list_ip_prefixes

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, but it only restates the listing action. It does not mention pagination, the shape of the returned data, read-only safety, or any account-level prerequisites beyond the required parameter.

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 one short sentence with no filler. It front-loads the action and resource and keeps the BYOIP clarification minimal and useful.

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 list operation with one fully documented parameter, the description is mostly sufficient for an agent to invoke the tool. The only minor gap is that it does not explicitly state the output format or pagination behavior, but these are relatively predictable for a list endpoint.

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 single account_id parameter is already documented as 'The account ID'. The description adds nothing beyond that, so the baseline of 3 is appropriate.

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 uses a specific verb ('List'), names the resource ('IP prefixes'), and clarifies scope ('for an account') plus the BYOIP context. It clearly separates this from sibling tools like get_ip_prefix (singular) and list_ip_prefix_delegations.

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 related siblings such as get_ip_prefix or list_ip_prefix_delegations. The intended context is only implied by the name and the single scope qualifier, with no explicit when/when-not statements.

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