Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description is transparent for a simple read/list operation. It explicitly says 'List' and includes the qualifier 'persisted local,' indicating the data source and storage nature. No annotations are provided, but the behavior is self-evident and unlikely to have side effects. It lacks details like filtering or response structure, but the output schema covers that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
