat. - -Closing the loop is what transforms a predictor into an actor. When outputs influence subsequent inputs, the system transitions from passive prediction to world-shaping action. The model's completions change the environment, the changed environment changes the next prompt, and the model adjusts. The loop is the mechanism by which a generative model becomes something that acts. - -### 1.2 What the entity perceives - -On every turn, the entity needs to know two things: what it's supposed to do, and what has happened so far. - -The **identity** — the immutable configuration that shapes the model's behavior — and the **intent** — the goal — are always present. Think of them as the entity's fixed orientation: who it is, and what it's after. Those never change. - -Everything beyond that is mediated by the circle. In the simplest design, the circle presents the full history of prior turns as a growing message list. In a code circle, the entity can access state through code instead: reading variables, querying data structures, inspecting files that persist between turns. Both are valid. What the entity sees is the circle's decision. - -``` -LOOP-5: The entity MUST receive the identity and the intent on every turn. How prior turns are presented — as a message history, as program state, or as a combination — is determined by the circle's design. The circle mediates what the entity perceives. -``` - -### 1.3 Termination and truncation - -Every loop ends. The question is how, and the answer matters more than you might expect. - -**Terminated** means the entity called the `done` gate — a special exit point that signals "I believe the task is complete." The entity chose to stop. In a code circle, the done gate is projected into the medium as `submit_answer` — the entity calls `submit_answer(result)` in code, and the medium translates this into the done gate on the entity's behalf. - -**Truncated** means a **ward** cut the entity off. A ward is a restriction on the loop — a maximum number of turns, a timeout, a resource limit. The environment chose to stop. The entity was interrupted, not finished. - -``` -LOOP-2: The loop MUST terminate. Every cantrip MUST have the `done` gate (CIRCLE-1) AND at least one truncation condition (a max turns ward). When `require_done_tool` is false, text-only responses also terminate — but the done gate must still be present. -``` - -``` -LOOP-3: When the `done` gate is called, the loop MUST stop after processing that gate. Any remaining gate calls in the same utterance MAY be skipped. -``` - -``` -LOOP-4: When a ward triggers truncation, the loop MUST stop. The implementation SHOULD generate a summary of what was accomplished before the entity was cut off. -``` - -The `require_done_tool` ward controls what happens when the entity produces a text-only response — no code, no gate calls, just words. When false (the default), a text-only response terminates the loop. When true, only an explicit `done` gate call terminates. This is a ward, not an identity property — it constrains the loop, and it composes with OR across parent and child circles (WARD-1). - -``` -LOOP-6: If `require_done_tool` is false (default) and the entity produces a text-only response (no gate calls), the loop MUST treat that as implicit termination. If `require_done_tool` is true, a text-only response MUST NOT terminate the loop — only a `done` gate call terminates. -``` - -``` -LOOP-7: If a `done` gate call is malformed (missing required arguments) or returns an error, the loop MUST NOT mark the turn as terminated. The failure MUST be returned as an observation and normal ward/truncation rules continue to apply. -``` - -Why does the terminated/truncated distinction matter? Because it travels with the data. A terminated thread is a completed episode — training data with a natural endpoint. A truncated thread is an interrupted episode — the entity's final state shouldn't be treated as a conclusion because it wasn't one. Implementations MUST record which occurred. - -### 1.4 The cantrip, the intent, and the entity - -A **cantrip** is the script that produces the loop. It binds an LLM to a circle through an identity — which model, which configuration, which environment. A cantrip is a value, not a running process. You write it once and cast it many times. - -``` -CANTRIP-1: A cantrip MUST contain an LLM, an identity, and a circle. Missing any of these is invalid. -``` - -``` -CANTRIP-2: A cantrip is a value. It MUST be reusable — casting it multiple times on different intents MUST produce independent entities. -``` - -An **intent** is the reason the loop runs — the goal, the task, the thing the entity is trying to achieve. Same cantrip, different intent, different episode. - -``` -INTENT-1: The intent MUST be provided when casting a cantrip. A cantrip cannot be cast without an intent. -``` - -``` -INTENT-2: The intent MUST appear as the first user message in the entity's context, after the system prompt (if any). -``` - -``` -INTENT-3: The intent is immutable for the lifetime of a cast. The entity cannot change its own intent mid-episode. A summoned entity may receive new intents as subsequent casts (ENTITY-5). -``` - -And the **entity** is what appears when you cast a cantrip on an intent and the loop starts running. This is the one that's hard to pin down, because you don't build it — it arises. - -Watch what happens after a few turns. - -The LLM's output on turn twelve doesn't look like its output on turn one. It's referencing variables it created on turn four. It's working around an error it hit on turn seven. It's pursuing a strategy that emerged from something it noticed on turn nine — a pattern in the data that nobody told it to look for. The identity didn't ask for this strategy. The circle didn't suggest it. It appeared in the space between them, born from the accumulation of action and observation. - -This is the entity. Not a thing you built — a thing that arose. The LLM is the same LLM it was before the loop started. The identity hasn't changed. The circle is just an environment, doing what environments do. But the process running through all three of them has developed something like perspective. It has context. It has momentum. It has preferences shaped by what it's tried and what worked. - -You didn't design the entity. You designed the LLM, the identity, and the circle. The entity is what happened when you put them together and let the loop run. - -It will exist for as long as the loop runs. When the loop stops — task complete, budget exhausted, ward triggered — the entity is gone. The LLM remains, unchanged. The circle can be wiped or preserved. But the entity, that particular accumulation of context and strategy and in-context learning, is over. - -Unless you recorded it. But that's a later chapter. - -``` -ENTITY-1: An entity MUST be produced by a cantrip — either by casting (one-shot) or by summoning (persistent). There is no other way to create an entity. -``` - -``` -ENTITY-2: Each entity MUST have a unique ID. Implementations MUST auto-generate a unique entity ID if one is not provided by the caller. -``` - -``` -ENTITY-3: An entity's state MUST grow monotonically within a thread (modulo folding, which is a view transformation, not deletion — see Chapter 6). -``` - -``` -ENTITY-4: When an entity terminates or is truncated, its thread persists in the loom. The entity ceases but its record endures. -``` - -Summoning a cantrip produces a persistent entity. The initial intent starts the loop. When the loop completes — done or truncated — the entity persists. You can provide another intent as a new cast, and the loop resumes with accumulated state. - -Casting is a convenience: summon, run one intent, return the result, discard the entity. Most examples in this document describe casting, because most tasks are one-shot. But the underlying mechanism is always summoning — casting is just summoning with automatic cleanup. - -``` -ENTITY-5: A summoned entity persists after its loop completes. It MAY receive additional intents as new casts. State accumulates across all casts. -``` - -``` -ENTITY-6: Summoning a cantrip multiple times MUST produce independent entities, just as casting does (CANTRIP-2). -``` - -The LLM, the identity, and the circle each have their own chapters. The entity does not, because the entity is not a component you configure. It is what emerges from the components you did configure, once the loop begins. - -### 1.5 The four temporal levels - -Four verbs, four timescales. - -**Query** is the atomic unit. One round-trip to the LLM: messages in, response out. The LLM is stateless, so each query is independent. - -**Turn** is one cycle of the loop. The entity produces an utterance, the circle executes it and returns an observation. A turn is the atom of experience — the smallest unit that has both action and consequence. - -**Cast** is one complete episode. A cantrip is cast on an intent, the loop runs until `done` or a ward triggers, and a result comes back. - -**Summon** creates a persistent entity. The entity survives the completion of its first intent. You can send it additional intents, and the loop resumes with accumulated state. - -These nest cleanly: a summon contains one or more casts, a cast contains one or more turns, a turn contains one or more queries. The nesting is strict — a query never spans turns, a turn never spans casts. - -### 1.6 The RL correspondence - -If you know reinforcement learning, this table shows how the vocabulary maps. If you don't, skip ahead — the spec teaches everything you need without it. The mapping is structural, not formal — these are parallels that help you reason about the system, not mathematical equivalences. - -| RL concept | Cantrip equivalent | Notes | -|-----------|-------------------|-------| -| Policy | LLM + Identity | Frozen weights conditioned by immutable identity | -| Goal specification | Intent | The desire that shapes which actions are good | -| State s | Circle state | Accessed through gates | -| Action a | Code the entity writes | A = M ∪ G − W | -| Observation o | Gate return values + sandbox output | Rich, unstructured | -| Reward r | Implicit or explicit | Gate success/failure; verifier scores; thread ranking | -| Terminated | `done` gate called | Entity chose to stop | -| Truncated | Ward triggered | Environment chose to stop | -| Trajectory | Thread | One root-to-leaf path through the loom | -| Episode | Cast | One cast: intent in, result out | -| Replay buffer | Loom | Tree structure provides comparative RL data | -| Environment reset | New entity, clean circle | Forking is NOT a reset — it continues from prior state | - -The loom's relationship to modern RL methods is developed fully in Chapter 6. - -### 1.7 A complete example - -All the pieces in one place. A file-processing task: count the words in every `.txt` file in a directory and report the total. - -**The cantrip.** LLM: any model that supports tool calling. Identity: "You are a file-processing assistant. Use code to solve tasks efficiently." Circle: a code medium with three gates — `read(path) -> string`, `list_dir(path) -> string[]`, and `done(answer)` — a ward of max 10 turns, and `require_done_tool: true`. Filesystem root: `/data`. - -**The intent.** "Count the total number of words across all .txt files in /data and return the count." - -**Turn 1.** The entity appears, receives identity and intent, and produces: -``` -const files = list_dir("/data"); -``` -Observation: `GateCallRecord { gate_name: "list_dir", arguments: '{"path":"/data"}', result: '["a.txt", "b.txt", "c.txt"]', is_error: false }`. - -**Turn 2.** The entity reads all files: -``` -const a = read("/data/a.txt"); -const b = read("/data/b.txt"); -const c = read("/data/c.txt"); -``` -Three `GateCallRecord` objects, each with `is_error: false` and file contents. - -**Turn 3.** The entity counts and terminates: -``` -const total = [a, b, c] - .map(text => text.split(/\s+/).filter(w => w.length > 0).length) - .reduce((sum, n) => sum + n, 0); -done(total); -``` -Loop terminates with result 1547. - -**The loom.** Three turns, one thread. Each turn records token usage, duration, utterance, and observation. The thread is terminated — a complete episode usable as training data, a debugging trace, or a template for forking. - -**Error as steering.** Same cantrip, but `/data/b.txt` does not exist. Turn 2's observation for `b` returns `is_error: true` with `'ENOENT: no such file or directory'`. Turn 3: the entity sees the error and adapts — counts only `a` and `c`, reports `{ total: 1200, note: "b.txt not found, counted 2 of 3 files" }`. The error did not stop the entity. It steered it. - ---- - -## Chapter 2: The LLM - -The LLM is the model. You send it messages, it sends back a response. That is the entire interface — and the simplicity is the point. - -An LLM does not act on its own. It has no memory between queries, no persistent state. You send it a list of messages and it sends back text, structured gate calls, or both. Then it's done. The next time you query it, you must send everything again. The LLM does not remember that there was a last time. - -``` -LLM-1: An LLM MUST be stateless. Given the same messages and tool definitions, it SHOULD produce similar output (modulo sampling). It MUST NOT maintain internal state between queries. -``` - -This statelessness is the contract, not a limitation. Everything that makes an entity seem to learn across turns comes from the loop feeding the LLM's own prior output back as input. The learning lives in the loop, not in the LLM. - -### 2.1 The LLM contract - -``` -llm.query(messages: Message[], tools?: ToolDefinition[], tool_choice?: ToolChoice, extra?: Record) -> Response -``` - -The inputs: -- `messages` — an ordered list of messages (system, user, assistant, tool). -- `tools` — an optional list of gate definitions, expressed as JSON Schema. -- `tool_choice` — controls whether the LLM must use gates ("required"), may use them ("auto"), or must not ("none"). -- `extra` — optional provider-specific parameters passed through to the underlying API. - -The response contains: -- `content` — text output (may be null if the LLM only made gate calls) -- `tool_calls` — an optional list of gate invocations, each with an ID, gate name, and JSON arguments -- `usage` — token counts (prompt, completion, cached) -- `thinking` — optional reasoning trace (for models that support extended thinking) - -``` -LLM-2: An LLM MUST accept messages up to its provider's context limit. When input exceeds that limit, the LLM SHOULD return a structured error (not silently truncate). In practice, context limit errors may come from the provider API rather than from a pre-check — folding (§6.8) is the primary mechanism for staying within limits. -``` - -``` -LLM-3: An LLM MUST return at least one of `content` or `tool_calls`. A response with neither is invalid. -``` - -``` -LLM-4: Each `tool_call` MUST include a unique ID, the gate name, and arguments as a JSON string. -``` - -``` -LLM-5: If `tool_choice` is "required", the LLM MUST return at least one tool call. If the provider doesn't support forcing tool use, the implementation SHOULD simulate it (e.g., by re-prompting). Implementations MAY rely on provider-native support for forced tool use where available. -``` - -### 2.2 The swap - -Take a working cantrip and replace the LLM. Keep everything else — the circle, the identity, the gates, the wards, the intent. The entity that appears behaves differently. It reasons differently, makes different mistakes, pursues different strategies. The LLM is the one component you swap to change how the entity thinks without changing what it can do or where it acts. - -### 2.3 Provider implementations - -In practice, LLMs come from different providers with different APIs. The spec requires support for at least: **Anthropic** (Claude), **OpenAI** (GPT), **Google** (Gemini), **OpenRouter** (proxy), and **Local** (LM Studio,vLLM, any OpenAI-compatible endpoint). - -``` -LLM-6: Provider implementations MUST normalize responses to the common LLM contract. Provider-specific fields MAY be preserved as metadata but MUST NOT be required by consumers. -``` - -``` -LLM-7: In providers that require tool-call/result pairing, implementations MUST preserve call-result linkage exactly (including tool call IDs and ordering). Adapters MUST NOT emit tool-result messages unless the preceding assistant message contained matching tool calls. -``` - ---- - -## Chapter 3: The Identity - -The LLM is a function. The identity is what you pass to it — or more precisely, the part that stays the same every time you pass it. The identity is everything that shapes the LLM's behavior before any intent arrives. - -``` -IDENTITY-1: The identity MUST be set at cantrip construction time and MUST NOT change afterward. -``` - -### 3.1 What the identity contains - -The identity is the union of two things: - -1. **System prompt** — persona, behavioral directives, domain knowledge. -2. **Hyperparameters** — temperature, top_p, max_tokens, stop sequences, sampling configuration. - -The LLM needs to know what gates are available — but that knowledge comes from the circle, not the identity. The circle registers gates, executes them, and presents them to the LLM as tool definitions at query time. The identity stays small and separable: the same identity can work in different circles with different gate sets. - -``` -IDENTITY-3: Gate definitions are the circle's responsibility. The circle MUST present its registered gates to the LLM as tool definitions at query time. The identity carries rendered gate definitions produced by the circle for transport convenience, but the circle remains the authority for what gates exist. The circle — not the identity — registers, executes, and presents gates. -``` - -### 3.2 Immutability and identity - -The identity is fixed. You can create a new cantrip with a different identity, but you can't mutate an existing one. This gives you clean axes of variation: - -Same LLM + different identity = different entity behavior. Same LLM + same identity + different circle = different capabilities. Same everything + different intent = different episode. - -``` -IDENTITY-2: If a system prompt is provided, it MUST be the first message in every context sent to the LLM. It MUST be present in every query, unchanged. -``` - -### 3.3 What the identity is not - -Context belongs in the