Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It conveys only that the tool toggles a promotion state, but it omits side effects (e.g., price/visibility changes when disabling a promotion), preconditions (the action must be in a togglable state), idempotency behavior, and any response or error semantics. For a mutating tool this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
