Cost Tracking Use this skill to analyze Claude Code cost and usage history from the metrics log that ECC's stop:cost-tracker hook writes. Where the data lives The tracker appends one JSON object per session-stop to ~/.claude/metrics/costs.jsonl . Each row is a cumulative snapshot for that session , so to total spend you take the latest row per session_id and sum across sessions — summing every row multiply-counts.
