Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the specific transformations performed (whitespace/comments removal, variable name shortening), going beyond the readOnlyHint annotation. It does not mention any caveats, but the annotation already covers non-destructiveness, so the bar is lower.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
