Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description discloses an important side effect: from_disk=True deletes files from disk. It also notes this applies only to downloads, which is a useful scope restriction. Missing details include whether removal is permanent, what happens to associated metadata, or required permissions, but the key destructive behavior is surfaced.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
