Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered and nothing is contradicted. However, the description adds no behavioral context at all - it never explains what 'api composer data' is, whether auth is required, or what openWorldHint implies for this call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
