Executive Snapshot

Signal	Value	Why it matters
Session	6e551372-2428-4ed6-9346-ec3b605952ff	Lets you link this export back to the source interaction stream.
Project	m-agent	Identifies where the report came from.
Model	claude-opus-4-6[1m]	Shows which model produced the session.
Duration	24h 20m 23s	Helps you relate context growth to session length.
Report span	2026-04-01 10:44:55 -> 2026-04-02 11:05:18	Gives the exact time range covered by the export.
Interactions	165	Shows how active the session was overall.
Produced by	cc-context-stats v1.15.0	Shows which tool generated the report.
Generated	2026-04-02 11:17:43	Records when the report was produced.
Final usage	350,904 (35.1%)	Shows how close the session ended to the context limit.
Final zone	Dead zone	Indicates whether the session stayed in a safe working range.
Cache activity	350,901 (100.0%)	Explains how much of the final context is cache-related.

Context Usage

Context usage: ███████░░░░░░░░░░░░░ 35.1%

Key Takeaways

• Final state: 350,904 used (35.1%) and currently in the Dead zone.
• Growth: context increased by 320,178 tokens over 24h 20m 23s (32.0% of the window).
• Largest jump: 30,726 tokens at interaction #1.
• Dominant zone: Dead zone for 82 of 165 interactions.
• Cache load: 350,901 tokens in cache activity (100.0% of the final used context).
• Cache pattern: more cache creation than cache reads, so the session leaned toward new cache material.

Visual Summary

Context Trend

Shows how much context was used at each sampled point so you can spot growth, resets, and sudden jumps.

Cache Activity Trend

Shows how cache creation and cache reads evolved over time so you can see when the session started reusing previous work versus building new cache.
