Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description alone carries the burden. It discloses parallel execution and that files do not pass through the context, which is useful. However, it omits many behavioral traits: required permissions, file size limits, supported formats, whether it's read-only (likely safe), or error behavior. The disclosure is insufficient for safe and correct invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
