domains_getWHOISProfileUsageV1

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

No annotations are provided, so the description bears full responsibility. It describes a read operation to retrieve a list, but doesn't disclose response format, pagination, or any side effects. It adds basic behavioral context but could be more detailed.

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, front-loading the purpose and then adding usage context. Every sentence is necessary and concise.

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 no output schema, the description could hint at what the response contains (e.g., domain names or IDs). It only says 'domain list', which is adequate but not fully complete for a simple tool.

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 only parameter 'whoisId' is described in the schema as 'WHOIS ID', and the description adds no further meaning. With 100% schema coverage, baseline is 3, and no extra value is provided.

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 'Retrieve domain list where provided WHOIS contact profile is used', specifying the verb, resource, and condition. This distinguishes it from sibling tools like domains_getWHOISProfileListV1 (lists profiles) and domains_getWHOISProfileV1 (gets single profile).

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 says 'Use this endpoint to view which domains use specific contact profiles', indicating the appropriate scenario. While it doesn't explicitly list when not to use or provide alternatives, the context of siblings implies the proper use.

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