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 the action (adding a table) but doesn't cover critical traits: whether this is a mutation (likely yes, but not confirmed), permission requirements, effects on the document (e.g., overwriting content), error conditions, or response format. For a tool with 5 parameters and no annotations, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
