Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, and it does disclose the key trait: it executes destructive operations (deletes/commands) and requires explicit user approval. However, it doesn't state whether the executed ids are removed from the queue, what happens with invalid/already-processed ids, or whether the effect is reversible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
