MCP App StoreMCP App StoreThumbGate provides a safety and reliability layer for AI coding agents. It captures structured feedback (thumbs-up/down) on agent actions and automatically promotes recurring failures into 'prevention rules.' These rules are injected into the agent's context to block known-bad tool calls before they execute.
Trigger this skill when you need to add safety guardrails to an AI workflow, prevent an agent from repeating a specific error, or export production feedback for DPO training.
capture_feedback, search_lessons, get_prevention_rules, session_primer, and export_dpo.Any MCP-compatible agent, including Cursor, Codex, Gemini CLI, Amp, and OpenCode.
