gatekeeper_check_certificate_status

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering safety. The description adds the domain-specific semantic but does not disclose additional behavioral context such as whether a network lookup is performed, what response is expected, or edge cases like invalid domains. It is not misleading, but adds little beyond the annotations and tool name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear, front-loaded sentence with no filler words. It is appropriately sized for a simple check tool and every word contributes to the meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the agent is left without any indication of what the tool returns: a boolean, a status string, certificate details, or an error object. The description also does not mention whether 'installed' means locally configured, publicly valid, or resolvable via DNS. For a status-checking tool, this missing output information is a significant gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, but it only tells the agent that the check is 'for a domain'. It does not clarify expected format (e.g., bare domain, with protocol, www vs non-www), whether IP addresses are accepted, or how the domain argument affects the certificate lookup. The schema already labels the parameter as 'Domain', so the description adds almost no semantic value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Check whether') on a specific resource ('an SSL certificate') scoped to 'a domain'. This cleanly distinguishes it from sibling tools like gatekeeper_install_certificate, gatekeeper_remove_certificate, and gatekeeper_list_certificates, since it focuses on existence/status for one domain rather than management or listing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use is appropriate when verifying whether a domain has a certificate installed, but it does not explicitly mention alternatives or when not to use it. No direct reference is made to gatekeeper_list_certificates or gatekeeper_install_certificate, so the guidance is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
