profiles_create_domain

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

With no annotations, the description was expected to disclose behavioral traits such as uniqueness constraints, effect on existing domains, or required permissions. It simply states the action, leaving agents to infer consequences.

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 single sentence is under-specified rather than concise, omitting essential context. It doesn't earn its place because it adds nearly no information beyond the tool name.

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?

While an output schema exists, the description still lacks critical context such as domain naming rules, default behavior of expiration days, or what happens on duplicate creation. For a simple creation tool, this is incomplete.

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 description coverage is 0%, so the description needed to compensate by explaining parameters. It adds no information about domain_name or default_expiration_days, relying entirely on the schema's self-explanatory names.

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 action (Create) and resource (profile domain), distinguishing it from case-specific domain tools. However, it doesn't elaborate on what a profile domain is or its relationship to siblings like profiles_list_domains.

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 usage context is provided. The description doesn't mention when to create a domain versus listing or associating existing ones, nor does it specify any prerequisites or alternative tools.

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