## What it does

This skill triages pull requests from external contributors, ignoring bots and authors listed under `## Trusted Authors` in `memory/watched-repos.md`. It targets a single PR like `owner/repo#N`, an entire repository, or all repositories tracked in the configuration file. Runs process up to 8 PRs per repository from the last 14 days.

The workflow queries the GitHub CLI to assess four strict rules: touched directories, YAML frontmatter validity, directory uniqueness, and size under 500 lines. When a diff exceeds 3000 lines, it inspects only the five largest files. Each evaluated PR receives an explicit verdict: ACCEPTED, NEEDS-CHANGES, DEFER, or OUT-OF-SCOPE.

A configured `gh` CLI session is required for API access and diff retrieval. Idempotency relies on `memory/triaged-prs.json` and recent `**Triage:**` comments, preventing duplicate verdicts on unchanged commits.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill pr-triage -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill pr-triage -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill pr-triage -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aeonfun/aeon pr-triage
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill pr-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aeonfun/aeon --path skills/pr-triage
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill pr-triage -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/aeonfun/aeon/tree/HEAD/skills/pr-triage/SKILL.md

## When to use it
- filter out pull requests from bots and trusted authors
- verify diff size and detect changes to protected system paths
- validate YAML frontmatter in modified `SKILL.md` files
- publish a first-touch verdict comment with next steps

## Example prompts
- Run triage on `aeonfun/aeon#143`
- Check open external pull requests for `aeonfun/aeon`
- Run pr-triage across all repos in `memory/watched-repos.md`

> **${var}** — PR scope. Accepts `owner/repo`, `owner/repo#N`, or empty (all watched repos). If empty, scans every repo in `memory/watched-repos.md`.

External PRs that sit unanswered look unwelcoming. This skill is the **first touch** for every external pull request — it reads the diff, applies a structured rubric, posts a comment with a verdict + rationale, and labels the PR so a human reviewer can pick it up with full context. It is not a substitute for `pr-review` (depth) or `auto-merge` (execution); it is the welcoming layer that runs before either of those decide whether to engage.

## What "external" means

Any PR whose author is **not** in the trusted set qualifies. The trusted set is, by precedence:

1. Logins ending in `[bot]` (`dependabot[bot]`, `renovate[bot]`, `github-actions[bot]`, …) — these route to `auto-merge` / `pr-review`.
2. The agent's own login: `aeonframework`, `aeonfun`, and any login under a `## Trusted Authors` heading in `memory/watched-repos.md` (same allowlist convention used by `auto-merge`).

Everything else is **external** and gets triaged.

## Config

`memory/watched-repos.md`:

```markdown
# Watched Repos
- aeonfun/aeon
- aeonfun/aeon-agent

## Trusted Authors
- alice
- bob
```

If the file is missing and `${var}` is empty, log `PR_TRIAGE_OK no-watched-repos` and exit.

---

Read `memory/MEMORY.md` for context.
Read `memory/triaged-prs.json` (if present; else treat as `{}`) — schema: `{"owner/repo": [{"n": 143, "sha": "abc123", "at": "2026-04-29", "verdict": "ACCEPTED"}, ...]}`. Used for idempotency keyed on (PR number, headRefOid).
Read the last 2 days of `memory/logs/` as a fallback dedup signal in case the JSON state file is missing.

## Steps

### 1. Resolve targets

- `${var}` matches `^[\w.-]+/[\w.-]+#\d+$` → single-PR mode: target that exact PR.
- `${var}` matches `^[\w.-]+/[\w.-]+$` → repo mode: scan all open PRs on that one repo.
- `${var}` is set but matches neither shape → abort with `pr-triage: invalid var — expected owner/repo or owner/repo#N` and exit.
- `${var}` is empty → fleet mode: read non-comment, non-blank `- ` lines from `memory/watched-repos.md` (everything **above** the `## Trusted Authors` heading).

### 2. Fetch candidate PRs

For each repo:

```bash
gh pr list -R owner/repo --state open --limit 25 \
  --json number,title,body,author,isDraft,labels,headRefOid,baseRefName,additions,deletions,files,createdAt,updatedAt,isCrossRepository \
  --search "created:>=$(date -u -d '14 days ago' +%Y-%m-%d)"
```

Per-run budget: **≤8 PRs per repo per run** (newest first; remainder logged as overflow).

In single-PR mode, fetch just the one PR:
```bash
gh pr view N -R owner/repo \
  --json number,title,body,author,isDraft,labels,headRefOid,baseRefName,additions,deletions,files,createdAt,updatedAt,isCrossRepository
```

### 3. Skip rules (record reason for each skip)
