Why it matters

AI agents repeat the same mistakes across sessions because they lack feedback loops. ThumbGate captures thumbs-up/down signals and turns them into searchable lessons with enforced gates — a lightweight quality ratchet for any agent.

Best for

Teams running multiple AI coding agents (Claude, Cursor, Codex, Gemini) who need a shared mistake-prevention layer across tools.
