Option B identifies the missing executable capability. Defining specialized agents makes their configurations available, but the coordinator must still be permitted to call the tool that invokes them. Without that tool, Claude can describe an intended delegation in ordinary text but cannot create a subagent execution.

The current Claude Agent SDK documentation requires " Agent " in allowedTools to auto-approve subagent invocations. The tool was renamed from " Task " to " Agent " in Claude Code 2.1.63, so the terminology in the original candidate question required correction. Older integrations may still expose " Task " in initialization or permission records.

Option A is unlikely because properly written AgentDefinition.description values already tell Claude when each agent should be used. Option C misinterprets context isolation: the parent supplies the subagent’s assignment through the Agent tool’s prompt, and no additional automatic forwarding setting is required. Option D would normally produce truncation evidence or a max_tokens stop reason rather than silent absence of every invocation. The coordinator needs both agent definitions and permission to use the invocation tool.

Option C respects the customer’s explicit request for human assistance. The agent should not attempt to retain the interaction, gather additional account information, or require the customer to repeat the request. Because the escalation decision has already been made by the customer, further autonomous investigation would create unnecessary delay and disregard clear human direction.

Anthropic’s trustworthy-agent framework emphasizes maintaining meaningful human control over agent autonomy. Anthropic’s customer-support implementation guidance also recommends defining interaction branches and measuring escalation efficiency as part of the system’s success criteria.

Option A deliberately delays escalation despite an unambiguous request. Option B performs unnecessary tool calls and may expose or retrieve account information that is not required before transferring the conversation. Option D similarly introduces another conversational barrier. Since the current exchange is short and contains no tool-generated evidence, passing the available conversation history gives the human agent the immediate context—the customer’s frustration, repeated unsuccessful attempts, and explicit transfer request—without pretending that account investigation has occurred.

Option C preserves the semantic strengths of each information type instead of forcing heterogeneous evidence into one presentation structure. Financial values share comparable fields and therefore belong in a table. News developments require connected prose to preserve chronology and causality. Patent technology areas are naturally represented as grouped or prioritized lists.

Anthropic’s prompting best practices recommend giving explicit output-format instructions and matching the requested format to the intended communication goal. The synthesis prompt should therefore include rendering rules for each recognized content type while maintaining common provenance fields behind the presentation.

Option A damages numerical comparability and makes trends harder to scan. Option B can be useful as an internal exchange schema, but presenting the entire briefing as uniform JSON does not produce an effective executive document. Option D normalizes transport but does not correct the synthesis agent’s bullet-only rendering policy; a common representation can still be displayed badly. The correct design separates structured internal interchange from audience-facing presentation. The synthesis agent should preserve citations and metadata while selecting the most legible form for each class of evidence.
