Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false, suggesting this is a mutation tool (conversion), which aligns with the description's 'convert' action. The description adds minimal behavioral context beyond annotations—it specifies the input format but does not detail output behavior, error handling, or constraints like command complexity limits. With annotations covering the mutation hint, a baseline score of 3 is appropriate as the description adds some value but lacks rich behavioral details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
