Prompt for AI agents (unresolved issues)

```text Check if these issues are valid — if so, understand the root cause of each and fix them. If appropriate, use sub-agents to investigate and fix each issue separately. P2: The happy-path success criteria dropped verification of the required post count, so this test can pass even if the workflow misses part of the requested Slack summary. P1: Structured output schema does not match the verifier prompt contract (array + nullable fields), so valid model responses can be rejected and still fall back to missing verification results. ```
