domains_getDomainListV1

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

No annotations provided. The description correctly implies a read-only operation with no side effects. It adds no behavioral details beyond the basic action, but for a straightforward list tool, it is sufficient. No contradictions.

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?

Two short sentences, no wasted words. Essential information is front-loaded.

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 no parameters, no output schema, and no annotations, the description fully captures its purpose and usage. Complete for the simplicity of the 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?

Input schema has zero parameters, so no parameter description is needed. Schema coverage is 100% by definition.

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?

Description clearly states 'Retrieve all domains associated with your account' with a specific verb and resource. It distinguishes itself from sibling tools like 'domains_getDomainDetailsV1' which retrieves details of a specific domain, and 'domains_checkDomainAvailabilityV1' for availability.

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?

States 'Use this endpoint to view user's domain portfolio,' providing clear context for when to use. Does not explicitly mention alternatives or when not to use, but the sibling tool names imply the distinction.

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