Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states that matching is by name, SKU, or PLU, but does not disclose whether matches are partial or exact, case sensitivity, pagination/limits, or what a result item contains. The absence of any output schema makes this gap more significant.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
