Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It says nothing about whether regenerating overwrites existing generated artifacts or manual edits, whether it requires the workspace to be in a particular state, expected duration, or error behavior. For an action that rewrites HTML/SVG outputs, this silence is a real gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
