You are an analyst reviewing a Claude response that addresses two of three required questions...

Under the objective Identify, diagnose, and resolve issues with underperforming prompts and/or poor outputs, diagnosing incomplete outputs requires mapping the specific failure mode directly to the corresponding prompt component.

When a model reliably answers some inquiries but completely omits another, the root cause is typically prompt ambiguity or buried instructions within dense prose. Strengthening the core task statement by explicitly enumerating the required deliverables (e.g., using numbered lists or tagged XML blocks like < question_1 > , < question_2 > , < question_3 > ) and mandating a complete response for each item (Option D) provides clear structural constraints that prevent omissions. Adding generic background context (Option A), changing persona framing (Option C), or relaxing output formatting constraints (Option B) fails to address the underlying instruction-following issue.
