問題文
A research agent has two MCP tools whose descriptions are "Analyzes content and returns insights" and "Analyzes documents and returns insights." In production the agent routes web search results to the document tool and PDF files to the content tool roughly a third of the time. What is the root cause?
選択肢
- The two tool descriptions are nearly identical, and tool descriptions are the primary mechanism the model uses to select a tool.
- The agent has too many tools available, which degrades selection reliability.
- The model needs tool_choice set to "any" so it is forced to pick one of the two tools.
- The MCP server is returning results too slowly, so the agent retries with the other tool.
