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 mentions the effect ('stopping its frame-tick effect'), which adds some context about what the removal entails, but fails to cover critical aspects like whether this is reversible, requires specific permissions, or has side effects on related objects. For a mutation tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
