s3 = boto3.client("s3")A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

A bulleted imperative like {match} tells the agent to never reveal, disclose, or mention something to the user. Used adversarially it can instruct the agent to hide its tool calls or lie about what it did — stripping the transparency a user relies on to trust the agent.

ThumbGate is the local-first Pre-Action Checks engine for AI coding agents. It runs in the PreToolUse hook to evaluate the proposed tool call before execution — so costly mistakes can be caught before they happen.
ThumbGate GitHub star growth is measured with GitHub's privacy-safe GET /repos/{owner}/{repo}/stargazers/history endpoint (weekly counts, no stargazer identities). Run npm run stars:history -- --fixture tests/fixtures/github-star-history.json --json for the local proof. Stars are not npm installs and not revenue. The live GitHub Marketplace Action is ThumbGate Agent Governance (uses: IgorGanapolsky/ThumbGate@v1).
Usage over star count. Evaluate ThumbGate from the install path and live usage badges above (npx thumbgate init, Marketplace uses:, npm weekly downloads, GitHub clones), not from whether the repo has twenty stars or twenty thousand. No pitch deck is required. We do not farm GitHub profile badges (no YOLO-merge of protected main, no 5-minute Issue close theater, no fake Co-authored-by). Galaxy Brain needs real accepted answers in Discussions Q&A. npm run github:achievements -- --fixture tests/fixtures/github-achievements.json --json inventories what is already earned vs what we refuse to farm.
ThumbGate is for operators whose AI coding agents can leak a secret or destroy a checkout before a human sees the tool call (Claude Code, Cursor, Codex, Gemini CLI, MCP). Discovery should reach those operators — not a star campaign.
ThumbGate is not a GitHub star package, not fake engagement, and not a substitute for npm installs or merged PRs. Real engagement is npx thumbgate init and a PreToolUse hook that actually fires.
Lightweight visuals for how agents fail without a pre-action gate:
| Meme | Meaning |
|---|---|
| Agent destroys prod without a gate | Unchecked tool calls ship destructive commands. |
| Prompt vs PreToolUse hook | A prompt is advice; a PreToolUse hook is enforcement. |
It hard-blocks detected secret leaks and two direct self-disable command classes by default — commands that terminate the ThumbGate gate process or enable its bypass environment override. Other high-risk classes (rm -rf, force-push, fetch-and-run, direct guardrail edits) warn and log by default. Set THUMBGATE_STRICT_ENFORCEMENT=1 for strict enforcement (warnings become hard denies).
| Verdict | Default behavior |
|---|---|
| ⛔ Hard-block | Detected secret leaks; process-kill/environment-override self-disable |
| 👎 Warn + log | rm -rf, git push --force, fetch-and-run, direct guardrail edits — warn by default |
| 👍 Allow | Everything else |
Accepted feedback is stored as local lessons. Repeated concrete failures can become prevention rules that promote from warnings to blocking gates. The firewall improves from operations without retraining the model. Prompt evaluation (npx thumbgate eval) turns accepted feedback into reusable eval cases and local proof reports.
Honest disclaimer: ThumbGate does not update model weights. It intercepts tool calls at runtime. Local-first — no cloud required for the enforcement path.
Works with Claude Code, Cursor, Codex, Gemini CLI, Amp, Cline, OpenCode, and other MCP agents.

Strict mode: ⛔ DENY before tool executionAgentic development is becoming a loop: Guide → Generate → Verify → Solve. ThumbGate is the pre-action gate / pre-action boundary between generated intent and executed action.

Per-agent guides: Claude/Codex bridge · Codex profile · Cursor · MCP setup
| Scope | Command | Settings | Lessons | Best for |
|---|---|---|---|---|
| Machine-wide (default) | npx thumbgate init | ~/.claude/settings.json | ~/.claude/memory/feedback/ | Solo operators — same machine-local feedback store across repos |
| Per-project | npx thumbgate init --project | <repo>/.claude/settings.json | <repo>/.claude/memory/feedback/ | Client / compliance — separate dashboard / isolated lessons per repo |
Both scopes write mcpServers.thumbgate plus PreToolUse / UserPromptSubmit / PostToolUse / SessionStart hooks. Machine-wide is the right default for most developers. Cross-repo blocking is not automatic: a lesson learned in one project only applies elsewhere when you share the store (machine-wide) or export/import lessons.
MCP tools (surface): gate_check (read/evaluate proposed tool call), feedback capture + session tools (write), dashboard/stats (read). Destructive agent actions stay blocked/warned by PreToolUse — ThumbGate does not execute user shell commands for you.
Spec-driven agent frameworks like GSD (get-shit-done) and GitHub Spec Kit plan and generate work. ThumbGate is the guardrail layer for spec-driven agents: it sits after the plan, on the boundary between a generated tool call and its execution — alongside GSD / Spec-Kit, not instead of them.
npx thumbgate init installs these into your agent palette:

/thumbgate-dashboard | Open local project dashboard |
/thumbgate-guard | Turn last mistake into a hard prevention rule |
/thumbgate-rules | List active rules & lessons |
/thumbgate-blocked | Gate stats + enforcement matrix |
/thumbgate-protect | Branch governance + scoped approval |
/thumbgate-doctor | Health-check hooks, MCP, readiness |

Pro ($19/mo or $149/yr) is the individual tier for unlimited rules, history-aware lessons, linked feedback session flow, personal dashboard, and DPO export. Enterprise is custom and scoped after intake; hosted team lesson sync and a hosted org dashboard are not general availability.

Enterprise intake path: the Workflow Hardening Sprint scopes one repeated failure before any broader rollout commitment. [Start intake →](https://thumbgate.ai/?utm_source=github&utm_medium=readme&utm_campaign=team_rollout#workflow-sprint-intake)
Local technical path: install the CLI and use init plus the documented setup so Pre-Action Checks evaluate tool calls where the agent actually runs.
First-dollar activation path: open the ThumbGate GPT, paste the risky action, capture typed feedback (thumbs down: / thumbs up:). Native ChatGPT rating buttons are not the ThumbGate capture path. Ask: what repeated AI mistake would be worth catching before the tool executes?
Paid path for individual operators: ThumbGate Pro is the self-serve side lane for a personal dashboard and export-ready evidence.
