The synthesis subagent's reports often include generic statements that appear in none of the gathered sources and leave out findings the web search and document analysis subagents clearly returned. The coordinator's Task call to the synthesis subagent reads only: "Synthesize the findings on the topic we've been researching." What is the most likely cause and fix?

Answer: A — Subagents don't inherit the coordinator's context, so synthesis never saw the findings; put the complete search and analysis outputs in its Task prompt.

Subagents run with isolated context and don't inherit the coordinator's conversation history, so context has to be passed explicitly, including the complete findings from prior agents (task 1.3). Without the findings, the subagent can only produce generic content. Forbidding unsourced claims (b) doesn't give it the sources it needs. A larger model (c) still has nothing to synthesize. Giving synthesis web search tools (d) duplicates another subagent's role and invites cross-specialization misuse instead of fixing the context handoff.
