get_domain_records

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

Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is fully declared. The description adds context about the specific record types returned but does not disclose any additional behavioral traits such as required permissions or response structure.

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?

The description is a single sentence containing 16 words, listing examples in parentheses. Every word is informative, no redundancy. It is appropriately front-loaded and concise.

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 read operation with one parameter, the description covers the core purpose. However, it omits details about the output format (no output schema) and does not explicitly state that the domain must already exist. Sibling tool names partially compensate for context, but the description could be more 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?

The input schema has one parameter 'name' with zero description coverage (0%). The tool description does not clarify that 'name' likely refers to the domain name, nor does it add any semantics beyond the schema. The agent may not infer the correct parameter meaning.

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 clearly states the tool retrieves DNS records (MX, SPF, DKIM, DMARC, verification) for domain setup. It uses a specific verb ('Get') and resource ('DNS records'), and its purpose is distinct from sibling tools like get_domain or get_domain_diagnostics.

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?

The description implies usage for domain setup but provides no explicit guidance on when to use this tool vs alternatives (e.g., get_domain for general info, get_domain_diagnostics for troubleshooting). No prerequisites or exclusions are mentioned.

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