## What it does

The skill walks the agent through setup in order. First it checks whether `gh` is authenticated and whether git has `user.name` and `user.email`. If both are set, it says GitHub is already configured and jumps ahead. Otherwise it runs `gh auth login` and asks which name and email should appear on commits Cyrus makes.

Part B is optional. The agent builds a GitHub App manifest, serves a small HTML form locally and POSTs the manifest to GitHub so the app receives webhooks for pull request comments and reviews. That unlocks @mention replies, automated rebases and merges, and auto-fixing on CI failures, which the skill lists as coming soon.

One rule is non-negotiable: never touch `~/.cyrus/.env` or anything under `~/.cyrus/` with `Read`, `Edit` or `Write`. Secrets stay out of the conversation and are handled with `Bash` commands like `grep` and `printf >>`. Webhook setup also needs `CYRUS_BASE_URL` already present in that env file, otherwise the step stops. Worth knowing before you pick a bot name: GitHub autocomplete only suggests real user accounts, so a matching username has to exist for @mentions to autocomplete.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-github -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-github -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-github -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cyrusagents/cyrus cyrus-setup-github
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-github -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cyrusagents/cyrus --path skills/cyrus-setup-github
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-github -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/cyrusagents/cyrus/tree/HEAD/skills/cyrus-setup-github/SKILL.md

## When to use it
- authenticate `gh` CLI without guessing at errors
- set the commit identity Cyrus uses
- create a GitHub App with the right permissions and events
- hook up webhooks so the agent sees PR comments
- keep secrets out of the chat context

## Example prompts
- set up GitHub for Cyrus
- check whether gh is authenticated and git is configured
- enable @mentions in pull request comments

name: cyrus-setup-github
description: Configure GitHub for Cyrus — gh CLI login and git config for PRs, with optional webhook setup to enable @mention responses in PR comments, automated rebases and merges, and auto-fixing based on CI failures (coming soon).

**CRITICAL: Never use `Read`, `Edit`, or `Write` tools on `~/.cyrus/.env` or any file inside `~/.cyrus/`. Use only `Bash` commands (`grep`, `printf >>`, etc.) to interact with env files — secrets must never be read into the conversation context.**

# Setup GitHub

Configures GitHub CLI and git so Cyrus can create branches, commits, and pull requests. Optionally creates a GitHub App so Cyrus can receive and respond to @mentions in PR comments and reviews, automate rebases and merges, and auto-fix based on CI failures (coming soon).

---

## Part A: GitHub CLI + Git Config (Outbound)

### Step 1: Check Existing Configuration

Check if `gh` is already authenticated:

```bash
gh auth status 2>&1
```

If authenticated, check git config:

```bash
git config --global user.name
git config --global user.email
```

If both `gh` auth and git config are set, inform the user:

> GitHub is already configured. Skipping to webhook setup.

Skip to Part B.

### Step 2: Authenticate GitHub CLI

If `gh` is not authenticated:

```bash
gh auth login
```

This opens an interactive browser flow. Let the user complete it.

After completion, verify:

```bash
gh auth status
```

### Step 3: Configure Git Identity

If git user name or email are not set, ask the user for their preferred values:

> **What name should appear on commits made by Cyrus?**
> (e.g., your name, or "Cyrus Bot")

> **What email should appear on commits?**
> (e.g., your email, or a noreply address)

Then set them:

```bash
git config --global user.name "<name>"
git config --global user.email "<email>"
```

### Step 4: Verify

```bash
gh auth status
git config --global user.name
git config --global user.email
```

---

## Part B: GitHub App + Webhooks (Inbound — Optional)

Ask the user:

> **Do you want Cyrus to respond to GitHub @mentions in PR comments and reviews?**
>
> - **Yes — enable @mentions**: Creates a GitHub App so Cyrus can receive PR comments and reviews via webhooks, respond when @mentioned, and act on "changes requested" reviews.
> - **No — PRs only**: Cyrus will create branches, commits, and PRs but won't respond to comments.

If **No** → skip to Completion.

### Step 5: Check Existing Webhook Config

```bash
grep -c '^GITHUB_WEBHOOK_SECRET=.' ~/.cyrus/.env 2>/dev/null
grep -c '^GITHUB_APP_ID=.' ~/.cyrus/.env 2>/dev/null
````
