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 conveys that the tool is read-only and returns the raw list scoped to the current session, but it does not disclose the output format, ordering, or whether retrieving the log has any side effects. This is adequate for a simple getter but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
