get_domain

Read-only

Retrieve details for a specific domain by ID, including verification status, DNS records, and provider connections.

Instructions

Get details of a specific domain by ID, including verification status, DNS records, and provider connections.

ACCESS: needs a Proof account. Set PROOF_API_KEY and restart this server, or sign in with start_login — a session opens this tool — then call this tool again.

TDQS

A3.7/5.0

Behavior4/5

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

The readOnlyHint annotation already establishes the safety profile, and the description adds genuinely useful context beyond it: the required Proof account, the PROOF_API_KEY environment setup, and the start_login session path before retrying. It also previews the kind of data returned, which helps an agent anticipate the shape of the response.

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

Conciseness4/5

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

The core purpose is front-loaded in one sentence, and the access block is separated out so it does not obscure the main function. The access note is somewhat verbose (mentioning both the env-var route and the start_login route), but every sentence carries actionable information.

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?

With an output schema present, the description needn't explain return values, yet it still summarizes them. Auth prerequisites — the most likely failure mode for a fresh agent — are fully covered. The only gap is the absence of guidance on how this relates to sibling domain tools.

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

Parameters3/5

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

There is a single required parameter with 100% schema description coverage, so the schema already carries the semantics. The description's phrase "by ID" confirms the parameter is a domain identifier rather than a name or hostname, but adds no format or lookup detail beyond that. Baseline 3 applies.

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?

The description names a specific verb and resource ("Get details of a specific domain by ID") and enumerates the returned facets (verification status, DNS records, provider connections), which distinguishes it from list_domains, delete_domain, and verify_domain. It stops short of explicitly naming the sibling tools it is not.

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 implied by "by ID" — you need a known domain ID — but there is no explicit statement of when to reach for this versus list_domains or the various verify/check domain tools. The access paragraph covers prerequisites for calling it, not selection guidance among alternatives.

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