Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'List' implies a safe read and the 'system and session' scoping is genuinely useful behavioral context, but nothing is said about permissions, result ordering, or any side effects for session macros.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
