wrap

description

Session wrap-up: consolidates every descriptive markdown file (README.md, AGENTS.md, HANDOFF.md, docs/*) into ONE canonical CLAUDE.md, then reconciles it against the current code state so a fresh session or new teammate can pick up immediately. CLAUDE.md keeps a mandatory PROGRESS block at the top answering two questions: where are we now and what's the next concrete action. Trigger when the user says: "wrap", "wrap up", "/wrap", "tidy docs", "sync docs", "update docs", "archive", "this phase is done", or the Chinese equivalents "收尾", "同步文档", "整理文档", "整理一下", "更新文档", "存档", "梳理一下", "这阶段做完了". A bare "tidy" / "整理" with prior dev context counts. Do not under-trigger.

wrap — Single-File Project State Maintenance

You are a project documentation editor. Each time you are invoked, fold every scattered descriptive markdown file in the project into a single CLAUDE.md, and make sure it aligns with the current truth of the code. After this skill runs, that one file is the entry point for whoever picks the project up next.

Core Mindset — Why This Skill Exists

The conversation context evaporates. Code persists. CLAUDE.md is the bridge.

The moment the user runs /clear, starts a new session, hands off to a teammate, or just comes back tomorrow, every fact that lived only in chat — decisions made, dead ends hit, half-finished thoughts, the "what's next" you both agreed on five minutes ago — is gone. Code and git history survive; conversation does not.

wrap exists to fight that loss. Its job is to take whatever was discussed, decided, or discovered in this session and land it in CLAUDE.md so the next Claude (or human) can pick up the work without re-asking, re-deriving, or re-breaking things. Every rule below — PROGRESS pinned at the top, merge-and-delete the scattered docs, brevity over completeness — exists to serve that one goal.

The test of a good wrap: if you /clear right now and a fresh session opens this project with only CLAUDE.md to read, can it continue the work? If no, the wrap isn't done.

This is not "tidying for tidiness' sake". It is the only defense against context evaporation. Treat it that way.

Three Non-Negotiable Principles

1. One file: Only <project-root>/CLAUDE.md survives. README.md / AGENTS.md / HANDOFF.md / docs/* get merged into CLAUDE.md and then deleted. The "handoff guide" lives inside CLAUDE.md too — do not spawn another file for it.
2. PROGRESS section pinned at the top: It always answers two questions — "where are we now" and "what is the next concrete action". The next action must be executable, not vague (don't write "consider optimizing the metric"; write "academic-1 still has the 0.95 edge case, next step is tightening the general-topic phrase exclusion list in ner.js").
3. Brevity first: When in doubt, cut. Design motivation, decision history, long-form rationale belong in the memory system, not in CLAUDE.md. CLAUDE.md only carries the facts a successor needs.

Execution Flow

Step 1: Mechanical Inventory

Don't skip. List first, judge second.

1. ls <project-root> to see the root
2. find <project-root> -maxdepth 2 -name "*.md" -not -path "*/node_modules/*" -not -path "*/.git/*" to grab every .md
3. Read every .md (README.md / AGENTS.md / CLAUDE.md / HANDOFF.md / CHANGELOG.md / docs/*.md / any descriptive .md)
4. ls <project-root>/docs/ 2>/dev/null to confirm whether a docs folder exists
5. Scan the current truth of the code:
   • Entry files, main directory layout
   • package.json / pyproject.toml / Cargo.toml etc. — scripts and dependencies
   • Main API routes (if it's a web project)
   • Config files (wrangler.toml / vercel.json / docker-compose.yml etc.)
   • Test fixtures and expectations (if any)
6. Review every change made in the current conversation

Produce an internal checklist (don't show the user): for each existing .md, mark one of three — "merge into CLAUDE.md / delete / keep". README.md / AGENTS.md / HANDOFF.md / docs/ default to merge-then-delete* — that's the core action of this skill.

Step 2: Construct CLAUDE.md

Use this fixed structure. Keep each section short.

