From e96c4db163a44b7f8cec055ee18f39cc357b4b46 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 13 May 2026 21:38:12 +0000 Subject: [PATCH 01/17] feat(ORCH): add idea + research spec for orchestrator-first plugin (#501) Resolves all 7 open decisions and 5 open questions from issue #501. Establishes the orchestrator-first architecture vision: the orchestrator becomes the dispatch authority (not advisory-only), packaged as a proper Claude Code plugin via settings.json + .claude-plugin/plugin.json. Research synthesis covers: Claude plugin architecture constraints, Anthropic native Orchestrator-Subagent pattern recommendation (over LangGraph/CrewAI), competitive landscape (Devin, Copilot Workspace, Cursor, BMAD, Kiro, GitHub Spec Kit), and full Specorator codebase audit (36 agents, 38 skills, 85 commands, 12 plugin groups).

The orchestrator agent exists but is **advisory-only** — it has Read/Grep tools only, cannot dispatch agents, cannot update workflow state, and cannot enforce stage gates. This means Specorator has all the right building blocks (36 agents, 38 skills, 85 commands, 12 plugin groups) but no single authority that drives a feature from problem statement to shipped solution without constant user hand-holding. The Specorator Claude plugin exists (distributed via `dist/claude-plugin` per ADR-0043) but does not make the orchestrator the primary entry point: installing the plugin gives users the full command palette, not a guided delivery loop. The result is high onboarding friction — a new user must read significant documentation before getting a usable result, while competitors like Cursor, Copilot Workspace, and GitHub Spec Kit deliver value in under five minutes. + +## Proposed architecture + +The **orchestrator becomes the dispatch authority** — not just an advisor. When a user enables the Specorator plugin, Claude Code loads the orchestrator as the main session agent (`settings.json agent: orchestrator`).

It is not a parallel track alongside the existing 11-stage lifecycle; it IS the lifecycle, collapsed into a single orchestrated session for issue-resolution use cases. The existing `/spec:*` stage commands become the building blocks the orchestrator invokes, not the primary user interface. + +The project's plugin packaging is simultaneously refactored to be a **proper Claude Code plugin** with `.claude-plugin/plugin.json`, reconciling the existing ADR-0036 capability manifests (`plugins/*/manifest.md`) with the Claude Code plugin format. + +## Architecture diagram + +``` +User submits problem statement + │ + ▼ +┌────────────────────────┐ +│ Orchestrator │ ← Main session agent (settings.json: agent: orchestrator) +│ Scope phase │ grill skill: structured intake → EARS acceptance criteria +│ │ AskUserQuestion gate — confirm scope before research +└──────────┬─────────────┘ + │ + ▼ +┌────────────────────────┐ +│ Research wave │ ← N parallel Researcher subagents (analyst agent class) +│ (parallel) │ Each: bounded question + clean context + worktree isolation +│ │ Orchestrator synthesises results, removes duplication +└──────────┬─────────────┘ + │ + ▼ +┌────────────────────────┐ +│ Design synthesis │ ← Orchestrator + architect subagent +│ │ Produces design.md +│ │ AskUserQuestion gate — user approves / rejects / edits +└──────────┬─────────────┘ + │ (approved) + ▼ +┌────────────────────────┐ +│ Plan phase │ ← Planner subagent decomposes design into task DAG +│ │ tasks.md with explicit dependency edges +│ │ Wave schedule = topological sort (Kahn BFS) +└──────────┬─────────────┘ + │ + ▼ +┌────────────────────────┐ +│ Implement waves │ ← Orchestrator dispatches dev/qa subagents per wave +│ (parallel within │ isolation: worktree per agent +│ each wave) │ Stall detection: counter per wave → escalate to HITL +└──────────┬─────────────┘ + │ + ▼ +┌────────────────────────┐ +│ Review phase │ ← reviewer + qa subagents validate vs acceptance criteria +│ │ AskUserQuestion gate — accept / request specific revision +│ │ Revision re-enters loop at Implement wave +└──────────┬─────────────┘ + │ (accepted) + ▼ +┌────────────────────────┐ +│ Session summary │ ← Orchestrator produces human-readable summary: +│ │ decisions made, evidence used, artifacts produced, +│ │ traceability IDs, open follow-ups +└────────────────────────┘ +``` + +## Target users + +- **Primary:** Senior solo developer or small team (2–10 people) building production features who need structured delivery without the friction of manually chaining 11 slash commands. They accept discipline in exchange for confidence in what they shipped. +- **Secondary:** Agency or service provider doing repeatable client delivery who needs traceable artifacts (ADRs, EARS requirements, traceability.md) to defend decisions and report to stakeholders. +- **Tertiary:** Enterprise evaluator assessing agentic tools against governance requirements (EU AI Act audit trails, ISACA governance standards) — Specorator's ID chain (REQ→T→TEST→review finding) is unique in the market. + +## Desired outcome + +A first-time Specorator user can install the plugin, submit a GitHub issue number or a free-text problem statement, and receive a fully spec-driven, traceable resolution session — complete with requirements, design, implementation, tests, and a session summary — without reading any documentation beyond the welcome message.

The 11-stage lifecycle commands remain as building blocks; no stage is removed. | +| Design review step synchronous or async (PR)? | Synchronous AskUserQuestion (chosen by product owner). Three defined gate points: post-scope, post-design, post-review. | +| How does this compose with `/issue:tackle`? | `/issue:tackle` is subsumed as the "issue-first entry mode" of the orchestrator. The orchestrator detects a GitHub issue reference in the input and uses the issue body as the initial scope context, then runs the full goal-loop. `/issue:tackle` becomes an alias that pre-configures the scope phase. | + +## Constraints + +- **Technical:** Subagents cannot spawn subagents (Claude Code platform hard limit). The orchestrator must be the root session agent, not itself a subagent. All parallelism is orchestrator-to-subagent only. +- **Technical:** Agent teams (experimental) require `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` and have known limitations (skills/MCP not loaded in teammate definitions, no session resumption). MVP uses stable subagent model only. +- **Technical:** Plugin agents cannot declare `hooks`, `mcpServers`, or `permissionMode` in frontmatter — these are stripped for security. Plugin-level hooks and MCP are declared in the plugin manifest. +- **Naming collision:** Specorator's `plugins/*/manifest.md` (ADR-0036 capability contract layer) uses a different format than Claude Code's `.claude-plugin/plugin.json`. These must coexist: `plugins/` stays as the MCP contract layer; `.claude-plugin/` is the new Claude Code plugin entry point. +- **Distribution:** Plugin bundle is gitignored on `develop`/`main` (ADR-0043). Build pipeline CI already handles this. Orchestrator-first architecture must work within that distribution model. +- **Backward compatibility:** All 85 existing slash commands must remain functional. The orchestrator is an accelerator on top of the existing command system, not a replacement. +- **Scope (this feature):** Spec only — no implementation code in this iteration. Implementation tracked in a follow-up feature. + +## Out of scope (preliminary) + +- Agent teams mode (experimental) — tracked as v2 candidate once agent teams stabilize in Claude Code +- LangGraph, CrewAI, or any third-party orchestration framework — adding external dependencies contradicts the "methodology, not a product" positioning +- Async/PR-based approval gates — synchronous gates chosen; async mode is a future extension +- Specorator marketplace entry changes — ADR-0043 distribution model is already correct; no marketplace changes in this feature +- Changes to the 11-stage lifecycle artifact formats — orchestrator invokes existing stages, does not alter them + +## Acceptance criteria (refined) + +- [ ] User can submit a free-text problem statement or GitHub issue reference and receive a complete goal-loop session without reading documentation. +- [ ] Orchestrator correctly gates on user approval at three defined points: post-scope, post-design-approval, post-review. +- [ ] Researcher subagents run in parallel, their outputs are merged without duplication, and the synthesised result is written to `research.md` in the feature's spec folder. +- [ ] Implementer subagents run in topological wave order; agents within the same wave run in parallel in isolated worktrees. +- [ ] Orchestrator detects stalled subagents (no progress within max iteration budget) and escalates to human review rather than looping indefinitely. +- [ ] Session ends with a structured summary: decisions made, EARS acceptance criteria status, artifacts produced, traceability IDs, open follow-ups. +- [ ] All existing `/spec:*` slash commands continue to function as standalone invocations. +- [ ] Specorator plugin has a valid `.claude-plugin/plugin.json` and `settings.json` that make the orchestrator the main session agent on plugin enable. +- [ ] The orchestrator's dispatch authority is exercised via the Agent tool, not via text recommendations — it invokes, not advises. + +## References + +- Issue #501 — [original concept](https://github.com/Luis85/agentic-workflow/issues/501) +- ADR-0036 — Adopt plugin manifests as the Specorator capability contract +- ADR-0043 — Distribute Claude Code plugin bundle from orphan dist branch via git-subdir +- ADR-0026 — Freeze v1 workflow track taxonomy +- Claude Code docs — [plugins reference](https://code.claude.com/docs/en/plugins-reference) +- Claude Code docs — [create custom subagents](https://code.claude.com/docs/en/sub-agents) +- Anthropic Engineering — [How we built our multi-agent research system](https://www.anthropic.com/engineering/multi-agent-research-system) + +--- + +## Quality gate + +- [x] Problem statement is one paragraph and understandable to a non-expert. +- [x] Target users named. +- [x] Desired outcome stated. +- [x] Constraints listed. +- [x] Open questions captured and resolved. +- [x] Scope is bounded — no "boil the ocean" framing. diff --git a/specs/goal-oriented-orchestrator-plugin/research.md b/specs/goal-oriented-orchestrator-plugin/research.md new file mode 100644 index 000000000..dce4fc7fb --- /dev/null +++ b/specs/goal-oriented-orchestrator-plugin/research.md @@ -0,0 +1,279 @@ +--- +id: RESEARCH-ORCH-001 +title: Orchestrator-first Claude plugin — research synthesis +stage: research +feature: goal-oriented-orchestrator-plugin +status: complete +owner: analyst +inputs: + - IDEA-ORCH-001 +created: 2026-05-13 +updated: 2026-05-13 +--- + +# Research — Orchestrator-first Claude plugin + +## Research questions + +| ID | Question | Status | +|---|---|---| +| Q1 | What is the Claude Code plugin format and how does `settings.json agent` work? | answered | +| Q2 | Which multi-agent orchestrator pattern best fits Specorator's bounded issue-resolution loop? | answered | +| Q3 | What do competitors offer and where is the defensible differentiation gap? | answered | +| Q4 | What is the current Specorator architecture inventory and what gaps exist vs. the orchestrator-first vision? | answered | +| Q5 | What are the hard platform constraints that the architecture must work within? | answered | +| Q6 | How does the orchestrator handle human approval gates durably? | answered | +| Q7 | How do parallel subagent write conflicts get resolved in implementation waves? | answered | +| Q8 | What naming collision exists between ADR-0036 `plugins/` and Claude Code's `.claude-plugin/`? | answered | + +--- + +## Market / ecosystem + +### Spec-driven development tool landscape (May 2026) + +The spec-driven development (SDD) category has become contested in under 18 months.

