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 at the end of change-sets that alter an env var, event type, hook or state behavior, API, schema, WebSocket message, MCP tool, CLI command, or user-facing feature, and whenever the user asks to update documentation.

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 5 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`](references/doc-map.md) — read it when deciding where a specific change lands. The repo rules [`.claude/rules/docs-markdown.md`](../../rules/docs-markdown.md) ("update all affected docs together"), [`.claude/rules/wiki-i18n.md`](../../rules/wiki-i18n.md), and [`.claude/rules/i18n-parity.md`](../../rules/i18n-parity.md) are binding. Translation propagation — the mirrored READMEs, the wiki bundles, and the UI keys — is owned by the [`i18n-parity`](../i18n-parity/SKILL.md) skill; run it whenever this skill's mapping sends you into a localized file.

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-EN.md`, `README-CN.md`, `README-VN.md`, `README-KO.md`, `README-ES.md` (env tables), `ARCHITECTURE.md` (inline), `server/README.md`, `wiki/index.html` (env table) + wiki i18n, `.env.example` | | **Event type** | `README-EN.md`+CN+VN+KO+ES (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-EN.md`+CN+VN+KO+ES + `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-EN.md`+CN+VN+KO+ES (feature table + data-flow list), concise `README.md` only when the capability is headline-level, `ARCHITECTURE.md` (module table), `index.html` (landing blurb), `wiki/index.html` + i18n, `server/README.md` or `client/README.md` | | **CLI command / script** | `README-EN.md` commands, concise `README.md` only for primary entry points, `CLAUDE.md` / `AGENTS.md`, `INSTALL.md` / `SETUP.md` | | **New language** | Run the [`i18n-parity`](../i18n-parity/SKILL.md) skill and work through its [new-language checklist](../i18n-parity/references/new-language-checklist.md) — it covers `docs/I18N.md`, `client/src/i18n/**`, the switchers, `format.ts`, `README-<XX>.md`, and the full wiki bundle |

Procedure

1. **Classify** the change against the table above. A change can hit multiple rows (a new feature with a new env var hits both). 2. **Write the canonical full English version first** — usually `README-EN.md` and/or `ARCHITECTURE.md`. Get the wording right there; it anchors every full translation. Keep `README.md` as a concise English-only landing page. 3. **Propagate to translations** `README-CN.md`, `README-VN.md`, `README-KO.md`, and `README-ES.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 **等待中** (zh) / **Đang chờ** (vi) / **대기 중** (ko) / **En espera** (es). Match each file's existing terminology — read the neighboring lines first. The [`i18n-parity`](../i18n-parity/SKILL.md) skill owns this propagation and its glossary. 4. **Landing page** `index.html`: one concise marketing sentence in the most relevant existing feature card — light touch, no new sections. 5. **Wiki** `wiki/index.html`: add the detailed prose/table/diagram **at the length and in the position its neighbours already use** (see *Match the wiki's existing shape* below), then follow `.claude/rules/wiki-i18n.md` — add `zh` + `vi` + `ko` + `es` 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`.
