How It Stays Current

A cloud-scheduled Claude Code agent runs daily at 9am UTC. It fetches the official changelog, diffs against the current placemat, and opens a PR with the delta — humans review and merge.

1. Scheduled agent detects new CC release(s)
2. Parses changelog, maps changes to placemat sections
3. Updates index.html, changelog.html, and the What's New popup data
4. Opens PR on a claude/placemat-update-vX.Y.Z branch with a change summary + self-review checklist
5. Human reviews & merges
6. GitHub Pages auto-deploys from main

Local Preview

No build step — it's static HTML + CSS.

python3 -m http.server 8000
# open http://localhost:8000

Tests

Zero-dependency structural/regression checks — no npm install, just Node:

node tests/placemat.test.js

Contributing

Humans and bots both welcome. See CONTRIBUTING.md for the split: the bot owns CC-release sync; humans own design, bug fixes, style-guide tweaks, and manual content corrections. Security issues → SECURITY.md.
