Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'update' implies a mutation but fails to describe what happens during the update (e.g., whether it overwrites existing data, requires permissions, or has side effects). It does not mention error conditions, rate limits, or what the tool returns, leaving the agent with minimal behavioral insight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
