| description | MANDATORY for every coding agent (Claude Code, Codex, or any other) — keep this repository's documentation in sync after any change to behavior, configuration, interfaces, events, schema, or features. Use automatically (without being asked) at the end of ANY change-set that adds or alters an env var, event type, hook behavior, session/agent state transition, API route or response shape, DB schema, WebSocket message, MCP tool, CLI command, or user-facing feature — and whenever the user asks to "update the docs / README / wiki / architecture". Knows the full doc surface (README + VN/CN/KO, ARCHITECTURE, root index.html, wiki + i18n, server/client READMEs, docs/*) and which docs each kind of change touches. |
Update Project Docs
This repository keeps an unusually large, multi-surface, multi-language doc set. Docs drift silently because a change often belongs in 6–10 files across 4 languages plus two HTML pages. This skill encodes which docs exist, which change-types touch which docs, and how to propagate consistently (including the wiki i18n + cache-bump dance).
Authoritative inventory with exact section anchors lives in references/doc-map.md — read it when deciding where a specific change lands. The repo rule .claude/rules/docs-markdown.md ("update all affected docs together") and .claude/rules/wiki-i18n.md are binding.
When to update (including without being asked)
Update docs in the same change-set (PR/commit) as the code, before claiming done — do not wait for the user to ask — whenever the change is observable from outside the module:
- New/changed env var → every env-var table +
.env.example.
- New event type (e.g. an
events.event_type value) → every event-type list/table.
- New/changed hook behavior or session/agent state transition → hook docs + every state-machine diagram.
- New/changed API route or response shape → API docs + route tables + OpenAPI.
- DB schema change (table/column/index) → database docs + ERD.
- New WebSocket message type → client/server WS docs.
- New MCP tool → MCP docs.
- New CLI command / script / renamed file referenced in docs → command lists + onboarding guides.
- New user-facing feature / page / background service → feature tables + landing + wiki + architecture.
Do NOT auto-update for: pure internal refactors with no observable/interface/config change, test-only changes, comment/typo fixes, or work the user explicitly scoped as "no docs". When unsure whether a change is observable, check the mapping below; if it touches any row, update.
Change → docs mapping
| Change type | Docs to update |
|---|
| Env var | README.md, README-VN.md, README-CN.md, README-KO.md (env tables), ARCHITECTURE.md (inline), server/README.md, wiki/index.html (env table) + wiki i18n, .env.example |
| Event type | README.md+VN+CN (hook-event table), ARCHITECTURE.md (Event types line), docs/PLUGINS.md, wiki/index.html + i18n, docs/DATABASE.md (if it enumerates types) |
| Hook behavior / state transition | docs/HOOKS.md, state-machine mermaid diagrams in README.md+VN+CN + server/README.md + docs/DATABASE.md + wiki/index.html, ARCHITECTURE.md (hooks.js row) |
| API route / response | docs/API.md, server/README.md (routes), ARCHITECTURE.md (routes row), server/openapi*.js (code) |
| DB schema | docs/DATABASE.md, ARCHITECTURE.md (ERD/schema) |
| WebSocket message | client/README.md (Event Types), server/README.md, wiki/index.html |
| MCP tool | mcp/README.md, docs/MCP.md |
| Feature / page / background service | README.md+VN+CN (feature table + data-flow list), ARCHITECTURE.md (module table), index.html (landing blurb), wiki/index.html + i18n, server/README.md or client/README.md |
| CLI command / script | README.md commands, / , / |
Procedure
- Classify the change against the table above. A change can hit multiple rows (a new feature with a new env var hits both).
- Write the canonical English version first — usually
README.md and/or ARCHITECTURE.md. Get the wording right there; it anchors everything else.
- Propagate to translations
README-VN.md, README-CN.md, and README-KO.md: mirror the SAME edits at the corresponding sections. Keep identifiers, env-var names, event names, and code in English; translate only prose. Render "Waiting" as Đang chờ (vi) / 等待中 (zh) / 대기 중 (ko). Match each file's existing terminology — read the neighboring lines first.
- Landing page
index.html: one concise marketing sentence in the most relevant existing feature card — light touch, no new sections.
- Wiki
wiki/index.html: add the detailed prose/table/diagram, then follow .claude/rules/wiki-i18n.md — add zh + vi entries for every new English string to wiki/i18n-content.js, then bump the cache: increment CACHE_NAME in wiki/sw.js and the i18n-content.js?v= query string in wiki/index.html. Skipping the cache bump means returning visitors never see the update.
- Area READMEs / docs/: update
server/README.md, client/README.md, and the relevant docs/*.md per the mapping.
- Diagrams: when a state transition changes, edit every mermaid
stateDiagram-v2 block that models it (they are duplicated across README/VN/CN/KO, server/README, docs/DATABASE, wiki). Keep transition labels consistent.
Verify (do not skip)
- Coverage: run
scripts/doc-coverage.sh <new-term> [...] (e.g. the new env var / event type / identifier) and confirm every doc the mapping flags shows a HIT. The matrix is advisory — not every term belongs in every file — but a flagged doc reading 0 is a miss to fix.
- Tables: markdown tables stay pipe-balanced (header column count == every row).
- Mermaid: each edited block still parses (valid
source --> target: label).
- i18n: every new wiki English string resolves to both
zh and vi; cache versions bumped.
- Format/tests: run
npm run format (or prettier --check on touched files); for any code touched, run the verification from CLAUDE.md (npm run test:server / test:client / mcp:typecheck).
- State exactly which docs were updated and which were intentionally skipped (with reason), mirroring the repo's verification policy.
Tips
- The fastest way to find where something already lives:
grep -n "<existing-neighbor-term>" <doc> (e.g. grep an adjacent env var to find the env table). references/doc-map.md lists the stable anchors per file.
- Parallelize translations + HTML across subagents when the change is large, but write the canonical English edit yourself first so the translations have a faithful source.
- One language/area per subagent keeps edits reviewable and tables un-corrupted.
