agency-hosting_listAvailableDatacentersForAnAgencyPlanOrderV1

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

No annotations are provided, so the description carries the full burden. It explains that each datacenter includes a pinger_url for latency measurement, and how to use it to select the nearest datacenter. This provides useful behavioral context beyond basic functionality, though it doesn't detail response structure or limitations.

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 two sentences, each serving a distinct purpose: stating the action and providing actionable guidance on the output. No fluff, well-structured, and easy to parse.

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?

Given the single required parameter and no output schema, the description provides sufficient context for an AI agent to understand what the tool returns (datacenters with pinger_url) and how to use it. It could be improved by specifying the response structure, but it still connects well to related tools like provisioning.

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?

The single parameter order_id is well-described in the schema as 'Agency Plan order ID', and the description reinforces it by mentioning 'given Agency Plan hosting order'. With 100% schema coverage, the description adds marginal value, but it does tie the parameter to the broader purpose.

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 the tool lists datacenters for provisioning a new website on an Agency Plan hosting order. It uses a specific verb ('Lists') and resource ('datacenters available for provisioning'), distinguishing it from sibling tools like 'hosting_listAvailableDatacentersV1' which is for regular hosting.

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 usage before creating a website to select a datacenter, and provides guidance on using the pinger_url to pick the nearest one. It does not explicitly state when not to use it or name alternatives, but the context is clear given the sibling tool for regular hosting.

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