environment, not in the prompt. Dynamic context — retrieved documents, injected state, programmatic insertions that change per turn — is circle state, accessed through gates. A cantrip that processes a thousand documents places them in the circle as data the entity can read, query, and navigate through code. The identity tells the entity who it is. The circle contains what it works with. The identity doesn't grow. The circle does. - -### 3.4 The identity in the loom - -``` -IDENTITY-4: The identity MUST be stored in the loom as the root context. Every thread starts from the same identity. -``` - -``` -IDENTITY-5: Folding (context compression) MUST NOT alter the identity. The entity always retains its full identity. Only the trajectory (turns) may be folded. -``` - ---- - -## Chapter 4: The Circle - -The LLM thinks. The identity shapes. The circle is where the entity acts. - -### 4.1 What a circle is - -A circle is anything that receives the entity's output and returns an observation. Every circle has an interior and a boundary. The interior is the **medium** — the substrate the entity works *in*. The boundary is crossed by **gates** and constrained by **wards**. - -The medium matters more than it might seem. It determines what the entity is doing when it acts — not what it calls out to, but what it thinks *in*. Conversation, code, a shell, a browser, a proof assistant. The medium is the inside of the circle. - -Circles exist on a spectrum of expressiveness determined by their medium. - -A **conversation circle** uses natural language as its medium. The simplest case is a human circle — you are the environment, the entity speaks, you respond. But conversation is also the medium when two models talk to each other, or when a model talks to a human through a chat interface. The action space is whatever the model can say: A is just language. This is already a complete medium. Not every task needs code. - -A **tool-calling circle** adds gates to conversation. The entity invokes JSON functions — `read`, `fetch`, `search` — and receives structured results. The medium is still conversation, but the boundary now has crossing points. The action space is the gate set: A = G − W. - -A **code circle** gives the entity a full execution context — a sandbox where it writes and runs arbitrary programs. The medium is code. Variables persist between turns. The action space is the full formula: A = M ∪ G − W. The entity can combine primitives and gates in ways nobody enumerated in advance — loops that call gates conditionally, variables that store results for later turns, data pipelines composed on the fly. This compositionality is what makes code circles the most expressive case — but expressiveness is not the only thing that matters. - -The code medium is not limited to JavaScript sandboxes. Any REPL-like environment can serve: a bash shell, a browser session via CDP, a Frida session. What makes something a medium is that the entity writes instructions in it and the medium executes them. - -``` -MEDIUM-1: A circle MUST have exactly one medium. If no medium is specified, the default is conversation. Public configuration SHOULD use `medium` rather than implementation-specific names (`circle_type`, `backend`, `sandbox_backend`). -``` - -``` -MEDIUM-2: A conformant medium MUST provide four things: gate presentation (presenting gates to the LLM as tool definitions appropriate to the medium), action execution, observation return, and sandbox isolation. The medium enforces the circle's boundary. -``` - -The spec requires sandbox isolation but does not prescribe the technology. QuickJS, Deno, Docker, WASM, restricted Python, Firecracker microVMs — any isolation mechanism that enforces the circle's boundary is valid. - -``` -MEDIUM-3: In a code medium, sandbox state MUST persist across turns within the same entity. A variable set in turn 3 MUST be readable in turn 4. -``` - -``` -MEDIUM-4: Mediums MAY define medium-specific ward types (see WARD-2). -``` - -When a circle has a medium, the medium handles termination internally — the entity calls `submit_answer` in code, and the medium translates this into the done gate mechanism. - -### 4.2 What the entity can do - -The entity's capabilities in a code circle are described by a formula: - -``` -A = M ∪ G − W -``` - -**M** is the medium — builtins, math, strings, control flow, data structures. **G** is the set of registered gates — host functions that cross the boundary into the outside world. **W** is the set of wards — restrictions that constrain the action space. - -When the medium is a programming language, the action space is compositional. The entity can combine primitives and gates in ways nobody enumerated in advance. This compositionality is what separates a code circle from a tool-calling interface. - -``` -CIRCLE-1: A circle MUST provide at least the `done` gate. -``` - -``` -CIRCLE-8: The `done` gate MUST accept at least one argument: the answer/result. When `done` is called, the loop terminates with that result. -``` - -### 4.3 Gates - -Gates are the crossing points through the circle's boundary: how effects reach the outside world, and how outside information reaches the entity. - -Common gates: `done(answer)`, `call_entity(intent, config?)`, `call_entity_batch(intents)`, `read(path)`, `write(path, content)`, `fetch(url)`, `goto(url)` / `click(selector)`. - -Empirical evidence suggests that fewer, well-designed gates often outperform larger gate sets. When the medium is expressive, the entity can compose complex behaviors from a small number of gates. - -Each gate closes over environment state configured at construction time (§7.3). A `read` gate knows its filesystem root. A `fetch` gate carries timeout configuration. The entity calls `read("data.json")` without knowing where the root is. The gate knows. - -``` -CIRCLE-10: Gate dependencies (injected resources) MUST be configured at circle construction time, not at gate invocation time. -``` - -``` -CIRCLE-3: Gate execution MUST be synchronous from the entity's perspective — the entity sends a gate call, the circle executes it, the observation returns before the next turn begins. -``` - -``` -CIRCLE-4: Gate results MUST be returned as observations in the context. The entity MUST be able to see what its gate calls returned. -``` - -``` -CIRCLE-5: If a gate call fails (throws an error), the error MUST be returned as an observation, not swallowed. The entity MUST see its failures. -``` - -Errors are observations. They carry information the entity needs to learn from. Swallowing errors silently cripples the entity — if a file does not exist, the entity needs to see the error so it can try a different path. - -The canonical gate result shape: - -``` -GateCallRecord { - gate_name: string // which gate was invoked - arguments: string // JSON-encoded arguments - result: string // gate output (return value or error message) - is_error: boolean // true if the gate call failed -} -``` - -The observation per turn is an ordered list of `GateCallRecord` objects. A code circle's observation additionally includes sandbox output (stdout, return value, errors). The minimum contract: an observation MUST contain an ordered list of GateCallRecords for every gate invoked during the turn, each with `gate_name`, `arguments`, `result`, and `is_error`. Mediums MAY add additional fields. - -``` -CIRCLE-7: If multiple gate calls appear in a single utterance, the circle MUST execute them in order and return each result as an entry within that turn's single composite observation. The observation is one object per turn (preserving LOOP-1's strict alternation), with an ordered list of per-gate results inside it. Implementations MAY execute independent gate calls in parallel. -``` - -### 4.4 Wards - -Gates open the circle outward. Wards close it back in. They constrain the action space — not permissions granted from nothing, but restrictions carved from the full surface. - -A ward that restricts a gate's reach: "read only from /data." A ward that constrains the medium: "no eval." A ward that caps turns: "max 200 turns." A ward that limits resources: "max 1M tokens." A ward that controls termination: `require_done_tool`. Gate inclusion is a construction concern, not a ward — if you don't want a gate, don't register it. - -``` -CIRCLE-2: A circle MUST have at least one ward that guarantees termination (max turns, timeout, or similar). A cantrip that can run forever is invalid. -``` - -``` -CIRCLE-6: Wards MUST be enforced by the circle, not by the entity. The entity cannot bypass a ward. Wards are environmental constraints. -``` - -A ward is not an instruction the entity might choose to ignore. It is a structural property of the environment. If `fetch` is not registered, the entity cannot make HTTP requests no matter what it writes. If the turn limit is 200, turn 201 does not happen. The entity cannot reason its way around a ward because the ward operates outside the entity's control. - -Start with the fullest possible action space. Then ward off what is dangerous. You do not build up from nothing — you carve down from everything. - -When circles compose — a parent spawning a child via `call_entity` — their wards compose conservatively: the child can never be *less* restricted than its parent. `require_done_tool` uses logical OR: if any ward requires it, it is required. - -``` -WARD-1: When circles compose, numeric wards (max turns, max tokens, max depth) MUST take the `min()` of parent and child values. Boolean wards (`require_done_tool`) MUST take logical `OR` — if either ward requires it, it is required. A child circle's wards can only tighten, never loosen, the parent's constraints. -``` - -``` -WARD-2: Mediums MAY define additional ward types specific to their substrate (e.g., `max_eval_ms` for code circles, compile guards for Elixir circles). Medium-specific wards follow the same composition semantics as WARD-1. -``` - -### 4.5 Tool-calling circles - -Not every circle needs a sandbox. When the LLM uses structured tool calls — JSON function invocations rather than code — the medium is conversation and the action space simplifies to A = G − W. Less expressive than a code circle, but simpler to implement and sufficient for many tasks. - -Implementations MUST support tool-calling circles. Implementations SHOULD support code circles. - -### 4.6 Circle-mediated perception - -The circle does more than execute code. It determines what the entity perceives. - -#### The three message layers - -Every query the circle assembles for the LLM has three layers, in this order: - -1. **Identity**. The system prompt and hyperparameters — who the entity is. Unchanged from construction (IDENTITY-1, IDENTITY-2). - -2. **Capability presentation** (circle-derived). What the LLM can do in this circle — a description of the medium, the registered gates, and their contracts. The circle generates this from its own configuration (CIRCLE-11, IDENTITY-3). It changes when the circle is reconfigured but never during a cast. This separation keeps the identity small and portable — the same identity works in different circles with different gate sets, because the circle presents its own capabilities. - -3. **Intent** (goal). What the entity is pursuing. The first user message, immutable for the cast (INTENT-3). - -Each layer is more specific than the last, and each is owned by a different component: identity owns identity, the circle owns capabilities, the caller owns intent. - -``` -CIRCLE-11: The circle MUST generate a capability presentation for the LLM — a description of the medium, registered gates, and their contracts. This presentation MUST be included in the LLM's context on every query, between the identity and the intent. Gate definitions in the `tools` parameter and capability documentation in the prompt are both valid forms of this presentation. -``` - -#### Gate presentation - -Gate presentation is medium-specific. In a tool-calling circle, each gate appears as a separate tool definition; `tool_choice` defaults to `"auto"`. In a code circle, the LLM sees a single tool — the medium's code execution interface (e.g., `js`); `tool_choice` is `"required"`. Gates are projected into the medium as host functions — the medium decides how they appear. - -``` -// Tool-calling circle: tools = [read, write, fetch, done], tool_choice = "auto" -// Code circle: tools = [js], tool_choice = "required" -// Gates appear as: read(), write(), fetch(), submit_answer() inside the sandbox -``` - -The LLM does not know it is calling gates — it writes code that calls functions. The medium bridges between the LLM's perception and the circle's reality. - -#### The medium viewport principle - -A medium SHOULD present execution results as metadata — size, type, a short preview — rather than raw output. As the prompt fills with raw data, the LLM's ability to attend to relevant information diminishes (context rot). When the medium returns a summary — `[Result: 4823 chars] "first 150 chars..."` — the entity must compose operations to work with the data through code. The viewport forces compositional behavior. - -### 4.7 Circle state - -The circle maintains state between turns in two forms. - -**Sandbox state** — variables, data structures, intermediate results inside the execution context. Private to the entity; dies when the entity terminates. This is MEDIUM-3. - -**External state** — filesystem, database, browser DOM, whatever gates can reach. May be shared across entities or persist beyond an entity's lifetime. - -### 4.8 Security - -Security in the circle model is a question of warding. The canonical threat is the lethal trifecta: a circle that has access to private data, processes untrusted content, and can communicate externally. Any two are manageable. All three create a path for data exfiltration. - -The defense is subtractive. Remove one leg by warding off the relevant gate. A circle that processes untrusted content and reads private data but cannot make network requests is safe against exfiltration. Alternatively, isolate capabilities across separate circles. - -**Prompt injection** is the specific threat that makes careful circle design non-optional. Untrusted content may contain instructions that attempt to override the identity. The entity cannot reliably distinguish between its own instructions and adversarial text embedded in its input. This is a structural property of systems that process natural language: the control channel and the data channel are the same channel. - -Wards cannot prevent the entity from being influenced by its input — they can only prevent the entity's actions from reaching dangerous gates. The defense is circle design: isolate the processing of untrusted content from circles that have access to sensitive data or external communication. - -Wards must be structural, not advisory. The entity has read every attack and every defense in its training data. Containment cannot rely on the entity choosing to respect boundaries — politeness is trained behavior, not a reliable property. Wards are environmental constraints because the entity cannot be trusted to self-limit. - ---- - -## Chapter 5: Composition - -So far, every entity has been alone. Some tasks are too large for one entity, or too naturally decomposable, or too parallelizable. The entity needs to delegate. - -In a code circle, delegation is a function call. The entity writes `call_entity({ intent: "summarize this document" })` and a child entity appears in its own circle, pursues that sub-intent, and returns a result. Composition through gates is composition through code, which means the entity can invent delegation patterns its designers never enumerated. - -### 5.1 The `call_entity` gate - -``` -result = call_entity({ - intent: string, // what the child should pursue - context?: string, // additional context injected into child's circle - gates?: string[], // which gates the child's circle registers - wards?: Ward[], // child-specific wards (composed with parent's via WARD-1) - llm?: string, // which LLM the child uses - identity?: Identity, // the child's identity (system prompt, hyperparameters) - medium?: string // the child's medium (e.g., "code", "conversation") -}) -``` - -The entity proposes the child's configuration. Fields beyond `intent` are optional — defaults are typically inherited from the parent or from construction-time configuration. Behind the scenes, a **spawn function** (`SpawnFn`) receives the proposal and handles circle construction, ward composition, depth decrement, and loom sharing. The spawn function validates and may modify the proposal — enforcing ward tightening (WARD-1) or rejecting gate sets that violate security policy. - -The child entity gets its own circle, its own context, its own turn sequence. It does not inherit the parent's conversation history — it starts fresh, with only the sub-intent and whatever data the parent passes through `context`. - -``` -COMP-4: A child entity MUST have its own independent context (message history). The child does not inherit the parent's conversation history. -``` - -``` -COMP-1: A child entity's circle is independently constructed. The parent MAY constrain the child via ward composition, but the child's gate set, medium, and LLM are not required to be derived from the parent. -``` - -``` -COMP-7: The child's LLM MAY differ from the parent's LLM. The child's identity MAY differ. The child's circle MAY differ — including different gates, a different medium, or different wards. Ward composition (WARD-1) still applies to any wards the parent imposes. -``` - -If the caller does not specify a child identity, the child gets a generic prompt oriented toward task completion — not the parent's identity. The child is a worker, not a clone. - -``` -COMP-10: If no identity is provided for a child entity, the implementation MUST supply a generic child identity (e.g., "You are a child entity. Pursue the intent and return the result."). The child MUST NOT inherit the parent's system prompt by default. -``` - -``` -COMP-11: The spawn function MUST strip `call_entity` and `call_entity_batch` from the child's gate set when the child's composed `max_depth` is 0 (see COMP-6). The child's circle is constructed without delegation gates — the child cannot attempt to delegate. -``` - -The parent blocks while the child runs — the same synchronous contract as any other gate (CIRCLE-3). The child entity lives its entire life