Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral burden; it does disclose the resulting state (condition = 2) and that the card is not removed, which is genuine non-destructive context. It says nothing about permissions, whether archiving is reversible/unarchivable, or what happens if the card is already archived.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
