Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that content is stored, which implies persistence, but doesn't specify where or how. It also mentions the API key fallback to environment variables, which is useful context. However, it lacks critical behavioral details like rate limits, error handling, authentication requirements beyond the API key, or what happens if scraping fails for some websites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
