Verify Domain

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

Annotations already state readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the safety profile is partly covered. But the description adds nothing about what verification does — whether it triggers an async DNS/ownership check, requires prior domain configuration, consumes a quota, or returns only an acknowledgement. That is a significant omission for a non-idempotent write action.

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 words, so nothing is wasted, but this is under-specification rather than conciseness. There is no front-loaded context an agent could act on.

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?

With no output schema and a non-idempotent, non-read-only action, the description should explain the outcome or side effect of verification. It says nothing, so the agent must invoke blind — annotations and the fully documented parameters only partly compensate.

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 100% and both required parameters (providerId, domainId) are documented in the schema, so the baseline of 3 applies. The description adds no extra meaning about how these identifiers scope or constrain the verification.

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?

Tautological: description restates name/title.

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?

No when-to-use guidance is given, no prerequisites, and no mention of any sibling tool. With providers_domains_get and providers_domains_add in the same family, the agent has no basis for choosing this one.

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