![Claude GitHub Webhook brain factory - AI brain connected to GitHub octocat via assembly line of Docker containers](./assets/brain_factory.png)

Deploy Claude Code as a fully autonomous GitHub bot. Create your own bot account, mention it in any issue or PR, and watch AI-powered development happen end-to-end. Claude can implement complete features, review code, merge PRs, wait for CI builds, and run for hours autonomously until tasks are completed. Production-ready microservice with container isolation, automated workflows, and intelligent project management. 

## What This Does

```bash
# In any GitHub issue or PR (using your configured bot account):
@YourBotName implement user authentication with OAuth
@YourBotName review this PR for security vulnerabilities  
@YourBotName fix the failing CI tests and merge when ready
@YourBotName refactor the database layer for better performance
```

Claude autonomously handles complete development workflows. It analyzes your entire repository, implements features from scratch, conducts thorough code reviews, manages pull requests, monitors CI/CD pipelines, and responds to automated feedback - all without human intervention. No context switching. No manual oversight required. Just seamless autonomous development where you work.

## 🚀 Quick Start

**Follow our [10-minute Quick Start Guide](./QUICKSTART.md)** to get Claude responding to your GitHub issues using Cloudflare Tunnel - no domain or complex setup required!

```bash
# 1. Clone and configure
git clone https://github.com/claude-did-this/claude-hub.git
cd claude-hub
cp .env.quickstart .env
nano .env  # Add your GitHub token and bot details

# 2. Authenticate Claude (uses your Claude.ai Max subscription)
./scripts/setup/setup-claude-interactive.sh

# 3. Start the service
docker compose up -d

# 4. Create a tunnel (see quickstart guide for details)
cloudflared tunnel --url http://localhost:3002
```

That's it! Your bot is ready to use. See the **[complete quickstart guide](./QUICKSTART.md)** for detailed instructions and webhook setup.

## Bot Account Setup

**Current Setup**: You need to create your own GitHub bot account:

1. **Create a dedicated GitHub account** for your bot (e.g., `MyProjectBot`)
2. **Generate a Personal Access Token** from the bot account with repository permissions
3. **Configure the bot username** in your environment variables
4. **Add the bot account** as a collaborator to your repositories

**Future Release**: We plan to release this as a GitHub App that provides a universal bot account, eliminating the need for individual bot setup while maintaining the same functionality for self-hosted instances.

## Production Deployment

### 1. Environment Configuration

```bash
# Core settings  
BOT_USERNAME=YourBotName              # GitHub bot account username (create your own bot account)
GITHUB_WEBHOOK_SECRET=<generated>     # Webhook validation
GITHUB_TOKEN=<fine-grained-pat>       # Repository access (PAT from your bot account)

# Claude Authentication - Choose ONE method:

# Option 1: Setup Container (Personal/Development)
# Use existing Claude Max subscription (5x or 20x plans)
# See docs/setup-container-guide.md for setup

# Option 2: Direct API Key (Production/Team)
ANTHROPIC_API_KEY=sk-ant-your-api-key

AUTHORIZED_USERS=user1,user2,user3    # Allowed GitHub usernames
CLAUDE_API_AUTH_REQUIRED=1            # Enable API authentication
```

## Authentication Methods

### Setup Container (Personal/Development)
Use your existing Claude Max subscription for automation instead of pay-per-use API fees:

```bash
# 1. Run interactive authentication setup
./scripts/setup/setup-claude-interactive.sh

# 2. In container: authenticate with your subscription
claude --dangerously-skip-permissions  # Follow authentication flow
exit                                    # Save authentication

# 3. Use captured authentication  
cp -r ${CLAUDE_HUB_DIR:-~/.claude-hub}/* ~/.claude/
```

**Prerequisites**: Claude Max subscription (5x or 20x plans). Claude Pro does not include Claude Code access.  
**Details**: [Setup Container Guide](./docs/setup-container-guide.md)

AWS_SECRET_ACCESS_KEY=xxx
```

## Advanced Usage

### Direct API Access

Create async Claude sessions via the webhook API:

```bash
# Create a new session
curl -X POST http://localhost:3002/api/webhooks/claude \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-webhook-secret" \
  -d '{
    "type": "session.create",
    "session": {
      "type": "implementation",
      "project": {
        "repository": "owner/repo",
        "requirements": "Analyze security vulnerabilities"
      }
    }
  }'

# Check session status
curl -X POST http://localhost:3002/api/webhooks/claude \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-webhook-secret" \
  -d '{
    "type": "session.get",
    "sessionId": "session-id-from-create"
  }'
```

### CLI Tool

```bash
# Basic usage
./cli/claude-webhook myrepo "Review the authentication flow"

# PR review
./cli/claude-webhook owner/repo "Review this PR" -p -b feature-branch

# Specific issue
./cli/claude-webhook myrepo "Fix this bug" -i 42
```

### Container Execution Modes

Different operations use tailored security profiles for autonomous execution:

- **Auto-tagging**: Minimal permissions (Read + GitHub tools only)
- **PR Reviews**: Standard permissions (full tool access with automated merge capabilities)
- **Feature Development**: Full development permissions (code editing, testing, CI monitoring)
- **Long-running Tasks**: Extended container lifetime with checkpoint/resume functionality
- **Custom Commands**: Configurable via `--allowedTools` flag

## Architecture Deep Dive

### Autonomous Request Flow

```
GitHub Event → Webhook Endpoint → Signature Verification
     ↓                                      ↓
Container Spawn ← Command Parser ← Event Processor
     ↓
Claude Analysis → Feature Implementation → Testing & CI
     ↓                     ↓                    ↓
GitHub API ← Code Review ← PR Management ← Build Monitoring
     ↓
Autonomous Merge/Deploy → Task Completion
```

### Autonomous Container Lifecycle

1. **Spawn**: New Docker container per request with extended lifetime for long tasks
2. **Clone**: Repository fetched (or cache hit) with full development setup
3. **Execute**: Claude implements features, runs tests, monitors CI, handles feedback autonomously
4. **Iterate**: Continuous development cycle until task completion
5. **Deploy**: Results pushed, PRs merged, tasks marked complete
6. **Cleanup**: Container destroyed after successful task completion

### Security Layers

- **Network**: Webhook signature validation
- **Authentication**: GitHub user allowlist
- **Authorization**: Fine-grained token permissions
- **Execution**: Container isolation
- **Tools**: Operation-specific allowlists

## Performance Tuning

### Repository Caching

```bash
REPO_CACHE_DIR=/cache/repos
REPO_CACHE_MAX_AGE_MS=3600000    # 1 hour
```

### Container Optimization

```bash
CONTAINER_LIFETIME_MS=7200000     # 2 hour timeout
CLAUDE_CONTAINER_IMAGE=claudecode:latest
```

### CI/CD Pipeline

- Parallel Jest test execution
- Docker layer caching
- Conditional image builds
- Self-hosted runners for heavy operations
