Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state whether this is a read-only aggregation tool or one that mutates state (e.g., writes files, creates artifacts). 'Orchestrate complete architecture workflow' strongly implies it may call other tools or perform multiple side effects, but the description doesn't disclose what gets changed, what's created, or what side effects occur.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