No existing plugin combines spec-driven lifecycle + EARS + traceability + orchestrated execution. + +### User needs — evidence + +- **Trust crisis:** Stack Overflow 2025 survey — AI tool trust at 29%, down from 40% in 2024. Developers are willing but reluctant to trust autonomous agents. *(Stack Overflow 2025 Developer Survey)* +- **Verification gap:** 95% of developers report spending significant time reviewing, testing, and correcting AI output. No current tool provides a deterministic pre-stage verification chain. *(O'Reilly radar 2025)* +- **Context rot:** Experienced developers using AI coding tools were 19% slower in a METR RCT, despite predicting 24% gains. Root cause: context windows fill with failed attempts and debug noise, deprioritising earlier constraints. Specorator's file-based spec artifacts directly address this — agents re-read canonical artifacts rather than relying on conversation history. *(METR RCT, CodeRabbit analysis)* +- **AI-coauthored PRs:** 1.7x more major issues than human-written code (CodeRabbit 2025 analysis). The gap is traceable to absent requirements, missing acceptance criteria, and lack of intermediate verification. +- **Enterprise audit demand:** EU AI Act requirements, ISACA governance concerns, and enterprise risk teams are creating demand for agentic workflows that produce durable, human-readable evidence of their reasoning. No current SDD tool outside Specorator produces this chain. *(Galileo, ISACA)* +- **Onboarding friction:** Most-adopted tools (Cursor, Cline, GSD) succeed because users get a useful result in under 5 minutes. Specorator's current onboarding requires reading documentation before getting value — a confirmed adoption blocker. + +--- + +## Alternatives considered + +### Alternative A — Third-party orchestration framework (LangGraph / CrewAI) + +Adopt LangGraph or CrewAI as the orchestration engine. LangGraph provides directed-graph execution with native checkpoint-and-resume (PostgresSaver/SqliteSaver), structured HITL via `interrupt()` + `Command(resume=...)`, and parallel fan-out with barrier synchronisation. CrewAI provides declarative DAG-driven task execution with `Flows` for deterministic routing. + +**Pros:** +- LangGraph: most mature HITL + durable checkpoint model available; explicit state schema with reducers; large production user base with documented failure modes. +- CrewAI: cleanest declarative DAG-driven execution; natural wave scheduling; manager LLM routing built-in. +- Both: battle-tested in production; not invented here. + +**Cons:** +- LangGraph requires a persistent checkpointer backend (PostgreSQL or Redis) for true durable HITL — operational complexity incompatible with a zero-dependency Claude plugin. +- Python-first; TypeScript support is less mature; Specorator is a Markdown-first, TypeScript-tooled project. +- External framework dependency contradicts the "methodology, not a product" positioning and the tool-agnostic Layer 0 value proposition. +- Adding any third-party framework introduces a version coupling risk in a fast-moving ecosystem. +- CrewAI HITL is less mature than LangGraph — no native durable pause-and-resume across process boundaries. + +**Verdict:** Rejected. The operational cost and positioning risk outweigh the checkpoint sophistication. Specorator's `workflow-state.md` on disk provides durable-enough state for synchronous HITL gates where the human responds in seconds to minutes, not days. + +--- + +### Alternative B — Anthropic native Orchestrator-Subagent pattern (recommended) + +Implement the Anthropic-published Orchestrator-Subagent pattern directly using Claude Code's native Agent tool dispatch, without adopting a third-party orchestration framework. State is managed in `workflow-state.md` (Zod-typed per ADR-0042). HITL gates use `AskUserQuestion` at three defined points. DAG wave scheduling is a topological sort (~100 lines of control flow) in the orchestrator skill. + +**Pros:** +- Zero additional dependencies — Claude Code's Agent tool is the only dispatch mechanism needed. +- Direct alignment with Anthropic's own published patterns. The orchestrator's 90.2% performance improvement in Anthropic's multi-agent research system traces to parallel reasoning across more aggregate context, not to framework magic. +- Each stage specialist already receives only its predecessor artifact — context compression is natural by design. +- `workflow-state.md` written to disk before each `AskUserQuestion` call provides durable-enough state persistence for synchronous HITL. +- No platform lock-in beyond Claude Code itself (which is the target environment by definition). +- Subagent context is clean per spawn — no context rot. + +**Cons:** +- No built-in durable pause-and-resume across process crashes (if the orchestrator process dies between HITL gates, in-flight subagent results from the current wave are lost and must be re-run). +- Stall detection, retry logic, and wave scheduling are hand-rolled rather than framework-provided. Estimated ~200–300 lines of orchestrator control flow. +- No peer-to-peer subagent communication (subagents report to orchestrator only) — complex multi-subagent negotiation patterns are not possible in v1. + +**Verdict:** Recommended. The architectural fit with Specorator's existing model is high; the engineering investment in wave scheduling and stall detection is bounded and implementable; the HITL durability constraint is acceptable for synchronous gates. + +--- + +### Alternative C — Claude Code Agent Teams (experimental) + +Use Claude Code's experimental agent teams feature (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`) to give subagents peer-to-peer communication, a shared task list, and independent context windows. The orchestrator is the lead; specialists are teammates. + +**Pros:** +- Peer-to-peer messaging enables richer coordination between parallel implementers. +- Shared task list allows teammates to mark their own tasks complete without returning to orchestrator. +- Independent context windows prevent any single agent's context from growing unbounded. + +**Cons:** +- Experimental feature, disabled by default — shipping risk for a publicly distributed plugin. +- Known limitations: `skills` and `mcpServers` frontmatter fields are NOT applied when an agent definition runs as a teammate, silently breaking any agent that depends on pre-loaded skills. +- No session resumption for in-process teammates — a crash loses all teammate state. +- Task status can lag; teammates may not mark tasks complete reliably. +- One team at a time per lead — no nested teams. +- Performance: agent teams scale token costs linearly with teammate count. + +**Verdict:** Reserved for v2. Track `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS` status; revisit when teams stabilise. The v1 architecture is designed to be extensible to teams without breaking changes. + +--- + +## Technical considerations + +### Claude Code plugin architecture + +**Plugin format:** A proper Claude Code plugin requires: +- `.claude-plugin/plugin.json` — the Claude Code plugin manifest (name is the only required field; all component paths are relative to the plugin root) +- `settings.json` at the plugin root — declares `agent: "orchestrator"` to make the orchestrator the main session agent when the plugin is enabled +- `agents/orchestrator.md` — the main agent definition (YAML frontmatter + system prompt) +- `agents/`, `skills/`, `commands/` — component directories mirrored from `.claude/` +- `.mcp.json` — MCP server declarations for the plugin + +**Security constraints on plugin agents (hard limits):** +- `hooks`, `mcpServers`, and `permissionMode` frontmatter fields are stripped from plugin agent definitions. Plugin-level hooks and MCP must be declared in the plugin manifest. +- Path traversal (`../`) is blocked after plugin caching — all resources must be within the plugin root. +- Plugin agents inherit the session permission mode; they cannot override it. + +**Subagent execution constraints (hard platform limits):** +- Subagents cannot spawn subagents — the Agent tool is removed from subagent contexts. The orchestrator must be the root session agent (enforced by `settings.json agent: orchestrator`). +- Subagents do not inherit the parent's conversation history — they receive only their spawn prompt. Context compression is enforced by the platform, not optional. +- `isolation: worktree` is the only supported isolation mode for plugin agents. Worktrees are auto-cleaned if the agent makes no changes. + +**Naming collision resolution:** Specorator uses two manifest systems that must coexist: +- `plugins/*/manifest.md` + `plugins/*/schema.json` (ADR-0036): Specorator's internal capability contract layer, used as input to the future MCP Server (issue #316). These remain unchanged — they are the MCP contract layer. +- `.claude-plugin/plugin.json`: the new Claude Code plugin entry point. This is a separate file at the repo root within the `claude-plugin/specorator/` bundle directory, generated by `build-claude-plugin.ts` from canonical sources. The two systems coexist without conflict. + +### Dispatch authority refactor (current gap) + +The current orchestrator agent has only `tools: [Read, Grep]`. To become a dispatch authority, it needs `tools: [Agent, Read, Edit, Write, AskUserQuestion]`: +- `Agent` — to spawn specialist subagents (researcher, architect, planner, dev, qa, reviewer) +- `Read/Write/Edit` — to manage `workflow-state.md` state transitions +- `AskUserQuestion` — to implement HITL gates + +The orchestrator must also own `workflow-state.md` transitions (currently updated by individual commands). This is a breaking change to the command dispatch model: commands become building blocks invoked by the orchestrator, not standalone entry points for state mutation. + +### State management model + +`workflow-state.md` is the durable checkpoint: +- Written to disk before every `AskUserQuestion` call (HITL gate) — ensures state is recoverable if the session crashes during the human decision window +- Typed via Zod schema (ADR-0042 migration path) — enables the orchestrator to validate preconditions before dispatching +- Owned by the orchestrator — only the orchestrator writes stage transitions; specialist subagents write their artifact files but do not modify workflow-state.md + +Living spec principle: specialist subagents receive only the artifact relevant to their task (e.g., planner receives `requirements.md` and `design.md`, not full conversation history). This is the primary mechanism for preventing context rot across a multi-stage session. + +### DAG wave execution + +The task DAG from `tasks.md` is executed in topological waves: +1. Parse `tasks.md` — extract nodes (tasks) and edges (depends_on) +2. Topological sort (Kahn's BFS algorithm) — produces ordered waves +3. Each wave: orchestrator dispatches one subagent per task in the wave (parallel Agent tool calls in a single turn) +4. Collect results — orchestrator validates each result against the task's expected output schema +5. Stall detection — counter per wave; if N consecutive steps produce no progress, orchestrate escalates to HITL +6. Advance to next wave only after all tasks in the current wave pass validation + +Parallel write conflict prevention: `isolation: worktree` per implementer subagent. Each subagent works in its own isolated worktree.

Together they introduce the **goal-loop** — a six-phase conductor skill (Scope → Research → Design → Plan → Implement → Review) that moves a user from a free-text problem statement or GitHub issue reference to a fully traceable, spec-driven resolution session without requiring any manual slash-command chaining. This is built now because Specorator's command-chain-driven onboarding is the confirmed primary adoption blocker — first-time users must read documentation before receiving value — while competitors (GitHub Copilot Workspace, Cursor 2.0, GitHub Spec Kit) deliver a useful result in under five minutes. The orchestrator-first architecture is the minimal change that closes this gap while preserving all 85 existing slash commands and the full 11-stage lifecycle methodology. + +## Goals + +- G1: Enable a first-time user to submit a problem statement or GitHub issue reference and receive a complete, traceable resolution session without reading documentation beyond the welcome message. +- G2: Give the orchestrator full dispatch authority over specialist subagents via the Agent tool, replacing its current advisory-only role. +- G3: Deliver a valid Claude Code plugin package (`.claude-plugin/plugin.json` + `settings.json`) that makes the orchestrator the default session agent on plugin enable. +- G4: Introduce exactly three synchronous human-in-the-loop (HITL) gates — post-scope, post-design, and post-review — giving users meaningful control without excessive interruption. +- G5: Preserve full backward compatibility: all 85 existing slash commands remain functional as standalone invocations. + +## Non-goals + +- NG1: Agent teams mode (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`) — reserved for v2 when the feature stabilises in Claude Code. +- NG2: Third-party orchestration frameworks (LangGraph, CrewAI, or similar) — incompatible with zero-dependency plugin distribution and tool-agnostic positioning. +- NG3: Async or PR-based approval gates — synchronous AskUserQuestion is the chosen pattern for v1. +- NG4: Changes to the 11-stage lifecycle artifact formats (idea.md, research.md, design.md, tasks.md) — the orchestrator invokes existing stages; it does not alter their schemas. +- NG5: Specorator marketplace entry changes — ADR-0043 distribution model is already correct. +- NG6: Implementation code in this iteration — this feature delivers the specification only; implementation is tracked as a follow-up. +- NG7: MCP capability broker or plugin registry runtime loading — planned for Layer 3; out of scope for this feature. + +## Personas / stakeholders + +| Persona | Need | Why it matters | +|---|---|---| +| Senior solo developer (primary) | Submit a GitHub issue or problem statement and receive a spec-driven session without chaining 11 commands | Today's command-chain onboarding blocks adoption; this persona chooses tools by time-to-first-result | +| Small engineering team (2–10 people) | Traceable artifacts (EARS requirements, ADRs, traceability.md) that survive session boundaries and can be reviewed by teammates | File-based artifacts are the primary mechanism for team handoffs; session-only state is not sufficient | +| Agency / service provider (secondary) | Repeatable, auditable delivery records to defend decisions and report progress to clients | Traceability ID chain (REQ→T→TEST→finding) is a differentiator; no current competitor produces this chain | +| Enterprise evaluator (tertiary) | Evidence of governance and audit trails for EU AI Act, ISACA, and internal risk review | Specorator's ID chain is uniquely positioned in the market; this persona triggers procurement decisions | +| Existing Specorator user | All current slash commands continue to work exactly as before | Backward compatibility is non-negotiable; orchestrator is an accelerator, not a constraint | + +## Jobs to be done + +- When I have a GitHub issue number but no time to manually run 11 slash commands, I want to hand it to the orchestrator and receive a fully resolved, traceable result, so I can focus on decisions rather than command logistics. +- When I am scoping a new feature, I want structured EARS acceptance criteria extracted from my description through a guided conversation, so I can trust that downstream agents work from unambiguous goals. +- When I am reviewing a design proposal, I want to see a generated `design.md` artifact and approve or reject it before any implementation begins, so I retain control at the most consequential decision point. +- When I install the Specorator plugin, I want the orchestrator to be my default session agent immediately, so I receive a guided experience without any additional configuration. +- When a subagent stalls and makes no progress, I want to be notified and given control rather than waiting for an infinite loop, so I can redirect or abort without losing the session state accumulated so far. + +## Functional requirements (EARS) + +> All requirements use EARS notation.

Adding `Agent`, `Write`, and `Edit` to its tool list makes that scope explicit and exercisable rather than implicit. + +The platform constraint that subagents cannot spawn subagents (Claude Code hard limit) means the orchestrator must be the root session agent — it cannot itself be invoked as a subagent.

The orchestrator does not perform search operations in the goal-loop; search is delegated to specialist subagents. Removing Grep narrows the tool surface. + +The orchestrator's write boundary is restricted to `specs//` directories and their content files.

Additionally, the platform constraint (subagents cannot spawn subagents) means a subagent cannot be the dispatch authority. This option is architecturally impossible under the platform constraints. + +### Option B — Expand orchestrator tool list (chosen) + +Promote the existing orchestrator to full dispatch authority by adding Agent, Write, Edit, AskUserQuestion. + +- Pros: Consistent with the platform model (root session agent has dispatch authority); no new agent definition; the trust expansion is explicit in the agent frontmatter; the platform constraint enforces that this authority does not cascade to subagents. +- Cons: The orchestrator now has Write access to `specs/` directories; this is a wider trust surface than the current Read-only posture. + +### Option C — Use Agent Teams (experimental) + +Use `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` to delegate dispatch authority to a team lead without expanding the orchestrator's own tool list. + +- Pros: Experimental feature; no tool list change on the orchestrator. +- Cons: Rejected in research.md (Alternative C) as an experimental feature with known limitations: skills and MCP not applied to teammates, no session resumption, one team per lead.

Single file; single source of truth for session state. + +- Pros: consistent with the existing state model; no new infrastructure; session resume reads the same file as phase tracking; the `build-claude-plugin.ts` pipeline requires no changes. +- Cons: `workflow-state.md` grows in size during a goal-loop session.

Directly contradicts NFR-ORCH-008. + +## Consequences + +### Positive + +- Session resume (REQ-ORCH-022) is reliable: all state needed to replay a HITL gate lives in `workflow-state.md`. +- Stall detection (REQ-ORCH-014) is persistent across session restarts: `stall_counters` survive a process restart. +- Pre-flight checks (REQ-ORCH-003) can use `artifacts_produced` to verify preconditions without filesystem stat calls on every field. +- The schema extension is additive — no existing Specorator workflow or test is affected. + +### Negative + +- The Zod schema for `workflow-state.md` (ADR-0042) must be updated before implementation of REQ-ORCH-002 and REQ-ORCH-022 can begin.

Reuse would require both documents to serve two incompatible purposes. + +### Option B — Introduce scope.md and session-summary.md as new artifact types (chosen) + +- Pros: single-responsibility per artifact; clear ownership (orchestrator writes, user reads/edits scope.md; orchestrator writes session-summary.md as a terminal artifact); no schema conflicts with existing stage artifacts; templates enable future human authoring outside the goal-loop. +- Cons: two new artifact types added to the `specs//` space; `docs/sink.md` must be updated. + +### Option C — Store scope criteria only in workflow-state.md (no scope.md) + +- Pros: one fewer artifact file. +- Cons: scope criteria are user-editable (Gate 1 "Edit" path); embedding editable content in `workflow-state.md` — which the user is told not to edit manually — creates a contradiction.

The orchestrator agent exists today but is advisory-only — it cannot dispatch subagents, cannot update workflow state, and cannot enforce stage gates. This design promotes the orchestrator to full dispatch authority and introduces the goal-loop: a six-phase conductor that moves a user from a free-text problem statement or GitHub issue reference to a fully traceable, spec-driven resolution without any manual slash-command chaining. + +The surface this design covers is a **conversational CLI tool** (Claude Code), not a visual application. Every "screen" is a turn in a chat conversation. UX here means: what the orchestrator says, when it says it, what options it offers, and how it recovers from failure. The medium is text; the interaction primitives are `AskUserQuestion` calls and orchestrator status messages. + +## Goals (design-level) + +- DG1: A first-time user who can describe their problem in plain English (or paste a GitHub issue number) should reach a confirmed, structured scope — with EARS acceptance criteria they have approved — within one conversation turn plus one explicit confirmation, without reading any documentation. +- DG2: Every HITL gate must present options that are skimmable in under 10 seconds; the user must never need to hold the full session context in their head to make a good decision at a gate. +- DG3: Every error or stall state must name the affected artifact or task, explain what went wrong in one sentence, and offer at least one forward path. "Something went wrong" is not a valid error message. +- DG4: A user who interrupted a session at any HITL gate must be able to resume from exactly that gate without re-running prior phases. +- DG5: All existing `/spec:*` slash commands remain discoverable and usable unchanged. The orchestrator is an accelerator, not a cage. + +## Non-goals + +- This design does not define visual styling, colours, or font choices.

