Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, and it does disclose one genuinely useful behavioral trait: the output is a prompt pack with examples rather than an executed analysis. However, it omits whether the tool performs any work itself, what happens if the optional query is empty, and whether the 'workflow' is static content or query-scoped. Marketing adjectives ('production-ready', 'run today') substitute for operational detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
