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

The annotations declare readOnlyHint=false, idempotentHint=false, destructiveHint=true and openWorldHint=true, and the description usefully explains the non-read-only side effect: setting check: true starts a new round of DNS checks, which also accounts for non-idempotency. However, it does not explain the destructiveHint=true annotation at all (nothing here suggests something is destroyed), nor any permission, propagation-delay, or rate-limit behavior around re-triggering checks, so a meaningful behavioral gap remains.

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?

Two compact sentences with no filler, and the primary outcome (connected vs. DNS records to add) is front-loaded ahead of the flag behavior. The phrasing is slightly oblique ("How a site's domain stands") where a plain verb would be clearer, but nothing is wasteful.

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?

For a two-parameter tool with no annotations-level detail about returns, the description does sketch the response (connection state or pending DNS records), which is helpful. It still leaves out what the site parameter accepts, why the call is flagged destructive, and what the result looks like after a forced re-check, so it is adequate rather than complete.

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 is the only source of parameter meaning. It does credibly explain the check flag (boolean that initiates a fresh DNS check round), but the required site parameter is never defined — the reader must assume it is a site identifier or hostname — and the description does not clarify whether site is an ID, a domain string, or a site handle.

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 conveys the resource and outcome well enough: it reports whether a site's domain is connected or which DNS records remain outstanding, and notes the check flag triggers a new round of DNS checks. It is not a crisp verb+resource statement ("How a site's domain stands" is idiomatic rather than explicit), and it never names connect_domain as the adjacent tool, so an agent has to infer the boundary itself.

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?

Usage is only implied. The description explains that check: true re-runs DNS checks, which hints at when to set it, but gives no guidance on when to omit it, no statement of prerequisites (e.g. a domain must already be added via connect_domain), and no exclusions against sibling tools like connect_domain or site_status.

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