# /receipts — personal Claude Code impact report Generates a markdown report of one developer's own Claude Code activity, built entirely from local data: - **Source data**: this machine's session transcripts at `~/.claude/projects/**/*.jsonl` (every session, every project, already on disk — nothing to set up). - **Cost**: the mining step is a local Node script — file I/O + regex, zero API calls. The only model call is one final write-up over a small (~10-20KB) JSON summary, regardless of how much history was scanned. - **Cross-reference**: local `git log` per repo (no network) to sanity-check commit activity against CC session activity. ## Step 1 — figure out the period Parse `$ARGUMENTS`: - "week" → 7, "month" → 30 (default if nothing given), "quarter" → 90, "year" → 365 - a bare number → that many days - a project name/substring (e.g. "for anthropic") → pass through as `--repo <substr>`. It matches against the resolved project name, case-insensitively, and scopes the entire report — totals included — to matching projects. ## Step 2 — run the miner The script `mine-transcripts.mjs` ships alongside this SKILL.md, under `scripts/`. Use its absolute path: ```bash node <skill-dir>/scripts/mine-transcripts.mjs --days <N> [--repo <substr>] --html /tmp/cc-receipt.html ``` Use that fixed temp path — the real `since`/`until` are computed by the script and only known once it has run, so don't try to put them in this filename. Steps 4 and 5 name the final files, by ...
