| description | 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. |
ThumbGate Doctor
Audit whether ThumbGate is actually wired into this agent — PreToolUse / SessionStart hooks
installed, MCP server reachable, lesson store present, statusline, overall agent-readiness — then
tell the user exactly what to fix.
This skill wraps existing ThumbGate capability and adds no new logic — it runs the existing
doctor + integrity checks.
Workflow
- Run the wiring/health audit:
npx thumbgate doctor
(Add --json for a machine-readable report.) It exits non-zero when the project is not ready.
- Verify the runtime path with the
check_operational_integrity MCP tool — this confirms the
server-side enforcement path is live, not just the local config.
- Summarize: ✅ what's wired (hooks, MCP, store, statusline) and ❌ what's missing, each with
its exact fix command (usually
npx thumbgate init).
- Lead with the fix. If everything is green, say so plainly with the readiness status; if not,
lead with the single highest-impact fix.
The full readiness checklist (each check, what a failure means, and its fix) is in
references/wiring-checklist.md.
Example
Input: "why aren't my gates firing? is ThumbGate even wired up?"
Action: run npx thumbgate doctor, then check_operational_integrity, then:
❌ PreToolUse hook not installed — run npx thumbgate init. ✅ MCP server reachable.
✅ Lesson store present. Fix the hook and your promoted rules will start blocking.
Troubleshooting
npx thumbgate doctor exits non-zero: that's the point — read which checks failed and apply
the printed fix (usually npx thumbgate init).- Doctor green but gates still don't fire: the rule may not be active — check the thumbgate-rules
skill — or no gated action has been attempted yet — check the thumbgate-blocked skill.
check_operational_integrity unreachable while doctor is green: local config is fine but the
MCP server isn't running — restart it (npx thumbgate serve).
