Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description only says 'Open... via ИЗменить форму' without disclosing side effects, prerequisites, or failure modes. With no annotations, this minimal statement carries the full burden of behavioral disclosure and is insufficient for an agent to understand whether it changes UI state, requires a focused form, or can fail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
