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 — read it when deciding where a specific change lands. The repo rules .claude/rules/docs-markdown.md ("update all affected docs together"), .claude/rules/wiki-i18n.md, and .claude/rules/i18n-parity.md are binding. Translation propagation — the mirrored READMEs, the wiki bundles, and the UI keys — is owned by the i18n-parity 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.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.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.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.md+CN+VN+KO+ES (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, CLAUDE.md / AGENTS.md, INSTALL.md / SETUP.md
New language	Run the i18n-parity skill and work through its new-language checklist — 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 English version first — usually README.md and/or ARCHITECTURE.md. Get the wording right there; it anchors everything else.
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 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. Skipping the cache bump means returning visitors never see the update.
6. Area READMEs / docs/: update server/README.md, client/README.md, and the relevant docs/*.md per the mapping.
7. Diagrams: when a state transition changes, edit every mermaid stateDiagram-v2 block that models it (they are duplicated across README/CN/VN/KO/ES, server/README, docs/DATABASE, wiki). Keep transition labels consistent.

Match the wiki's existing shape

The wiki is a designed page, not a changelog: several of its blocks live in fixed-size boxes. A block written at 2–3x the length of its neighbours breaks the layout, so measure before you write, and copy the pattern you find.

• Feature carousel cards (#feature-carousel .feature-card) share one fixed-height box. All 39 of them are a single <p>; the group runs 209–628 characters with a ~494 median, so write to roughly 450–550 characters (~65–80 words) — one paragraph, no lists, no sub-headings, no exhaustive enumeration of every keybinding and edge case. Say what the feature is and the two or three things that make it distinctive; the depth belongs in the feature's own section further down the page.
• Screenshot captions (.screenshot-caption) run ~150–300 characters: the emoji, the bolded screen name, an em dash, one dense sentence.
• Card order is editorial, not chronological. A new feature does NOT go first. Insert it where it belongs by importance among the existing cards — a newly shipped convenience feature belongs in the middle or later half of the carousel, not ahead of the dashboard, board, and session cards.
• Deep, unabridged prose (full keyboard maps, degradation behaviour, group-by- group breakdowns) belongs in a normal <section> with h3 + <ul>, never crammed into a card or caption.
• Run .claude/skills/update-project-docs/scripts/wiki-block-lengths.sh and confirm your block sits inside the group's budget before finishing.
• Changing wiki CSS? Verify it in a browser that ran script.js (see .claude/rules/wiki-i18n.md) — the scroll-reveal pass adds classes at runtime, so a :not([class]) selector that looks right in the file and in jsdom can apply to nothing on the live page.
• The same rule of thumb applies everywhere on the page: before adding a block of any kind, read the two blocks around it and match their length, tone, markup, and heading depth. Do not invent a new pattern for one entry.

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 zh, vi, ko, and es; cache versions bumped — CACHE_NAME in wiki/sw.js plus the ?v= query strings, which must match between wiki/index.html and the service-worker PRECACHE list (it matches on the full URL, query included, so a stale entry is simply never served).
• Wiki block sizing: .claude/skills/update-project-docs/scripts/wiki-block-lengths.sh exits 0 — no carousel card or caption is an outlier, and any new card is placed by importance rather than dropped at the front.
• 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.