All artifacts land in the existing `specs//` convention. The orchestrator is the single entry point; the six goal-loop phases are not separately addressable by the user — they are internal orchestrator states. + +**Deep-link convention:** There is no URL-based deep-linking in a CLI context. Session resume is file-based: `workflow-state.md` is the bookmark. A user can direct-link to a specific gate by resuming a session; the orchestrator reads the saved state and replays the gate. + +**Feature slug derivation:** The orchestrator derives the feature slug from the first noun phrase of the problem statement or from the GitHub issue number (e.g., `issue-501`). The user sees the slug in the Gate 1 confirmation message. If the slug conflicts with an existing `specs/` folder, the orchestrator appends a short hash suffix and notes this in the Gate 1 message. + +**Artifact reachability map:** + +| Artifact | Phase produced | Reachable by user | +|---|---|---| +| `specs//scope.md` | Scope | Edit directly; orchestrator re-reads after user edits | +| `specs//research.md` | Research wave | Read-only during session; inspect at any time | +| `specs//design.md` | Design synthesis | Edit directly at Gate 2; orchestrator re-reads | +| `specs//tasks.md` | Plan | Read-only during session | +| `specs//session-summary.md` | Review (on accept) | Read-only; the primary handoff artifact | +| `specs//workflow-state.md` | All phases (orchestrator-owned) | Read only; do not edit manually during a session | + +--- + +### HITL gate designs + +All gate prompts follow a consistent structure: + +1. **One-line context anchor** — names the feature slug and current phase so the user knows where they are. +2. **Structured content block** — the information the user must evaluate (criteria list, design summary, or verdict table). +3. **Explicit options** — each option has a label and a one-sentence description of what happens next. +4. **Escape hatch** — every gate offers an abort or abandon path so the user never feels trapped. + +--- + +#### Gate 1 — Scope confirmation (REQ-ORCH-008) + +Presented after the grill skill completes EARS extraction. The user must be able to evaluate this in under 10 seconds for a well-scoped problem (≤5 criteria). + +**Trigger:** grill skill returns structured criteria.

Status message confirms: "Scope approved. Starting research wave." | +| E | Edit | Orchestrator outputs the file path to `specs//scope.md` and waits. On "done", orchestrator re-reads the file, re-extracts criteria, and re-presents Gate 1. | +| X | Abort | Orchestrator outputs: "Session aborted. scope.md has been written to specs/[slug]/scope.md for reference. No other artifacts were produced." Session ends. | + +**Design rationale:** The criteria are presented as a flat numbered list rather than a rich table to keep the gate skimmable. The edit path is file-based, not in-chat, because in-chat editing of structured data (EARS clauses) has high error rates and breaks the artifact-as-memory model. + +--- + +#### Gate 2 — Design approval (REQ-ORCH-011) + +Presented after the architect subagent produces `design.md`. This is the last affordable correction point before implementation begins. + +**Trigger:** Architect subagent returns; `design.md` is written. Orchestrator writes `workflow-state.md` before displaying. + +**Prompt structure:** + +``` +Goal-loop · [feature-slug] · Design approval + +The architect has produced a design document (specs/[slug]/design.md). +Here is the inline summary — the full document is available at that path. + +DESIGN SUMMARY +────────────── +Architecture decisions: + · [Decision 1 — one sentence] + · [Decision 2 — one sentence] + · [Decision 3 — one sentence] + +Key components: + · [Component 1 — one sentence role] + · [Component 2 — one sentence role] + +Risks flagged: + · [Risk 1 — one sentence] + · [Risk 2 — one sentence] + +What would you like to do? + + A Approve — proceed to planning and implementation. + E Edit — open specs/[slug]/design.md, make changes, reply "done". + R Reject — provide a reason and I will restart the research phase with your feedback. +``` + +**Option definitions:** + +| Label | Option | What happens next | +|---|---|---| +| A | Approve | Orchestrator advances to plan phase. Status: "Design approved. Decomposing into implementation tasks." | +| E | Edit | Orchestrator outputs path to `design.md` and waits. On "done", orchestrator re-reads and re-presents Gate 2 with the updated summary. | +| R | Reject | Orchestrator asks: "Briefly describe what is wrong with this design." User replies with free text. Orchestrator records the rejection reason in `workflow-state.md` and re-enters the research phase with the rejection as additional context. Status: "Returning to research phase with your feedback." | + +**Design rationale:** The summary is rendered in three fixed sections (decisions, components, risks) because these are the three categories a developer needs to validate before approving implementation. Unrestricted summaries would vary in structure and be harder to scan. The reject path explicitly captures a reason to prevent the research phase from reproducing the same design. + +--- + +#### Gate 3 — Review verdict (REQ-ORCH-015) + +Presented after reviewer and QA subagents validate implementation output against the EARS acceptance criteria. + +**Trigger:** All implement waves complete; reviewer + QA subagents return verdict. Orchestrator writes `workflow-state.md` before displaying. + +**Prompt structure:** + +``` +Goal-loop · [feature-slug] · Review verdict + +Implementation is complete. The reviewer has validated each acceptance criterion. + +ACCEPTANCE CRITERIA — REVIEW RESULTS +────────────────────────────────────── +1. [Criterion text] PASS [one-line evidence] +2. [Criterion text] PASS [one-line evidence] +3. [Criterion text] FAIL [one-line explanation of gap] +4. [Criterion text] PASS [one-line evidence] + +Overall: [N] passed, [M] failed. + +What would you like to do? + + A Accept — write session summary and close this goal-loop. + T Targeted revision — specify which criterion to fix; I will re-run only the affected tasks. +``` + +**Option definitions:** + +| Label | Option | What happens next | +|---|---|---| +| A | Accept | Orchestrator produces `session-summary.md`, updates `workflow-state.md` to `complete`, displays artifact list. | +| T | Targeted revision | Orchestrator asks: "Which criterion number(s) need revision, and what should change?" User replies. Orchestrator re-enters implement waves for affected tasks only, with reviewer findings attached as context. | + +**Targeted revision follow-up prompt:** + +``` +Which criterion number(s) should be revised? You can name multiple (e.g., "3" or "2, 3"). +Optionally describe what the correct behaviour should be: +``` + +**Design rationale:** Showing pass/fail per criterion with evidence lets the user make a targeted decision rather than a binary accept/reject. The targeted revision path re-runs only affected tasks to avoid discarding work on passing criteria. All-fail outcomes still offer the accept path — the user may decide partial results are sufficient for their purposes. + +--- + +#### Stall gate — Subagent stall escalation (REQ-ORCH-014) + +Presented when a subagent has completed three consecutive retry iterations without producing progress. + +**Trigger:** Stall counter reaches 3 for a given task. Orchestrator writes `workflow-state.md` (stall noted) before displaying. + +**Prompt structure:** + +``` +Goal-loop · [feature-slug] · Task stalled + +Task [T-ORCH-NNN] in wave [N] has not made progress after 3 attempts. + +TASK DETAILS +──────────── +Task: [task title] +Phase: Implement wave [N] +Retries: 3 + +Last agent output (summarised): + [2–4 sentence summary of what the subagent reported or attempted] + +What would you like to do? + + R Retry — dispatch the agent again for this task. + S Skip — mark this task as deferred and continue with the remaining waves. + Note: tasks that depend on this one will also be deferred. + X Abort session — stop all implementation. A partial session summary will be written + listing completed tasks, deferred tasks, and the reason for stopping. +``` + +**Option definitions:** + +| Label | Option | What happens next | +|---|---|---| +| R | Retry | Orchestrator resets the stall counter for this task and dispatches the subagent again. If stall recurs, gate is presented again. | +| S | Skip | Task and all dependent tasks are marked `deferred` in `workflow-state.md`. Orchestrator continues with remaining independent waves. Deferred tasks appear in `session-summary.md` under "Open follow-ups." | +| X | Abort session | Orchestrator writes partial `session-summary.md` with completed tasks, deferred tasks, and stop reason. `workflow-state.md` is updated to `aborted`. Orchestrator outputs: "Session aborted. Partial session summary written to specs/[slug]/session-summary.md." | + +**Design rationale:** The "Skip" option explicitly names the cascade effect (dependent tasks are also deferred) because a user who does not understand DAG dependencies may skip a foundational task and then wonder why later tasks were not run. Surfacing this in the option description prevents confusion. + +--- + +#### Resume prompt (REQ-ORCH-022) + +Presented when the orchestrator detects an in-progress goal-loop on session start. + +**Prompt structure:** + +``` +Goal-loop · [feature-slug] · Session found + +I found an in-progress goal-loop session for "[feature-slug]". +It was interrupted at: [phase name] (Gate [N] pending your decision). + +Last saved: [timestamp from workflow-state.md] +Artifacts produced so far: [comma-separated list] + +What would you like to do? + + C Continue — resume from Gate [N] with the previously extracted content. + R Restart — discard this session's state and start the scope phase again. + A Abandon — leave the partial artifacts in specs/[slug]/ and start a new session with a different problem. +``` + +**Option definitions:** + +| Label | Option | What happens next | +|---|---|---| +| C | Continue | Orchestrator replays Gate N with its original content from `workflow-state.md`. The user sees the gate as if the session never interrupted. | +| R | Restart | Orchestrator clears the phase state in `workflow-state.md` (preserves artifact files) and re-enters the scope phase. | +| A | Abandon | Orchestrator marks the session abandoned in `workflow-state.md`. Outputs the paths of any artifacts that were written. Accepts a new problem statement immediately. | + +--- + +### Empty / loading / error states + +In a CLI conversational context, "empty", "loading", and "error" states are inline orchestrator messages — not visual components. Each state must name what is happening, why it matters to the user, and what the user can do. + +--- + +#### Empty states + +**No problem statement detected (on session open)** + +Shown when the user's opening message is not recognisable as a problem statement, slash command, or issue reference. + +``` +Welcome to Specorator. + +To start a goal-loop session, describe your problem or paste a GitHub issue reference. + + Examples: + "Add rate limiting to the API gateway" + "#501" + "https://github.com/org/repo/issues/501" + +Or use any /spec:* command directly if you prefer manual control. +``` + +**No in-progress session detected (on attempted resume)** + +Shown when the user types "resume" or similar but there is no `workflow-state.md` with an in-progress goal-loop. + +``` +No in-progress goal-loop session found for this repository. + +To start a new session, describe your problem or paste a GitHub issue reference. +``` + +**Research wave returns no findings** + +Shown after the research wave if all analyst subagents return empty or unusable output. + +``` +Goal-loop · [feature-slug] · Research returned no findings + +The research wave completed but produced no usable findings.

