Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the behavioral disclosure burden. It provides meaningful selection behavior: a symbol resolves to LoomDesk's own pool if available, otherwise the deepest pool, and a pool id can be passed directly. It does not mention failure modes or return format, but for a read-style getter the key behavioral nuances are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
