• Weekly Reports (current week total/comparison with previous week)
• Monthly Reports (current month total/month-over-month growth)

bash {baseDir}/scripts/cost_report.sh --week

Cost Calculation Method

This script directly extracts cost data from OpenClaw session log files (~/.openclaw/agents/*/sessions/*.jsonl):

1. Uses jq to parse JSON data, locating the message.usage.cost.total field
2. Calculates totals grouped by date and model
3. Ensures each API call's cost is counted only once
