Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full burden. Instead of disclosing what the tool generates, whether the output is a prompt vs. an analysis, whether it requires a brand or restaurant name, or what the response looks like, it offers benefit claims. The phrase 'prompt and operating playbook' even muddies what the returned artifact actually is.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