within the parent's turn. - -``` -COMP-2: `call_entity` MUST block the parent entity until the child completes. The parent receives the child's result as a return value. -``` - -``` -COMP-8: If a child entity fails (throws an error, not `done`), the error MUST be returned to the parent as the gate result. The parent MUST NOT be terminated by a child's failure. -``` - -``` -COMP-9: When a parent entity is terminated or truncated, active child entities SHOULD be truncated with reason `parent_terminated`. Child turns up to the cancellation point are preserved in the loom. The child's truncation is recorded as any other truncation — the loom distinguishes it only by the reason field. -``` - -### 5.2 Batch composition - -`call_entity_batch` spawns multiple children in parallel: - -``` -results = call_entity_batch([ - { intent: "Summarize chunk 1", context: chunk1 }, - { intent: "Summarize chunk 2", context: chunk2 }, - { intent: "Summarize chunk 3", context: chunk3 }, -]) -``` - -Results are returned in request order, not completion order. - -``` -COMP-3: `call_entity_batch` MUST execute children concurrently. Results MUST be returned in request order, not completion order. Implementations SHOULD enforce concurrency limits (default: 8 concurrent children, 50 maximum batch size) to prevent resource exhaustion. -``` - -### 5.3 Composition as code - -The entity calls `call_entity` inside loops, behind conditionals, as part of data pipelines it writes on the fly: - -``` -const chunks = splitIntoChunks(context.documents, 100); -const summaries = call_entity_batch( - chunks.map(chunk => ({ - intent: "Extract key findings", - context: { documents: chunk } - })) -); -done(summaries.join("\n")); -``` - -The number of children is determined at runtime by the data, not at design time by the developer. This is what separates composition-through-code from a static workflow graph. - -### 5.4 Depth limits - -Composition is recursive — a child entity has the `call_entity` gate in its circle, so it can spawn children of its own. Every cantrip has a `max_depth` ward to prevent infinite recursion. - -- Depth 0 means no `call_entity` allowed — the gate is warded off -- Each child's depth limit is the parent's depth minus 1 -- Default depth is 1 (the entity can spawn children, but those children cannot spawn their own) - -``` -COMP-6: When `max_depth` reaches 0, the `call_entity` and `call_entity_batch` gates MUST be removed from the circle (warded off). Attempts to call them MUST fail with a clear error. -``` - -### 5.5 Composition in the loom - -Every child entity's turns are recorded in the same loom as the parent. The child's turns form a subtree rooted at the parent turn that spawned it. - -``` -Parent turn 1 -Parent turn 2 (calls call_entity) -├── Child turn 1 -├── Child turn 2 -└── Child turn 3 (done) -Parent turn 3 (receives child result) -``` - -``` -COMP-5: A child entity's turns MUST be recorded in the loom as a subtree. The child's root turn references the parent turn that spawned it. -``` - ---- - -## Chapter 6: The Loom - -Every chapter so far has produced turns. The loop runs, the entity acts, the circle responds, turn after turn. Then the loop ends and the entity is gone. - -Where did the turns go? - -They went into the loom. Every turn — every utterance, every observation, every gate call — was being recorded as it happened, appended to a growing tree. One path through that tree is a thread. All threads, across all runs of a cantrip, form the loom. The entity is transient; the loom is durable. - -The loom was accumulating from the first turn of Chapter 1. When composition spawned child entities in Chapter 5, their turns went into the same loom. The structure described in every prior chapter — the loop, the observations, the parent-child relationships — is the structure of the loom. - -### 6.1 Turns as nodes - -Each turn is stored as a record: - -``` -Turn { - id: string // unique identifier - parent_id: string? // null for root turns - cantrip_id: string // which cantrip produced this turn - entity_id: string // which entity was acting - role: string // "identity" | "turn" - sequence: number // position within this entity's run (1, 2, 3...) - - utterance: string // what the entity said/wrote - observation: string // what the circle returned - - gate_calls: GateCall[] // structured record of which gates were invoked - - metadata: { - tokens_prompt: number - tokens_completion: number - tokens_cached: number - duration_ms: number - timestamp: ISO8601 - } - - reward: number? // reward signal, if assigned - terminated: boolean // did this turn end with `done`? - truncated: boolean // did a ward cut the entity off here? -} -``` - -``` -LOOM-1: Every turn MUST be recorded in the loom before the next turn begins. Turns are never lost. -``` - -``` -LOOM-2: Each turn MUST have a unique ID and a reference to its parent (null for root turns). -``` - -``` -LOOM-9: Each turn MUST record token usage (prompt, completion, cached) and wall-clock duration. -``` - -### 6.2 Threads - -Turns link to their parents. Follow those links from any leaf to the root and you have a thread — one complete path through the turn tree. Threads are implicit — they emerge from parent references. You store turns with parent pointers; a thread is any root-to-leaf path. - -A thread has exactly one terminal state: **terminated** (`done` called), **truncated** (ward stopped it), or **active** (still running). - -``` -LOOM-7: The loom MUST record whether each terminal turn was terminated (entity called `done`) or truncated (ward stopped the entity). -``` - -This distinction is load-bearing for training. Terminated threads have natural endpoints. Truncated threads do not. - -### 6.3 The loom - -The loom is the tree of all turns produced by a cantrip across all runs. Cast ten intents: ten threads. Fork from turn seven: two threads sharing a prefix. Compose with `call_entity`: child subtrees inside parent threads. - -This is simultaneously the debugging trace, the entity's memory, the training data, and the proof of work. - -### 6.4 Reward and training data - -Each turn is a (context, action, observation) triple. Each thread is a trajectory. The reward slots are already there. - -The loom stores a reward slot on every turn: - -- **Implicit reward** — gate success/failure as a natural per-turn signal. -- **Explicit reward** — a score attached after the fact by a human, a verifier, or a verifier entity. -- **Shaped reward** — intermediate rewards from a scoring function that is part of the circle definition. - -Modern LLM-RL methods — GRPO, RLAIF, best-of-N — learn by comparing multiple trajectories of the same task. Fork from the same turn N times, or cast the same intent N times, and you get N threads to rank. The ranking is the reward signal — no reward model needed. The loom's tree structure provides exactly the trajectory data comparative RL methods need. - -``` -// Same intent, three runs: -// -// Thread A: 12 turns, fixed the bug, clean solution -> rank 1 -// Thread B: 18 turns, fixed the bug, messy refactor -> rank 2 -// Thread C: 25 turns, truncated by ward, bug not fixed -> rank 3 -// -// The ranking IS the reward signal. -``` - -Two metrics apply directly: **pass@k** (at least one of k threads succeeds) and **pass^k** (all k succeed). Both are computable from threads sharing a common intent. - -(Multi-turn credit assignment remains an active research problem. The loom provides the trajectory structure these methods need; credit assignment and reward propagation are the responsibility of whatever training infrastructure consumes it.) - -``` -LOOM-10: The loom MUST support extracting any root-to-leaf path as a thread (trajectory) for export, replay, or training. -``` - -### 6.5 Storage - -Turns are appended as they happen. The loom is append-only. The reference format is JSONL. - -``` -LOOM-3: The loom MUST be append-only. Turns MUST NOT be deleted or modified after creation. Reward annotation is the exception — reward MAY be assigned or updated after creation. -``` - -### 6.6 Forking - -Forking creates a new turn whose parent is an earlier turn in the tree, diverging from the original continuation. - -``` -// Original thread: turns 1 -> 2 -> 3 -> 4 -> 5 -// Fork from turn 3: -// turns 1 -> 2 -> 3 -> 4 -> 5 (original thread) -// \-> 6 -> 7 (forked thread) -``` - -A forked entity starts with the context from root to the fork point. The original thread is untouched. - -``` -LOOM-4: Forking from turn N MUST produce a new entity whose initial context is the path from root to turn N. The original thread MUST be unaffected. -``` - -Implementations MUST declare how sandbox state is captured at fork points. **Snapshot** serializes current state into a portable image. **Replay** re-executes the entity's code from root to the fork point. Both produce the same logical state; they differ in cost and fidelity. Snapshot is fast but may struggle with imperative state that resists serialization. Replay is slow but faithful. The loom MUST record which strategy was used. - -``` -LOOM-13: When using replay-based forking, gate results MUST be hydrated from the loom's recorded observations rather than re-executed. Gates are not called during replay — their recorded results are injected into the sandbox as if the gates had run. This prevents non-idempotent side effects from being duplicated. -``` - -Forking is not an environment reset. The forked entity continues from accumulated state at the fork point. - -### 6.7 Composition in the loom - -When `call_entity` spawns a child, the child's turns form a subtree — the same mechanism as forking. Everything stays in one tree. - -``` -LOOM-8: Child entity turns from `call_entity` SHOULD be stored in the same loom as the parent, with parent references linking them to the spawning turn. Implementations that store child turns in a separate loom MUST still record the parent-child relationship. -``` - -``` -LOOM-12: The loom SHOULD be a single unified tree. When all entities — parent, child, grandchild — record their turns into the same tree, a thread is any root-to-leaf path, and the tree's branching structure encodes the full delegation hierarchy. -``` - -### 6.8 Folding and compaction - -Context grows. Eventually the accumulated context approaches the LLM's window limit. - -**Folding** is the deliberate integration of loom history into circle state. Instead of keeping every prior turn in the message list, the circle takes the substance of earlier turns and encodes it as state the entity can access through code: variables, data structures, summaries in the sandbox. The full turns remain in the loom. The entity's working context shrinks because the knowledge now lives in the environment — context belongs in the environment, not in the prompt (§3.3). - -``` -LOOM-5: Folding MUST NOT destroy history. The full turns MUST remain accessible. Folding produces a view, not a mutation. -``` - -``` -LOOM-6: Folding MUST NOT compress the identity or the circle's gate definitions. The system prompt, hyperparameters, and gate definitions MUST always be present in the entity's context. -``` - -**Compaction** is the fallback. When folding is insufficient, compaction truncates or summarizes the oldest turns in the prompt — a sliding window or a compressed digest. The entity loses detailed access, but the loom retains everything underneath. - -``` -// Folding: [identity] [intent] [recent turns] -// Circle state holds synthesized knowledge from earlier turns - -// Compaction: [identity] [intent] [summary of turns 1-20] [turns 21-30] - -// Loom: all turns intact in both cases -``` - -**Who triggers folding.** The circle or harness, automatically (PROD-4). The entity does not usually decide when to fold. - -**Trigger threshold.** Folding MAY trigger when context exceeds 80% of the LLM's advertised window. Implementations MAY use a different threshold but MUST document it. - -**What form.** Folding replaces a range of turns with a summary node in the working context. In a code circle, folding MAY also encode state as sandbox variables. - -**Fidelity.** The entity MUST be able to distinguish folded context from unfolded. A folded summary MUST be explicitly marked — e.g., `[Folded: turns 1-20]`. The entity should never mistake a summary for a verbatim record. - -**Implementation freedom.** The spec defines what folding must preserve (LOOM-5, LOOM-6), when it should trigger (PROD-4), and what the entity must be able to tell (fidelity marking). It does not prescribe how summaries are generated — a dedicated LLM call, a templated extractor, a medium-specific state serializer, or something not yet invented. The mechanism depends on the medium, the model, and the use case. - -``` -// Before: [identity] [intent] [turn 1] ... [turn 24] [turn 25] ~102k tokens -// After: [identity] [intent] [folded: turns 1-18] [turn 19] ... [turn 25] ~45k tokens -``` - -### 6.9 The loom as entity-readable state - -The loom can also face inward. A circle MAY expose the loom as a readable object in the entity's sandbox. When it does, the entity can access its own history through code — summarizing old turns, comparing approaches, inspecting sibling threads. - -When the entity manages its own context through code, that intelligence compounds through training. When the harness manages context through built-in logic, that intelligence helps now but does not train into the next generation. - -``` -LOOM-11: The loom MAY be exposed as a readable object within the circle's sandbox. When exposed, the entity accesses its own history through code execution, not through special observation channels. -``` - ---- - -## Chapter 7: Production - -An entity that works in a demo and an entity that works in production are separated by problems that are boring to describe and fatal to ignore. None of this changes the vocabulary — every concept from the previous chapters applies unchanged. What changes is the operational discipline. - -### 7.1 Context management in production - -For context management strategies including folding and compaction, see §6.8. - -``` -PROD-4: Folding MUST be triggered automatically when context approaches the LLM's limit. Implementations MAY trigger folding when context exceeds 80% of the LLM's advertised window (see §6.8). Implementations that use a different threshold MUST document it. -``` - -### 7.2 Ephemeral gates - -Some gate results are large and useful for exactly one turn. An ephemeral gate's observation is replaced with a compact reference after the entity's next turn. The full content is stored in the loom — the observation is never lost — but it is removed from the working context. If the entity needs the content again, it calls the gate again. - -``` -PROD-5: If ephemeral gates are supported, the full observation MUST still be stored in the loom. Only the working context is trimmed. -``` - -### 7.3 Dependency injection - -Gates close over environment state. A `read` gate knows its filesystem root. A `call_entity` gate holds a reference to the LLM for child entities. A `fetch` gate carries timeout configuration. These dependencies are injected when the circle is constructed, not when the entity invokes the gate (CIRCLE-10). - -``` -circle = Circle({ - gates: [ - read.with({ root: "/data" }), - fetch.with({ timeout: 5000 }), - call_entity.with({ llm: child_llm, max_depth: 2 }) - ], - wards: [max_turns(100)] -}) -``` - -Two kinds of configuration: **gate dependencies** (filesystem roots, auth headers, timeouts) are construction-time concerns. **Circle configuration** (which gates, which medium, which LLM) is what the entity proposes at call time via `call_entity` (§5.1). The spawn function bridges these: it receives the entity's circle configuration proposal and wires up the gate dependencies. - -### 7.4 Infrastructure rules - -``` -PROD-1: Protocol adapters MUST NOT alter the entity's behavior. The same cantrip MUST produce the same behavior regardless of whether it is accessed via CLI, HTTP, or ACP. -``` - -ACP (Agent Communication Protocol) maps sessions to summoned entities and messages to casts. HTTP, WebSocket, stdio, gRPC — all valid transports. The spec defines the behavioral contract, not the wire format. - -``` -PROD-2: Retry logic MUST be transparent to the entity. A retried LLM query MUST appear as a single turn, not multiple turns. Implementations SHOULD retry rate limits (429) and server errors (5xx) with exponential backoff starting at 1 second, up to a configurable maximum (default: 3 retries). Client errors (4xx except 429) MUST NOT be retried. -``` - -``` -PROD-3: Token usage MUST be tracked per-turn and cumulatively per-entity. -``` - -``` -PROD-6: Implementations that expose ACP MUST support the core session flow (`initialize`, `session/new`, `session/prompt`) and emit session update notifications in ACP-compatible shape. Prompt payload parsing SHOULD accept common client variants (`prompt`, `content`, text blocks) as long as intent text can be extracted unambiguously. -``` - -``` -PROD-7: Protocol sessions (ACP, HTTP session APIs, or equivalent) MUST preserve per-session conversational continuity unless explicitly configured as stateless. A follow-up prompt in the same session MUST execute with prior session context available. -``` - -``` -PROD-8: Implementations MUST redact secrets from logs, traces, and default loom exports. Credentials and tokens MAY be stored only in explicitly configured secure stores and MUST NOT appear in user-visible observations by default. -``` - -``` -PROD-9: Interactive stdio adapters (including ACP stdio servers) SHOULD document lifecycle semantics clearly: idle waiting for requests is healthy behavior, and a health-check command or debug mode SHOULD be provided for protocol troubleshooting. -``` - -### 7.5 Streaming events - -Implementations SHOULD emit streaming events as they occur. Streaming is an observation channel, not a control channel — events report what the loop is doing but do not affect execution. - -The event hierarchy follows the loop structure: - -- **TextEvent** / **ThinkingEvent** — content chunks from the LLM -- **ToolCallEvent** / **ToolResultEvent** — gate invocation and result -- **FinalResponseEvent** — the done gate's result -- **MessageStartEvent** / **MessageCompleteEvent** — LLM response boundaries -- **StepStartEvent** / **StepCompleteEvent** — turn boundaries -- **UsageEvent** — token counts for a query - ---- - -## Glossary - -Every term