Compare two sessions side-by-side using Agent Monitor data — per-model token usage (input/output/cache_read/cache_write + compaction baselines), pricing engine cost breakdowns, workflow intelligence (complexity scores, tool flow transitions, subagent effectiveness), session metadata (thinking_blocks, turn_count, turn_duration_ms, usage_extras), and full event timelines with all 10+ event types.
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
# Session Compare
Compare two Claude Code sessions side-by-side using Agent Monitor data.
## Input
The user provides: **$ARGUMENTS**
This may be:
- Two session IDs: "abc123 def456"
- "best vs worst" — compare highest and lowest productivity sessions
- "latest 2" — compare the two most recent sessions
- A session ID + "vs average" — compare one session against the baseline
## Procedure
1. **Identify sessions to compare**:
- If two IDs given: fetch both from `http://localhost:4820/api/sessions/{id}`
- If "best vs worst": fetch sessions, score by completion + cost efficiency, pick extremes
- If "latest 2": `GET /api/sessions?limit=2` (default sort: most recently updated first)
- If "vs average": fetch session + compute averages from last 50 sessions
2. **Gather detailed data** for each session:
- Session metadata: `GET /api/sessions/{id}`
- Events: `GET /api/events?session_id={id}`
- Agents: `GET /api/agents?session_id={id}`
- Cost: `GET /api/pricing/cost/{id}`
3. **Build comparison**:

How to install
mdr add hoangsonww/claude-code-agent-monitor/session-compare@sha256:1c38d46739830d50The 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.