Artifact files in specs/[slug]/ will remain. +``` + +--- + +### Accessibility considerations + +In a CLI conversational context, accessibility means: language clarity, progressive disclosure, discoverability of options, and recovery paths. The WCAG visual conformance model does not apply here; the principles behind it do. + +**Language clarity** + +- All orchestrator messages use plain English at a reading level accessible to a mid-career developer unfamiliar with Specorator's terminology. +- EARS notation is not explained at every gate. Gate 1 presents criteria as a numbered list without labelling them "EARS criteria" — a user does not need to know the term to evaluate whether the list captures their intent. +- Jargon in error messages is avoided. "The architect subagent" is written as "the design document generator" in error copy where the subagent identity is irrelevant to the recovery action. +- All technical terms that a user must act on (file paths, task IDs) are presented on their own line, not embedded in a sentence, so they are easy to copy. + +**Option discoverability** + +- Every `AskUserQuestion` gate lists all available options explicitly. There are no hidden commands. +- Option labels use single uppercase letters (A, E, R, X, T, S, C) that are easy to type. The full option word follows so the label is always intelligible without memorisation. +- The abort/abandon path is always the last option so it does not accidentally attract the user's attention before they read the other options. + +**Progressive disclosure** + +- The resume prompt shows only the phase name and gate number, not the full gate content, until the user chooses "Continue." This prevents information overload when a user opens a session without knowing it has in-progress state. +- The design summary at Gate 2 is capped at three sections (decisions, components, risks) and a maximum of five bullets per section. The user is explicitly directed to the file path for the full document. +- The stall gate shows a "summarised" last output, not a full transcript. Long transcripts would bury the recovery options. + +**Recovery path completeness** + +Every error state provides at least one explicit forward path. No state leaves the user with only a description of what went wrong. Specifically: + +- Every error that names a file path also names the action the user can take on that file. +- Every fetch or network error offers a paste-as-text fallback so the user is never blocked by an unavailable external resource. +- Every gate offers an abort/abandon option so the user can always exit cleanly. + +**Keyboard / interaction model** + +Because this is a CLI chat interface, "keyboard navigation" means: the user types their response and presses Enter. There are no tab-stops, focus traps, or pointer interactions. The design ensures: + +- Option labels (A, E, R, X, T, S, C) are single characters so the user never needs to type a long string to select an option. +- When the user must provide free text (targeted revision reason, rejection reason), the prompt clearly states that free text is expected. It does not present a structured option list for those responses. +- All confirmations that require the user to open a file and return to the chat explicitly state the trigger phrase to continue (e.g., "reply 'done'"). The user is never left wondering what to type to resume. + +**Screen-reader parity** + +Claude Code's CLI output is plain text rendered in a terminal. There are no icon-only buttons, no images, and no non-text content requiring `aria-label`. The ASCII separator lines (`───────────────────`) used for visual grouping in gate prompts are decorative and acceptable in this medium; they are not structural elements. If a screen reader reads them aloud, the content remains fully intelligible without them. + +--- + +### Requirements coverage — Part A + +| REQ ID | Requirement summary | Addressed in Part A | +|---|---|---| +| REQ-ORCH-006 | Goal-loop entry from free-text problem statement | Flow A1 | +| REQ-ORCH-007 | Goal-loop entry from GitHub issue reference | Flow A2; error state: issue fetch failure | +| REQ-ORCH-008 | Scope phase: EARS extraction and Gate 1 HITL | Gate 1 design; Flow A1/A2 | +| REQ-ORCH-009 | Research wave: parallel analyst dispatch | Flow A4 status messages | +| REQ-ORCH-010 | Research wave: de-duplicated synthesis | Flow A4 status messages | +| REQ-ORCH-011 | Design synthesis: Gate 2 HITL | Gate 2 design; Flow A4/A5 | +| REQ-ORCH-012 | Plan phase: tasks.md with DAG edges | Flow A5; plan transition message | +| REQ-ORCH-013 | Implement waves: parallel wave dispatch | Flow A6 status messages | +| REQ-ORCH-014 | Stall detection: escalation after 3 retries | Stall gate design; Flow A8 | +| REQ-ORCH-015 | Review phase: Gate 3 HITL | Gate 3 design; Flow A7 | +| REQ-ORCH-016 | Session summary on loop completion | Flow A9 | +| REQ-ORCH-022 | workflow-state.md written before every AskUserQuestion | Noted at each gate trigger condition | +| REQ-ORCH-023 | /issue:tackle absorbed as orchestrator entry mode | Flow A3 | +| REQ-ORCH-003 | Pre-flight precondition check | Error state: missing artifact | + +**Requirements not in Part A scope (covered by Part B or Part C):** + +| REQ ID | Part | +|---|---| +| REQ-ORCH-001 | Part C (architect) — Agent tool dispatch mechanism | +| REQ-ORCH-002 | Part C — workflow-state.md ownership | +| REQ-ORCH-004 | Part C — model selection | +| REQ-ORCH-005 | Part C — slash command backward compatibility | +| REQ-ORCH-017 | Part C — plugin manifest | +| REQ-ORCH-018 | Part C — settings.json | +| REQ-ORCH-019 | Part C — build pipeline | +| REQ-ORCH-020 | Part C — agent frontmatter validation | +| REQ-ORCH-021 | Part C — non-plugin-user compatibility | + +--- + +## Part B — UI + +### Key screens / states + +In a CLI conversational context, a "screen" is a distinct orchestrator output state that the user encounters during a goal-loop session. Each state is triggered by a specific system event and follows a defined content pattern. Twelve states cover the full session lifecycle. + +| State | Trigger | Purpose | Content pattern | +|---|---|---|---| +| Welcome | Session opens; no in-progress session detected; first message is not a recognisable problem statement or command | Orient a new user. | Plain text: welcome line, two examples of valid input, mention of `/spec:*` fallback. No separator line. | +| Gate 1 — Scope confirmation | grill skill returns structured EARS criteria. `workflow-state.md` written first. | User approves, edits, or aborts the extracted scope before any autonomous work begins. | Gate header → numbered criteria list (ACCEPT CRITERIA block) → option list (A / E / X). | +| Progress — research wave | Gate 1 approved. | Prevent the user from thinking the session has stalled during autonomous analyst dispatch. | Single status line with `→` prefix, phase label, count of agents dispatched. No interaction expected. | +| Progress — design synthesis | Research wave complete and merged. | Signal transition from research to design. | Single status line with `→` prefix and artifact name. | +| Gate 2 — Design approval | Architect subagent writes `design.md`. `workflow-state.md` written first. | User approves, edits, or rejects the design before implementation begins. | Gate header → three-section DESIGN SUMMARY block (decisions · components · risks) → option list (A / E / R). File path shown in code span. | +| Progress — plan phase | Gate 2 approved. | Signal decomposition is running. | Single status line with task and wave counts. | +| Progress — implement wave N | Each wave starts. | Confirm parallel execution is underway; prevent perceived stall during multi-minute waves. | Status line: wave N of M, task count, "in parallel worktrees". | +| Stall gate | Stall counter reaches 3 for a given task. `workflow-state.md` written first. | Surface a stuck task and give the user explicit control before any further retry. | Gate header → TASK DETAILS block (task ID, phase, retry count, summarised last output) → option list (R / S / X). | +| Gate 3 — Review verdict | Reviewer and QA subagents return. `workflow-state.md` written first. | User accepts results or requests targeted revision of specific failing criteria. | Gate header → ACCEPTANCE CRITERIA — REVIEW RESULTS table (criterion · PASS/FAIL · one-line evidence) → overall tally → option list (A / T). | +| Session summary | Gate 3 accepted; `session-summary.md` written; `workflow-state.md` updated to `complete`. | Close the loop; give the user paths to all produced artifacts. | Single confirmation line → bulleted artifact list in code spans. | +| Resume prompt | Session opens; `workflow-state.md` exists with an in-progress goal-loop. | Let the user resume, restart, or abandon without re-running prior phases. | Gate header → interrupted-at line → last-saved timestamp → comma-separated artifact list → option list (C / R / A). | +| Error state | Various: missing artifact, issue fetch failure, grill failure, wave execution error, corrupted session state. | Name what failed, explain in one sentence, offer at least one forward path. | Gate header (naming the error type) → one-sentence cause → labeled forward-path options as middle-dot bullets. | + +--- + +### Components + +In a CLI context, "components" are repeatable output patterns — formatted text blocks that appear across multiple states. Six patterns cover the full goal-loop surface. + +#### 1. Progress banner + +Used for all non-interactive status messages between phases. The user must not reply to a progress banner. + +Format: + +``` +→ [phase-label] +``` + +Rules: +- Prefix is `→` (U+2192) followed by a single space, then the phase label in square brackets, then a space, then the message. +- The phase label uses the tokens defined in the Tokens section below. +- The message is one sentence, present continuous tense, ending with `...` when work is still running, or a period when the step is complete. +- No separator line before or after a progress banner. It is inline with the conversation flow. +- Never begins with "I" — write "Fetching issue #501..." not "I am fetching issue #501...". + +Example (research wave start): + +``` +→ [research-wave] Dispatching 3 analyst agent(s)... +``` + +Example (research complete): + +``` +→ [research-wave] 3 finding(s) merged into `specs/auth-rework/research.md`. +``` + +#### 2. Gate header + +Used to open every AskUserQuestion gate call and every stall or error state that requires a user decision. The gate header visually separates the interactive state from the preceding progress stream. + +Format: + +``` +Goal-loop · [feature-slug] · [Gate name] +``` + +Rules: +- The full line is the first line of the gate block. No blank line before it within the AskUserQuestion call. +- `Goal-loop` is literal, sentence-case. `·` (middle dot, U+00B7) is the separator; one space on each side. +- `[feature-slug]` is the derived slug in kebab-case, not in code span — it is display text. +- `[Gate name]` is the human-readable gate name in sentence case, followed by nothing (no period, no colon). +- On the line immediately following the gate header, print an ASCII separator: `───────────────────` (em-dash-style box-drawing characters). This is the only separator style used; do not use `---` or blank lines as visual separators within gate blocks. + +Example: + +``` +Goal-loop · auth-rework · Scope confirmation +─────────────────── +``` + +This separator is the same character used in the UX Part A gate sketches; it is consistent with the existing convention established there. + +#### 3. Criteria list + +Used inside Gate 1 (scope confirmation) to present EARS acceptance criteria for user review. + +Format: + +``` +ACCEPTANCE CRITERIA +─────────────────── +1. [EARS criterion text — full sentence as produced by the grill skill] +2. [EARS criterion text] +3. [EARS criterion text] +``` + +Rules: +- The block heading `ACCEPTANCE CRITERIA` is all-caps (consistent with the other block headings in Part A gate sketches: `TASK DETAILS`, `DESIGN SUMMARY`). No colon. +- Followed immediately by a separator line (same style as the gate header separator). +- Criteria are numbered, not bulleted. Numbers are flush-left. +- Each criterion is one line. If a criterion wraps in the terminal, the continuation is indented two spaces to align under the first character of the criterion text. Do not truncate long criteria. +- EARS pattern type (Ubiquitous, Event-driven, etc.) is not shown to the user. The user evaluates the criterion text, not the pattern label. Pattern metadata lives in `scope.md`. +- No trailing punctuation is added to criteria; they are presented as the grill skill produced them. + +#### 4. Pass/fail verdict table + +Used inside Gate 3 (review verdict) to show criterion-by-criterion review results. This is the primary decision support for the most consequential gate. + +Format: + +``` +ACCEPTANCE CRITERIA — REVIEW RESULTS +────────────────────────────────────── +1. [Criterion text, truncated at 52 chars if needed] PASS [one-line evidence] +2. [Criterion text] PASS [one-line evidence] +3. [Criterion text] FAIL [one-line gap description] +4. [Criterion text] PASS [one-line evidence] + +Overall: [N] passed, [M] failed. +``` + +Rules: +- The block heading and separator follow the same convention as the criteria list. +- `PASS` and `FAIL` are all-caps, fixed-width column (6 chars including trailing space). Align the evidence column after the verdict. +- Criterion text is left-aligned, padded to a fixed width. If the full criterion text would make the row exceed 100 characters, truncate with `...` at 52 characters. The full text is always in `scope.md`. +- Evidence is plain text, maximum one line. Do not wrap evidence; truncate at 60 characters with `...` if the reviewer returned more. +- The `Overall` tally line is separated from the table by one blank line. +- PASS/FAIL is never indicated by color or symbol only — the words `PASS` and `FAIL` are always spelled out. This ensures accessibility in monochrome and screen-reader contexts. + +#### 5. Artifact link + +Used when the orchestrator references a file produced or consumed during the session. File paths are always shown in code spans and relative to the repository root. + +Format: `` `specs//` `` + +Rules: +- Always relative to repository root. Never absolute. +- Always in a code span (backtick-delimited in Markdown; rendered as monospace in Claude Code output). +- When listing multiple artifacts (e.g., in the session summary or session resume prompt), use a bullet list where each bullet contains exactly one code span. +- When a file path appears inside a sentence, it remains in a code span but is not put on its own line. +- Never use a trailing slash for directory references; always name the specific file. + +Example (in session summary): + +``` +Artifacts produced: + · `specs/auth-rework/scope.md` + · `specs/auth-rework/research.md` + · `specs/auth-rework/design.md` + · `specs/auth-rework/tasks.md` + · `specs/auth-rework/session-summary.md` +``` + +#### 6. Option labels + +Used in every AskUserQuestion gate call. Options are the only interactive elements in a goal-loop session. + +Format: + +``` + [LETTER] [Option word] — [one-sentence description of what happens next] +``` + +Rules: +- Two spaces before the letter, two spaces after, then the option word in sentence case, then an em-dash (` — `), then the consequence. +- Letters are single uppercase characters. The letter mnemonically matches the option word where possible (A = Approve, E = Edit, R = Reject/Retry, X = Abort, T = Targeted revision, S = Skip, C = Continue). +- Option words are 1–5 words, imperative mood: `Approve`, `Edit`, `Reject`, `Retry`, `Skip`, `Abort session`, `Targeted revision`, `Continue`, `Restart`, `Abandon`. +- The consequence is one sentence, plain English, no jargon. It describes what the orchestrator will do next, not what the user should do. +- The abort/abandon/abort-session option is always last in the list. +- No period at the end of the consequence line. +- Inline notes (e.g., the cascade warning for the Skip option at the stall gate) appear indented under the consequence on the next line, prefixed with ` ` (five spaces to align under the consequence text). + +--- + +### Tokens + +In a CLI conversational context, tokens are formatting conventions — the rules for when and how to use Markdown emphasis, separators, prefixes, and path notation. These conventions are derived from examining existing SKILL.md files and agent definitions in the codebase, then extended only where the goal-loop surface requires something not yet defined. + +#### Emphasis conventions + +| Need | Convention | Rationale | +|---|---|---| +| File path or command in running text | `` `code span` `` | Consistent with all existing SKILL.md files and agent definitions. | +| Block heading inside a gate or error state | `ALL-CAPS PLAIN TEXT` (no Markdown bold) | All-caps headings are used in Part A gate sketches (`ACCEPTANCE CRITERIA`, `DESIGN SUMMARY`, `TASK DETAILS`). They render clearly in both Markdown and plain-text terminal output. | +| Inline emphasis of a key term or decision | `**bold**` | Used sparingly: only for a term the user must act on (e.g., the task ID in a stall gate). Not used for decoration. | +| Phase names in prose | `[phase-label]` in square brackets | Matches the phase label token style (see below). | +| Italic | Not used | Italic rendering is inconsistent across terminal emulators. The brand voice is direct; italics add no value here. | + +#### Separator style + +A single separator style is used throughout: + +``` +─────────────────── +``` + +This is the box-drawing character U+2500 (`─`), repeated. Length is 19 characters for the gate-header separator; length matches the heading width for content-block separators. This style is established in Part A gate sketches and is consistent with the existing tool-output convention in this codebase (e.g., the orchestrator agent's plain-text output block, the grill skill's output pattern). It renders cleanly as ASCII in all terminal emulators and is read aloud by screen readers as a series of dashes, which does not obscure content. + +`---` (Markdown horizontal rule) is not used inside gate blocks. It is valid in section breaks of Markdown documents (e.g., this design.md) but would conflict with Claude Code's Markdown rendering when embedded in conversational output. + +Blank lines are used as paragraph separators within a gate block (e.g., between the header block and the option list, between the verdict table and the overall tally). They are not used as visual dividers. + +No emoji prefixes. The Specorator brand uses zero emoji anywhere in its product page or documentation, and this convention extends to CLI output. + +#### Status line prefix + +All progress banners begin with `→` (U+2192) followed by a single space and the phase label. This character is used throughout the Specorator brand as the standard "next" or "advancing" indicator (SKILL.md files, the design system README). It is the only prefix used for progress banners. + +Error and forward-path option bullets use `·` (middle dot, U+00B7) as the bullet character. This is consistent with the existing brand convention for meta-item separation and option lists outside AskUserQuestion gates (e.g., the forward-path options in error states that do not warrant a full gate call). + +Inside AskUserQuestion option lists, the prefix is the option letter followed by two spaces (not a bullet character). + +#### File path format + +All file paths: +- Are relative to the repository root. +- Are wrapped in a code span: `` `specs//.md` ``. +- Use forward slashes regardless of platform. +- Never use `./` or `../` prefixes. +- Are listed one per bullet when appearing in a list. + +#### Phase label convention + +Phase labels appear inside square brackets at the start of progress banners and in gate headers. The canonical set for this feature: + +| Phase | Label | +|---|---| +| Scope phase | `[scope]` | +| Research wave | `[research-wave]` | +| Design synthesis | `[design]` | +| Plan phase | `[plan]` | +| Implement wave | `[wave-N]` where N is the wave number (e.g., `[wave-1]`, `[wave-2]`) | +| Review phase | `[review]` | +| Session complete | `[done]` | + +Gate headers do not use phase labels — they use the human-readable gate name after the feature slug (e.g., "Scope confirmation", "Design approval", "Review verdict"). + +--- + +### Content + +#### Tone and vocabulary + +**Voice in status messages.** The orchestrator speaks in first person, present continuous or simple present. "Dispatching 3 analyst agent(s)..." not "3 analyst agents have been dispatched." Short, direct, no hedging. This matches the Specorator brand voice: "opinionated, predictable, direct." + +**Tense rules by message type:** + +| Message type | Tense | Example | +|---|---|---| +| Work in progress | Present continuous + `...` | `Dispatching 3 analyst agent(s)...` | +| Phase complete | Simple past, period | `3 finding(s) merged into research.md.` | +| Gate context sentence | Simple present | `The architect has produced a design document.` | +| Forward-path consequence | Simple future | `Orchestrator advances to the research wave.` | +| Error explanation | Simple past | `Could not read GitHub issue #501.` | + +**How to refer to subagents in user-facing copy.** Users do not need to know the word "subagent." Use the role's function instead: + +| Internal term | User-facing copy | +|---|---| +| analyst subagent | analyst agent | +| architect subagent | the design document generator (in error copy only); "the architect" (in gate copy where precision matters) | +| planner subagent | the task planner | +| dev/qa subagents | task agents | +| reviewer subagent | the reviewer | + +"Agent" is acceptable in user-facing copy because it is used natively by Claude Code and is familiar to the target persona (senior solo developer, small engineering team). "Subagent" is never used in user-facing copy. + +**How to refer to the goal-loop.** The goal-loop is never called that in user-facing output. Refer to it as "this session" (in progress messages and error states) or use no name at all when the context is clear. In session-boundary messages (resume prompt, session summary, abandon message), "goal-loop session" is acceptable because the user needs to understand they are interacting with a session object that can be resumed or abandoned. + +**Vocabulary for Gate 3 resolution options.** At Gate 3, the user is choosing what happens to the completed implementation work: + +- `Accept` — not "approve" (approve implies the work is conditional; accept implies the work is sufficient and the session can close). +- `Targeted revision` — not "fix" (too casual) and not "reject" (implies discarding all work; only specific tasks are re-run). + +**Vocabulary for Gate 1 and Gate 2 approval options.** At Gate 1 and Gate 2: +- `Approve` — confirms the extracted or produced artifact and authorises the next phase to begin. +- `Edit` — signals the user will modify the file and return. +- `Reject` — at Gate 2 only; signals the design is structurally wrong and research must restart with new context. +- `Abort` — stops the session cleanly and writes no further artifacts. + +**Forbidden words in orchestrator output.** Consistent with the Specorator brand voice rules: +- Never: "seamlessly", "magical", "revolutionary", "AI-powered", "leverage", "supercharge." +- Never: "subagent" in user-facing output. +- Never: "please" in status messages (it is padding; the user knows the orchestrator is not sentient). +- Never: "Something went wrong." Every error message names what went wrong and why. This is enforced by design goal DG3. + +#### Microcopy standards by state + +**Welcome message.** Sentence-case. Two sentences maximum for the orientation line. Examples are indented under a short lead-in. No period on example lines (they are illustrative, not statements). Mention of `/spec:*` commands is present but subordinate — it is the last sentence. + +**Gate context anchor sentences.** The first sentence of every gate block after the separator line names what the orchestrator did and what artifact resulted. "The architect has produced a design document (`specs/auth-rework/design.md`)." The user knows where to look before they see the options. + +**Error state heading.** The gate header for error states uses a descriptive name that names the problem category, not a generic "Error." Examples: "Missing prerequisite", "Could not fetch issue", "Scope extraction incomplete", "Task failed", "Task stalled", "Session state unreadable." Each name is a noun phrase in sentence case. No exclamation mark. + +**Forward-path options in error states.** Presented as middle-dot bullets, not as a full AskUserQuestion option list, when the error is recoverable by a free-text reply (e.g., "reply 'done'" or "reply 'abort'"). AskUserQuestion with labeled options (A/R/X) is used only when the error has discrete branching paths that warrant distinct handling. + +**Session summary.** Closes with a single confirmation line in simple past tense: "Goal-loop complete." followed by the path to `session-summary.md` on the next line as a code span. Then the artifact list. No closing salutation or congratulatory language. + +**Slug in user-facing copy.** The feature slug is displayed in kebab-case without code span formatting in gate headers (it is a display identifier). It is shown in a code span only when it appears as part of a file path. + +#### Requirements coverage — Part B + +| REQ ID | Requirement summary | Addressed in Part B | +|---|---|---| +| REQ-ORCH-006 | Goal-loop entry from free-text problem statement | Welcome state content pattern | +| REQ-ORCH-007 | Goal-loop entry from GitHub issue reference | Progress banner for issue fetch; error state for issue fetch failure | +| REQ-ORCH-008 | EARS extraction and Gate 1 HITL | Gate 1 formatting: gate header, criteria list component, option labels | +| REQ-ORCH-009 | Research wave parallel dispatch | Progress banner — research wave; phase label `[research-wave]` | +| REQ-ORCH-010 | Research synthesis | Progress banner — design synthesis transition line | +| REQ-ORCH-011 | Gate 2 HITL design approval | Gate 2 formatting: gate header, DESIGN SUMMARY block, option labels; artifact link convention | +| REQ-ORCH-012 | Plan phase tasks.md | Progress banner — plan phase | +| REQ-ORCH-013 | Implement waves parallel dispatch | Progress banner — implement wave N; phase label `[wave-N]` | +| REQ-ORCH-014 | Stall detection escalation | Stall gate: gate header, TASK DETAILS block, option labels (R/S/X) | +| REQ-ORCH-015 | Review phase Gate 3 HITL | Gate 3: gate header, pass/fail verdict table component, option labels (A/T) | +| REQ-ORCH-016 | Session summary artifact | Session summary state content pattern | +| REQ-ORCH-022 | workflow-state.md written before every AskUserQuestion | Gate header convention notes this; the gate header itself serves as the user signal that state has been persisted | +| REQ-ORCH-023 | /issue:tackle entry | No distinct UI treatment; absorbed into Flow A2 formatting | +| REQ-ORCH-003 | Pre-flight precondition check | Error state: Missing prerequisite; middle-dot forward-path bullets | + +--- + +## Part C — Architecture + +### System overview + +The goal-loop is a purely in-process, file-mediated orchestration system.

