Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of disclosing behavior. 'Install' implies a system modification, but the description does not mention side effects, permissions required, whether the installation is silent, or what happens if the plugin already exists. The 'force' parameter hints at reinstallation behavior, but the description itself provides no transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
