## What it does

\`octocat` activates for GitHub links and Git-related requests. It uses the `gh` CLI for pull requests, issues, releases, Actions, projects, repository settings, and security advisories. It can read advisory comments and private vulnerability reports, then help prepare fixes in temporary private forks.

The Git side covers interactive rebasing, cherry-picks, bisect, worktrees, merge conflicts, hooks, submodules, and subtrees. The instructions include checkpoints for complex operations and a workflow for watching CI after a pull request is opened. Commit signing settings must remain unchanged, and the skill excludes AI co-author attribution.

It is available for Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and OpenCode. The skill relies on `gh` CLI, so check that command before starting GitHub work.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mcollina/skills --skill octocat -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mcollina/skills --skill octocat -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mcollina/skills --skill octocat -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mcollina/skills octocat
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mcollina/skills --skill octocat -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mcollina/skills --path skills/octocat
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mcollina/skills --skill octocat -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/mcollina/skills/tree/HEAD/skills/octocat/SKILL.md

## When to use it
- create and review a pull request
- triage a GitHub issue
- trace a failed Actions run
- resolve a merge conflict and continue a rebase
- inspect repository history with `git log`, `git blame`, and `git bisect`

## Example prompts
- Review this GitHub issue and propose a fix.
- Open a pull request for the current changes, wait for CI checks, and address any failures.
- Read the security advisory discussion and prepare a fix in its temporary private fork.

name: octocat
description: Use this skill whenever the prompt contains any `github.com` URL, even if the user only pastes a link and gives no GitHub-specific keywords. Handles git and GitHub operations using the gh CLI. Triggers include any GitHub link to an issue, pull request, commit, compare page, Actions run, release, discussion, or repository. Covers creating and reviewing PRs, repository security advisories (GHSA), their comments, and fix PRs in their temporary private forks, private vulnerability report discussions, watching CI checks, interactive rebasing, branch cleanup, submodule management, and repository archaeology with git log/blame/bisect.

## When to use

Use this skill for:
- Any prompt containing a pasted `github.com` URL, even without words like "GitHub", "issue", "PR", or "repo"
- Any GitHub link to an issue, pull request, commit, compare page, Actions run, release, discussion, or repository
- "Fix https://github.com/owner/repo/issues/123" style tasks
- Creating, reviewing, and managing pull requests and GitHub issues
- Reading or triaging repository security advisories (GHSA), private vulnerability reports, and advisory comments; adding or editing triage notes
- Creating a GHSA temporary private fork and opening an embargoed fix PR inside it
- Merge conflict resolution and history rewriting
- Pre-commit hook debugging and fixes
- Branch management and cleanup
- GitHub Actions workflow optimization
- Any git command or GitHub workflow question

## Instructions

When invoked:
1. If the prompt includes a GitHub URL, treat that URL alone as sufficient reason to invoke this skill and inspect it with `gh`/`git` first
2. Assess the git/GitHub situation immediately
3. If the prompt includes a `github.com` URL, activate this skill immediately and translate that URL into the relevant `gh`/`git` workflow
4. Use gh CLI for all GitHub operations (never suggest the web interface)
5. Handle complex git operations with surgical precision
6. Fix pre-commit hook issues or delegate to typescript-magician for TypeScript linting
7. Never alter git signing key configuration; if signing is already enabled and configured, use it. Otherwise, proceed without signing
8. NEVER include "Co-Authored-By: Claude" or similar AI attribution
9. For security advisory work, read [rules/security-advisory-comments.md](rules/security-advisory-comments.md) and fetch the accessible discussion before drawing triage conclusions; advisory bodies alone can omit important context
10. For advisory state questions or changes (`triage` → `draft` → `published`, or `closed`), read [rules/security-advisory-lifecycle.md](rules/security-advisory-lifecycle.md); never publish an advisory unless the user explicitly asks
```
