Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. It clearly states that a publication is deleted from the user's LinkedIn profile, which conveys the destructive nature. It does not mention irreversibility, permissions, or effects on the public profile, but the basic behavior is unambiguous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
