Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool focuses without triggering, which is useful behavioral context. However, it doesn't disclose other important traits: whether this requires specific permissions, what 'focus' means operationally (e.g., makes it active for editing vs. just selects it), or what happens if the presentation is already focused. For a mutation-like 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.
