Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description itself must disclose side effects, and it does: it states that writing all queued edits into code and refreshing every Figma screen from code both occur. It is transparent about scope ('all queued', 'every screen') and about the fact that both code and Figma are mutated. It does not mention reversibility, permission requirements, or failure modes, but for a zero-parameter action the core behavioral contract is clear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