Architecture-specific notes follow. + +| Risk reference | Architecture-level note | +|---|---| +| RISK-ORCH-001 (error compounding 17.2x) | Mitigated by: typed output schemas at each phase boundary; reviewer subagent as a blocking check before Gate 3; stall detection preventing infinite loops. | +| RISK-ORCH-002 (parallel write conflicts) | Mitigated by: `isolation: worktree` per dev/qa subagent; orchestrator-mediated merge after each wave via reviewer subagent — not automatic. | +| RISK-ORCH-004 (orchestrator context exhaustion) | Mitigated by: orchestrator reads artifact files by path (not full conversation history); subagents spawn with clean contexts; session summary truncates session state at completion. | +| RISK-ORCH-005 (infinite loops / stalled subagents) | Mitigated by: stall_counters per task in `workflow-state.md`; hard limit of 3 retries before HITL escalation; stall_counters persist across session restarts. | +| RISK-ORCH-006 (decomposition errors) | Mitigated by: planner outputs explicit `depends_on` edges; orchestrator validates acyclicity before writing wave schedule; human review at Gate 2 before implementation begins. | +| RISK-ORCH-007 (agent performance degradation over consecutive runs) | Mitigated by: fresh subagent spawn per task; orchestrator does not reuse persistent agents across phases. | +| RISK-ORCH-008 (plugin manifest naming collision) | Resolved: `plugins/*/manifest.md` (ADR-0036) and `.claude-plugin/plugin.json` are separate files at different paths with separate concerns. `build-claude-plugin.ts` generates the latter and does not touch the former. | +| RISK-ORCH-009 (`settings.json` agent priority) | Documented as known behaviour: Claude Code project settings (`.claude/settings.json`) override plugin settings for the same key. Orchestrator is the plugin default, not forced. | +| RISK-ORCH-012 (orchestrator becoming monolithic) | Mitigated by: decomposing the goal-loop into phase-specific logic sections within the conductor skill; each phase has defined inputs, outputs, and a single responsibility. The orchestrator's system prompt invokes the conductor skill rather than containing all phase logic inline. | + +**Architecture-specific risk (new):** + +| ID | Risk | Severity | Likelihood | Mitigation | +|---|---|---|---|---| +| RISK-ORCH-013 | Orchestrator writes to `specs/` outside the declared write boundary (e.g., overwrites `requirements.md` from a prior stage run) | High | Low | Write boundary documented in ADR-0046 and in orchestrator system prompt; `check-agents.ts` does not enforce path restrictions at runtime — this is a system-prompt-level constraint, not a tool-level one | +| RISK-ORCH-014 | `settings.json` agent key conflict between plugin default and project `.claude/settings.json` | Low | Low | Documented as known behaviour per RISK-ORCH-009; implementation team must test priority resolution during beta | +| RISK-ORCH-015 | Topological sort produces incorrect wave order if planner writes malformed `depends_on` edges (circular or self-referential) | Medium | Low | Orchestrator validates acyclicity via Kahn's BFS before writing wave schedule; self-referential edges are trivially detected; circular dependencies surface as BFS termination failure → orchestrator reports an error and invites user to restart the plan phase | + +--- + +### Performance, security, and observability + +#### Performance + +- **Scope phase (NFR-ORCH-001):** Target ≤ 30 seconds from problem statement to Gate 1. The scope phase is the grill skill running in the orchestrator's context — no subagent dispatch latency. Bottleneck is grill skill iteration count; bounded by early exit on EARS completeness. +- **Research wave parallelism (NFR-ORCH-002):** N analyst subagents dispatched in a single orchestrator turn (parallel Agent tool calls). Wall-clock time scales approximately as the slowest analyst, not as N × analyst-time. This is the primary parallelism mechanism. +- **Design-to-Gate-2 target (NFR-ORCH-006):** ≤ 5 minutes for well-scoped issues (≤ 5 EARS criteria, ≤ 3 research questions). Dominated by architect subagent latency; model selection via `SPECORATOR_HEAVY_MODEL` allows trading cost for quality. +- **Worktree creation overhead:** Each dev/qa subagent with `isolation: worktree` creates a new worktree. On a large monorepo, 5 parallel worktrees may take 10–30 seconds to create. This is logged in `workflow-state.md` as wave start/end timestamps for empirical measurement during beta (per requirements.md open questions). +- **Orchestrator context management:** The orchestrator reads artifact files by path rather than accumulating phase outputs in-context. Each subagent spawns with a clean context (no conversation history). These two mechanisms prevent context rot across a long session. + +#### Security + +- **Write boundary enforcement:** The orchestrator has Write and Edit tools. By convention (enforced in the system prompt and documented in ADR-0046), the orchestrator writes only to `specs//` paths. It does not write to `.claude/`, `docs/`, or any other directory. This is a system-prompt constraint, not a platform-enforced path restriction. +- **GitHub issue content:** The orchestrator reads GitHub issue title and body via the scoped GitHub MCP read tool. This content is passed to the grill skill as the initial problem statement — it is not executed as instructions. Prompt injection via a malicious issue body is mitigated by the grill skill's structured output extraction (EARS criteria, not free-form LLM instructions). +- **Plugin agent frontmatter validation (REQ-ORCH-020 / NFR-ORCH-007):** `check-agents.ts` runs in CI and rejects any plugin agent that declares `hooks`, `mcpServers`, or `permissionMode` in its YAML frontmatter. This prevents a plugin agent from escalating its own permissions. The orchestrator's expanded tool list (`Agent`, `Write`, `Edit`) is declared in frontmatter — this is expected and validated to be present only on the orchestrator definition. +- **Subagent tool isolation:** Subagents do not inherit the Agent tool. The platform hard limit (subagents cannot spawn subagents) ensures the star topology is enforced at the platform level, not just by convention. +- **Plugin bundle trust boundary:** The plugin bundle is distributed via the `dist/claude-plugin` orphan branch (ADR-0043). The bundle contents are generated by `build-claude-plugin.ts` from canonical sources — no hand-edited files in the bundle. Any modification to the canonical sources goes through the standard PR + CI pipeline. + +#### Observability + +The goal-loop has no external telemetry infrastructure. Observability is file-based. + +| Observable | Mechanism | Who reads it | +|---|---|---| +| Current phase | `workflow-state.md#goal_loop.current_phase` | User (session resume), orchestrator (pre-flight checks) | +| HITL gate state | `workflow-state.md#goal_loop.hitl_state` | Orchestrator (session resume replay) | +| Stall events | `workflow-state.md#goal_loop.stall_counters` | Orchestrator (stall detection), user (stall gate prompt) | +| Artifacts produced | `workflow-state.md#goal_loop.artifacts_produced` | User (session resume prompt), orchestrator (pre-flight checks) | +| Wave progress | `workflow-state.md#goal_loop.wave_schedule` (implicit: which waves are complete vs. pending) | Orchestrator (wave advancement) | +| Session outcome | `session-summary.md` | User, teammates, enterprise auditors | +| Phase start/end times | `workflow-state.md#updated` timestamp, refreshed at each write | User (performance tracking) | + +No structured logging to an external system is introduced in v1.

