What it can access
- An AI agent decides its own next steps and calls whatever tools you give it, so its risk depends on the access you grant.
Before you install
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by Windy3f3f3f3f on GitHub, 2,806 stars and 558 forks. Popularity is not proof of safety.
- Last code change: Jul 9, 2026.
- Open-source license: MIT.
