Agent governance that stops costly AI mistakes before they run: pre-action gates, shared lessons, and team safeguards for AI coding workflows.

ThumbGate

Your AI coding bill has a leak.

Stop paying $ for the same AI mistake.

Every retry loop, every hallucinated import, every "let me try a different approach" — those are billable tokens on every LLM vendor's bill. Thumbs-down once; ThumbGate blocks that exact mistake on every future call. Across Claude Code, Cursor, Codex, Cursor, Amp, OpenCode — any MCP-compatible agent, forever.

Under the hood: your thumbs-down becomes a Pre-Action Gate that physically blocks the pattern permanently on every future call — across every session, every model, every agent. It is self-improving agent governance: every correction promotes a fresh prevention rule, and your library of Pre-Action Gates grows stronger with every lesson. Works with Claude Code, Cursor, Codex, Cursor CLI, Amp, OpenCode, and any MCP-compatible agent. The monthly Anthropic / OpenAI bill stops paying for the same lesson over and over — local-first enforcement, zero tokens spent on repeats.

Prevent expensive AI mistakes. Make AI stop repeating mistakes. Turn a smart assistant into a reliable operator.

Mission: make AI coding affordable by making sure you never pay for the same mistake twice.

First-dollar activation path

If someone is not already bought into ThumbGate, do not lead with architecture. Lead with one repeated mistake.
