Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral burden; it does disclose the data source (platform DB) and that non-active endpoints are returned, which is real context beyond the schema. It omits ordering, pagination, and whether results are scoped to the agent or global, which matter for a list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
