list_dns_firewall_clusters

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention pagination, response shape, ordering, or any side effects or read-only guarantees. The description is accurate but provides no behavioral context beyond the basic listing operation.

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 short sentence with no wasted words. It is front-loaded with the action and resource. However, it is so minimal that it could have used a bit more context without becoming verbose.

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 simple one-parameter list operation, the description is minimally adequate. It correctly identifies the resource and scoping argument, but it leaves out useful contextual details such as what the response contains or whether results are paginated. Given the absence of an output schema and annotations, this is a noticeable 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 100% because account_id is fully described as 'The account ID'. The description adds minimal context by indicating the clusters are scoped to an account, but it does not meaningfully enhance the parameter understanding beyond 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 clearly states a specific verb ('List') and resource ('DNS Firewall clusters'), scoped to an account. It does not explicitly differentiate from the sibling get_dns_firewall_cluster, but the list-versus-get distinction is readily apparent from the resource name and description.

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?

No guidance is given about when to use this tool versus alternatives like get_dns_firewall_cluster or get_dns_firewall_analytics. The description only states what it does, not when it should be chosen over other cluster-related tools.

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