- **Automatic PR Analysis**: Responds to GitHub pull request webhooks instantly
- **AI-Powered Reviews**: Uses Anthropic's Claude Haiku 4.5 for intelligent code analysis and typo detection
- **Secure Integration**: Webhook signature verification for security
- **Smart File Filtering**: Reviews code files and markdown files for typos, skips other documentation and config files
  - **Pull requests**: Read and write (required to post review comments)
**Anthropic API Key**: Get your API key from [Anthropic Console](https://console.anthropic.com/)
### 2. Configure Environment Variables
In Val Town, set these environment variables:
- `GITHUB_TOKEN`: Your GitHub personal access token
- `ANTHROPIC_API_KEY`: Your Anthropic API key  
- `WEBHOOK_SECRET`: A random secret string (generate with: `openssl rand -hex 32`)
- **Clear Descriptions**: Add good PR descriptions to help the AI understand context
- **Test First**: Use the debug endpoints to verify your setup before going live
- **Monitor Usage**: Keep an eye on your Anthropic API usage for cost management
- **Apply Suggestions**: Use GitHub's "Apply suggestion" button for one-click fixes
- **File Size**: Large files are truncated to 2000 characters for analysis
- **File Types**: Reviews code files for quality/security and markdown files for typos/grammar
- **Dependencies**: Requires internet access to GitHub and Anthropic APIs
- **Rate Limits**: Subject to GitHub and Anthropic API rate limits
These limitations help ensure fast, reliable reviews while managing API costs and complexity.

5. Generate token and copy the value
### ANTHROPIC_API_KEY
1. Go to https://console.anthropic.com/
2. Sign up/login
3. Go to API Keys section

You'll need to set up some environment variables to make it run.
- `ANTHROPIC_API_KEY` for LLM calls
- You'll need to follow [these instructions](https://docs.val.town/integrations/telegram/) to make a telegram bot, and set `TELEGRAM_TOKEN`. You'll also need to get a `TELEGRAM_CHAT_ID` in order to have the bot remember chat contents.
- For the Google Calendar integration you'll need `GOOGLE_CALENDAR_ACCOUNT_ID` and `GOOGLE_CALENDAR_CALENDAR_ID`. See [these instuctions](https://www.val.town/v/stevekrouse/pipedream) for details.
