Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits but only states the basic execute-and-return-output behavior. It does not mention side effects, sandboxing, interpreter requirements, error handling, or whether the file is run in an isolated environment, which are important for a code execution tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
