[Scenario: Multi-agent Research System] After running the system on “AI impact on creative industries,” you observe that every subagent completes successfully: the web-search agent finds relevant articles, the document analysis agent summarizes them correctly, and the synthesis agent produces coherent text. However, final reports cover only visual art and completely miss music, literature, and film. In the coordinator logs, you see it decomposed the topic into three subtasks: “AI in digital art,” “AI in graphic design,” and “AI in photography.” What is the most likely root cause?

• A.The synthesis agent lacks instructions to detect coverage gaps.
• B.The document analysis agent filters out non-visual sources due to overly strict relevance criteria.
• C.The coordinator’s task decomposition is too narrow, assigning subagents work that does not cover all relevant areas.
• D.The web-search agent’s queries are insufficient and should be broadened to cover more sectors.

Show answer & explanations

Correct answer: C

A: The synthesis agent never received music, literature, or film because those subtasks were never created. A coverage check cannot invent the missing research.

B: The document agent summarised what it was given. The coordinator log shows only visual-art subtasks.

C: The coordinator decomposed a broad topic only into visual-art subtasks, missing music, literature, and film entirely. Since subagents executed their assignments correctly, the narrow decomposition is the obvious root cause.

D: Wider search queries do not fix a decomposition that never asked about those sectors.
