Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false, so the burden is somewhat lower, but the description adds nothing about what an 'import' does—what gets created, whether it overwrites a library, permissions or auth needed, or side effects. It also does not clarify the meaning of the free-form 'body' payload, which is central to this write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