No other tool entries are permitted. The keys `hooks`, `mcpServers`, and `permissionMode` must be absent from the frontmatter. + +- **Behaviour:** + 1. The orchestrator is the root session agent. It is activated as the default session agent when the Specorator plugin is enabled (via `settings.json agent: orchestrator`). + 2. When the plugin is NOT enabled, the orchestrator file remains in `.claude/agents/` as a named agent but is not the default session agent. In this case no goal-loop behaviour is invoked and existing slash-command behaviour is unchanged. + 3. The Agent tool in the orchestrator's tool list grants dispatch authority over specialist subagents (analyst, architect, planner, dev, qa, reviewer). + 4. The Write and Edit tools are constrained by convention (documented in the orchestrator system prompt and in ADR-0046) to writes within `specs//` paths only. The orchestrator does not write to `.claude/`, `docs/`, `templates/`, or any other directory. + 5. Subagents dispatched by the orchestrator do NOT inherit the Agent tool. The platform hard limit (subagents cannot spawn subagents) enforces this at the runtime level. + +- **Pre-conditions:** + - The file `.claude/agents/orchestrator.md` exists with valid YAML frontmatter. + - `check-agents.ts` has run and passed (no prohibited frontmatter keys present). + +- **Post-conditions:** + - When the plugin is active, any free-text message or issue reference submitted by the user as the session's first message is routed to the goal-loop conductor skill by the orchestrator. + - When the plugin is not active, the orchestrator file exists but does not intercept any slash-command execution paths. + +- **Side effects:** None at agent definition level; activation effects are documented in SPEC-ORCH-002 through SPEC-ORCH-010. + +- **Errors:** + - If `hooks`, `mcpServers`, or `permissionMode` appear in the frontmatter, `check-agents.ts` (SPEC-ORCH-017) emits a build error and no bundle is produced. + - If the `tools` list is missing or empty, the Claude Code runtime will treat the agent as having no tool access, preventing goal-loop execution. This is a misconfiguration; no runtime recovery is specified — the implementer must correct the frontmatter. + +- **Satisfies:** REQ-ORCH-001, REQ-ORCH-005, REQ-ORCH-021 + +--- + +### SPEC-ORCH-002 — goal-loop conductor skill entry point + +- **Kind:** Skill invocation (`.claude/skills/goal-loop/SKILL.md`), executed in the orchestrator's context + +- **Signature:** + ``` + Input detection on session opening message: + message: string (the user's first message to the orchestrator) + + Output: one of three routing decisions: + { route: 'scope-phase', input: ProblemStatement } + { route: 'scope-phase', input: IssueContent } + { route: 'command-passthrough' } + + ProblemStatement: + type: 'free-text' + text: string (the full message verbatim) + + IssueContent: + type: 'github-issue' + issue_number: number + issue_url: string | null + title: string (fetched from GitHub) + body: string (fetched from GitHub) + ``` + +- **Behaviour:** + 1. **Input classification.** The orchestrator classifies the user's opening message by the following rules applied in priority order: + - **Slash command:** if the message starts with `/` (Unicode `/`), route to `command-passthrough`. The orchestrator does not intercept slash commands. + - **Issue reference:** if the message matches the issue reference pattern (see pattern below), route to `scope-phase` with `IssueContent`. Fetch the issue before proceeding. + - **Free-text problem statement:** otherwise (non-empty message, no slash prefix, no issue reference), route to `scope-phase` with `ProblemStatement`. + - **Unrecognisable input:** if the message is empty or consists only of whitespace, display the welcome message (defined in design.md Part B) and wait for a new message. Do not enter the goal-loop. + + 2. **Issue reference regex pattern.** The orchestrator matches issue references using the following pattern (applied against the full message string): + ``` + Issue number only: \B#(\d+)\b + Full GitHub issue URL: https://github\.com/[^/\s]+/[^/\s]+/issues/(\d+) + ``` + - `\B#(\d+)\b` — matches `#NNN` where NNN is one or more digits, preceded by a non-word boundary (not alphanumeric or underscore), and followed by a word boundary. This prevents matching `abc#123` in a code snippet. + - The URL pattern captures the issue number from the path. The repository org/name is extracted from the URL path segments (positions 4 and 5 after splitting on `/`). + - If the message contains BOTH a slash command prefix and an issue reference (e.g., `/issue:tackle #501`), the slash command rule takes priority and the message is dispatched as a `/issue:tackle` command. The `/issue:tackle` command handler (SPEC-ORCH-002 item 3) then normalises to an issue reference. + - Only the first matching issue reference in the message is used. + + 3. **`/issue:tackle` normalisation.** When the user invokes `/issue:tackle #NNN` or `/issue:tackle `, the orchestrator: + - Extracts the issue number or URL from the command arguments. + - Treats this as equivalent to submitting that issue reference directly. + - Proceeds identically to the "Issue reference" routing case above. + - The user experience is indistinguishable from submitting the issue reference as a free-text message. + + 4. **workflow-state.md initialisation.** Before entering the scope phase, the orchestrator: + - Checks whether a `workflow-state.md` exists in `specs//` with an in-progress goal_loop block. + - If found: displays the resume prompt (defined in design.md Part A Flow A10) and waits for user choice before proceeding. + - If not found: writes a new `workflow-state.md` with `goal_loop.current_phase: scope` and `goal_loop.hitl_state.pending: false` before invoking the scope phase. + - The feature slug is derived from the first substantive noun phrase of the problem statement or from `issue-` for issue references. If the derived slug conflicts with an existing `specs/` directory, a 4-character lowercase hex suffix is appended (e.g., `auth-rework-a3f1`). The user is informed of the slug in the Gate 1 message. + +- **Pre-conditions:** The orchestrator is the active session agent (plugin settings.json active). + +- **Post-conditions:** + - `command-passthrough` route: no workflow-state changes; command executes through its normal handler. + - `scope-phase` route: `workflow-state.md` is initialised; scope phase begins. + +- **Side effects:** + - On issue reference: reads GitHub issue via GitHub MCP tool (read-only). + - On scope-phase route: creates `specs//workflow-state.md` if not already present. + +- **Errors:** + - GitHub issue fetch fails: display "Could not fetch issue" error message (design.md Part A §Issue fetch failure) via inline message (not AskUserQuestion). Offer: paste-as-text fallback, corrected issue reference, or abort. + - Non-existent issue (GitHub returns 404): display same error with explicit mention of "The issue number does not exist in this repository." + - Empty message: display welcome message; no error state. + +- **Satisfies:** REQ-ORCH-006, REQ-ORCH-007, REQ-ORCH-023 + +--- + +### SPEC-ORCH-003 — Scope phase and Gate 1 contract + +- **Kind:** Phase execution within conductor skill; includes a grill skill invocation and an AskUserQuestion call + +- **Signature:** + ``` + Input: ProblemStatement | IssueContent (from SPEC-ORCH-002) + + Grill skill invocation: + seed_text: string (problem statement text or issue title + "\n\n" + issue body) + Output: EARSCriteriaList + + EARSCriteriaList: + criteria: ScopeCriterion[] (≥1 item; see data structures section) + + Gate 1 AskUserQuestion call: + question: string (formatted per design.md Part A Gate 1 prompt structure) + options: + - label: "A" + text: "Approve — looks right. Start the research phase." + - label: "E" + text: "Edit — open specs/[slug]/scope.md, make changes, reply \"done\"." + - label: "X" + text: "Abort — stop here. No further artifacts will be written." + ``` + +- **Behaviour:** + 1. The orchestrator invokes the grill skill in its own execution context (not as a subagent Agent call). The grill skill's clarifying-question loop runs until EARS criteria are unambiguous or the maximum of 5 grill-rounds is reached. + 2. After the grill skill returns, the orchestrator writes `scope.md` (schema in SPEC-ORCH-012) to `specs//scope.md`. + 3. The orchestrator writes `workflow-state.md` with `goal_loop.hitl_state: {gate: 1, pending: true}` and adds `specs//scope.md` to `goal_loop.artifacts_produced`. + 4. The orchestrator calls `AskUserQuestion` with the Gate 1 prompt (formatted per design.md Part A §Gate 1). The prompt includes: gate header, acceptance criteria as a numbered list (the `criteria[].text` fields from `scope.md`), and the three options (A / E / X). + 5. **On response A (Approve):** The orchestrator updates `workflow-state.md` with `goal_loop.hitl_state.pending: false` and `goal_loop.current_phase: research`, then proceeds to the research wave (SPEC-ORCH-004). + 6. **On response E (Edit):** The orchestrator outputs the path `specs//scope.md` and waits for the user to reply "done" (case-insensitive). On "done", the orchestrator re-reads `scope.md`, re-parses the criteria from the `## Acceptance criteria` section, updates `scope.md` frontmatter field `ears_count` to the new count, and re-presents Gate 1 with the updated criteria list. This cycle repeats until the user chooses A or X. + 7. **On response X (Abort):** The orchestrator updates `workflow-state.md` with `goal_loop.current_phase: aborted`. It outputs: "Session aborted. `specs/[slug]/scope.md` has been written for reference. No other artifacts were produced." The session ends; no further orchestrator actions are taken. + 8. **Grill skill zero-output handling:** If the grill skill returns zero criteria, the orchestrator writes any partial output to `scope.md`, then displays the "Scope extraction incomplete" error message (design.md Part A §Grill skill extraction failure) via inline message. Options offered: edit scope.md manually and reply "done", retry with a narrower description, or abort. This is not a Gate 1 call — it is a recovery path before Gate 1. + 9. **Maximum edit cycles:** There is no enforced limit on the number of times the user may cycle through the Edit path at Gate 1. Each cycle re-presents the same Gate 1 prompt with the updated criteria. + +- **Pre-conditions:** Problem statement or issue content is non-empty. + +- **Post-conditions:** + - A: `scope.md` is written and non-empty; `workflow-state.md` reflects `current_phase: research`; `hitl_state.pending: false`. + - E: `scope.md` is re-read and frontmatter `ears_count` is updated; Gate 1 is re-presented. + - X: `workflow-state.md` reflects `current_phase: aborted`; only `scope.md` and `workflow-state.md` have been written. + +- **Side effects:** + - Writes `specs//scope.md`. + - Writes and updates `specs//workflow-state.md`. + +- **Errors:** + - `scope.md` write fails (disk error): surface error message naming the path; offer retry or abort. + +- **Satisfies:** REQ-ORCH-008, REQ-ORCH-022 + +--- + +### SPEC-ORCH-004 — Research wave + +- **Kind:** Phase execution within conductor skill; includes parallel Agent tool calls + +- **Signature:** + ``` + Input: ScopeContext + slug: string + criteria: ScopeCriterion[] + scope_md_path: string (e.g., "specs//scope.md") + + Research question derivation: + N: integer (1–5) — researcher count determined by scope surface area heuristic + questions: string[] — N distinct bounded research questions + + Parallel Agent tool call contract (per analyst subagent): + agent: "analyst" (existing analyst agent definition) + prompt: ResearchPrompt (see below) + model: string | undefined (SPECORATOR_HEAVY_MODEL NOT applied to analysts) + + ResearchPrompt: + task: string (bounded research question — max 120 words) + context_path: string (path to scope.md for reference) + instruction: "Return findings as a structured list.

Do not repeat findings from + other researchers — focus on your assigned question." + + Return from each analyst: + findings: ResearchFinding[] (see data structures section) + OR empty output (treated as zero findings for this analyst) + ``` + +- **Behaviour:** + + **Researcher count heuristic (N determination):** + The orchestrator determines N by counting the number of distinct "surface dimensions" in the scope criteria list: + - 1–2 criteria, single area of change → N = 1 + - 3–4 criteria, or criteria that span two identifiable concern areas → N = 2 + - 5–7 criteria, or criteria spanning three concern areas → N = 3 + - 8–10 criteria, or criteria spanning four concern areas → N = 4 + - 11+ criteria, or criteria spanning five or more concern areas → N = 5 + - N is always clamped to the range [1, 5]. + - A "concern area" is identified by the orchestrator from the criterion texts: common areas include data model, API behaviour, security, performance, and UI/UX. The orchestrator assigns each criterion to its primary concern area; distinct areas drive the count. + - The determined N is written to `workflow-state.md` field `goal_loop.researcher_count` before any Agent calls are issued. + + **Question assignment:** + - Each analyst receives a distinct question targeting one concern area. + - No two analysts receive the same question. + - Questions are bounded (max 120 words) and derived from the scope criteria. The orchestrator must not include the full criteria text in the question — only the aspect relevant to that analyst's concern area. + + **Parallel dispatch:** + - The orchestrator issues all N Agent tool calls in a SINGLE orchestrator turn (parallel execution). + - The orchestrator emits the status banner `→ [research-wave] Dispatching [N] analyst agent(s)...` immediately before issuing the calls. + - The orchestrator waits for all N calls to complete before proceeding. + + **De-duplication algorithm:** + - After all analysts return, the orchestrator de-duplicates findings using the following rules: + 1. Two findings are considered duplicates if their heading sentences are semantically equivalent (same factual claim, possibly different phrasing) OR if their supporting detail overlaps by more than 60% of key claims. + 2. When a duplicate is detected, the finding from the analyst with the lower index (first dispatched) is retained; the duplicate is discarded. + 3. Attribution is preserved: the retained finding's `analyst_index` field records all analyst indices that surfaced the same finding (e.g., `analyst_index: [0, 2]`). + - The de-duplication step is performed in-context by the orchestrator (not by a subagent). + + **research.md write:** + - The orchestrator writes `specs//research.md` with the merged, de-duplicated findings. + - Format: standard research.md header (matching existing `/spec:research` output format), followed by findings grouped by concern area, with attribution comments. + - Attribution format per finding: `` HTML comment on the line preceding the finding heading. + - After writing, the orchestrator adds `specs//research.md` to `workflow-state.md`'s `goal_loop.artifacts_produced`. + + **Zero-results handling:** + - If ALL analysts return empty output or findings that de-duplicate to zero items, the orchestrator displays the "Research wave returned no findings" inline message (design.md Part A §Research wave returns no findings) and proceeds to design synthesis with scope criteria only. + - This is not an AskUserQuestion gate call; the user is informed but not blocked. + - `research.md` is still written, with a body stating: `No findings were returned by the research wave. Design synthesis will use scope criteria only.` + + **Partial results:** + - If some analysts return findings and some return empty output, the non-empty results are used. The user is not notified about the partial return unless zero total findings result. + +- **Pre-conditions:** `scope.md` exists and is non-empty; Gate 1 has been approved. + +- **Post-conditions:** `research.md` exists and is non-empty (even if containing only the zero-findings notice); `workflow-state.md` `goal_loop.researcher_count` is set; design synthesis phase begins. + +- **Side effects:** + - Writes `specs//research.md`. + - Updates `workflow-state.md` `goal_loop.researcher_count` and `goal_loop.artifacts_produced`. + +- **Errors:** + - All analyst Agent calls fail (tool error, not empty output): display "Research wave failed" inline message naming the error; offer retry (re-dispatch all analysts) or proceed to design with scope criteria only. + +- **Satisfies:** REQ-ORCH-009, REQ-ORCH-010 + +--- + +### SPEC-ORCH-005 — Design synthesis phase and Gate 2 contract + +- **Kind:** Phase execution; single Agent tool call (architect subagent); AskUserQuestion call + +- **Signature:** + ``` + Architect subagent Agent call: + agent: "architect" + prompt: + scope_md_path: "specs//scope.md" + research_md_path: "specs//research.md" + instruction: "Read scope.md and research.md at the given paths. + Produce specs//design.md following the design.md template convention. + The design must address all acceptance criteria in scope.md. + Write the file to disk before returning." + model: string | undefined (SPECORATOR_HEAVY_MODEL if set — REQ-ORCH-004) + + Gate 2 AskUserQuestion call: + question: string (formatted per design.md Part A Gate 2 prompt structure, including + inline design summary extracted from design.md) + options: + - label: "A" + text: "Approve — proceed to planning and implementation." + - label: "E" + text: "Edit — open specs/[slug]/design.md, make changes, reply \"done\"." + - label: "R" + text: "Reject — provide a reason and I will restart the research phase with your feedback." + ``` + +- **Behaviour:** + 1. The orchestrator emits status banner `→ [design] Producing design document...` before dispatching the architect. + 2. Pre-flight check: both `specs//scope.md` and `specs//research.md` must exist and be non-empty. If either is absent or empty, surface the "Missing prerequisite" error (design.md Part A §Precondition check failure) and do not dispatch the architect. + 3. The orchestrator dispatches a SINGLE architect Agent call. If `SPECORATOR_HEAVY_MODEL` env var is set and non-empty, its value is passed as the `model` parameter of the Agent call. + 4. After the architect returns, the orchestrator verifies that `specs//design.md` exists and is non-empty. If absent, display "Missing prerequisite" error with artifact = `design.md`. + 5. The orchestrator extracts an inline summary from `design.md` by reading the following sections: the first `## Key decisions` table (up to 3 rows), the first `## Components` table (up to 5 rows), and the first `## Risks` section (up to 3 items). If these sections are absent, the orchestrator uses any available summary content. + 6. The inline summary is truncated to at most: 3 architecture decision bullets, 5 component bullets, 3 risk bullets (as specified in design.md Part A Gate 2 §Design rationale). + 7. The orchestrator writes `workflow-state.md` with `goal_loop.current_phase: design`, `goal_loop.hitl_state: {gate: 2, pending: true}`, and adds `specs//design.md` to `goal_loop.artifacts_produced`. + 8. The orchestrator calls `AskUserQuestion` with the Gate 2 prompt. + 9. **On response A (Approve):** Update `workflow-state.md` to `current_phase: plan`, `hitl_state.pending: false`. Proceed to plan phase (SPEC-ORCH-006). + 10. **On response E (Edit):** Output the path `specs//design.md` and wait for "done". On "done", re-read `design.md`, re-extract the inline summary, and re-present Gate 2. + 11. **On response R (Reject):** The orchestrator issues a follow-up inline message asking: "Briefly describe what is wrong with this design." (not an AskUserQuestion call — a plain text prompt). The user replies with free text. The orchestrator records the rejection reason in `workflow-state.md` body under a `## Rejection notes` section (appended, not overwriting). The orchestrator updates `workflow-state.md` to `current_phase: research` and re-enters the research wave (SPEC-ORCH-004) with the rejection note appended to the scope context passed to analysts. + +- **Pre-conditions:** + - `scope.md` and `research.md` exist and are non-empty. + - Gate 1 has been approved. + +- **Post-conditions:** + - A: `design.md` exists; `workflow-state.md` reflects `current_phase: plan`. + - E: `design.md` is re-read; Gate 2 is re-presented. + - R: Rejection reason written to `workflow-state.md`; research wave re-entered. + +- **Side effects:** + - Writes/overwrites `specs//design.md` (via architect subagent). + - Updates `workflow-state.md` multiple times (before dispatch, before Gate 2, on gate resolution). + +- **Errors:** + - `design.md` absent after architect returns: "Missing prerequisite — design.md" error message.

