## What it does

re0-merge sets out a review process for external pull requests. It checks whether a contribution fits the project thesis, calls for a fresh read of the change, and asks reviewers to prove an already submitted fix with a throwaway regression case rather than rewrite it.

When a PR is accepted, the skill calls for approval before merging and a `land/pr-<n>` branch. Contributor commits retain their authorship, while maintainer edits go into separate commits. Once the release containing the work is confirmed, the PR is closed with a comment that gives credit and explains any rename or reframing.

New skills need a suitable name, correct invocation mode and registration in `plugin.json`, README indexes, the `re0-upgrade` catalog and `scripts/catalog.cjs`. This is deliberately strict: additive work starts from a decline unless it shows why the project is worse without it. Installed `shower`, `re0-git` and `re0-release` skills are used when available; their steps are otherwise done manually.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-merge -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/re0-merge/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/re0-merge/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-merge -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/re0-merge/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-merge -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/re0-merge/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install LilMGenius/paperthin re0-merge
```

2. **Manually: put the files in place**
- File: `.github/skills/re0-merge/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-merge -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/LilMGenius/paperthin --path skills/depth/re0-merge
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/re0-merge/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-merge -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/LilMGenius/paperthin/tree/HEAD/skills/depth/re0-merge/SKILL.md

## When to use it
- review a PR against the project thesis
- retain contributor authorship in Git history
- separate maintainer edits into their own commits
- register a new skill across project catalogs
- close an accepted PR with credit and context

## Example prompts
- Review this pull request with re0-merge and decide whether it fills a real gap.
- Land the accepted changes on `land/pr-<n>`, preserving the contributor's authorship.
- Write the closing PR comment that credits the author and explains the rename.

description: "Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the author."
---

Land a contribution fairly: credit preserved, the maintainer's changes legible, accepted on the record.

## Goal

A contribution is a gift with a permanent carrying cost, and a review either honors both or fails one. `re0-merge` walks whoever reviews — any collaborator or maintainer, not just the author — through accepting a pull request the way this suite does: judged against the thesis, landed with the author's authorship intact, the maintainer's own edits kept as separate commits, and closed with an approval and a credit rather than a silent rejection.

## Workflow

1. **Gate before landing.** An additive contribution is declined by default; the burden is on the addition to show the suite is worse without it, not on you to justify a no. Judge each PR alone, never as a batch: a bug-fix subtracts a defect and is the easy yes; new tooling earns a place only if it mechanizes a rule already enforced by hand; a new skill lands only if it closes a real gap no existing one covers. A well-reasoned decline is a shipped outcome, not a failure.
2. **Cold-read it first.** Read the contribution end to end with fresh eyes (a `shower` pass when installed) before deciding; a name or claim that reads clean to its author may not to a stranger.
3. **Verify, do not re-fix.** Where the author already pushed a fix, prove it with a throwaway regression case rather than rewriting it; the credit for the fix is theirs.
4. **Approve as you accept, then land on a `land/pr-<n>` branch** (a range only for a genuine multi-PR batch). Submit the approving review the moment you decide to accept, before the land — it is a verdict on the contributor's code, not a receipt for a release, and giving it now (not bundled with the later close) is what keeps a closed-not-merged PR reading as accepted. Then accept each contributor commit with its authorship preserved (you become the committer; clean the message with `re0-git`), add every maintainer change as its own separate commit so the credit split stays legible, and fast-forward into `main`.
```
