Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears the full burden of behavioral disclosure. It adds that the result is 'ready-to-compose' and includes 'recommended MCP tools,' but it does not clarify whether resolution is a read-only lookup, how outputs are structured, what errors may occur, or any prerequisites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
