Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It states 'Create or update', which implies mutation, but it does not explain whether the tool overwrites existing files, how conflicts are handled, whether it requires specific permissions, or what the response contains. The description adds minimal behavioral context beyond the action itself, which is a significant gap for a write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
