## FAQ

### How does the agent know what to fix?

The agent uses tools to get comment context, including the file and line number, the viewport, screenshots, and surrounding markup.

### Can I use Maple without a GitHub repository?

Yes, if no GitHub credentials are provided, the server reads and writes comments to a local `.maple/` directory in the working directory.

### What happens if the agent tries to finish while comments are still open?

The maple-stop-hook can prevent the agent from finishing by blocking the session if there are still open or needing re-verification comments.