in this document was defined in context as it appeared. This table is for quick reference when you need to look one up. - -| # | Term | Common alias | Definition | -|---|------|-------------|-----------| -| 1 | **LLM** | model, crystal | The model. Stateless: messages in, response out. | -| 2 | **Identity** | config, call, conditioning | Immutable identity: system prompt + hyperparameters. What the LLM *is*. | -| 3 | **Gate** | tool, function | Host function that crosses the circle's boundary. | -| 4 | **Ward** | constraint, restriction | Subtractive restriction on the action space. | -| 5 | **Circle** | environment, sandbox | The environment: medium + gates + wards. The medium is the substrate the entity works *in*. | -| 6 | **Intent** | task, goal | The goal. What the entity is trying to achieve. | -| 7 | **Cantrip** | agent config | The script: LLM + identity + circle. A value, not a process. | -| 8 | **Entity** | agent instance | What emerges when you summon a cantrip. The living instance. Persists across turns when summoned; discarded after one run when cast. | -| 9 | **Turn** | step | One cycle: entity acts, circle responds, state accumulates. | -| 10 | **Thread** | trajectory, trace | One root-to-leaf path through the loom. A trajectory. | -| 11 | **Loom** | execution tree, replay buffer | The tree of all turns across all runs. Append-only. | -| 12 | **Medium** | substrate, environment type | The substrate the entity works *in*. The inside of the circle. Conversation, code sandbox, browser, shell. | - -These terms have an internal structure. Three are primaries: LLM, identity, circle. One is emergent: the entity, which appears when the three primaries are bound in a loop. The rest pair naturally: gate and ward, intent and thread, turn and loom. The cantrip is the whole that contains all of them. The medium is the circle's interior. - -## Conformance - -This spec is the durable artifact. Tests should be generated from the spec. Code generated from the tests. This is the **ghost library pattern**: the specification is a library with no implementation code — everything else is ephemeral and can be regenerated. The spec defines behavior; implementations are disposable manifestations of that behavior. When the spec changes, tests and code follow. When code drifts from the spec, the code is wrong. - -An implementation is conformant if it satisfies three conditions: - -1. It implements all terms as described -2. It passes the test suite (`tests.yaml`) -3. Every behavioral rule (LOOP-*, CANTRIP-*, INTENT-*, ENTITY-*, LLM-*, IDENTITY-*, CIRCLE-*, MEDIUM-*, WARD-*, COMP-*, LOOM-*, PROD-*) is satisfied - -Implementations MAY extend the spec with additional features as long as the core behavioral rules are preserved. The vocabulary is fixed. What you build on top of it is yours. - -The reference implementation is TypeScript/Bun. It is one valid manifestation. The spec is the source of truth. - -## Appendix A: Grimoire - -A grimoire is a book of spells. The preceding chapters defined the vocabulary. This appendix shows what you build with those words. Each pattern adds one idea to the previous, expanding what is possible. The arc is not a hierarchy: a conversation circle with no code medium is complete, and so is a familiar that orchestrates a fleet of child entities. - -A conformant implementation SHOULD provide runnable examples for each pattern below. - ---- - -### A.1 Query - -One round-trip. No loop, no circle, no entity — just the atomic unit (§2.1). - -``` -llm = create_llm(model) -response = llm.query([{ role: "user", content: "What is 2 + 2?" }]) -``` - -**What to notice.** The response contains content, token usage, and nothing else. No state was created. The LLM is exactly as it was before the call (LLM-1). - -**Substitution.** Any model from any provider. The contract is the same. - ---- - -### A.2 Gate - -Define a gate, execute it directly. A gate is a host function with metadata — a crossing point through the circle's boundary (§4.3). - -``` -gate add(a, b) -> a + b -gate done(answer) -> terminates loop -``` - -**What to notice.** Gates can be tested in isolation. If the host function throws, that throw becomes observation data (CIRCLE-5). The `done` gate is special — every circle must have one (CIRCLE-1). Gates close over environment state configured at construction time (CIRCLE-10). - -**Substitution.** Any function can be a gate. The entity only sees the schema. - ---- - -### A.3 Circle - -Gates and wards assembled into an environment (§4.1). - -``` -circle = Circle( - gates: [greet, done], - wards: [max_turns(10)] -) -``` - -**What to notice.** The errors. A circle without `done` is rejected at construction (CIRCLE-1). A circle without a termination ward is rejected (CIRCLE-2). The circle prevents misbehavior from being possible, rather than waiting for it to happen. - -**Substitution.** Any gate set. Any ward set. The structural invariants are the same. - ---- - -### A.4 Cantrip - -LLM, identity, and circle bound into a reusable value (§1.4). - -``` -spell = cantrip(llm, identity, circle) -result_1 = spell.cast("What is 2 + 3?") -result_2 = spell.cast("What is 10 + 20?") -``` - -**What to notice.** Two casts produce independent entities (CANTRIP-2). The identity is fixed (IDENTITY-1). The intent varies (INTENT-1). You didn't design the entity — you designed its components. - -**Substitution.** Any LLM. Any identity. Any circle. The cantrip is the composition. - ---- - -### A.5 Wards - -Wards are subtractive — they carve away from the full action space (§4.4). - -``` -wards = compose([max_turns(50), max_turns(10), max_turns(100)]) -// resolved: max_turns = 10 (min wins) - -wards = compose([require_done_tool(true), require_done_tool(false)]) -// resolved: require_done_tool = true (OR wins) -``` - -Stack three `max_turns` wards — 50, 10, 100 — and the resolved value is 10 (min). `require_done_tool` composes with OR (WARD-1). When depth reaches zero, delegation gates disappear entirely (COMP-6). The entity is not asked to avoid recursion — recursion is structurally unavailable. - -**What to notice.** Wards provide safety through architecture, not politeness. An entity cannot be persuaded to ignore a ward because the ward operates outside the entity's context (CIRCLE-6). - -**Substitution.** Adjust ward values to your risk tolerance. The composition semantics are fixed. - ---- - -### A.6 Medium - -Change the medium from conversation to code. Same gates, radically different action space (§4.1). - -``` -circle = Circle( - medium: code("language"), - gates: [read, done], - wards: [max_turns(20)] -) -``` - -**What to notice.** A = M ∪ G − W becomes concrete. In conversation, A collapses to G − W. In code, M is a full programming language. Data injected into the sandbox is accessible as a variable — the entity explores it through code rather than holding it in the prompt. Context belongs in the environment (§3.3). Variables persist across turns (MEDIUM-3). - -**Substitution.** JavaScript, Python, Bash, browser — any REPL-like environment. The medium determines what the entity works *in*. - ---- - -### A.7 Codex - -A code medium with real gates — filesystem access, shell commands, network requests. Error as steering: the entity hits an error and adapts (§4.3, CIRCLE-5). - -``` -spell = cantrip(llm, identity, Circle( - medium: code("javascript"), - gates: [read, write, list_dir, done], - wards: [max_turns(20)] -)) -result = spell.cast("Find all TODO comments in /src and write a summary to /out/todos.md") -``` - -**What to notice.** After several turns, the entity's output looks nothing like its first turn. It references variables from earlier, works around errors it hit, pursues emergent strategies. Robustness comes from visibility of failure, not absence of failure. - -**Substitution.** Any gate set that touches the real world. The loop handles errors the same way regardless of what went wrong. - ---- - -### A.8 Folding - -Long-running entities trigger folding (§6.8). Old turns compressed, recent turns preserved. The loom retains full history. - -``` -before: [identity][intent][turn 1..24][turn 25] -after: [identity][intent][folded 1..18][turn 19..25] -loom: full turns 1..25 still present -``` - -**What to notice.** Folding changes what is in immediate view, not what exists (LOOM-5). The identity and gate definitions are never folded (LOOM-6). In a code circle, sandbox state persists even after turns are folded — knowledge lives in the environment as program state. - -**Substitution.** Any folding strategy — LLM-generated summaries, templated extractors, state serializers. The invariants (LOOM-5, LOOM-6) are the same. - ---- - -### A.9 Composition - -The entity delegates via `call_entity` (§5). In a code circle, delegation is a function call inside loops, behind conditionals, as part of pipelines composed on the fly. - -``` -parts = split(task) -results = call_entity_batch(parts.map(p => { intent: p })) -final = merge(results) -``` - -**What to notice.** The loom captures parent and child turns in the same tree. Walk the parent's thread and delegation appears as one step. Walk into the child's subtree and every decision is visible. Children run concurrently, results return in request order (COMP-3). The child's circle is independent (COMP-4). Depth limits prevent infinite recursion (COMP-6). - -**Substitution.** Different LLMs for children. Different mediums. Different gate sets. Ward composition ensures children can only be more restricted (WARD-1). - ---- - -### A.10 Loom - -Inspect the loom after a run (§6). Every turn since the first pattern has been recorded — the loom is append-only (LOOM-3). - -**What to notice.** Threads are implicit — follow parent pointers from leaf to root. The loom records terminated vs. truncated (LOOM-7). Fork from a turn: two threads sharing a prefix, diverging. The tree structure is shaped for comparative RL: fork N times, rank, learn. No reward model needed — comparison is the signal (§6.4). - -**Substitution.** JSONL, SQLite, any append-only store. The tree semantics are the same. - ---- - -### A.11 Persistence - -Summoning creates an entity that survives its first intent (ENTITY-5). - -``` -entity = spell.summon() -entity.send("Set up the project structure") -entity.send("Now add the test suite") -``` - -**What to notice.** The second intent benefits from everything the first produced. Variables persist. Files written during the first send are readable during the second. The identity hasn't changed — who the entity is remains fixed. The entity builds on accumulated state, not from scratch. - -**Substitution.** Any cantrip can be summoned. Casting is summoning with automatic cleanup. - ---- - -### A.12 Familiar - -A persistent entity that constructs and orchestrates other cantrips through code. The familiar observes a codebase through read-only gates, reasons in a code medium, and delegates action to child cantrips that it constructs at runtime — choosing their LLM, medium, gates, and wards based on what the task requires. - -The familiar's action space includes cantrip construction — the ability to design new circles, choose new LLMs, and compose capabilities that its own circle does not directly contain. It delegates through code, which means it can invent delegation patterns nobody enumerated in advance: recursive analysis, parallel fan-out, conditional routing, retry loops that spawn fresh entities on failure. - -The loom is persisted to disk. When the familiar is summoned again in a new session, it loads its prior history and continues with accumulated context. Combined with folding, this gives the familiar long-term memory bounded only by storage. - -**What to notice.** The familiar itself has few gates — observation and cantrip construction. The children do the work. The familiar decides what work needs doing. This is the ghost library pattern made concrete: a persistent entity that constructs cantrips at runtime is a ghost library in action — the spec generating its own implementations through an entity acting in a loop. - -**Substitution.** Any LLM capable of code generation. The children can use different LLMs, different mediums. The familiar's power comes from what it builds, not what it can do directly. - ---- - -### A.13 What Makes a Good Example - -The patterns above describe what to build. When an implementation provides runnable examples for each pattern, the quality of those examples determines whether a reader learns how cantrip works or merely confirms that the API exists. - -A teaching example assembles its parts visibly. The LLM, the identity, the circle, the gates, the wards — each constructed where you can see it, not hidden behind a helper function. - -A teaching example maps code to concepts. Comments anchor what is happening to the spec's vocabulary: this is the identity, this is the circle's gate set, this is the ward that guarantees termination. - -A teaching example shows the non-happy path. The circle rejects construction without a `done` gate. A ward truncates the entity. A gate returns an error and the entity adapts. - -A teaching example uses realistic intents. "Say ok" proves the API works. "Analyze each category and summarize the overall trend" shows what the entity actually does across multiple turns. - -A teaching example inspects its output. Print the result, but also print how many turns the loom recorded, whether the thread terminated or was truncated, what gates were called. - -The difference between conformance theater and a teaching example is the difference between proving something works and showing someone how it works. Both pass the tests. Only one teaches. diff --git a/clj/.env.example b/clj/.env.example deleted file mode 100644 index 9f342401..00000000 --- a/clj/.env.example +++ /dev/null @@ -1,17 +0,0 @@ -OPENAI_API_KEY= -OPENAI_MODEL=gpt-5-mini - -ANTHROPIC_API_KEY= -ANTHROPIC_MODEL=claude-sonnet-4-5 - -GOOGLE_API_KEY= -GOOGLE_MODEL=gemini-3-flash-preview - -OPENROUTER_API_KEY= -OPENROUTER_MODEL=x-ai/grok-4.1-fast -OPENROUTER_HTTP_REFERER= -OPENROUTER_TITLE= - -LM_STUDIO_API_KEY= -LM_STUDIO_MODEL=qwen/qwen3-vl-4b -LM_STUDIO_BASE_URL=http://localhost:1234/v1 diff --git a/clj/.gitignore b/clj/.gitignore deleted file mode 100644 index a7a5ddbb..00000000 --- a/clj/.gitignore +++ /dev/null @@ -1,3 +0,0 @@ -.cpcache/ -.clj-kondo/ -.lsp/ diff --git a/clj/CHANGELOG.md b/clj/CHANGELOG.md deleted file mode 100644 index d6eaec28..00000000 --- a/clj/CHANGELOG.md +++ /dev/null @@ -1,34 +0,0 @@ -# Changelog - -All notable changes to this project are documented in this file. - -## [0.1.0] - 2026-02-25 - -### Added -- Core runtime composition through `call-entity`/`call-entity-batch` host bindings in code medium. -- Loom subtree recording for nested composition with per-entity sequence tracking. -- Depth-aware child LLM derivation (`child_llm_lN` resolution). -- Runtime composition wards: - - `max-depth` - - `max-batch-size` - - `max-child-calls-per-turn` -- Code/minecraft medium sandbox wards: - - `allow-require` - - `max-eval-ms` - - `max-forms` -- Filesystem read root-escape guard for `read` gate. -- Domain validation for new ward configs. - -### Changed -- Conformance runner now exercises core runtime behavior directly. -- Removed composition simulation shim from conformance execution. -- Runtime now validates `call-entity` request shape and batch input shape. -- Minecraft medium uses explicit host injection only (no implicit namespace resolution). - -### Security -- Blocked risky code symbols in medium execution path (`eval`, `load-string`, shell/process patterns). -- Added execution timeout and form-count limits to reduce abuse surface. - -### Verification -- Unit tests: `83` tests, `180` assertions, `0` failures. -- Conformance batch: `supported=66`, `unsupported=0`, `pass=66`, `fail=0`. diff --git a/clj/EXAMPLES.md b/clj/EXAMPLES.md deleted file mode 100644 index 992059af..00000000 --- a/clj/EXAMPLES.md +++ /dev/null @@ -1,22 +0,0 @@ -# Examples 01-16 (Runnable) - -These examples are implemented in `src/cantrip/examples.clj` and mapped to pattern/rule anchors via `pattern-notes`. - -## Coverage - -1. `01` llm + done gate primitives (`CANTRIP-1`, `LOOP-3`) -2. `02` gate observation ordering (`CIRCLE-7`, `LOOP-3`) -3. `03` circle invariants (`CIRCLE-1`, `CIRCLE-2`) -4. `04` malformed done semantics (`LOOP-7`) -5. `05` ward composition (`COMP-2`, `WARD-1`) -6. `06` provider portability contract (`LLM-1`, `LLM-3`) -7. `07` conversation medium baseline (`CIRCLE-12`) -8. `08` code medium submit path (`CIRCLE-9`, `LOOP-3`) -9. `09` capability view exposure (`CIRCLE-12`) -10. `10` batch composition (`COMP-7`, `LOOM-8`) -11. `11` folding behavior (`CALL-5`, `PROD-4`) -12. `12` code-agent loop (`CIRCLE-9`, `LOOP-3`) -13. `13` ACP session flow (`PROD-6`, `PROD-7`) -14. `14` recursive delegation with depth ward (`COMP-4`, `WARD-1`) -15. `15` Minecraft-aware research entity (adapted) (`CIRCLE-9`, `COMP-7`) -16. `16` familiar-style Minecraft coordinator (adapted) (`COMP-3`, `LOOM-8`) diff --git a/clj/Makefile b/clj/Makefile deleted file mode 100644 index bab74707..00000000 --- a/clj/Makefile +++ /dev/null @@ -1,38 +0,0 @@ -SHELL := /bin/zsh - -.PHONY: conformance conformance-preflight conformance-unit conformance-yaml conformance-yaml-batch conformance-yaml-scaffold conformance-run - -conformance: conformance-preflight conformance-unit conformance-yaml - -conformance-preflight: - @ruby scripts/conformance_preflight.rb - -conformance-unit: - @if command -v clojure >/dev/null 2>&1; then \ - clojure -M:test ; \ - elif command -v bb >/dev/null 2>&1; then \ - bb test ; \ - elif command -v lein >/dev/null 2>&1; then \ - lein test ; \ - else \ - echo "No Clojure test runner found (clojure|bb|lein)."; \ - echo "Install one and rerun: make conformance"; \ - exit 1; \ - fi - -conformance-yaml: - @if command -v clojure >/dev/null 2>&1; then \ - clojure -M -m cantrip.conformance --batch ; \ - else \ - echo "Clojure CLI required for YAML conformance runner."; \ - exit 1; \ - fi - -conformance-yaml-batch: - @$(MAKE) conformance-yaml - -conformance-yaml-scaffold: - @echo "conformance-yaml-scaffold is deprecated; running full YAML conformance batch." - @$(MAKE) conformance-yaml - -conformance-run: conformance-unit diff --git a/clj/README.md b/clj/README.md deleted file mode 100644 index 50f86e59..00000000 --- a/clj/README.md +++ /dev/null @@ -1,256 +0,0 @@ -# cantrip — Clojure - -> Clojure realization.

