Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It discloses an important behavioral nuance: 'granting one never widens another' regarding consent classes. However, it does not explain the effects of granting (e.g., whether it's reversible, what changes occur, or any prerequisites), leaving notable gaps for a mutation-type tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
