Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries full burden. It mentions 'reduces hallucination via graph context' but does not disclose important behavioral traits such as error handling, resource consumption, state changes (e.g., file creation), or authentication failure behavior. The PRO note implies a cost but no details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