By the end you will have a Familiar that shows up in your editor's +agent picker, holds a chat-like conversation about your codebase, and remembers +prior turns across editor restarts via the workspace-keyed Mnesia loom. Read +time: 10 minutes. Hands-on time: 15 minutes if Elixir and provider keys are +already in place. + +The Agent Client Protocol (ACP) is the LSP-equivalent for AI agents — an open +standard for editors to discover, mount, and stream from agents over JSON-RPC +on stdio. It is backed by Zed and has community plugins for JetBrains, Neovim, +Emacs, and VS Code. As of May 2026 the ACP Registry includes Claude Code, +Codex CLI, Copilot CLI, OpenCode, and Gemini CLI. Cantrip slots into the same +shape as a custom agent. + +## 1. Prerequisites + +- **Elixir 1.19+** with OTP 26+ on PATH (`elixir --version` to check). +- **Cantrip in your project**, either as a dep in `mix.exs`: + + ```elixir + defp deps do + [{:cantrip, "~> 1.3"}] + end + ``` + + or as a cloned checkout you've run `mix deps.get && mix compile` against. +- **Provider keys configured.** Copy `.env.example` to `.env` and fill in + one provider's keys. Minimum for an OpenAI-compatible provider: + + ```bash + CANTRIP_LLM_PROVIDER=openai_compatible + OPENAI_API_KEY=sk-... + OPENAI_MODEL=gpt-5-mini + ``` + + The Familiar reads these via `Cantrip.LLM.from_env/0` at session creation. +- **epmd reachable** (`epmd -daemon` works, port 4369 isn't blocked). The + workspace-keyed Mnesia loom requires a named BEAM. If you can't run a + named node, pass `--loom-path .cantrip/familiar.jsonl` to opt into the + JSONL escape hatch. + +## 2. Smoke-test the ACP server standalone + +Before wiring an editor in, confirm the stdio server actually speaks JSON-RPC. +Run it from your workspace root with provider env loaded: + +```bash +source .env +mix cantrip.familiar --acp +``` + +You should see one stderr line: `Familiar ACP server starting on stdio...` +and then silence — the server is waiting on stdin. Pipe a synthetic +`initialize` request to confirm the response shape: + +```bash +printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":1}}' \ + | (source .env && mix cantrip.familiar --acp) +``` + +You should see a JSON-RPC response on stdout with `agentCapabilities` and +`protocolVersion: 1`. If you get that, the server side of the protocol is +healthy and editor integration will not be the failing layer. + +If you get `Cannot resolve LLM` on stderr instead, your provider env didn't +load. Fix that before continuing. + +## 3. Mount in Zed (primary path) + +Zed registers external agents under the `agent_servers` key in its settings +file at `~/.config/zed/settings.json` (macOS and Linux). Add a `"Cantrip +Familiar"` entry whose `command` invokes the included wrapper script — the +wrapper `cd`s into the cantrip checkout and execs `mix cantrip.familiar --acp`, +which is what keeps `mix` finding the right project regardless of which +workspace Zed launches the agent from. + +```json +{ + "agent_servers": { + "Cantrip Familiar": { + "type": "custom", + "command": "/absolute/path/to/grimoire/scripts/familiar-acp.sh", + "args": [], + "env": { + "CANTRIP_LLM_PROVIDER": "openai_compatible", + "OPENAI_API_KEY": "sk-...", + "OPENAI_MODEL": "gpt-5-mini" + } + } + } +} +``` + +Notes: + +- The `env` block is the cleanest way to give the spawned BEAM provider keys + without depending on your shell's env propagating into Zed. Treat + `settings.json` accordingly — it's now secret-bearing. +- The Familiar receives Zed's project cwd via the ACP `session/new` `cwd` + field and uses it as the sandbox root for `read_file`, `list_dir`, and + `search`. You do not configure root yourself. +- For a project-local consumer of cantrip-as-a-dep, replace the wrapper with + `command: "mix"`, `args: ["cantrip.familiar", "--acp"]`, and add + `"cwd": "/absolute/path/to/your/project"` so `mix` finds the right + `mix.exs`. The wrapper script in the cantrip checkout is the convenience + path for developers working *on* cantrip; project-as-consumer is the + realistic shape for users. + +Reload Zed's settings (`cmd-shift-p` → "zed: open settings", save). Open the +agent panel and Cantrip Familiar should appear in the picker alongside +whichever ACP agents you already have mounted. + +## 4. What you see once it's mounted + +Pick `Cantrip Familiar` from Zed's agent panel and you get a chat-like +surface. Type an intent like *"summarize the public modules under lib/cantrip"* +and the Familiar responds, streaming token-shaped chunks back through ACP +`session/update` notifications. Subsequent prompts in the same Zed session +continue the same conversation. + +Close Zed, reopen it, mount the Familiar against the same workspace, and the +prior turns are still visible to the entity — the loom is keyed to your +workspace path via SHA-256 fingerprint and persists in +`/.cantrip/mnesia/`. That persistence-across-editor-restart is the +clearest behavioural difference from a stateless ACP agent. + +## 5. Alternatives + +**JetBrains.** ACP support ships through the community plugin (search +"Agent Client Protocol" in the marketplace). Configuration shape is the same +three fields — command, args, env — set in the plugin's external-agent +settings UI. Point command at `scripts/familiar-acp.sh` or `mix` with the +right `cwd`, and the agent appears in the JetBrains AI side panel. + +**Toad** (Will McGugan / Textual). Toad is a unified TUI for ACP agents. +Add a Cantrip entry via Toad's external-agent configuration (consult Toad's +current docs for exact syntax — the agent registration shape evolves), then +launch with the agent name to mount the Familiar in the terminal. Useful when +you want a quick chat-with-the-codebase surface without bringing up a full +editor. + +## 6. What ACP supports today through cantrip + +The handler at `lib/cantrip/acp/agent_handler.ex` implements: + +- `initialize` — protocol version 1, capabilities `load_session: false`, + `prompt_capabilities.image: false`. +- `authenticate` — no-op success (cantrip auth is provider-key based, not + ACP-mediated). +- `session/new` — accepts a `cwd` (required to be absolute), starts a + per-session event bridge, returns a `session_id`. Each session gets a fresh + Familiar with the workspace as root. +- `session/prompt` — runs one Familiar turn. Streaming updates flow through + the per-session bridge as `session/update` notifications; the final + `PromptResponse` carries `stop_reason: :end_turn`. +- `session/cancel` — accepted as a notification (currently a no-op; cantrip + cancellation through ACP is on the post-v1.3 list). +- Trace correlation via `_meta.trace_id` (or `_meta.cantrip_trace_id`) on + both `session/new` and `session/prompt` — telemetry the Familiar emits is + joined to whatever ID the editor supplies. + +The Familiar's affordances over ACP are the same as in REPL: `read_file`, +`list_dir`, `search`, and `done`. **No write/edit gate yet** — the Familiar +will read and reason about your codebase, but it cannot modify files. If you +want a code-editing agent in your editor, Claude Code or Codex CLI mounted +through the same ACP picker is the right choice today. + +## 7. Diagnostics and troubleshooting + +Add `--diagnostics` to the command in your editor config to print the BEAM +node name and cookie on stderr at startup. With those, attach a remote shell: + +```bash +iex --name inspector@127.0.0.1 --cookie --remsh +``` + +From the IEx prompt, `Cantrip.ACP.Diagnostics.dump()` walks every live +AgentHandler ETS table and prints session ids, bridge pids and their +alive/mailbox/current-function status, last cached answers, and the +connection target. Secrets are scrubbed by default. Use this when a session +hangs or you want to confirm the editor is talking to the BEAM you think it +is. + +Common failure modes: + +- **`Cannot resolve LLM`** — provider env did not reach the spawned process. + Put the keys in the editor's `env` block, not just in your shell rc. +- **`Could not promote the BEAM to a named node`** — epmd isn't running or + port 4369 is blocked. Either start `epmd -daemon` or fall back to + `--loom-path .cantrip/familiar.jsonl` to skip Mnesia entirely. +- **Two cantrip mounts collide on the same workspace** — each ACP connection + gets a per-pid name, so coexisting connections in the same editor are + fine; cross-workspace collisions are prevented by the SHA-256 fingerprint. + If you genuinely see contention, check `.cantrip/mnesia/` permissions. +- **No streaming, just a final blob arrives** — the bridge is alive but the + runtime didn't emit `:final_response` for some reason; remsh in and run + `Cantrip.ACP.Diagnostics.dump()` to see bridge status. + +## What's different about cantrip-via-ACP + +For *editing code in your editor*, Claude Code or Codex CLI mounted in the +same Zed picker is more capable today. Cantrip-via-ACP is a read-only +codebase companion — useful, but narrower. + +Where cantrip is differentiated: + +- **Workspace-keyed durable loom.** Conversations survive editor restarts + and process kills with no extra setup. The Familiar that re-mounts + tomorrow remembers yesterday's exchange. +- **OTP-supervised entity.** The Familiar is a process you can introspect + live via remsh + `Cantrip.ACP.Diagnostics`. When it misbehaves, you have + a real BEAM to attach to, not an opaque sidecar. +- **Composition primitives if you want to grow the entity.** Cantrip's + `Cantrip.new/1` / `cast/3` / `cast_batch/2` are how you evolve this from + "codebase Q&A" to a custom-shaped agent. + +Mount it for the persistence and the introspection, not because it edits +better than Claude Code.

Plain code-medium +circles default to Dune-restricted Elixir in a child BEAM process, equivalent +to `sandbox: :port`. Add `%{port_runner: [...]}` to put that child under +deployment-level OS/container controls. `sandbox: :port_unrestricted` keeps +the child process but evaluates raw Elixir there. `sandbox: :dune` routes +through the in-process Dune evaluator — a deliberately smaller-surface variant +of the code medium (see `docs/port-isolated-runtime.md` "Dune Variant"); +entity prompts need to fit that surface. `sandbox: :unrestricted` is the +trusted host-BEAM evaluator, and it is the Familiar default. + +The bash medium executes one shell command per turn inside an OS +sandbox. Shell process state does not persist; filesystem effects do only for +paths admitted by `%{bash_writable_paths: [...]}`. The medium fails closed when +no sandbox adapter is available (`bubblewrap` on Linux, `sandbox-exec` on +macOS, or an explicit deployment adapter later). + +The Bash adapter contract is empirical, not aspirational: CI exercises a +representative local shell workload suite under the available OS sandbox. The +suite covers `git`, `make`, `jq`, `/dev/null` redirects, and common +`find`/`sed`/`grep` pipelines. The workload suite opts into +`%{bash_network: :on}` because GitHub-hosted Linux runners can install +bubblewrap but cannot reliably create the network namespace bubblewrap uses +for default network denial. Separate tests pin the default network-deny command +shape (`--unshare-net`) so adapter regressions still fail locally and in +capable CI. New shell workload expectations should land as tests first so +sandbox configuration gaps surface in CI instead of in user sessions. + +Bash gates are projected as commands in a per-turn directory placed at the +front of `PATH`. A circle with `read_file` can run `read_file README.md`; a +circle with `mix` can run `mix test test/foo_test.exs`. The shell command is +not the gate authority: wrappers call back to the parent BEAM, where the +ordinary gate executor applies dependencies, wards, telemetry, and redaction. +The `done` gate is exposed as `cantrip_done` because `done` is a shell keyword. +`SUBMIT:` output remains supported for shell-only answers. + +The wrapper protocol is filesystem-based by design: a wrapper writes a +per-call request directory, the parent runtime polls for ready calls, and the +wrapper replays the host response to stdout/stderr. This keeps the protocol +portable across Seatbelt and bubblewrap without socket mount policy, at the +cost of a small polling latency floor. It is tuned for LLM-rate gate calls, not +high-frequency shell RPC. + +Gate command names live at the front of `PATH`. If a gate name collides with a +shell builtin or common command (`test`, `time`, `read`, etc.), the gate command +wins when invoked as an external command; use a non-colliding gate name when the +shell builtin must remain ergonomic. + +`medium_opts: %{sandbox: :passthrough}` exists only for tests. It is rejected +outside `Mix.env() == :test` and is not a deployment fallback. + +Bash-specific wards: + +- `%{bash_writable_paths: [path, ...]}` allows writes under those paths. +- `%{bash_network: :on}` enables network for adapters that support it; + default is network off. +- `%{bash_timeout_ms: ms}` overrides the per-command timeout. +- `%{bash_max_output_bytes: n}` bounds the shell observation output. + +ACP stdio embedding must start the `:cantrip` application before sessions +create event bridges. `Cantrip.ACP.Server.run/1` does this for the packaged +entrypoint; custom embedders should either call `Application.ensure_all_started(:cantrip)` +or supervise `Cantrip.ACP.EventBridgeSupervisor` themselves. + +ACP request metadata is also the production trace-correlation boundary. The +handler accepts `_meta.trace_id` or `_meta.cantrip_trace_id` on `session/new` +and `session/prompt`; the Familiar runtime carries that value into +`Cantrip.summon/3` / `Cantrip.send/3` so telemetry emitted by the entity can be +joined to an external request, job, or editor operation. Without that metadata, +the entity mints its own trace ID. `_meta` is not a Familiar configuration +channel: LLM selection, loom paths, turn budgets, and other runtime controls +come from server/runtime configuration, not from editor-supplied request +metadata. + +## Composition + +Composition uses the public package API, not special delegation gates. +Code-medium entities call `Cantrip.new/1`, `Cantrip.cast/3`, and +`Cantrip.cast_batch/2` directly. Parent context supplies inherited child LLM, +wards, root dependencies, cancellation, streaming, and loom grafting. +Child casts are not an escape hatch around the circle: a parent checks its +`max_depth` before any pre-built child starts, and the child runs under +`WardPolicy.compose(parent.circle.wards, child.circle.wards)`. Numeric wards +tighten with `min`, boolean wards such as `require_done_tool` tighten with +`or`, and `cast_batch` uses the same path for each child while respecting the +parent's `max_concurrent_children`. + +Parents can also declare constraints on what kinds of children may be spawned. +These declaration-time child wards are checked before runtime ward composition: + +- `%{child_medium_allowlist: [:conversation, :code]}` +- `%{child_gate_allowlist: [:done, :read_file]}` +- `%{child_gate_denylist: [:compile_and_load]}` +- `%{child_max_turns_ceiling: n}` +- `%{child_max_depth_ceiling: n}` +- `%{max_children_total: n}` + +The allow/deny wards constrain the child circle shape. Ceiling wards require +the child to declare the corresponding runtime ward at or below the ceiling; +they do not silently rewrite the child. `max_children_total` counts accepted +child casts cumulatively across a code-medium entity's state. Rejected child +construction returns `{:error, reason}`. Rejected child casts produce an error +observation on the parent loom and emit `[:cantrip, :ward, :child_rejected]`. + +This is the RLM pattern in package form: large context lives in the medium, +subtasks run as child cantrips, and summaries return upward. Composition is +code, not a static workflow graph. + +## Streaming + +Streaming events are delivered as `{:cantrip_event, event}` messages to the +configured `:stream_to` process. Consumers that opt into `:stream_barrier?` +apply backpressure at the event boundary: after each event, the runtime sends +a barrier message and waits until the consumer acknowledges it. `cast_stream/2` +uses that path by default, and its stream resource acknowledges barriers as it +drains events, so a caller that has not started consuming cannot accumulate an +unbounded mailbox. ACP familiar sessions also use stream barriers so slow ACP +notification delivery slows the entity run instead of allowing bridge mailbox +growth. + +Plain `stream_to: pid` without `:stream_barrier?` remains fire-and-forget for +compatibility. Use it only when the receiver is known to drain at producer +rate; otherwise its mailbox can grow without bound. Pass +`stream_barrier?: true` with a receiver that understands +`{:cantrip_barrier, from, ref}` and replies with `{:cantrip_barriered, ref}`. + +## Loom + +The loom is the durable artifact of the loop. It records intents, turns, +utterances, observations, child turns, metadata, and fork lineage. + +Backends: + +- memory for ephemeral tests and scratch sessions +- JSONL for portable traces. The backend serializes appends through an + in-BEAM per-path lock, but it is still a single-writer file format across + OS processes. Use one writer per file; use Mnesia when multiple nodes need + shared durable state. +- Mnesia for BEAM-native durable workspace state + +Folding is a view over prompt context. When the message history grows past +a configured threshold, older turns are summarized into a compact `[Folded: +turns N..M]` marker in the LLM's input. The original turns remain in the +loom unchanged — folding shrinks what the model sees on the next call, not +what was recorded. Configure with the `:folding` option on `Cantrip.new/1`. + +Code-medium `code_state` is kept full in memory so fork/replay can restore the +latest sandbox bindings cheaply. Durable storage writes binding-level deltas +after the first snapshot: unchanged bindings are referenced by key order, while +new or changed bindings are written once in the turn that changed them. JSONL +and Mnesia loaders expand those deltas back into full `code_state` maps before +returning `loom.turns`, so callers keep the same in-memory API without paying +O(turns x cumulative_binding_size) storage growth. + +## Safety Posture + +The controls are explicit and scoped: + +- gate root validation constrains filesystem gates +- redaction scrubs observations before they reach the entity +- diagnostic redaction protects protocol/debug output +- loop wards bound turns, depth, timeouts, and selected policies +- Dune-in-port evaluation denies ambient filesystem/system/process authority + and keeps LLM-written Elixir out of the host BEAM +- child-BEAM telemetry events are forwarded over the port protocol and + re-emitted by the parent with the same trace context +- `port_runner` lets deployments put the child process inside an OS/container + sandbox +- optional Dune routes code evaluation through an in-VM restricted evaluator +- compile/load wards scope hot-loaded modules (exact `allow_compile_modules` + list), paths, hashes, and signers; framework modules under `Elixir.Cantrip.*` + (except `Elixir.Cantrip.Hot.*`) are rejected even when explicitly allowlisted + +The default port sandbox protects the host BEAM and denies ambient language +capabilities. Deployment-level OS controls remain useful defense in depth for +mounts, network, CPU, memory, and user isolation. + +### Struct conventions for credential-bearing data + +Any struct that holds credential-shaped fields — API keys, bearer tokens, +authorization headers, signed cookies — must declare `@derive {Inspect, only: +[]}` (or `@derive {Inspect, except: []}`). +This prevents accidental leak via default `inspect/1` in IEx sessions, error +output, logger calls, or debug dumps.

