Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint, destructiveHint=false and openWorldHint=false, so the safety profile is largely covered. The description usefully discloses that the output is an HTML artifact and that the return value is a path, but it omits where the file is written, whether an existing file is overwritten, and any size/time cost. The 'Write' verb sits in mild tension with readOnlyHint=true, though for an export tool the write is artifact generation rather than mutation of the source snapshot.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
