What it does
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.
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
-
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
- If two IDs given: fetch both from
-
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}
- Session metadata:
