hook-failure-audit
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.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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.

What does the hook-failure-audit skill do?
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.
How do I install it?
Run `npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill hook-failure-audit --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From hoangsonww/Claude-Code-Agent-Monitor, a repository with 869 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
