Scan recent Claude Code activity for errors and failure signals across all sessions using Agent Monitor data — APIError events and PreToolUse→PostToolUse gaps (tools that started but never completed) — then group failures by tool and model and rank them by frequency. Use when checking for errors or asking "what's failing right now".
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
# Error Scan Sweep recent events across sessions for error and failure signals, then rank them by how often they occur and which tool or model produced them. ## Input The user provides: **$ARGUMENTS** This may be: - empty or "all" — scan every failure signal (default) - "api" — APIError events only - "tools" — tool-failure gaps only - a number N — limit the scan to the most recent N sessions - a session ID — scan a single session ## Data Sources | Endpoint | Returns | |----------|---------| | `GET /api/analytics` | `event_types` (counts per type incl. PreToolUse, PostToolUse, APIError), `tool_usage` (top 20), `daily_events` (365d) — fleet-wide failure baseline | | `GET /api/events?session_id=X` | Per-session event stream: `event_type`, `tool_name`, `summary`, `data`, `timestamp` — locate `APIError` and unmatched `PreToolUse` | | `GET /api/sessions?limit=N` | Sessions with `id`, `status`, `model`, `started_at` — pick the recent window and attribute failures to a model | ## Report Sections ### 1. Scope Resolve `$ARGUMENTS` to a session set: pull `GET /api/sessions?limit=N` (default 50, ordered by `started_at`). Report how many sessions and what time span are covered. …

How to install
mdr add hoangsonww/claude-code-agent-monitor/error-scan@sha256:4242e051fadff77cThe 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.