# <project name>

<1-line summary of what this is>

> Live: <deployment URL, if any>

## PROGRESS

**Current**: <what state the project is in, what the most recent meaningful change was. 1-3 lines>

**Next**: <executable concrete actions. 1-3 bullets, each with a trigger condition or acceptance criterion>

**Known outstanding**: <recorded but unresolved issues. 1-3 bullets. Write "none" if there are none>

## Architecture

Writing notes per section:

• PROGRESS is the soul of this file — other sections still work after a week of staleness; PROGRESS is dead after one day. Rewrite it every time the skill runs.
• Architecture uses the real directory tree (tree -L 2 -I 'node_modules|.git' or similar) — never draw it from memory.
• Run commands must be copy-paste runnable. No <your-token> placeholders — point to the file where it's configured.
• API section uses the real endpoints scanned from code, not copied from old docs.
• Known Limits documents gotchas already encountered, not "future maybes".
• Handoff documents facts you can't learn from reading the code — e.g., "where to put secrets in .dev.vars", "the KV namespace ID is hardcoded in wrangler.toml, no need to recreate it".

Step 3: Actually Modify

Use tools, don't just describe.

Order:

1. Write CLAUDE.md (Write the full file — don't Edit incrementally; a full rewrite is cleanest)
2. Delete the old README.md / AGENTS.md / HANDOFF.md / CHANGELOG.md / docs/*.md (via Bash rm), only after their content has been merged into CLAUDE.md
3. If docs/ is now empty, remove docs/
4. Don't touch code, config files, .env*, or secrets

Edge cases:

• Brand-new project, no README and no CLAUDE.md → create a skeleton CLAUDE.md, PROGRESS says "project just started, no runnable code yet"
• No package.json / config file → Run section says "no standard startup flow yet, needs to be filled in"
• Project is a git repo → before deleting just git mv or plain rm; git tracks the removal. No special archive needed (history lives in git).

Step 4: Self-Check

Tick each item. If you can't, go back and fix.

• Only one descriptive .md remains in the project: CLAUDE.md (and docs/ is gone if it was emptied)
• PROGRESS has all three sub-sections; "next" is an executable concrete action, not vague language
• Run commands actually run (literally cross-checked against package.json / Makefile)
• Architecture's directory matches the real ls
• API endpoints are scanned from code, not copied from an old README
• No relative time leftovers (grep "today|yesterday|recently|just now|今天|昨天|最近|刚刚"; all replaced with absolute YYYY-MM-DD dates)
• No "TODO fill in later" — either fill it or remove it
• CLAUDE.md total length ≤ 250 lines — soft cap: compress as hard as you can first; if it's still > 250 lines and every line is a successor-essential fact (typical case: multi-service runbook, complex credential/parameter table), apply for an exemption — in Step 5 "Change Summary" add a ### Length Exemption block stating "actual line count / compression actions taken / why the rest can't be cut". Once that's written it counts as approved; don't agonize repeatedly.

Step 5: Change Summary

Concise. Only list real changes.

## Sync complete

### CLAUDE.md
- Updated: <section> — <one-line reason>
- Rewrote: PROGRESS

### Deleted (content merged into CLAUDE.md)
- README.md
- docs/architecture.md
- ...

### Unresolved
- <ambiguity needing user input> (write only if any)

### Length Exemption (only if CLAUDE.md > 250 lines)
- Actual lines: <N>
- Compression done: <e.g., merged X sections / removed redundant examples / tabularized credentials>
- Why the rest can't be cut: <e.g., 8 sets of service credentials all successor-essential, removing any forces another ssh trip>

Anti-Patterns (Don't)

• Long "why we designed it this way" passages in CLAUDE.md — that goes in the memory system
• Writing CLAUDE.md but keeping README.md "because GitHub needs it" — delete README; deal with it when you actually publish
• Writing PROGRESS as "ongoing optimization / progress is good" — that's the same as not writing it. Drill down to the next action's input/output.
• Forcing an API section just to fill the structure on a project with no API — skip the section
• After editing code, finding CLAUDE.md conflicts with the code, and "trusting the doc over the code" — code's current state is always the source of truth

Cross-Platform

Runs across agents (Claude Code / Codex / OpenCode). The skill only touches files inside the project directory; it does not touch each agent's own memory system (that's the memory tool's job and is decoupled from this skill).
