The verifier subagent stopped while analyzing your previous turn. This can happen if:

- The verifier process crashed or was killed.
- The connection between the builder and verifier was lost.
- The verifier hit an internal error.

**No feedback was produced for the last turn.** You may want to:

1. Check the verifier process logs (visible in the builder's console output).
2. Re-enable verification with `/verify off` then `/verify on` if the issue persists.
3. Continue working — the builder session is unaffected.
