get_domain_options

Read-only

Retrieves the domains available for creating aliases, including the account's default alias domain and format, so you can choose where to create a new alias.

Instructions

Get the domains available for creating aliases, plus the account's default alias domain and format.

A3.7/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds real value by disclosing return content: the default alias domain and the alias format, which an agent needs to construct a valid alias. It says nothing about ordering, consistency, or whether the list is account-wide versus permission-scoped, so it is useful but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with no filler, front-loaded with the primary result (available domains) and appending the two secondary values (default domain, format). Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter read tool with no output schema, the description covers purpose and the shape of the result, which is what an agent needs to call it and use the response. Slight gap: no indication of whether the list is guaranteed non-empty or how the default is represented when unset.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, which is the baseline-4 case. The description correctly implies no filtering input is needed and instead spends its words describing what the caller receives.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Names a specific verb and resource ('Get the domains available for creating aliases') and scopes the result set to alias-eligible domains, which separates it from get_domain (single domain) and get_account_details. It stops short of explicitly naming a sibling it is not, so it is clear rather than differentiating.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: an agent can infer it is the discovery step before create_alias, since the domains are 'available for creating aliases'. There is no explicit when-to-use statement, no mention of when to prefer get_domain for a single domain's details, and no prerequisites.

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