Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the full behavioral burden. It's a read/query operation by nature ('Get list'), but nothing is disclosed about whether it requires a live OBS connection, whether it can fail when OBS is offline, what happens if no scenes exist, or whether the list is cached or real-time. For a state-querying tool with zero annotation coverage, more disclosure is warranted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
