Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the certificate aspects covered (expiry, chain, issuer) but does not disclose whether the tool performs a live network connection, whether it requires a host/port parameter, what happens on certificate errors, or what the output structure looks like. The description is a terse label rather than a behavioral contract.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
