list_certificate_packs

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

There are no annotations, so the description carries the burden. 'List' clearly indicates a read-only enumeration operation, and 'for a zone' scopes it. However, it does not disclose pagination behavior, ordering, filtering, or any details about what is returned beyond the implied list.

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?

A single, front-loaded sentence with no filler. Every word adds value: the verb, the resource type, and the scope are all necessary and present.

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 tool with one required parameter fully documented in the schema, the description is minimally sufficient for invocation. However, there is no output schema and no mention of pagination, response shape, or distinctions from related certificate tools, leaving some behavioral context missing.

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%: the sole parameter zone_id is described in the schema. The description's phrase 'for a zone' aligns with the parameter but adds no additional format, constraints, or semantic detail beyond what the schema already provides. Baseline 3 applies.

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 ('SSL certificate packs'), and a clear scope ('for a zone'). This distinguishes it from siblings such as get_certificate_pack (single-item retrieval) and list_custom_certificates (a different certificate resource type).

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?

Usage is implied rather than explicit: if an agent needs to enumerate SSL certificate packs for a zone, this is the appropriate tool. However, the description offers no explicit guidance about when to prefer this over alternatives like get_certificate_pack or list_custom_certificates.

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