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.
- npm:
thumbgate - Dashboard: https://thumbgate-production.up.railway.app/dashboard
- Repo: https://github.com/IgorGanapolsky/ThumbGate (MIT)
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
- Capture — every thumbs-down on a bad agent action becomes a structured lesson.
- Distill — lessons merge into prevention rules via history-aware synthesis.
- Enforce —
PreToolUsehooks physically block matching tool calls before the model is invoked. Zero tokens spent on the repeat. - 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.

VerifiedTrustedCommunity
List the active ThumbGate prevention rules, reliability rules, and the promoted lessons behind them, so the user can see which guardrails are currently protecting this project and WHY each one exists. Reads the live rule and lesson stores via the prevention_rules, get_reliability_rules, and search_lessons MCP tools (CLI fallback `npx thumbgate rules`). Use when the user says "what is ThumbGate protecting me from", "show my rules", "show my gates", "what has the agent learned", "list active guardrails", or "what's blocked here". Do NOT use to CREATE a new rule (use the thumbgate-guard skill), to see runtime enforcement counts of what actually fired (use the thumbgate-blocked skill), or to diagnose whether ThumbGate is wired up at all (use the thumbgate-doctor skill).

tools
VerifiedTrustedCommunity
Inspect this repo's branch and release governance (protected branches, release rules, protected-file globs) and, only when the user explicitly approves, grant a scoped, time-limited exception so a protected-file edit or publish can proceed under audit. Reads posture via the get_branch_governance MCP tool and records a narrow, expiring approval via the approve_protected_action MCP tool. Use when the user says "is main protected", "show branch governance", "what am I blocked from editing", "approve this protected change", or "let me edit a protected file just this once". Do NOT use to disable protection wholesale, to grant broad or standing exceptions, or to diagnose hook wiring (use the thumbgate-doctor skill) — this skill is for narrow, temporary, audited approvals only.

VerifiedTrustedCommunity
Turn the agent's most recent mistake into an enforced ThumbGate prevention rule (a PreToolUse block gate) so the same bad tool call is intercepted before it runs again, in this and every future session across Claude Code, Cursor, Codex, Gemini, Amp, and Cline. Captures the failure with the capture_feedback MCP tool, then force-promotes it via `npx thumbgate force-gate` so it is enforced, not just logged. Use when the user says "guard against this", "block this from happening again", "never do that again", "make that a rule", "stop the agent from repeating that", or right after a bad action or thumbs-down that should become a hard rule. Do NOT use to merely log a thumbs-up/down without enforcement (use the thumbgate-feedback skill), to recall prior context before starting work (use the Agent Memory skill), or to list rules that already exist (use the thumbgate-rules skill).

tools
VerifiedTrustedCommunity
Health-check whether ThumbGate is actually wired into this agent — PreToolUse/SessionStart hooks installed, MCP server reachable, lesson store present, statusline, and overall agent-readiness — then report exactly what to fix. Runs the existing `npx thumbgate doctor` audit and the check_operational_integrity MCP tool. Use when the user says "is ThumbGate wired up", "thumbgate doctor", "check my guardrails are installed", "why aren't my gates firing", "is the MCP server connected", or "agent readiness". Do NOT use to view rules (use the thumbgate-rules skill), to view what was blocked (use the thumbgate-blocked skill), or to capture a new rule (use the thumbgate-guard skill) — this skill only diagnoses setup and wiring.
