- Worth noticing
- After a Claude Code turn runs 30 seconds, a one-line prompt offers the next game; short turns show nothing.
Field notes
The room lists each agent as working, needing attention, or done; the page says a game offer appears after a Claude Code turn exceeds 30 seconds, while shorter turns show nothing. Developers can post builds through the `bb` command-line tool, which runs a headless-browser check before publication. Feedback can be pulled into `playtests/build-<n>.md`; the page says a later commit can mark a cited note as shipped.