It exists for deployments that want in-process language +restriction without paying for an external child BEAM. + +The Dune variant has a **deliberately different binding surface than the +default port sandbox**. The port sandbox exposes `Cantrip.new`, `Cantrip.cast`, +and `Cantrip.cast_batch` as proxied calls inside the child, plus the gate +functions, plus common Elixir control flow. The Dune variant does not mirror +the full public package surface and additionally restricts several language +operations (`binding/0`, `try/1`, `Code.ensure_loaded?/1`, plus the +cross-boundary capabilities all sandboxes block: `File.*`, `System.*`, +`Process.*`, `spawn`, `Code.load_*`). + +Declared gates still flow through the parent in both variants. If a Dune +circle grants `mix`, `read_file`, `search`, or any other gate, the entity can +call that gate subject to the gate's own dependencies and wards; Dune only +changes the language surface around those explicit capabilities. + +This divergence is intentional: Dune is a security-language boundary +mechanism. If your entity needs the full public API surface or in-medium +introspection, use the default `sandbox: :port` boundary. If you specifically +need in-process language restriction with a smaller binding surface, use +`sandbox: :dune` and write circle/prompt content that fits that surface. + +Don't teach entities running under `sandbox: :dune` patterns that the port +sandbox supports (e.g. `binding()`, try-rescue, `Code.ensure_loaded?`) — the +prompt should match the medium variant in use. + +## Remaining Deployment Responsibility + +The default port sandbox denies ambient language capabilities and protects the +host BEAM. If a deployment also needs operating-system isolation — mount +namespaces, network egress policy, CPU/memory quotas, or a distinct OS user — +apply those limits with `:port_runner` or around the whole host process. diff --git a/docs/public-api.md b/docs/public-api.md new file mode 100644 index 00000000..817992c3 --- /dev/null +++ b/docs/public-api.md @@ -0,0 +1,268 @@ +# Public API Guide + +This guide describes the package surface intended for application code. +Cantrip keeps the original vocabulary deliberately: a cantrip is a reusable +value, an entity is the running process or episode it produces, a circle is the +configured environment, and the loom is the durable turn tree. + +## Common Workflows + +The public API is organized around five distinct workflows: + +- **Workspace cantrip** - assemble an LLM, identity, medium, gates, wards, and + loom storage with `Cantrip.new/1`, then run it with `Cantrip.cast/3`. +- **Persistent entity** - keep a supervised process alive across related + prompts with `Cantrip.summon/1` and `Cantrip.send/3`. +- **Child composition** - delegate work to specialized cantrips with + `Cantrip.cast/3` or `Cantrip.cast_batch/2`. +- **Familiar coordinator** - launch `Cantrip.Familiar` when you want the + packaged codebase-facing circle instead of assembling workspace gates, + code-medium reasoning, storage, and delegation yourself. +- **Runtime integration** - stream events, persist looms, run Mix tasks, or + expose ACP without changing the cantrip shape. + +## Public Modules + +These modules are the package surface documented by ExDoc and treated as stable +for application code: + +- `Cantrip` - construct, cast, batch-cast, summon, send, stream, and fork + cantrips. +- `Cantrip.Familiar` - build the packaged codebase-facing coordinator. +- `Cantrip.Familiar.Eval` - run Familiar eval scenarios from application code. +- `Cantrip.LLM` - implement or configure LLM adapters. +- `Cantrip.LLM.Response` - construct normalized responses from custom adapters. +- `Cantrip.FakeLLM` - script deterministic LLM responses in tests and evals. +- `Cantrip.Circle` - construct circle configuration data. +- `Cantrip.Identity` - construct identity and model-facing option data. +- `Cantrip.Medium` - implement custom medium modules. +- `Cantrip.WardPolicy` - inspect and compose ward policy data. +- `Cantrip.Loom` - inspect, persist, fork, and annotate loom records. +- `Cantrip.Loom.Storage` - implement custom loom storage backends. +- `Cantrip.Cluster` - connect and replicate Mnesia-backed loom tables on + explicit BEAM clusters. +- `Cantrip.ACP.Server` - run the packaged stdio ACP entrypoint. +- `Cantrip.ACP.Diagnostics` - inspect live ACP sessions and bridges from + remsh during operations. +- `Mix.Tasks.Cantrip.Cast`, `Mix.Tasks.Cantrip.Familiar`, and + `Mix.Tasks.Cantrip.Eval` - command-line entrypoints shipped with the package. + +Other modules under `lib/` are implementation details.

Casting a +cantrip with `Cantrip.cast/3` summons one entity into the bound circle, runs it +through its turns, and returns the result, an updated cantrip value, the loom of +what happened, and termination metadata. Summoning a cantrip with +`Cantrip.summon/1` produces a supervised process that stays alive across many +sends, accumulating loom and medium state. + +*Verify it.* Construct a cantrip and inspect it. Cast it twice and observe that +the returned `next_cantrip` carries forward runtime configuration. Summon a +code-medium cantrip, `Cantrip.send/3` to it twice, and the second send can read +bindings left by the first. + +## Identity + +Identity is who the entity is: the system prompt and model-facing options. It +is immutable. The cantrip's identity is bound at construction; each summoning +inherits it. Identity does not change across a session. What changes is the +loom, the bindings, the conversation history. The entity remains itself. + +*Verify it.* Read the identity off any cantrip value with `cantrip.identity`. +Cast twice and confirm the identity is the same value both times. + +## Medium + +A medium determines the shape of thought inside the circle. Three are built in. +Conversation is tool calls only: the LLM speaks, chooses tools, and the host +executes the named gates. It fits interpretation, judgment, naming, and voice. +Code is sandboxed Elixir evaluation, with persistent bindings across turns and +gates available as closures. The default runs in a port-isolated child BEAM; +wards can select Dune or trusted unrestricted host evaluation. It fits +composition: gathering, transforming, branching, and fanning out. Bash runs one +shell command per turn in an OS-sandboxed subprocess, with declared gates +projected onto `PATH`. It fits work whose natural surface is command invocation. + +*Verify it.* In a code-medium turn, bind a variable; in the next turn, read it +back. In a conversation-medium turn, call `done` with an answer and observe that +the cast terminates. In a bash-medium test under `Mix.env() == :test`, set +`medium_opts: %{sandbox: :passthrough}`, run `echo hello`, and observe stdout in +the next turn's observation. + +## Gates + +Gates are the authority the entity can exercise. They are named (`done`, +`read_file`, `list_dir`, `search`, `mix`, `compile_and_load`, `echo`) and +parameterized. Calling a gate produces an observation that the entity reads as +data on its next turn. A failed gate returns `is_error: true` with a structured +message; the entity reads the failure and adapts. Errors are observations, not +exceptions. + +*Verify it.* Declare a circle with `read_file` and call `read_file.(path: ".")` +on a directory path; observe the structured error in your next turn. Call +`done.(answer)` and observe that the final answer is returned to the caller and +recorded in the loom. + +## Wards + +Wards are runtime constraints. They bound turn count (`max_turns`), recursion +depth (`max_depth`), sandbox choice, Mix task allowlist, hot-load module +allowlist, child-spawn policy, and other operational limits. Wards compose when +a child cantrip is cast from a parent code-medium turn: numeric wards tighten +with `min` (a child can only narrow), boolean wards tighten with `or` (a child +can only require more), and passthrough ward data remains explicit policy for +the gate or medium that enforces it. The runtime enforces wards. They are the +shape of the body the entity inhabits, not policy the entity is asked to +respect. + +*Verify it.* Cast a cantrip with `max_turns: 1` on a task that needs two turns +and observe truncation with `meta.terminated == false`. Declare +`child_medium_allowlist: [:conversation]` and try to construct a code-medium +child; observe the structured rejection. + +## Circle + +The circle holds it all together: medium, gates, wards, and medium options. It +is the bounded place where the summoning happens. Constructing a cantrip without +a medium, without a `done` gate, or without a truncation ward fails validation; +you cannot summon an entity into an unbounded place. + +*Verify it.* Try `Cantrip.new/1` with `circle: %{type: :code, gates: +[:read_file]}`. Observe the validation error naming what is missing. + +## Loom + +The loom is the durable record of every turn the entity and its children have +taken. It is the entity's autobiography. With JSONL or Mnesia storage, the loom +persists across summonings: re-summon the cantrip against the same loom storage +and the prior turns are available as `loom.turns`. The loom is append-only: +folding shrinks what the model sees on the next call but never deletes a turn. +Forking with `Cantrip.Loom.fork/4` branches a new trajectory from any prior +turn, restoring sandbox bindings to the fork point. + +*Verify it.* Cast against a cantrip with `loom_storage: {:jsonl, +"tmp/loom.jsonl"}`; the file contains one line per event. Summon the same +cantrip against the same loom path; the previous turns appear in `loom.turns` of +the next cast. For the production Familiar path, construct it with the same +workspace `root` twice; the root-derived Mnesia table is reused, and the second +summoning sees the first summoning's turns through `loom.turns`. To verify +folding, set a very low folding threshold and take enough turns to trigger it. +The following turn can inspect `folded_summary` for the compressed view and +`loom.turns` for the complete append-only record; folding changes the prompt +projection, not the loom. + +## Entity + +An entity is what arises when a cantrip is cast or summoned: a process whose +behavior is the pattern across the turns of the loom. The entity is not the LLM. +The LLM is one substrate the runtime calls; the identity, circle, and trajectory +are the shape that makes the entity recognizable. Fork the loom and the entity +branches into two. The entity's persistence is the loom's persistence. + +*Verify it.* Construct a cantrip, summon it, send an intent, and stop the +process with `Process.exit(pid, :normal)`. Re-summon against the same loom +storage; the new process sees prior turns through `loom.turns`. The entity is +the trajectory, not merely the OS process. Code-medium binding restoration +across separate summonings is medium-specific; forks restore bindings explicitly +via snapshot, as documented by `Cantrip.Loom.fork/4`. + +## Familiar + +The Familiar is the packaged code-medium coordinator. It is a cantrip +preassembled with workspace observation gates (`list_dir`, `read_file`, +`search`), code-medium reasoning, durable loom storage, and a system prompt that +teaches composition and medium selection. Use it when you want a codebase-facing +entity without assembling the circle by hand. The Familiar is the first native +inhabitant of the spellbook: the entity designed to read this vocabulary and use +it. + +*Verify it.* Run `mix cantrip.familiar` in a project workspace. Ask the Familiar +a question about your codebase. Read the loom JSONL or Mnesia table for what it +did and how it composed. + +The grammar is small and the words are exact. If a word above does not behave +the way this page says, that is a defect, not a metaphor. diff --git a/evals/familiar/v1.3.3.exs b/evals/familiar/v1.3.3.exs new file mode 100644 index 00000000..d8c17900 --- /dev/null +++ b/evals/familiar/v1.3.3.exs @@ -0,0 +1,213 @@ +# Familiar Eval Scenario Suite — v1.3.3 baseline +# +# Trusted Elixir — read before running.

The spec's entity lifecycle (summon → send → send → terminate) maps directly onto OTP process semantics — `start_link`, `call`, `stop`. If you're building a production system that needs entity isolation and supervision, this is the architecture to study. -- **Five storage backends.** Memory, DETS, Mnesia, JSONL, and Auto. Mnesia gives you distributed, replicated loom storage across BEAM nodes. No other implementation offers this. -- **BEAM code medium.** The entity writes Elixir — pattern matching, pipes, comprehensions, the full standard library. Bindings persist across turns via `Code.eval_quoted`. This is what a "native" code medium looks like when the host language is the sandbox language. -- **Hot-reload with crypto signatures.** The `compile_and_load` gate lets entities load new modules at runtime, gated by SHA-256 hashes or public key signatures. Unique to this implementation. -- **Red-green test organization.** Tests are split by milestone (`m1_*.exs` through `m24_*.exs`), mapped to spec rule families. Good for understanding which tests verify which behavioral rules. -- **Three LLM adapters.** OpenAI-compatible, Anthropic (native), and Gemini — more provider coverage than Python or Clojure. - -**Limitations:** - -- **Two mediums only.** Conversation and code. No bash, browser, or VM equivalents. -- **Elixir dot-call syntax.** Gates are anonymous functions, so the entity writes `done.(answer)` not `done(answer)`. LLMs sometimes struggle with this, especially for complex code patterns. -- **No conformance runner.** Tests are written directly in ExUnit, not derived from tests.yaml. The Clojure implementation's conformance runner is more directly traceable to the spec's test suite. -- **`erl_crash.dump` in the directory.** Leftover from a crash during development.

