Get Video Ads domain

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the '[READ]' tag adds nothing beyond structured data. No behavioral context is supplied about what the domain resource contains, whether the read is scoped to an account, or what the response shape is.

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?

It is a single short token string with no filler, so there is nothing to trim. However, the extreme brevity reflects under-specification rather than disciplined conciseness, since no informative content 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?

The operation is simple (no params, no output schema), which lowers the bar, but the description still leaves the agent unable to tell what resource is fetched or how it differs from the many sibling domain getters. Even one clause describing the returned VADS domain object would close the gap.

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 tool takes zero parameters and the schema is fully covered at 100%, so there are no parameter semantics for the description to clarify. Baseline 4 applies for a parameterless operation.

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 essentially restates the name and title, mapping them to an HTTP method and path ('[READ] OpenAPI: GET /domain'), without explaining what a VADS domain is or what the call returns. It gives no basis for distinguishing this from sibling reads like get_vod_domain, get_live_domain, or get_domain.

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?

There is no when-to-use guidance, no mention of prerequisites, and no reference to any alternative sibling tool. The agent is given nothing to decide when this call is appropriate.

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