Pre-flight check: `scope.md` and `design.md` must exist and be non-empty. + 2. Orchestrator emits `→ [plan] Decomposing design into tasks...` before dispatch. + 3. Orchestrator dispatches a SINGLE planner Agent call. + 4. After planner returns, orchestrator verifies `specs/<slug>/tasks.md` exists and is non-empty. + 5. **DAG validation and wave schedule derivation (Kahn's BFS):** + - Parse all task IDs from `tasks.md` (`T-<SLUG>-NNN` headings). + - Parse all `depends_on` lists. + - Validate: every task ID in any `depends_on` list must be present as a task heading in the same file. Unknown ID → error (see Errors below). + - Validate: no self-referential dependency (a task whose `depends_on` contains its own ID). + - Run Kahn's BFS topological sort: + - Compute in-degree for each task (count of tasks that list it as a predecessor). + - Initialise queue with tasks where in-degree = 0 (no dependencies). + - Process queue: assign each dequeued task to the current wave; decrement in-degree of successor tasks; enqueue any successor whose in-degree reaches 0. + - After processing, if any task has in-degree > 0, a cycle exists. + - If a cycle is detected: the orchestrator does not write the wave schedule. It displays an inline error message: "Circular dependency detected in tasks.md. Tasks involved: [list of task IDs with non-zero remaining in-degree]. Please open `specs/<slug>/tasks.md` and resolve the cycle, then reply 'done'." The orchestrator waits for "done" and re-runs validation. + - On successful sort: write the derived wave schedule to `workflow-state.md` `goal_loop.wave_schedule` (array of `{wave: number, task_ids: string[], status: 'pending'}`). + 6.

The grill skill runs in the orchestrator's context (no subagent spawn latency). | +| SPEC-ORCH-004 (Research wave parallelism) | Parallel wall-clock time < sequential time at N=3 | NFR-ORCH-002 | Measurement method: compare `workflow-state.md#updated` timestamps at wave start and wave complete; parallel wall-clock time ≈ slowest analyst latency; sequential would be 3× average analyst latency. Parallelism is enforced by the single-orchestrator-turn dispatch requirement. | +| SPEC-ORCH-008 (Stall detection threshold) | ≤ 3 retries per subagent | NFR-ORCH-003 | Hard limit: stall gate fires exactly at `stall_counters[task_id] == 3`.

Budget allocation: scope phase ≤ 30s; research wave (N=1–2) ≤ 90s; design synthesis (architect subagent) ≤ 120s; orchestrator processing ≤ 30s. Heavy model selection via SPECORATOR_HEAVY_MODEL may affect architect latency. | +| SPEC-ORCH-016 (Plugin build with --check) | Exit code 0 before any dist/claude-plugin update | NFR-ORCH-005 | Enforced structurally: `--check` runs before dist update in build script.

The orchestrator only intercepts session-opening free-text messages and issue references when active as the default session agent. Slash commands bypass the goal-loop entry point entirely (route: `command-passthrough` in SPEC-ORCH-002). +- **Non-plugin users:** If the Specorator plugin is NOT enabled (`settings.json agent: orchestrator` not active), the orchestrator agent definition exists in `.claude/agents/` but is not the default session agent. The existing advisory-only orchestrator behaviour is superseded when the plugin is active; without the plugin, the user's existing session agent (if any) remains in effect. +- **workflow-state.md extension is additive:** Existing `workflow-state.md` files without a `goal_loop` block are valid under the extended Zod schema. No migration of existing `specs/*/workflow-state.md` files is required or performed. + +### New artifacts + +- `specs/<slug>/scope.md` and `specs/<slug>/session-summary.md` are new artifact types. No existing file is replaced or renamed. No migration of existing `specs/` directories is required — these files only appear in directories created by a goal-loop session. + +### Plugin deployment + +- The plugin is distributed via the `dist/claude-plugin` orphan branch (ADR-0043). Enabling the plugin activates orchestrator-first behaviour; disabling it restores the previous session behaviour. No configuration changes are required for non-plugin users. + +### Versioning + +- `plugin.json#version` tracks `package.json#version`. All plugin bundle updates increment the package version per standard semver conventions. +- The `workflow-state.md` Zod schema is extended additively (ADR-0047).

The spec.md author must specify: (1) the exact Zod schema fields for the goal_loop block, (2) the full state machine for workflow-state.md transitions, (3) the check-agents.ts validation rules, and (4) the build-claude-plugin.ts settings.json generation mechanism. + +## Open clarifications + +_None._ From a0be0e1736a0d139ede1f73e0095eb989440e418 Mon Sep 17 00:00:00 2001 From: Luis Mendez <3923861+Luis85@users.noreply.github.com> Date: Thu, 14 May 2026 02:26:00 +0200 Subject: [PATCH 06/17] fix(specs): fix CI spell check and verify failures on workflow-state --- specs/goal-oriented-orchestrator-plugin/research.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/specs/goal-oriented-orchestrator-plugin/research.md b/specs/goal-oriented-orchestrator-plugin/research.md index dce4fc7fb..4d72e4217 100644 --- a/specs/goal-oriented-orchestrator-plugin/research.md +++ b/specs/goal-oriented-orchestrator-plugin/research.md @@ -252,7 +252,7 @@ Implement the goal-loop as a new conductor skill (`goal-loop` or `orchestrate-is - [Anthropic — Building effective AI agents](https://resources.anthropic.com/building-effective-ai-agents) - [LangGraph — Interrupts (HITL)](https://docs.langchain.com/oss/python/langgraph/interrupts) - [LangGraph — Making it easier to build human-in-the-loop agents](https://www.langchain.com/blog/making-it-easier-to-build-human-in-the-loop-agents-with-interrupt) -- [Microsoft Research — Magentic-One: A Generalist Multi-Agent System](https://www.microsoft.com/en-us/research/articles/magentic-one-a-generalist-multi-agent-system-for-solving-complex-tasks/) +- [Microsoft Research — Magnetic-One: A Generalist Multi-Agent System](https://www.microsoft.com/en-us/research/articles/magentic-one-a-generalist-multi-agent-system-for-solving-complex-tasks/) - [Towards Data Science — Why Your Multi-Agent System is Failing: The 17x Error Trap](https://towardsdatascience.com/why-your-multi-agent-system-is-failing-escaping-the-17x-error-trap-of-the-bag-of-agents/) - [Anthropic — Building agents with the Claude Agent SDK](https://claude.com/blog/building-agents-with-the-claude-agent-sdk) - [GitHub Blog — From idea to PR: a guide to GitHub Copilot's agentic workflows](https://github.blog/ai-and-ml/github-copilot/from-idea-to-pr-a-guide-to-github-copilots-agentic-workflows/) From a7aa87e76bd9d84445cd1e353e729a2e4492f46c Mon Sep 17 00:00:00 2001 From: CI Fix <ci-fix@example.com> Date: Thu, 14 May 2026 00:28:07 +0000 Subject: [PATCH 07/17] fix(specs): fix traceability and spell check CI failures in ORCH spec - design.md: replace T-AUTH-NNN placeholder IDs with T-ORCH-NNN to match workflow area ORCH (fixes 4 check:traceability area-mismatch errors) - spec.md: add REQ-ORCH-* covering references to TEST-ORCH-038/039/040/042/044/045 rows that only cited EC-ORCH-* IDs (fixes 6 check:traceability coverage errors) - spec.md: fix 'unparseable' -> 'unparsable' (fixes typos spell check failure) https://claude.ai/code/session_011TPNgd7jBv3ySSyvaTifA1 --- specs/goal-oriented-orchestrator-plugin/design.md | 6 +++--- specs/goal-oriented-orchestrator-plugin/spec.md | 14 +++++++------- 2 files changed, 10 insertions(+), 10 deletions(-) diff --git a/specs/goal-oriented-orchestrator-plugin/design.md b/specs/goal-oriented-orchestrator-plugin/design.md index 0cae0cb36..774b88575 100644 --- a/specs/goal-oriented-orchestrator-plugin/design.md +++ b/specs/goal-oriented-orchestrator-plugin/design.md @@ -1219,11 +1219,11 @@ goal_loop: researcher_count: 3 # how many analyst subagents were dispatched wave_schedule: - wave: 1 - task_ids: [T-AUTH-001, T-AUTH-002] + task_ids: [T-ORCH-001, T-ORCH-002] - wave: 2 - task_ids: [T-AUTH-003] + task_ids: [T-ORCH-003] stall_counters: - T-AUTH-003: 1 # retry count per task ID; reset on progress + T-ORCH-003: 1 # retry count per task ID; reset on progress artifacts_produced: - specs/auth-rework/scope.md - specs/auth-rework/research.md diff --git a/specs/goal-oriented-orchestrator-plugin/spec.md b/specs/goal-oriented-orchestrator-plugin/spec.md index 9d7288855..3d1afbf6c 100644 --- a/specs/goal-oriented-orchestrator-plugin/spec.md +++ b/specs/goal-oriented-orchestrator-plugin/spec.md @@ -1110,7 +1110,7 @@ This specification covers the behavioural contracts for the goal-oriented orches - **Side effects:** None (read-only script). - **Errors:** - - YAML parse error on a frontmatter block: emit a warning (not an error) naming the file; treat as no frontmatter; continue.

The orchestrator does not intercept slash commands. - - **Issue reference:** if the message matches the issue reference pattern (see pattern below), route to `scope-phase` with `IssueContent`. Fetch the issue before proceeding. - - **Free-text problem statement:** otherwise (non-empty message, no slash prefix, no issue reference), route to `scope-phase` with `ProblemStatement`. - - **Unrecognisable input:** if the message is empty or consists only of whitespace, display the welcome message (defined in design.md Part B) and wait for a new message. Do not enter the goal-loop. - - 2. **Issue reference regex pattern.** The orchestrator matches issue references using the following pattern (applied against the full message string): - ``` - Issue number only: \B#(\d+)\b - Full GitHub issue URL: https://github\.com/[^/\s]+/[^/\s]+/issues/(\d+) - ``` - - `\B#(\d+)\b` — matches `#NNN` where NNN is one or more digits, preceded by a non-word boundary (not alphanumeric or underscore), and followed by a word boundary. This prevents matching `abc#123` in a code snippet. - - The URL pattern captures the issue number from the path. The repository org/name is extracted from the URL path segments (positions 4 and 5 after splitting on `/`). - - If the message contains BOTH a slash command prefix and an issue reference (e.g., `/issue:tackle #501`), the slash command rule takes priority and the message is dispatched as a `/issue:tackle` command. The `/issue:tackle` command handler (SPEC-ORCH-002 item 3) then normalises to an issue reference. - - Only the first matching issue reference in the message is used. - - 3. **`/issue:tackle` normalisation.** When the user invokes `/issue:tackle #NNN` or `/issue:tackle <issue-url>`, the orchestrator: - - Extracts the issue number or URL from the command arguments. - - Treats this as equivalent to submitting that issue reference directly. - - Proceeds identically to the "Issue reference" routing case above. - - The user experience is indistinguishable from submitting the issue reference as a free-text message. - - 4. **workflow-state.md initialisation.** Before entering the scope phase, the orchestrator: - - Checks whether a `workflow-state.md` exists in `specs/<slug>/` with an in-progress goal_loop block. - - If found: displays the resume prompt (defined in design.md Part A Flow A10) and waits for user choice before proceeding. - - If not found: writes a new `workflow-state.md` with `goal_loop.current_phase: scope` and `goal_loop.hitl_state.pending: false` before invoking the scope phase. - - The feature slug is derived from the first substantive noun phrase of the problem statement or from `issue-<NNN>` for issue references. If the derived slug conflicts with an existing `specs/` directory, a 4-character lowercase hex suffix is appended (e.g., `auth-rework-a3f1`). The user is informed of the slug in the Gate 1 message. - -- **Pre-conditions:** The orchestrator is the active session agent (plugin settings.json active). - -- **Post-conditions:** - - `command-passthrough` route: no workflow-state changes; command executes through its normal handler. - - `scope-phase` route: `workflow-state.md` is initialised; scope phase begins. - -- **Side effects:** - - On issue reference: reads GitHub issue via GitHub MCP tool (read-only). - - On scope-phase route: creates `specs/<slug>/workflow-state.md` if not already present. - -- **Errors:** - - GitHub issue fetch fails: display "Could not fetch issue" error message (design.md Part A §Issue fetch failure) via inline message (not AskUserQuestion).

