What it does

Once installed, the agent can read your local Claude Code session logs (stored under ~/.claude/projects) and summarise how many tokens you used over a chosen period, broken down by project, subagent type, skill, cache misses and expensive prompts. It then fills a bundled HTML template with that data and saves a self-contained, explorable report file in your current folder, plus a few plain-English findings and optimisation tips.

Great for

  • Developers who use Claude Code heavily and want to see where their tokens go
  • Teams trying to cut down on subagent or cache-related costs
  • Anyone who wants a weekly summary of their Claude Code usage

Skip it if

  • People who do not use Claude Code, since there are no transcripts to analyse
  • Users sharing their machine or reports publicly: the report contains prompt excerpts and project names from your private session history

Try asking

  • “Generate a session report for the last 7 days”
  • “Make a Claude Code usage report for the last 30 days and highlight expensive prompts”
  • “Show me which projects used the most tokens all time in an HTML report”
  • “Create a 24h session usage report with cache hit analysis”
