Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only states that the tool shows or submits a survey, but it does not disclose what side effects occur (e.g., interrupting the user, opening UI, permanently submitting responses), whether the operation is idempotent, or what happens if no survey is assigned. This is insufficient for a tool that appears to have user-facing effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
