Audit hook delivery health from Agent Monitor data — balance PreToolUse vs PostToolUse (a gap means tools that started but never reported back), detect missing Stop/SubagentStop terminators (sessions/subagents that never closed), and check for stale ingestion (no recent events). Use when hooks look unreliable or events seem to be dropping.
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
# Hook Failure Audit Assess whether the hook pipeline is delivering events reliably, using the event counts and stream the dashboard already has. This is about *delivery* health (missing/dropped events), not about why a model errored. ## Input The user provides: **$ARGUMENTS** This may be: - empty or "all" — run every check (default) - "balance" — PreToolUse/PostToolUse balance only - "terminators" — missing Stop/SubagentStop only - "freshness" — stale-ingestion check only ## Data Sources | Endpoint | Returns | |----------|---------| | `GET /api/analytics` | `event_types` (counts per type: PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd), `daily_events` (365d), `total_subagents`, `sessions_by_status` — fleet-wide delivery balance | | `GET /api/stats` | `total_sessions`, `total_agents`, `total_events`, `events_today` — expected terminator counts and recency | | `GET /api/events?session_id=X` | Per-session stream — confirm which sessions are missing a `PostToolUse`, `Stop`, or `SubagentStop` | ## Report Sections ### 1.

How to install
mdr add hoangsonww/claude-code-agent-monitor/hook-failure-audit@sha256:02967e1035f4b8ffThe line at the top of this page pins the label git:20260804.9eab0d7, 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.
