Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full behavioral burden, yet it discloses nothing about what the call returns, whether the optional query scopes or replaces the output, or how the prompt/playbook is delivered. Phrases like "Save hours every week" and "battle-tested" are promotional claims, not behavior. For a zero-annotation tool this leaves the agent blind.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
