Diagnose Claude Code hook installation, delivery, and ingestion issues. Checks hook configuration, connectivity, event flow, and identifies common problems. Use when events are not appearing in the dashboard.
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 Diagnostics Diagnose hook integration issues between Claude Code and the Agent Monitor. ## Input The user provides: **$ARGUMENTS** This may be: - "full" or empty (default: run all diagnostics) - "install" to check hook installation only - "connectivity" to check dashboard connectivity only - "events" to check event delivery only ## Procedure Run diagnostic checks in this order: ### 1. Hook Installation Check Verify hooks are installed in Claude Code settings: ```bash # Check if hooks exist in Claude Code settings cat ~/.claude/settings.json | jq '.hooks // empty' ``` Verify: - All 7 expected hook types are registered: `PreToolUse`, `PostToolUse`, `Stop`, `SubagentStop`, `Notification`, `SessionStart`, `SessionEnd` - Hook commands point to the correct handler script path - Handler script exists and is readable at the configured path ### 2.

How to install
mdr add hoangsonww/claude-code-agent-monitor/hook-diagnostics@sha256:7353b3f9c37570ecThe 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.
