README UPDATER

MODES

First word of $ARGUMENTS determines mode. CREATE takes precedence if README.md missing.

• CREATE — README.md doesn't exist → build from scratch
• SYNC — first word is exactly sync → silent updates, no stop
• AUDIT — anything else (empty, description, "audit") → full diff + mandatory stop

DOCKER DETECTION (run in all modes before writing)

Docker relevant if: Dockerfile or docker-compose.yml present, or CLAUDE.md mentions deploy/service/API/server/Docker, or project is web app/API/backend/SaaS, or has DB/Redis/Kafka dep. Docker NOT relevant if: library, CLI (no server), mobile app, driver/plugin. Store as DOCKER_RELEVANT = true/false.

---

CREATE MODE

Sources (in order): CLAUDE.md, folder structure (find . -not -path '*/.git/*' -not -path '*/node_modules/*' ... | head -80), package manifest, .env.example, Dockerfile/compose if present.

Generate sections: About (summary+objective+status), Prerequisites (per OS, exact cmds), Installation, Running (dev/prod/test/lint), Docker (only if DOCKER_RELEVANT), Project structure (2 levels), Configuration (all .env.example vars), Contributing (branch → test → commit → PR).

Rules: exact runnable commands only, derive from CLAUDE.md, no placeholders.

Output: 📄 README created — <N sections> [Docker: included/N/A]. No stop.

---

SYNC MODE

Read: README.md, CLAUDE.md, git log (last 20), folder structure, manifests.

Apply only clear factual mismatches (no prose rewrites, no speculation, no stops):

• Changed commands in CLAUDE.md not in README
• New .env.example vars undocumented
• Changed folder structure
• Version bumps in manifests
• Docker section added/removed if DOCKER_RELEVANT changed
• Add ## Recent changes if 5+ commits since last README update and no changelog

Output: 📄 README synced — <N changes / "no changes needed"> [Docker: <status>]

---

AUDIT MODE

Phase 1 — Read

README.md, CLAUDE.md, git log --oneline -50, git diff HEAD~20..HEAD --stat, folder structure, manifest, .env.example, Dockerfile/compose if present.

Phase 2 — Status per section

✅ current | 📝 update | ➕ missing | ❌ remove

Check: About still accurate, prereqs versions, install/run cmds, Docker section vs DOCKER_RELEVANT, structure vs reality, all .env vars documented.

Phase 3 — Report + MANDATORY STOP

README AUDIT
LAST COMMIT : <hash — msg>
DOCKER      : relevant ✅/❌ — section present/missing/N/A
SUMMARY     : ✅<n> 📝<n> ➕<n> ❌<n>
DETAIL      : <per-section findings>
Proceed? (yes / select sections / cancel)

Phase 4 — Apply (after confirmation)

Surgical edits only. Preserve structure and tone. 📝 replace, ➕ insert, ❌ remove or mark deprecated.

Phase 5 — Verify

Re-read. No broken markdown. Commands consistent with CLAUDE.md.

Output: 📄 README updated — <summary>
