How to use it safely
- ✓ Only give it the folders it needs; files it reads can end up in the AI’s context.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ Use a key with the smallest permissions available, and never paste a production key into a shared config.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
