+Guidance for Claude (and other coding agents) working in this repo.
+
+## What this project is
+
+`verse-driven` ships a single Go binary (`scripture-mcp`) that serves canonical
+scripture passages — KJV Bible, 道德经, 心经, Quran — to coding agents via
+local stdio MCP, CLI, and hooks. Read `README.md` and `plan.md` first for the
+full picture; `docs/issues-backlog.md` is the work plan.
+
+## Working with scripture text — read this before touching packs
+
+Sacred-text bodies trip Anthropic's output content filter when echoed at
+volume in model output. A `400 invalid_request_error: Output blocked by
+content filtering policy` will kill the turn mid-tool-call.
+
+**Rule of thumb: scripture text should flow through scripts and files, never
+through the model's text output.**
+
+Practical guidance:
+
+- **Don't paste verse text into your responses.** Don't quote passages in
+  commit messages, PR bodies, code comments, or chat replies. Reference by
+  citation only (`John 3:16`, `道德经第十一章`).
+- **Don't echo verse text via Bash tool output.** Avoid `cat verses.jsonl`,
+  `head -100 some_pack.txt`, `grep '...' kjv.txt` printed inline. If you need
+  to inspect data, redirect to a file (`> /tmp/sample.txt`) and then read
+  only structural metadata (line counts, checksums, first-token, field
+  names) — not the text itself.
+- **Pack builders are write-only.** A build script downloads upstream text
+  and writes JSONL/JSON directly to `internal/packs/<name>/`. The model never
+  sees the body. The model only writes the script, runs it, and verifies
+  byte/verse counts and SHA-256 checksums.
+- **Tests assert by checksum, not by content.** `internal/packs/*_test.go`
+  should look up a known reference (e.g. `bible.kjv.john.3.16`) and compare
+  its `checksum_sha256` to a hard-coded expected hex digest, not its `Text`.
+  This keeps test files free of scripture text.
+- **Verifier scripts read & hash, never print.** `scripts/verify_quotes.py`
+  recomputes SHA-256 over each verse's text and compares to the stored
+  checksum. On mismatch it prints the verse `id` and the two hashes — not
+  the text.
+- **If you must spot-check a verse manually,** do it locally: build the
+  binary, run `scripture-mcp lookup "<ref>"`, eyeball the terminal. Don't
+  copy the output back into the conversation.
+
+If you hit the content filter mid-task, stop and refactor: move whatever was
+about to be quoted into a file write or a script, then continue.

+## Building & testing
+
+- `make build` → `bin/scripture-mcp`
+- `make test` → `go test ./...`
+- `make lint` → `go vet` + `staticcheck`
+- CI runs all three on push and PR; staticcheck failures block.
+
+## Conventions
+
+- Module path: `github.com/MiaoDX/verse-driven`. Go 1.24.
+- Verse IDs are dotted lowercase: `<tradition>.<work>.<book>.<chapter>.<verse>`,
+  e.g. `bible.kjv.john.3.16`, `dao.daodejing.11.1`, `sutra.heart-sutra.1`.
+- Every verse carries a SHA-256 over its `Text` bytes in `checksum_sha256`,
+  computed at pack-build time. Hashes are the integrity boundary between
+  upstream sources and the bundled binary.
+- Pack metadata (`metadata.json`) lives next to `verses.jsonl` and records
+  provider, license, attribution, source URL, and build date.
+- Branches: feature work goes on `claude-issue-<number>`; one PR per issue.
