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 mentions the tool returns the output path, but does not cover permissions, whether it overwrites files, error conditions, or side effects. The mention of 'using ezjww' is implementation detail, not behavioral context an agent needs for invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
