list_origin_ca_certificates

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

No annotations are provided, and the description simply restates the list operation without adding behavioral context. It does not mention pagination, ordering, whether expired or revoked certificates are included, or any other behavior beyond listing.

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, front-loaded sentence with no filler words. 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?

For a one-parameter list operation, the description provides the essential invocation details. Pagination and response behavior are not described, but the simplicity of the tool and full schema coverage make the description adequate.

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 coverage is 100%, and the zone_id parameter already includes a description. The tool description adds only the contextual phrase 'for a zone' and does not materially extend the parameter semantics provided by the schema.

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 verb (List), a specific resource (Origin CA certificates), and the scope (for a zone). It clearly distinguishes this tool from sibling certificate-related tools such as list_custom_certificates and list_certificate_packs.

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 intended use is implied by the resource name and zone scope, but there is no explicit guidance about when to choose this tool over alternatives like list_certificate_packs or list_custom_certificates. No exclusions or routing hints are provided.

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