Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is communicated. The description adds only the fields retrieved, saying nothing about permission requirements, behavior for invalid/missing inode IDs, or whether invisible files are returned. With annotations carrying safety, this is adequate but thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
