name: hook-inventory description: > Inventory hooks across the user, project, and project-local settings plus the ~/.claude/hooks scripts directory — read through the Agent Monitor Config Explorer API — and flag hooks that POST to the network or run arbitrary commands. Reads /api/cc-config/hooks and /api/cc-config/hook-scripts. Use when auditing hook safety.

Hook Inventory

Catalogue every Claude Code hook the user has configured and assess its safety — read through the Agent Monitor dashboard at http://localhost:4820.

Input

The user provides: $ARGUMENTS

This may be:

• empty — inventory all hooks across every scope (default).
• an event name (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, Notification, PreCompact) — restrict to that event.
• "scripts" — focus on the ~/.claude/hooks handler scripts dir.

Data Sources

| Endpoint | Returns | |----------|---------| | GET /api/cc-config/hooks | { items:[{ scope:"user"\|"project"\|"project-local", file, exists, hooks:{ <Event>:[{ matcher, type, command, timeout }] } }] } | | GET /api/cc-config/hook-scripts | { dir, items:[{ name, file, size, mtime }] } — the handler scripts under ~/.claude/hooks/ |

Report Sections

1. Configured hooks by scope

From /hooks, flatten each source into (scope, file, Event, matcher, type, command, timeout). Group by scope (user, project, project-local). Show the event, matcher, hook type, and the raw command. Note which file each came from so the user can edit the right one.

2. Hook scripts on disk

From /hook-scripts, list each file in ~/.claude/hooks/ with name, size (KB), and mtime. Cross-reference: flag scripts referenced by a hook command but missing from disk, and scripts on disk that no configured hook calls (orphaned).

3. Safety flags

For every type: "command" entry escalate:

• Network egress (P0) — the command contains curl, wget, http, https, nc, or pipes output off-box. Print the destination if visible.
• Arbitrary execution (P1) — pipes to sh/bash, evaluates downloaded content, or runs an unpinned interpreter on attacker-influenceable input.
• No timeout (P2) — a command hook with timeout: null; it can hang a session indefinitely.
• Broad matcher (P3) — matcher: "*" or empty on a destructive command.

Output

• Section 1 as a table (Scope | Event | Matcher | Type | Command | Timeout).
• Section 3 as a findings table (Hook | Risk | Severity | Detail) with a one-line verdict first (SAFE / REVIEW NEEDED / RISKY HOOKS).
• Print raw commands verbatim — do not paraphrase a command you are flagging.
• Cite only fields the API returned — never fabricate hooks or commands.
• Note: hooks live inside settings.json and are read-only via the Config Explorer; edit them in the file named by the source, then reinstall with the dashboard's hook setup if needed.
• If the dashboard is unreachable at http://localhost:4820, say so and tell the user to start it with npm start from the repo root.
