Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states 'applies', which implies a mutation, but does not disclose what side effects occur, whether changes are reversible, what inputs are required for a successful application, or what the tool returns. This is severely lacking for a likely mutating operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
