dnsAddRecord

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action 'Add' without mentioning side effects, API constraints, authentication requirements, or error behaviors. A mutation tool should disclose more about consequences, but the description is silent beyond the purpose.

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, front-loaded sentence that states the action and includes a helpful API reference link. There is no fluff or redundancy; every element serves a purpose.

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 mutation tool with no output schema and no annotations, the description is too sparse. It does not mention required permissions, the response shape, whether the operation is idempotent, or any constraints (e.g., domain must exist). An agent may be able to call it correctly using the schema, but it lacks important behavioral and contextual details.

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%, so the schema already documents all six parameters, including rrtype enums and defaults for rrttl. The description adds no parameter-level information beyond the schema, so 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?

The description 'Add a DNS resource record' clearly states the verb and resource, making the purpose unambiguous. It distinguishes from sibling tools like dnsListRecords, dnsUpdateRecord, and dnsDeleteRecord by the action verb alone, though it does not explicitly name them.

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 provides no guidance on when to use this tool versus alternatives such as dnsUpdateRecord or dnsDeleteRecord. There is no mention of prerequisites, typical scenarios, or exclusions, leaving the agent to infer usage solely from the verb 'Add'.

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