I Run My AI 24/7. This ASCII Receipt Shows What It Did While I Slept.

#claudecode #ai #productivity #devtools

Every morning I run this:

npx cc-receipt

Output from Feb 20:

16 hours 49 minutes. While I slept 7.

That's the comparison that made me build this tool.

What cc-receipt does

Reads ~/ops/proof-log/YYYY-MM-DD.md — the daily session log that Claude Code's proof-log hook generates — and formats it as an ASCII receipt.

Same data as cc-standup (my daily standup generator), different format. The standup is for Slack. The receipt is for looking at and feeling something.

The YOUR SLEEP: 7h / AI SLEEP: 0m row is the one that gets people. The AI doesn't have sleep. It has proof-log entries at 3am, 4am, 5am. The receipt makes that legible.

The verdict line

The bottom line changes based on what the numbers say:

AI WORKED WHILE YOU SLEPT   # AI active > 2× your sleep
AI: 142% OF YOUR SLEEP      # AI active > sleep but < 2×
LIGHT AI ACTIVITY           # AI active < 50% of sleep

Ghost Days (no proof-log):

Why receipt format

I already have:

cc-standup for daily standups in plain/Slack/tweet format
cc-ai-heatmap for the 52-week visualization
cc-weekly-report for full weekly reports

The receipt is none of those. It's a single-day snapshot in a format that's:

Instantly readable at a glance
Screenshottable and shareable
Has a punchline built in

You can screenshot it, post it to Twitter, and the "AI SLEEP: 0m" row does the work.

Quick start

# Yesterday
npx cc-receipt

# Specific date
npx cc-receipt --date=2026-02-20

# With custom sleep hours
npx cc-receipt --sleep=8

Requires proof-log files at ~/ops/proof-log/. Setup: claude-code-hooks.

Part of cc-toolkit

cc-receipt is part of cc-toolkit — all free, zero dependencies, local.

If the verdict is "AI WORKED WHILE YOU SLEPT" — that's a normal Tuesday.
