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 disclosing behavior. It only says 'Update Entity States' with no mention of side effects, permissions, reversibility, state transitions, or what distinguishes this mutation from other update tools. The agent cannot infer the behavioral contract.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
