What it measures

Reads your ~/.claude/projects/**/*.jsonl session files and groups them by day of week. Shows:

• Sessions and hours per day-of-week
• Average session length per day (reveals focus depth vs quick checks)
• Weekday vs weekend split
• Your coding pattern: Weekday grinder, Mostly weekdays, Weekend hacker, or Always on

Sessions over 8 hours are excluded (likely autonomous overnight runs).
