JSON output

For CI pipelines, dashboards, or programmatic use:

npx cc-session-stats --json

Outputs structured JSON to stdout:

{
  "version": "1.0",
  "totalSessions": 3405,
  "totalHours": 102.12,
  "activeDays": 47,
  "totalDaysSpan": 50,
  "firstSeen": "2026-01-10",
  "lastSeen": "2026-02-28",
  "averages": { "perSession": 0.03, "perDay": 2.17 },
  "longestSession": { "hours": 3.89, "date": "2026-02-28", "project": "cc-loop" },
  "hoursByDayOfWeek": { "Sun": 20.27, "Mon": 17.2, "..." : "..." },

  "streak": 35,
  "healthWarnings": ["35 consecutive days of AI usage. Rest days exist for a reason."],
  "last7Days": { "hours": 24.72, "activeDays": 8 }
}

How it works

1. Scans ~/.claude/projects/ for session transcript files (.jsonl)
2. Reads first and last line of each file for timestamps
3. Calculates session durations and aggregates stats
4. Includes subagent sessions (Task tool spawns)

Zero dependencies. No data sent anywhere. Runs entirely local.

Health warnings

The tool flags concerning patterns:

Pattern	Warning
Sessions over 3 hours	Your spine has opinions
7+ consecutive days	Rest days exist for a reason
Average session > 2 hours	90-minute focus blocks are backed by research
6+ hours/day average	That's a full workday of sitting
