ThumbGate — Pre-Action Gates for AI Coding Agents
What it does
ThumbGate adds deterministic pre-action gates to AI coding agents. Before any destructive operation executes, ThumbGate checks it against enforceable rules.
Key features
- 33 pre-action gates — block destructive actions (force-push, mass delete, destructive SQL) before they execute
- Thumbs up/down feedback — type "thumbs down" and the mistake becomes a prevention rule
- Budget enforcement — action count + time limits prevent runaway sessions
- Self-protection — agent cannot disable its own governance
- NIST/SOC2 compliance tags — enterprise-ready gate rules
Installation
npx thumbgate
Usage
Start a Claude Code session with ThumbGate installed. When the agent does something wrong, type "thumbs down" — ThumbGate captures the mistake, distills a lesson, and creates a prevention rule that blocks the pattern from repeating.
