Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavior. It reveals that the tool returns a systemPrompt, which is a key behavioral detail. However, it does not explain what 'scholarly mode' entails, what side effects occur (e.g., losing scholarly context), or whether the tool requires any permissions. Transparency is adequate but could be richer.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
