Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnlyHint true, destructiveHint false), and the description adds genuinely new behavior: no token required, and that returned snippets are partial and must be followed with filesfm_get_doc. The main weakness is the ambiguous instruction "Search tasks/create_document for task integrations," which does not make clear whether that is a doc path or a separate search term.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
