Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool performs a 'Set' operation, implying mutation, but doesn't disclose behavioral traits such as whether it requires specific OBS states (e.g., studio mode), if changes are immediate or reversible, or any error conditions (e.g., invalid transition name). This leaves significant gaps for safe agent use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
