Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the export action and formats but doesn't describe what happens during export (e.g., file generation, download initiation, content transformation), whether authentication is required, rate limits, or what the output looks like. For an export tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
