Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only says 'Find text' and gives no context about whether the operation is read-only, what the search returns, whether it supports case sensitivity, or how it handles multiple matches. This is insufficient for an agent to predict the tool's behavior beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
