Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It only states 'create or replace', which implies overwriting behavior, but fails to disclose any other behavioral traits such as idempotency, limits, or side effects. No details about what happens when a tax table already exists or error conditions are given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
