Identify anomalous sessions using Agent Monitor data — cost outliers from the pricing engine, token anomalies (cache miss spikes, compaction baseline surges), unusual event type ratios (PreToolUse/PostToolUse gaps, APIError clusters), behavioral deviations from workflow intelligence (complexity score outliers, error propagation anomalies), and sessions with abnormal metadata (extreme turn_count, high thinking_blocks, zero turn_duration).
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
# Anomaly Alert Detect anomalous sessions in Claude Code Agent Monitor data. ## Input The user provides: **$ARGUMENTS** This may be: - "all" or empty (default: check all anomaly types) - "cost" for cost anomalies only - "duration" for duration anomalies only - "errors" for error rate anomalies only - A sensitivity level: "strict" (1σ), "normal" (2σ), "relaxed" (3σ) ## Procedure 1. **Fetch baseline data** from `http://localhost:4820`: - `GET /api/sessions?limit=500` — historical sessions for baseline - `GET /api/analytics` — aggregated metrics - `GET /api/pricing/cost` — cost data per session 2. **Compute baselines** for each metric: - Mean, median, standard deviation - P25, P75, P90, P95, P99 percentiles - Interquartile range (IQR) for robust outlier detection 3. **Detect anomalies** using statistical thresholds: ### Cost Anomalies - Sessions costing >2σ above mean - Single sessions exceeding daily average - Sudden cost spikes (session-over-session increase >200%) ### Duration Anomalies - Sessions lasting >2σ above mean duration - Extremely short sessions (<1 minute) that still incur cost …

How to install
mdr add hoangsonww/claude-code-agent-monitor/anomaly-alert@sha256:7ae5f37440aa464bThe 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.
