What it does
A pre-action firewall for AI coding agents. It turns thumbs-up and thumbs-down feedback into rules, and PreToolUse hooks enforce those rules before a tool call runs. The goal is to stop an agent from repeating a mistake it has already made.
Use cases
- 01Blocking a command that deleted files before
- 02Stopping an agent from pushing a leaked key
- 03Turning feedback on a bad change into a rule
