ThumbGate

Active·★ 21·MIT·Updated 2026-05-29
★ Trending★ Security & Safety★ Dev Tooling

Pre-action gates for AI coding agents. Skill disclosure cuts tokens. Hallucination and PII checks harden outputs. 👍 Thumbs up reinforces good behavior. 👎 Thumbs down blocks repeated mistakes. Free is local. History-aware lessons distill vague feedback. Team adds shared lessons and org visibility, plus generated review views.

ThumbGate is a safety net for vibe coding. It captures thumbs-down feedback, auto-generates prevention rules, and pre-action gates physically block the agent before it repeats a known mistake. It works with Claude Code, Cursor, Codex, Gemini, Amp, OpenCode, and any MCP-compatible agent, providing a reliability layer without an extra orchestrator.
