hosting_verifyDomainOwnershipV1

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

No annotations provided, so description carries full burden. Discloses DNS propagation delay (up to 10 minutes), explains response field 'is_accessible', and mentions the need for TXT record; no state-changing behavior hinted, but covers important behavioral traits for a verification tool.

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?

Four concise sentences, each adding unique value: purpose, usage context, response detail, propagation note, and exclusion. No redundancy or wasted words.

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 simple one-parameter tool without output schema, the description covers purpose, usage, expected response, important timing caveat, and excluded cases. No additional information needed for correct invocation.

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?

Single parameter 'domain' with schema coverage 100%. Description adds that it's for a single domain but no additional syntactic or format details beyond the schema; 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?

Clearly states the verb 'verify ownership' and the resource 'single domain', and specifies the outcome 'return the verification status'. Distinguishes from sibling tools like domains_checkDomainAvailabilityV1 by focusing on ownership for website usage.

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?

Provides explicit context: use this before using a domain for new websites. Gives actionable instructions for non-accessible domains (add TXT record and retry). Tells when not to use (skip for Hostinger free subdomains). Does not name specific alternative tools but the context is clear enough.

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