Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden, yet it discloses nothing about what the tool actually does on invocation — whether it rewrites text, returns a static prompt template, or performs analysis. It also omits return shape, side effects, and whether any input content is transformed, leaving the agent to guess.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
