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 only offers the cryptic '(Compatibility tool)' hint without explaining side effects, idempotency, whether it modifies the scene file immediately, or what the 'Compatibility' designation implies for behavior (legacy support?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