The orchestrator invokes the grill skill in its own execution context (not as a subagent Agent call). The grill skill's clarifying-question loop runs until EARS criteria are unambiguous or the maximum of 5 grill-rounds is reached. - 2. After the grill skill returns, the orchestrator writes `scope.md` (schema in SPEC-ORCH-012) to `specs/<slug>/scope.md`. - 3. The orchestrator writes `workflow-state.md` with `goal_loop.hitl_state: {gate: 1, pending: true}` and adds `specs/<slug>/scope.md` to `goal_loop.artifacts_produced`. - 4. The orchestrator calls `AskUserQuestion` with the Gate 1 prompt (formatted per design.md Part A §Gate 1). The prompt includes: gate header, acceptance criteria as a numbered list (the `criteria[].text` fields from `scope.md`), and the three options (A / E / X). - 5. **On response A (Approve):** The orchestrator updates `workflow-state.md` with `goal_loop.hitl_state.pending: false` and `goal_loop.current_phase: research`, then proceeds to the research wave (SPEC-ORCH-004). - 6. **On response E (Edit):** The orchestrator outputs the path `specs/<slug>/scope.md` and waits for the user to reply "done" (case-insensitive). On "done", the orchestrator re-reads `scope.md`, re-parses the criteria from the `## Acceptance criteria` section, updates `scope.md` frontmatter field `ears_count` to the new count, and re-presents Gate 1 with the updated criteria list. This cycle repeats until the user chooses A or X. - 7. **On response X (Abort):** The orchestrator updates `workflow-state.md` with `goal_loop.current_phase: aborted`. It outputs: "Session aborted. `specs/[slug]/scope.md` has been written for reference. No other artifacts were produced." The session ends; no further orchestrator actions are taken. - 8. **Grill skill zero-output handling:** If the grill skill returns zero criteria, the orchestrator writes any partial output to `scope.md`, then displays the "Scope extraction incomplete" error message (design.md Part A §Grill skill extraction failure) via inline message. Options offered: edit scope.md manually and reply "done", retry with a narrower description, or abort. This is not a Gate 1 call — it is a recovery path before Gate 1. - 9. **Maximum edit cycles:** There is no enforced limit on the number of times the user may cycle through the Edit path at Gate 1.

Do not repeat findings from - other researchers — focus on your assigned question." - - Return from each analyst: - findings: ResearchFinding[] (see data structures section) - OR empty output (treated as zero findings for this analyst) - ``` - -- **Behaviour:** - - **Researcher count heuristic (N determination):** - The orchestrator determines N by counting the number of distinct "surface dimensions" in the scope criteria list: - - 1–2 criteria, single area of change → N = 1 - - 3–4 criteria, or criteria that span two identifiable concern areas → N = 2 - - 5–7 criteria, or criteria spanning three concern areas → N = 3 - - 8–10 criteria, or criteria spanning four concern areas → N = 4 - - 11+ criteria, or criteria spanning five or more concern areas → N = 5 - - N is always clamped to the range [1, 5]. - - A "concern area" is identified by the orchestrator from the criterion texts: common areas include data model, API behaviour, security, performance, and UI/UX. The orchestrator assigns each criterion to its primary concern area; distinct areas drive the count. - - The determined N is written to `workflow-state.md` field `goal_loop.researcher_count` before any Agent calls are issued. - - **Question assignment:** - - Each analyst receives a distinct question targeting one concern area. - - No two analysts receive the same question. - - Questions are bounded (max 120 words) and derived from the scope criteria. The orchestrator must not include the full criteria text in the question — only the aspect relevant to that analyst's concern area. - - **Parallel dispatch:** - - The orchestrator issues all N Agent tool calls in a SINGLE orchestrator turn (parallel execution). - - The orchestrator emits the status banner `→ [research-wave] Dispatching [N] analyst agent(s)...` immediately before issuing the calls. - - The orchestrator waits for all N calls to complete before proceeding. - - **De-duplication algorithm:** - - After all analysts return, the orchestrator de-duplicates findings using the following rules: - 1. Two findings are considered duplicates if their heading sentences are semantically equivalent (same factual claim, possibly different phrasing) OR if their supporting detail overlaps by more than 60% of key claims. - 2. When a duplicate is detected, the finding from the analyst with the lower index (first dispatched) is retained; the duplicate is discarded. - 3. Attribution is preserved: the retained finding's `analyst_index` field records all analyst indices that surfaced the same finding (e.g., `analyst_index: [0, 2]`). - - The de-duplication step is performed in-context by the orchestrator (not by a subagent). - - **research.md write:** - - The orchestrator writes `specs/<slug>/research.md` with the merged, de-duplicated findings. - - Format: standard research.md header (matching existing `/spec:research` output format), followed by findings grouped by concern area, with attribution comments. - - Attribution format per finding: `<!-- sourced from analyst-[N] -->` HTML comment on the line preceding the finding heading. - - After writing, the orchestrator adds `specs/<slug>/research.md` to `workflow-state.md`'s `goal_loop.artifacts_produced`. - - **Zero-results handling:** - - If ALL analysts return empty output or findings that de-duplicate to zero items, the orchestrator displays the "Research wave returned no findings" inline message (design.md Part A §Research wave returns no findings) and proceeds to design synthesis with scope criteria only. - - This is not an AskUserQuestion gate call; the user is informed but not blocked. - - `research.md` is still written, with a body stating: `No findings were returned by the research wave. Design synthesis will use scope criteria only.` - - **Partial results:** - - If some analysts return findings and some return empty output, the non-empty results are used.

The orchestrator emits status banner `→ [design] Producing design document...` before dispatching the architect. - 2. Pre-flight check: both `specs/<slug>/scope.md` and `specs/<slug>/research.md` must exist and be non-empty. If either is absent or empty, surface the "Missing prerequisite" error (design.md Part A §Precondition check failure) and do not dispatch the architect. - 3. The orchestrator dispatches a SINGLE architect Agent call. If `SPECORATOR_HEAVY_MODEL` env var is set and non-empty, its value is passed as the `model` parameter of the Agent call. - 4. After the architect returns, the orchestrator verifies that `specs/<slug>/design.md` exists and is non-empty. If absent, display "Missing prerequisite" error with artifact = `design.md`. - 5. The orchestrator extracts an inline summary from `design.md` by reading the following sections: the first `## Key decisions` table (up to 3 rows), the first `## Components` table (up to 5 rows), and the first `## Risks` section (up to 3 items). If these sections are absent, the orchestrator uses any available summary content. - 6. The inline summary is truncated to at most: 3 architecture decision bullets, 5 component bullets, 3 risk bullets (as specified in design.md Part A Gate 2 §Design rationale). - 7. The orchestrator writes `workflow-state.md` with `goal_loop.current_phase: design`, `goal_loop.hitl_state: {gate: 2, pending: true}`, and adds `specs/<slug>/design.md` to `goal_loop.artifacts_produced`. - 8. The orchestrator calls `AskUserQuestion` with the Gate 2 prompt. - 9. **On response A (Approve):** Update `workflow-state.md` to `current_phase: plan`, `hitl_state.pending: false`. Proceed to plan phase (SPEC-ORCH-006). - 10. **On response E (Edit):** Output the path `specs/<slug>/design.md` and wait for "done". On "done", re-read `design.md`, re-extract the inline summary, and re-present Gate 2. - 11. **On response R (Reject):** The orchestrator issues a follow-up inline message asking: "Briefly describe what is wrong with this design." (not an AskUserQuestion call — a plain text prompt). The user replies with free text. The orchestrator records the rejection reason in `workflow-state.md` body under a `## Rejection notes` section (appended, not overwriting). The orchestrator updates `workflow-state.md` to `current_phase: research` and re-enters the research wave (SPEC-ORCH-004) with the rejection note appended to the scope context passed to analysts. - -- **Pre-conditions:** - - `scope.md` and `research.md` exist and are non-empty. - - Gate 1 has been approved. - -- **Post-conditions:** - - A: `design.md` exists; `workflow-state.md` reflects `current_phase: plan`. - - E: `design.md` is re-read; Gate 2 is re-presented. - - R: Rejection reason written to `workflow-state.md`; research wave re-entered. - -- **Side effects:** - - Writes/overwrites `specs/<slug>/design.md` (via architect subagent). - - Updates `workflow-state.md` multiple times (before dispatch, before Gate 2, on gate resolution). - -- **Errors:** - - `design.md` absent after architect returns: "Missing prerequisite — design.md" error message.

Orchestrator dispatches a SINGLE planner Agent call. - 4. After planner returns, orchestrator verifies `specs/<slug>/tasks.md` exists and is non-empty. - 5. **DAG validation and wave schedule derivation (Kahn's BFS):** - - Parse all task IDs from `tasks.md` (`T-<SLUG>-NNN` headings). - - Parse all `depends_on` lists. - - Validate: every task ID in any `depends_on` list must be present as a task heading in the same file. Unknown ID → error (see Errors below). - - Validate: no self-referential dependency (a task whose `depends_on` contains its own ID). - - Run Kahn's BFS topological sort: - - Compute in-degree for each task (count of tasks that list it as a predecessor). - - Initialise queue with tasks where in-degree = 0 (no dependencies). - - Process queue: assign each dequeued task to the current wave; decrement in-degree of successor tasks; enqueue any successor whose in-degree reaches 0. - - After processing, if any task has in-degree > 0, a cycle exists. - - If a cycle is detected: the orchestrator does not write the wave schedule. It displays an inline error message: "Circular dependency detected in tasks.md. Tasks involved: [list of task IDs with non-zero remaining in-degree]. Please open `specs/<slug>/tasks.md` and resolve the cycle, then reply 'done'." The orchestrator waits for "done" and re-runs validation. - - On successful sort: write the derived wave schedule to `workflow-state.md` `goal_loop.wave_schedule` (array of `{wave: number, task_ids: string[], status: 'pending'}`). - 6.

For each wave W in `workflow-state.md` `goal_loop.wave_schedule` with `status: 'pending'`: - a. Update `goal_loop.wave_schedule[W].status` to `'in-progress'` in `workflow-state.md`. - b. Emit `→ [wave-W] Dispatching [K] task agent(s)...`. - c. Issue K parallel Agent calls (one per task in the wave) in a SINGLE orchestrator turn. All calls specify `isolation: worktree`. - d. Wait for ALL K agents to return. - e. For each returned agent result: - - If `status: 'complete'`: record task as complete; stall_counters[task_id] = 0. - - If `status: 'cannot-proceed'` or `status: 'error'`: increment `stall_counters[task_id]` in `workflow-state.md`. If `stall_counters[task_id] >= 3`, invoke the stall gate (SPEC-ORCH-008) for that task. Otherwise, re-dispatch that task (same wave, this time only the failing task). - f. **Post-wave merge:** After all tasks in the wave are complete (not stalled or skipped), the orchestrator merges worktrees. The merge strategy is: for each worktree, apply its committed changes to the main working directory. If two agents in the same wave have modified the same file, this is a conflict (see conflict handling below). - g. Update `goal_loop.wave_schedule[W].status` to `'complete'` and emit `→ [wave-W] [K] task(s) merged.` - 2. Advance to wave W+1. If no more waves, proceed to review phase (SPEC-ORCH-009). - - **Model selection (REQ-ORCH-004):** If `SPECORATOR_HEAVY_MODEL` is set and non-empty, ALL dev subagent Agent calls include `model: process.env.SPECORATOR_HEAVY_MODEL`. If the value is not a recognised model identifier, the orchestrator falls back to the session default model and emits an inline warning: "SPECORATOR_HEAVY_MODEL value '[value]' is not a recognised model identifier. Using session default model." The warning does not block execution. - - **Worktree conflict handling:** If two agents in the same wave have modified the same file: - - The orchestrator surfaces an inline message: "Conflict in wave [W]: tasks [T-A] and [T-B] both modified `[file-path]`. Applying [T-A]'s changes first. If this is incorrect, open the file and correct it, then reply 'done'." - - The orchestrator applies the changes from the lower-indexed task (first dispatched) first. - - After applying: waits for user "done" reply before proceeding to the next wave. - - This is not an AskUserQuestion gate call — it is a recovery notice. - - **Skip semantics:** When a task is skipped via the stall gate: - - The task is marked `deferred` in `workflow-state.md`. No new field is introduced; `deferred` is tracked via a `deferred_tasks: string[]` list added to the `goal_loop` block. - - All tasks that have the skipped task ID in their `depends_on` list are also marked `deferred` (cascading). The cascade is computed transitively. - - Deferred tasks are excluded from all subsequent wave dispatches. - - Deferred tasks appear in `session-summary.md` under "Open follow-ups." - -- **Pre-conditions:** `tasks.md` exists and is non-empty; `workflow-state.md` `goal_loop.wave_schedule` is populated; all preceding waves are complete. - -- **Post-conditions:** All non-deferred tasks across all waves are complete; worktrees merged; `workflow-state.md` all wave statuses are `'complete'` or tasks are `deferred`. - -- **Side effects:** - - Creates isolated worktrees for each dev/qa subagent. - - Writes implementation changes to the working directory (via worktree merge). - - Updates `workflow-state.md` `goal_loop.wave_schedule`, `stall_counters`, and optionally `deferred_tasks`. - -- **Errors:** - - Worktree creation failure: surface error naming the task ID; offer retry or skip. - - All tasks in a wave are deferred: emit `→ [wave-W] All tasks deferred.

If `stall_counters[task_id] < 3`: the orchestrator re-dispatches the task immediately (no user interaction). The re-dispatch uses the same Agent call parameters as the original dispatch. - 5. If `stall_counters[task_id] == 3`: - - Orchestrator writes `workflow-state.md` with `goal_loop.hitl_state: {gate: 'stall', pending: true}`. - - Orchestrator calls `AskUserQuestion` with the stall gate prompt. - 6. **On response R (Retry):** Orchestrator resets `stall_counters[task_id] = 0` in `workflow-state.md`. Updates `hitl_state.pending: false`. Re-dispatches the task. If the stall recurs (counter reaches 3 again), the stall gate is presented again — no cap on number of user-initiated retries. - 7. **On response S (Skip):** Mark `task_id` and all transitively dependent tasks as `deferred` in `workflow-state.md` `goal_loop.deferred_tasks`. Update `hitl_state.pending: false`. Continue wave execution with remaining non-deferred tasks. - 8. **On response X (Abort):** Orchestrator writes a partial `session-summary.md` (see SPEC-ORCH-010 §Abort path).
