description	Stop your AI from making the same mistake twice. Pre-Action Gates that block repeat hallucinations, retry loops, and known-bad tool calls before they reach the model — zero tokens spent on mistakes you've already corrected. Works with Claude Code, Cursor, Codex, Gemini CLI, Amp, OpenCode, and any MCP-compatible agent.

ThumbGate — Pre-Action Gates for AI Agents

Stop your AI from making the same mistake twice.

Repeated AI mistakes cost real money in tokens. Thumbs-down once — ThumbGate blocks that exact pattern on every future call, across every agent you use.

Quick Start

npx thumbgate init

Bootstraps .thumbgate/ and wires PreToolUse hooks into your agent. Works out-of-the-box with Claude Code, Cursor, Codex, Gemini CLI, Amp, OpenCode, and any MCP-compatible agent.

Core Commands

thumbgate capture "Never run --force push to main"   # create a rule
thumbgate gates list                                  # see active gates
thumbgate feedback down "agent ignored file paths"    # capture a thumbs-down
thumbgate lessons search "DROP TABLE"                 # recall prior lessons
thumbgate dashboard                                    # open the local dashboard

What ThumbGate Does

1. Capture — every thumbs-down on a bad agent action becomes a structured lesson.
2. Distill — lessons merge into prevention rules via history-aware synthesis.
3. Enforce — PreToolUse hooks physically block matching tool calls before the model is invoked. Zero tokens spent on the repeat.
4. Measure — live "tokens saved" counter in the dashboard puts a dollar number on every block.

When to Use This Skill

• The agent keeps hallucinating the same wrong import, wrong file path, or wrong command.
• You want destructive operations (DROP TABLE, git push --force, etc.) blocked at the tool-call layer, not the prompt layer.
• You need an audit trail of what the agent tried to do and was prevented from doing for compliance / review.
• You want DPO-ready preference pairs exported from your real feedback for fine-tuning.

Pricing

• Free CLI — 3 captures/day, 1 rule, 1 agent. MIT open source.
• Pro ($19/mo or $149/yr) — unlimited captures + rules, personal local dashboard, DPO export.
• Team ($49/seat/mo) — shared hosted lesson DB, org dashboard, workflow governance.
