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

Annotations already declare that this mutates state (readOnlyHint=false), is idempotent, and is non-destructive. The description adds that it triggers a fresh DNS lookup and only verifies on success, but omits what happens on failure (error vs. staying unverified), propagation timing, and any rate limits.

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?

A single front-loaded sentence with no wasted words. It is efficient, though arguably too terse to carry the behavioral detail a state-changing verification tool needs.

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?

There is no output schema, so the description should say what the caller gets back — e.g., verified status, whether it returns the updated domain object, or error behavior when records are wrong. The conditional 'verifies it if they are correct' hints at this but leaves the failure path unspecified.

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 coverage is 100%, with orgId and domainId fully documented including their source tools, so the schema carries parameter semantics. The description adds nothing about parameters; baseline 3 is appropriate.

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?

States a specific verb (re-checks/verifies) and resource (domain DNS records), and clarifies that verification is conditional on records being correct. It is distinguishable from domain_get and domain_list, though it doesn't name the boundary explicitly.

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 — an agent can infer you call this after configuring DNS records. No explicit when-to-use/when-not-to-use guidance, no mention of alternatives like domain_get for a read-only check, and no prerequisites stated.

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