Self-test the Citadel hook pipeline from within a live session. Exercises real tool calls (Write, Edit, Bash, Read) and checks that hooks fired, telemetry accumulated, and no errors occurred. Reports HOOK HEALTH: PASS or HOOK HEALTH: FAIL with a per-hook breakdown.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /verify — Hook Pipeline Self-Test Use this when: - Hooks were recently updated and you want a live sanity check - Something feels wrong (tools seem too slow, quality-gate not firing) - After installing Citadel in a new project ## Protocol ### Step 1: Baseline Read the current telemetry state: ``` .planning/telemetry/hook-timing.jsonl → count lines (baseline_timing) .planning/telemetry/audit.jsonl → count lines (baseline_audit) .planning/telemetry/hook-errors.log → size in bytes (baseline_errors) ``` If telemetry directory doesn't exist, note it (init-project may not have run). ### Step 2: Exercise hooks Run these tool calls in sequence. Each exercises a different hook: 1. **Write** a temp file at `.planning/verify-temp.ts`: ```typescript // citadel verify probe export const verifyProbe = true; ``` → Exercises: PreToolUse (protect-files, governance), PostToolUse (post-edit) 2. **Edit** the same file — change `true` to `false`: → Exercises: PreToolUse (protect-files, governance), PostToolUse (post-edit) 3. **Bash** a harmless read command: `echo "verify-probe"` → Exercises: PreToolUse (governance) 4. **Read** the temp file back …

How to install
mdr add sethgammon/citadel/verify@sha256:90e2fd47bbb9553fThe line at the top of this page pins the label git:20260919.f58febd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
