# Drop this file into your repo at .github/workflows/ccmeter-pr-cost.yml
# It posts the Claude Code spend for a PR (since the branch was created)
# back as a sticky comment. Useful for tracking how much "vibe-coding" each PR
# actually cost in Claude Code time.
#
# Prereq: each contributor needs to run `ccmeter export --format json --out
# .ccmeter-export.json` locally and commit it on the branch (or your CI bot
# can mount the contributor's ~/.claude/projects). Treat the export as a
# build artifact, not a source-of-truth — the file is JSON, no secrets.