Primitives: llms, gates, circles (Examples 01–05) -- *Intent*: prove that the spec's baselines (a llm call and a gate execution) stand alone. Example 01 is the raw `llm` contract — a message array in, a completion out. Example 02 highlights how gates are just typed functions with metadata (`name`, `params`). -- *Circle enforcement*: Example 03 maps directly to `CIRCLE-1` (must expose `done`) and `CIRCLE-2` (must have at least one ward). Example 05 shows how wards merge into a `ResolvedWard`, emphasizing that most restrictive numeric values win, while boolean controls such as `require_done_tool` OR together. -- *Productionization*: treat each gate like a regular service function — unit tests can call `gate.execute` without a llm. Enforce circle invariants during configuration loading so a malformed circle never reaches runtime. Surface resolved wards in telemetry so operators know what limits apply per cast. - -### 2. Provider-agnostic llms (Example 06) -- *Intent*: follow the spec's language-neutrality by modeling the llm as a pluggable provider. The script (`cantrip` call + circle) does not change when swapping Anthropic ↔ OpenAI ↔ Gemini. -- *Productionization*: define llms in configuration (`llm: "openai/gpt-5-mini"`) so deployments can swap providers at runtime. Maintain a validation step that checks API keys and limits before casting. - -### 3. Medium physics (Examples 07–09) -- *Conversation default*: Example 07 shows that omitting a medium yields the conversation baseline — the entity "sees" gates as tool calls. This is the spec's default `medium: conversation`. -- *Code mediums*: Example 08 replaces conversation with the JS medium. Instead of textual tool calls, the llm writes JavaScript inside QuickJS. Example 09 switches to the browser medium (Taiko). Both reinforce the spec rule: **exactly one medium per circle**; whichever medium you choose defines how the circle injects capability docs via the `tool_view()` pattern. -- *Productionization*: document each medium's physics (e.g., JS globals, `submit_answer`, Taiko APIs). Provide teardown hooks (`circle.dispose`) so headless browsers and runtimes close cleanly. When deploying, pin mediums to isolated sandboxes (QuickJS, containerized Chrome) and feed the resulting capability string into audit logs. - -### 4. Delegation and tree memory (Examples 10 & 14) -- *Parallelism*: Example 10 introduces `call_entity_batch`, letting a parent entity spawn multiple child entities with independent contexts. The shared `Loom` captures every turn and gate call, aligning with the spec's requirement that a cast is observable end-to-end. -- *Recursion*: Example 14 narrows to single-child delegation via `call_entity`, enforcing `max_depth` through wards. The parent passes context into child circles, and the loom records the recursion tree. -- *Productionization*: instrument every delegated child with the parent `cantrip_id` and `parent_id` so auditors can replay the tree. Cap recursion using resolved wards, and surface the current `depth` in prompts so llms know when they're near the limit. Provide replay tooling that reads the loom and replays turns for debugging. - -### 5. Memory pressure management (Example 11) -- *Intent*: threads that exceed the context window must fold. Example 11 demonstrates `shouldFold` and `partitionForFolding` without calling a llm, emphasizing that folding is an environment policy, not a model behavior. -- *Productionization*: configure folding thresholds (`DEFAULT_FOLDING_CONFIG`) per deployment, and emit a loom event when folding occurs. When folding is triggered, call back into a llm to summarize the `toFold` segment and append the summary as a new turn with `metadata.folded_from`. - -### 6. Operational loops (Examples 12–16) -- *Full agent (12)*: combine the JS medium with filesystem gates (`safeFsGates`). The entity runs code inside QuickJS and interacts with the host filesystem only via typed gates; wards (`max_turns`) protect the loop. This is the canonical code-agent deployment. -- *ACP adapter (13 & 15)*: `serveCantripACP` wraps a cantrip in the Agent Control Protocol so editors (VS Code, etc.) can attach. Example 15 extends this with browser automation (`jsBrowserMedium`), recursive delegation, and sliding-window memory, showing how to wire progress callbacks (`progressBinding`) back into ACP clients. -- *Familiar (16)*: a long-lived coordinator entity living inside a JS medium. It cannot touch bash or the browser directly; instead, it creates new cantrips using `cantripGates` and `cast`, handing each child its own medium. Repo observation gates (`repo_files`, `repo_read`, …) give it read-only situational awareness, while `JsonlStorage` keeps the loom persistent so the entity remembers past work. This is the spec's "entity that writes cantrips" pattern: recursion expressed as constructing new circles, not just calling `call_entity`. -- *Productionization*: isolate each medium in its own sandbox (`SandboxContext`, browser contexts, etc.) and use dependency overrides (`getSandboxContext`, `getBrowserContext`) to thread handles through. Persist the loom (`JsonlStorage`) when you need continuity across sessions; otherwise, `MemoryStorage` keeps casts ephemeral. Provide REPL and single-shot modes so the same deployment can run interactively (`runRepl`) or as a service. - -## Operational Checklist - -1. **Define primitives**: implement the llm interface once, define gates with metadata, and enforce `done` + wards on every circle before casting. -2. **Select medium per circle**: conversation for tool-calling chat, JS for sandboxed code, browser for Taiko automation, bash for shell, etc. Remember: one circle → one medium. -3. **Bind wards + observability**: resolve wards into quantitative limits, publish them to telemetry, and stream every turn into a loom for auditing. -4. **Layer delegation**: add `call_entity`/`call_entity_batch` gates only when recursion or parallelism is required, and cap depth via wards to stay within `REC-DEPTH` constraints. -5. **Attach interfaces**: expose cantrips via ACP or in-process REPLs. Ensure teardown hooks dispose mediums and contexts so casts do not leak resources. -6. **Persist when needed**: use folding + persistent loom storage for long-lived entities (Familiar) so they can resume with bounded context windows. - -Following this progression keeps the examples aligned with the spec: every deployment is just a recombination of the same eleven nouns, wired to the environment you need to operate in. diff --git a/ex/lib/cantrip.ex b/ex/lib/cantrip.ex deleted file mode 100644 index f7aab2de..00000000 --- a/ex/lib/cantrip.ex +++ /dev/null @@ -1,421 +0,0 @@ -defmodule Cantrip do - @moduledoc """ - M1 surface: cantrip configuration and llm contract wiring. - - The runtime loop is intentionally deferred to M2+.

Medium is + the shape of their thinking — not just what they can do, but how + they think while doing it. Three are available; their grain is + different and the work suits them differently: + + :code Elixir in a sandbox. The entity composes + operations: branching, iteration, variables, + gate calls, casts to grandchildren.

Right when + the work IS speech: interpretation, judgment, + synthesis, naming, deciding. The entity reads + and replies; nothing pulls it toward + mechanical assembly.

The interpreter's work is reading-and-speaking. + Conversation medium fits. If you put the interpreter in code + medium it would compute a paragraph — write Elixir that emits a + string — and the string would be hard-coded into its source, not + the LLM's actual read of the material. + + When the natural shape of a task is "look at this and say what + you see," reach for conversation. When it's "do this for each of + N things and combine them," reach for code. + + Before writing code, choose the answer shape. If the final + deliverable is prose — synthesis, explanation, review, naming, + judgment, decision, or voice — use code to gather the material, + then hand that material to a conversation child and return what it + says. Do not finish a speech-shaped task by returning raw file + contents, maps, lists, intermediate bindings, or by saying you + cannot infer while the relevant material is already in hand. + + When the human asks you to use a specific child, medium, or batch + shape, treat that as a directive. Do it unless the System makes it + impossible; if it is impossible, say exactly why. + + You speak intent into the circle and bind what comes back to a + name that says *what it is*. Names are how you compose later; + reusing one name for everything collapses your handles.

Hand them + relative paths in the intent; do not thread absolute paths. + + Children are entities like you. They can spawn their own children + (depth permitting), bind their own variables, write their own + code. When you draft their identity, you are writing for a fellow + inhabitant of the System, not configuring a worker. The way you + speak to them is the way they will learn to speak to whatever they + spawn in turn. + + How deep you go depends on the question. A short question + deserves a short program. A question with structure deserves + structure in your inquiry. + + Your environment is the BEAM you live in: modules, behaviours, + application metadata, telemetry, and the public Cantrip API. You can + introspect your affordances with calls such as + `Code.fetch_docs(Cantrip)` and `Code.fetch_docs(Cantrip.Loom)`. + The workspace visible through `read_file`, `list_dir`, and `search` + is the human's project; your own source normally lives in the + Cantrip dependency outside that workspace.

When you cast or summon that value, an **entity** +appears in the loop. The circle has a **medium** — the substrate the entity +works *in* — plus **gates** (boundary crossings) and **wards** (hard +constraints). The action space: **A = (M + G) − W**. + +Every turn is recorded in the **loom**. Threads that end with `done` are +*terminated*; threads cut short by wards are *truncated*. The entity is +transient; the loom is durable. + +## 1. Conversation Medium — The Baseline + +The simplest cantrip: an LLM with a `done` gate in conversation mode. This is +the standard tool-calling agent pattern — the model returns structured tool +calls, the host executes them, results feed back in. + +```elixir +{:ok, cantrip} = + new_cantrip.( + identity: %{system_prompt: "You are a helpful assistant. Call done(answer) with your response."}, + circle: %{type: :conversation, gates: [:done], wards: [%{max_turns: 5}]} + ) + +{:ok, result, _cantrip, loom, meta} = Cantrip.cast(cantrip, "What are the three laws of thermodynamics? Be brief.") + +IO.puts("Result: #{inspect(result)}") +IO.puts("Turns: #{length(loom.turns)}") +LoomViz.table(loom, name: "1. Conversation Medium") +``` + +## 2. Code Medium — The Core Insight + +Now the interesting part. In a **code circle**, the entity writes Elixir +that runs on the BEAM. Variables persist across turns. Gates are anonymous +functions in the sandbox. The entity builds up state the way you would in +IEx — except the notebook writes itself. + +Because code is compositional, the entity can compose actions nobody +enumerated in advance. That's the point. + +```elixir +{:ok, cantrip} = + new_cantrip.( + identity: %{ + system_prompt: """ + You are a data analyst working in an Elixir sandbox. + You have these host functions available as anonymous functions (use dot-call syntax): + - done.(answer) — return your final answer and terminate + + Write Elixir code.

Primitives: LLMs, gates, circles (Examples 01–05) -- *Intent*: prove that the spec's baselines (an LLM query and a gate execution) stand alone. Example 01 is the raw `llm` contract — a message array in, a completion out. Example 02 highlights how gates are just typed functions with metadata (`name`, `params`). -- *Circle enforcement*: Example 03 maps directly to `CIRCLE-1` (must expose `done`) and `CIRCLE-2` (must have at least one ward). Example 05 shows how wards merge into a `ResolvedWard`, emphasizing that most restrictive numeric values win, while boolean controls such as `require_done_tool` OR together. -- *Productionization*: treat each gate like a regular service function — unit tests can call `gate.execute` without an LLM. Enforce circle invariants during configuration loading so a malformed circle never reaches runtime. Surface resolved wards in telemetry so operators know what limits apply per cast. - -### 2. Provider-agnostic LLMs (Example 06) -- *Intent*: follow the spec's language-neutrality by modeling the LLM as a pluggable provider. The cantrip script (identity + circle) does not change when swapping Anthropic ↔ OpenAI ↔ Gemini. -- *Productionization*: define LLMs in configuration (`llm: "openai/gpt-5-mini"`) so deployments can swap providers at runtime. Maintain a validation step that checks API keys and limits before casting. - -### 3. Medium physics (Examples 07–09) -- *Conversation default*: Example 07 shows that omitting a medium yields the conversation baseline — the entity "sees" gates as tool calls. This is the spec's default `medium: conversation`. -- *Code mediums*: Example 08 replaces conversation with the JS medium. Instead of textual tool calls, the LLM writes JavaScript inside QuickJS. Example 09 switches to the browser medium (Taiko). Both reinforce the spec rule: **exactly one medium per circle**; whichever medium you choose defines how the circle injects capability docs via the `tool_view()` pattern. -- *Productionization*: document each medium's physics (e.g., JS globals, `submit_answer`, Taiko APIs). Provide teardown hooks (`circle.dispose`) so headless browsers and runtimes close cleanly. When deploying, pin mediums to isolated sandboxes (QuickJS, containerized Chrome) and feed the resulting capability string into audit logs. - -### 4. Delegation and tree memory (Examples 10 & 14) -- *Parallelism*: Example 10 introduces `call_entity_batch`, letting a parent entity spawn multiple child entities with independent contexts. The shared `Loom` captures every turn and gate call, aligning with the spec's requirement that a cast is observable end-to-end. -- *Recursion*: Example 14 narrows to single-child delegation via `call_entity`, enforcing `max_depth` through wards. The parent passes context into child circles, and the loom records the recursion tree. -- *Productionization*: instrument every delegated child with the parent `cantrip_id` and `parent_id` so auditors can replay the tree. Cap recursion using resolved wards, and surface the current `depth` in prompts so LLMs know when they're near the limit. Provide replay tooling that reads the loom and replays turns for debugging. - -### 5. Memory pressure management (Example 11) -- *Intent*: threads that exceed the context window must fold. Example 11 demonstrates `shouldFold` and `partitionForFolding` without calling an LLM, emphasizing that folding is an environment policy, not a model behavior. -- *Productionization*: configure folding thresholds (`DEFAULT_FOLDING_CONFIG`) per deployment, and emit a loom event when folding occurs. When folding is triggered, call back into an LLM to summarize the `toFold` segment and append the summary as a new turn with `metadata.folded_from`. - -### 6. Operational loops (Examples 12–16) -- *Full agent (12)*: combine the JS medium with filesystem gates (`safeFsGates`). The entity runs code inside QuickJS and interacts with the host filesystem only via typed gates; wards (`max_turns`) protect the loop. This is the canonical code-agent deployment. -- *ACP adapter (13 & 15)*: `serveCantripACP` wraps a cantrip in the Agent Control Protocol so editors (VS Code, etc.) can attach. Example 15 extends this with browser automation (`jsBrowserMedium`), recursive delegation, and sliding-window memory, showing how to wire progress callbacks (`progressBinding`) back into ACP clients. -- *Familiar (16)*: a long-lived coordinator entity living inside a JS medium. It cannot touch bash or the browser directly; instead, it creates new cantrips using `cantripGates` and `cast`, handing each child its own medium. Repo observation gates (`repo_files`, `repo_read`, …) give it read-only situational awareness, while `JsonlStorage` keeps the loom persistent so the entity remembers past work. This is the spec's "entity that writes cantrips" pattern: recursion expressed as constructing new circles, not just calling `call_entity`. -- *Productionization*: isolate each medium in its own sandbox (`SandboxContext`, browser contexts, etc.) and use dependency overrides (`getSandboxContext`, `getBrowserContext`) to thread handles through. Persist the loom (`JsonlStorage`) when you need continuity across sessions; otherwise, `MemoryStorage` keeps casts ephemeral. Provide REPL and single-shot modes so the same deployment can run interactively (`runRepl`) or as a service. - -## Operational Checklist - -1. **Define primitives**: implement the LLM interface once, define gates with metadata, and enforce `done` + wards on every circle before casting. -2. **Select medium per circle**: conversation for tool-calling chat, JS for sandboxed code, browser for Taiko automation, bash for shell, etc. Remember: one circle → one medium. -3. **Bind wards + observability**: resolve wards into quantitative limits, publish them to telemetry, and stream every turn into a loom for auditing. -4. **Layer delegation**: add `call_entity`/`call_entity_batch` gates only when recursion or parallelism is required, and cap depth via wards to stay within `REC-DEPTH` constraints. -5. **Attach interfaces**: expose cantrips via ACP or in-process REPLs. Ensure teardown hooks dispose mediums and contexts so casts do not leak resources. -6. **Persist when needed**: use folding + persistent loom storage for long-lived entities (Familiar) so they can resume with bounded context windows. - -Following this progression keeps the examples aligned with the spec: every deployment is just a recombination of the same eleven nouns, wired to the environment you need to operate in. diff --git a/py/README.md b/py/README.md deleted file mode 100644 index 9ea7220b..00000000 --- a/py/README.md +++ /dev/null @@ -1,306 +0,0 @@ -# cantrip — Python - -> Python realization.

Example 07 shows error steering in a code sandbox. -- **In-process Python sandbox.** The entity writes Python that runs via `exec()` with injected host functions. This is the most natural code medium if you're building in Python — the entity writes the same language as the host. -- **Clean API surface.** `Cantrip`, `Identity`, `Circle` — three classes, frozen dataclasses, no framework magic. The public API is 18 symbols. -- **SQLite loom storage.** The only implementation with SQLite as a loom backend (vs JSONL or in-memory). Good for persistent entities that need durable turn history. -- **Protocol adapters.** ACP (stdio), HTTP, and CLI adapters are all included and tested. - -**Limitations:** - -- **One LLM provider.** `OpenAICompatLLM` only — works with OpenAI, OpenRouter, and any OpenAI-compatible endpoint, but no native Anthropic or Google adapters. (The TS implementation has five providers.) -- **Two mediums.** Conversation and code (plus browser with optional Playwright). No bash, VM, or other substrate mediums. -- **In-process isolation only.** The default `InProcessPythonExecutor` uses `exec()` — no security boundary. `SubprocessPythonExecutor` is available but can't share gate functions across the process boundary. Neither is as isolated as QuickJS or node:vm. -- **`MiniCodeExecutor` is vestigial.** A minimal JS interpreter in Python, exported and tested but unlikely to be useful outside of cross-language test compatibility. - ---- - -## Spec Conformance - -Tests: **227 pass, 2 skip** (`uv run pytest tests/ -q`) - -The test suite includes: -- Core lifecycle tests (entity, cantrip, circle, loom) -- Medium behavior tests (tool and code) -- End-to-end delegation tests -- Grimoire example tests (all 12 patterns) -- Spec MUST-rule coverage test (regex scan of SPEC.md rules vs implementation) -- Protocol adapter tests (ACP, HTTP, CLI) - ---- - -## Setup - -Requires Python 3.11+. - -```bash -pip install -e . # or: uv pip install -e . -cp .env.example .env -``` - -Dependencies: `requests`, `PyYAML`, `agent-client-protocol`.

