Checks

When a type or native check fails, read the diagnostic and fix it in chat or Code; the revision stays so you can repair it.

Updated Oct 11, 2026

The Status tab: open items, the app's three journeys marked Built, and the last checks, beside the preview
Status shows open items, the journeys and what the last checks found.

When a check fails

  1. Read the diagnostic: it names the file and the problem.
  2. Ask the assistant to continue from the error, or fix the file in Code.
  3. Send the follow-up. The next revision replaces the failing one.

Native build failures

The Build panel keeps the reason with the build and says who fixes it. Fix with AI starts a chat turn for a code problem, Retry build runs it again, and Show log reads the log, without secrets.

Good to know

  • Diagnostics stay with the project, not only in one chat message.
  • A failed check or a stopped turn never reverts the source. See Revisions and undo.
  • A failed native build is not charged.
