Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'Clear[s] all stored logs from memory', implying a destructive operation, but doesn't specify whether this is irreversible, requires permissions, affects system performance, or has side effects. More context is needed for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