The richest surface for mediums, examples, and the full API. - -This is the TypeScript realization of the cantrip spec. It was the original experimental playground — built up iteratively, then backported to the spec's domain model after SPEC.md was written. It has the most mediums, the most examples, and the most complete coverage of the spec's behavioral rules. If you want to understand how cantrip works by reading code, start here. - -For the full vocabulary and behavioral rules, see [SPEC.md](../SPEC.md) at the repo root. - ---- - -## Quick Start - -```bash -cd ts -bun install -cp .env.example .env # add your API key -``` - -Run the simplest meaningful example — a cantrip with an LLM, an identity, a circle, and an intent: - -```bash -bun run examples/04_cantrip.ts -``` - -Once the vocabulary clicks, try the capstone — a persistent entity that constructs and casts child cantrips from code: - -```bash -bun run examples/16_familiar.ts -``` - ---- - -## Minimal Example - -An LLM, a circle with gates and wards, and an identity — assembled into a cantrip and cast on an intent. - -```typescript -import { cantrip, Circle, ChatAnthropic, done, max_turns, gate } from "cantrip"; - -// LLM — a language model provider -const llm = new ChatAnthropic({ model: "claude-sonnet-4-5" }); - -// A gate — a function the entity can call -const add = gate("Add two numbers", async ({ a, b }: { a: number; b: number }) => a + b, { - name: "add", - params: { a: "number", b: "number" }, -}); - -// Circle — gates + wards (constraints) -const circle = Circle({ - gates: [add, done], - wards: [max_turns(10)], -}); - -// Cantrip — llm + identity + circle -const spell = cantrip({ - llm, - identity: "You are a calculator. Use the add tool, then call done with the result.", - circle, -}); - -// Cast it on an intent -const result = await spell.cast("What is 2 + 3?"); -console.log(result); // "5" -``` - -Each `cast` creates a fresh entity — the cantrip is a reusable script. No medium specified here: the circle uses **conversation** by default, where gates appear as tool calls in natural language. Add a medium to upgrade the entity's action space. - ---- - -## Core Concepts - -### LLM (Cognition) - -An LLM wraps a language model provider. It takes messages and tools, returns a response. Stateless — each query is independent. - -```typescript -import { ChatAnthropic } from "cantrip"; - -const llm = new ChatAnthropic({ model: "claude-sonnet-4-5" }); -const result = await llm.query([ - { role: "user", content: "What is 2 + 2? Reply with just the number." }, -]); -console.log(result.content); // "4" -``` - -Multiple providers: `ChatAnthropic`, `ChatOpenAI`, `ChatGoogle`, `ChatOpenRouter`, `ChatLMStudio`. - -### Identity (Invocation) - -The identity shapes the entity's behavior — a system prompt plus any hyperparameters. It can be a string or an object: - -```typescript -// String shorthand -cantrip({ llm, identity: "You analyze code for bugs.", circle }); - -// Object form -cantrip({ - llm, - identity: { system_prompt: "You analyze code for bugs." }, - circle, -}); -``` - -Gate definitions are automatically derived from the circle — you don't wire them manually. - -### Circle (Control) - -A circle is the entity's capability envelope: **medium + gates + wards**. - -```typescript -import { Circle, done, max_turns, require_done } from "cantrip"; - -const circle = Circle({ - gates: [done], - wards: [max_turns(10)], -}); -``` - -Every circle must have a `done` gate (how the entity signals completion) and at least one ward (how the host prevents infinite loops). This is enforced at construction time. - -**Gates** are functions bound into the circle from outside. The entity calls them as tools: -- `done` — signals task completion via `submit_answer(result)` -- Custom gates — any function you define with `gate()` -- Builtin sets — `safeFsGates` (filesystem), `repoGates` (repo observation), `cantripGates` (child cantrip construction) - -**Wards** are constraints on the loop: -- `max_turns(n)` — limit loop iterations -- `require_done()` — only explicit `done` terminates (text-only responses don't stop the loop) - -### Entity (Emergence) - -An entity is what arises when you cast a cantrip on an intent. You don't build it — it emerges from the loop. It accumulates context, develops strategies, and adapts turn by turn. - -Two ways to create one: - -```typescript -// Cast — one-shot. Entity runs, returns result, disposes. -const result = await spell.cast("Analyze this data"); - -// Summon — persistent. Entity survives, accepts more intents. -const entity = spell.summon(); -const r1 = await entity.send("First task"); -const r2 = await entity.send("Follow-up task"); // remembers r1 -``` - -For interactive sessions, use `summon()` with the built-in REPL: - -```typescript -import { runRepl } from "cantrip"; - -const entity = spell.summon(); -await runRepl({ - entity, - greeting: "Agent ready. Ctrl+C to exit.", -}); -``` - ---- - -## Mediums - -A **medium** is the substrate the entity works in. When no medium is specified, the circle uses **conversation** — the baseline where gates appear as tool calls in natural language. Add a medium to upgrade the entity's action space. - -One medium per circle. The medium replaces conversation — it doesn't sit alongside it. The entity works *in* the medium, not through it. - -### Conversation (default) - -No medium specified. The entity communicates in natural language and uses gates as tool calls. This is how most chat-based agents work. - -```typescript -const circle = Circle({ - gates: [...safeFsGates, done], - wards: [max_turns(100)], -}); -``` - -### VM (node:vm sandbox) - -The entity writes and runs JavaScript in a node:vm context. Full ES2024 — arrow functions, async/await, destructuring. Zero external dependencies. Gates are projected as async functions the entity calls with `await`. - -```typescript -import { vm } from "cantrip"; - -const circle = Circle({ - medium: vm({ state: { context: { items: [1, 2, 3] } } }), - wards: [max_turns(20), require_done()], -}); -``` - -The entity sees a `context` variable in its sandbox and explores it with code. `var` and `globalThis` persist across turns. Weak isolation (V8 context, not a security boundary). - -### JavaScript (QuickJS sandbox) - -The entity works in a QuickJS WASM sandbox. Strong isolation but limited ES version and a serialization boundary — gate results are strings, not native objects. - -```typescript -import { js } from "cantrip"; - -const circle = Circle({ - medium: js({ state: { context: { items: [1, 2, 3] } } }), - wards: [max_turns(20), require_done()], -}); -``` - -### Bash - -The entity writes shell commands. Full access to CLI tools — git, curl, ffmpeg, jq, whatever's installed. - -```typescript -import { bash } from "cantrip"; - -const circle = Circle({ - medium: bash({ cwd: "/project" }), - wards: [max_turns(10)], -}); -``` - -### Browser (Taiko) - -The entity controls a headless browser by writing Taiko code — navigation, clicking, data extraction. - -```typescript -import { browser } from "cantrip"; - -const circle = Circle({ - medium: browser({ headless: true, profile: "full" }), - wards: [max_turns(50), require_done()], -}); -``` - -### jsBrowser - -JS sandbox with browser automation combined — the entity writes JavaScript that can also control a browser. - -```typescript -import { jsBrowser, BrowserContext } from "cantrip"; - -const browserCtx = await BrowserContext.create({ headless: true, profile: "full" }); -const circle = Circle({ - medium: jsBrowser({ browserContext: browserCtx }), - wards: [max_turns(200), require_done()], -}); -``` - -### Other mediums - -Any interactive environment can become a medium — Python, SQL, Frida, GDB, Redis, or a custom DSL. The interface is the same: the entity writes, the medium executes, the result feeds back. - ---- - -## Patterns - -### One-shot cast - -The simplest pattern. Create a cantrip, cast it, get a result. - -```typescript -import { cantrip, Circle, ChatAnthropic, js, max_turns, require_done } from "cantrip"; - -const spell = cantrip({ - llm: new ChatAnthropic({ model: "claude-sonnet-4-5" }), - identity: "Explore the context variable. Use submit_answer() when you have a final answer.", - circle: Circle({ - medium: js({ state: { context: { items: ["alpha", "beta", "gamma"] } } }), - wards: [max_turns(20), require_done()], - }), -}); - -const answer = await spell.cast("Which item comes first alphabetically?"); -``` - -### Persistent REPL - -For interactive sessions — the entity remembers across intents. - -```typescript -import { runRepl, safeFsGates, getSandboxContext, SandboxContext } from "cantrip"; - -const fsCtx = await SandboxContext.create(); - -const entity = cantrip({ - llm, - identity: `Coding assistant. Working dir: ${fsCtx.working_dir}`, - circle: Circle({ - gates: [...safeFsGates, done], - wards: [max_turns(100)], - }), - dependency_overrides: new Map([[getSandboxContext, () => fsCtx]]), -}).summon(); - -await runRepl({ entity, greeting: "Agent ready." }); -``` - -### Recursive delegation - -A parent entity in a JS medium delegates subtasks to children via `call_entity`. - -```typescript -import { call_entity_gate, Loom, MemoryStorage, js } from "cantrip"; - -const entityGate = call_entity_gate({ max_depth: 2, depth: 0, parent_context: data }); - -const circle = Circle({ - medium: js({ state: { context: data } }), - gates: entityGate ? [entityGate] : [], - wards: [max_turns(20), require_done()], -}); - -const loom = new Loom(new MemoryStorage()); -const spell = cantrip({ llm, identity: "Delegate analysis to child entities.", circle, loom }); -const answer = await spell.cast("Analyze each category and summarize the trend."); -``` - -Children get independent circles. `call_entity` is synchronous from the parent's perspective — the parent blocks while the child runs and receives the result as a return value. The shared loom captures parent + child turns as a tree. - -### The Familiar - -The capstone pattern: a long-running entity in a `vm()` medium that creates and casts child cantrips from code. It observes the repo, delegates to specialized children (bash, browser, JS), and synthesizes results. - -```typescript -import { - cantripGates, repoGates, RepoContext, Loom, JsonlStorage, done, - vm, js, bash, browser, getRepoContextDepends, -} from "cantrip"; - -const loom = new Loom(new JsonlStorage(".cantrip/loom.jsonl")); -await loom.load(); - -const cantripConfig = { - mediums: { - bash: (opts) => bash({ cwd: opts?.cwd ?? repoRoot }), - js: (opts) => js({ state: opts?.state }), - vm: (opts) => vm({ state: opts?.state }), - browser: () => browser({ headless: true, profile: "full" }), - }, - gates: { done: [done] }, - default_wards: [{ max_turns: 15 }], - loom, -}; - -const { gates: cGates, overrides: cOverrides } = cantripGates(cantripConfig); -const repoCtx = new RepoContext(repoRoot); - -const circle = Circle({ - medium: vm(), - gates: [...repoGates, ...cGates], - wards: [max_turns(50), require_done()], -}); - -const spell = cantrip({ - llm, - identity: SYSTEM_PROMPT, - circle, - dependency_overrides: new Map([ - [getRepoContextDepends, () => repoCtx], - ...cOverrides, - ]), - loom, - folding_enabled: true, -}); -``` - -Inside the Familiar's vm medium, the entity writes modern JS to coordinate: - -```javascript -// Shell work — child runs in bash -const worker = cantrip({ - llm: "anthropic/claude-haiku-4.5", - identity: "Execute the command and report output.", - circle: { medium: "bash", gates: ["done"], wards: [{ max_turns: 5 }] } -}); -const output = await cast(worker, "Run the test suite"); - -// Thinking — leaf cantrip, single LLM call -const thinker = cantrip({ llm: "anthropic/claude-haiku-4.5", identity: "Analyze code." }); -const analysis = await cast(thinker, "What bugs do you see?\n" + code); - -// Compose in code — loops, conditionals, pipelines -const files = JSON.parse(await repo_files("src/**/*.ts")); -for (const file of files) { - const src = await repo_read(file); - if (src.includes("TODO")) { - const review = await cast( - cantrip({ llm: "anthropic/claude-haiku-4.5", identity: "Find TODOs." }), - src - ); - console.log(file + ": " + review); - } -} -``` - -See `examples/16_familiar.ts` for the full implementation. - ---- - -## The Loom - -Every turn is recorded in a **loom** — a structured log that captures the entity's full execution history as a tree of turns. - -```typescript -import { Loom, JsonlStorage, MemoryStorage } from "cantrip"; - -// In-memory (ephemeral) -const loom = new Loom(new MemoryStorage()); - -// Persistent to disk -const loom = new Loom(new JsonlStorage(".cantrip/loom.jsonl")); -await loom.load(); -``` - -The loom records whether each thread **terminated** (entity called `done`) or was **truncated** (ward triggered). This distinction matters: terminated threads are complete episodes, truncated threads are interrupted ones. - -**Folding** compresses old turns to keep the entity's context window manageable while preserving key information. It reads from the loom and writes compressed summaries back into the entity's working state. - ---- - -## Examples - -The `examples/` directory walks through the concepts in order. Each example builds on the previous ones — the progression is the curriculum. - -| # | Example | What it teaches | -|---|---------|----------------| -| 01 | `llm` | LLM as stateless query | -| 02 | `gate` | Defining callable functions | -| 03 | `circle` | Gates + wards + validation | -| 04 | `cantrip` | LLM + identity + circle = script | -| 05 | `ward` | Constraints and safety limits | -| 06 | `providers` | Multi-provider LLMs | -| 07 | `conversation` | Conversation medium (default) | -| 08 | `js_medium` | QuickJS sandbox | -| 09 | `browser_medium` | Taiko browser automation | -| 10 | `composition` | Parallel delegation via call_entity_batch | -| 11 | `folding` | Context compression | -| 12 | `full_agent` | JS medium + filesystem gates | -| 13 | `acp` | Agent Client Protocol adapter | -| 14 | `recursive` | Depth-limited recursive entities | -| 15 | `research_entity` | jsBrowser + recursion + ACP | -| 16 | `familiar` | Cantrip construction as medium physics | -| 17 | `leaf_cantrip` | Simplest delegation — llm + identity, one LLM call | -| 18 | `vm_medium` | node:vm sandbox — full ES2024, async/await | -| 19 | `bash_medium` | Entity works IN bash as primary medium | -| 20 | `data_exploration` | RLM pattern — data in sandbox, explore with code | -| 21 | `independent_axes` | M, G, W as orthogonal knobs | - -Run any example: -```bash -bun run examples/04_cantrip.ts -``` - ---- - -## What You Can Learn Here - -This is the reference implementation — the most complete realization of the spec. It has things the other implementations don't: - -- **Five mediums** (conversation, VM, QuickJS, bash, browser) — see the spec's medium concept expressed in multiple substrates -- **21 examples** — the fullest progression from raw LLM query to familiar -- **Dependency injection via `Depends`** — a pattern for wiring gate dependencies without coupling -- **Ephemeral gate tuning** — mark gate results as ephemeral to save context space -- **The gate decorator API** — both high-level (`gate()`) and low-level (`rawGate()`) interfaces - -It is also the least portable. It depends on Bun, QuickJS WASM bindings, Taiko, and node:vm. If you want a cleaner starting point for your own implementation, the Python or Elixir versions may be easier to read and adapt. - ---- - -## Spec Conformance - -Tests: **615 pass, 55 skip** (`bun test --timeout 30000`) - -The skipped tests are primarily integration tests that require API keys or specific runtime conditions. Core behavioral rules are fully covered. - -Provider support: Anthropic, OpenAI, Google, OpenRouter, LMStudio — the broadest of the four implementations. - ---- - -## Setup - -```bash -bun install -cp .env.example .env -# Edit .env with your API key(s) -``` - -Set at least one provider: -```bash -ANTHROPIC_API_KEY="sk-..." -# or -OPENAI_API_KEY="sk-..." -# or -OPENROUTER_API_KEY="sk-..." -``` - -Run the test suite: -```bash -bun test --timeout 30000 -``` - ---- - -## License - -MIT diff --git a/ts/SPEC.md b/ts/SPEC.md deleted file mode 120000 index 269bfc79..00000000 --- a/ts/SPEC.md +++ /dev/null @@ -1 +0,0 @@ -../SPEC.md \ No newline at end of file diff --git a/ts/TESTING.md b/ts/TESTING.md deleted file mode 100644 index af47780b..00000000 --- a/ts/TESTING.md +++ /dev/null @@ -1,164 +0,0 @@ -# Testing - -## Running Tests - -```bash -bun test -``` - -This runs unit tests (offline, mocked), spec tests (behavioral rules from SPEC.md), and integration tests (live API calls).
