Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full behavioral burden. It merely labels the content as a catalog of swimlanes and does not disclose return format, whether the catalog is static or dynamically generated, or whether any side effects occur. The read-only nature is only inferable from the 'get' prefix, not from the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
