Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden and fails to meet it. It never says whether the tool reads or modifies an existing SOP, what it returns (a rewritten SOP, a prompt, a guide?), or what "edge-case handling" means in practice; "Includes the complete prompt, usage guide, and edge-case handling" suggests a packaged template rather than an operation, leaving the agent guessing about side effects and output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
