cc-debrief

Post-session debrief for Claude Code transcripts.

See where every token went — repeated reads, idle gaps, model overuse, hidden subagent cost — and get a personalised checklist of fixes for next session. 100% local. No LLM. No upload.

Pick your .claude folder, or a specific project folder under projects/

100% local No LLM calls No API key MIT licensed ~100 ms per session
Folder lives at %USERPROFILE%\.claude (Windows) or ~/.claude (macOS, Linux). Browsers can't auto-navigate to a specific path for security reasons; on Chrome/Edge, the picker remembers your last location so the second pick onwards is one click.
Privacy: nothing is uploaded. No LLM calls, no API key, no internet — your transcripts and the rendered report stay on this machine.

How does this compare to Claude Code's built-in /insights?

In April 2026 Anthropic shipped a built-in /insights command that also generates an HTML session report. The two tools are complementary, not redundant — different shape, different cost model, different use cases.

/insights qualitative

  • Haiku LLM reads your sessions
  • Sentiment, frustration patterns, themes
  • Sends sessions through the API
  • Costs subscription tokens
  • Last 30 days of sessions

cc-debrief quantitative

  • Pure deterministic, ~100 ms per session
  • Cache TTL, subagent split, repeated calls, idle gaps
  • 100% local — no network, no API
  • Zero token cost
  • One session OR cross-session combined
