Check a custom domain

check_custom_domain
Read-only

Check whether a custom domain's subdomains are live: re-polls Cloudflare cert status + probes DNS/TLS/HTTPS on each subdomain. Poll this after connect_provider / add_subdomain to confirm the domain is serving. Returns per-subdomain status + tls + http + ready.

TDQS

A4.7/5.0
Behavior5/5

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

Description adds significant behavioral context beyond annotations: re-polls cert, probes DNS/TLS/HTTPS, and returns per-subdomain status. No contradiction with read-only and open-world hints.

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?

Two sentences with no filler. Front-loaded with main action, then additional context. Every word earns its place.

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

Completeness5/5

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

Given one required parameter, annotation hints, and existence of output schema (not shown), the description covers what it does and what it returns. No gaps for typical usage.

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?

Single parameter with schema providing description and example. The description repeats the parameter purpose but adds no extra semantics beyond the schema; however, the example is helpful. With 100% schema coverage, baseline is 3, so 4 for the example.

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

Purpose5/5

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

The description clearly states it checks if a custom domain's subdomains are live, with specific actions (re-polls Cloudflare cert, probes DNS/TLS/HTTPS). It distinguishes from siblings like check_domain by mentioning it is used after connect_provider/add_subdomain.

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

Usage Guidelines4/5

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

Explicitly says to poll after connect_provider or add_subdomain to confirm domain is serving. While it doesn't list when not to use or alternatives, the context is clear.

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