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 only states the operation ('Update') but says nothing about whether changes are destructive/overwriting, whether it is a bulk operation, validation rules for new offer IDs, or possible failure modes. For a mutation tool with zero annotation coverage, this is a substantial gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
