get_dns_record

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

With no annotations, the description must fully disclose behavior. It only states 'Fetch a single DNS record', which implies read-only, but does not mention permissions, rate limits, or potential errors. The disclosure that it uses 'Porkbun's record id' is helpful but insufficient for a complete behavioral understanding.

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, concise sentence that front-loads the action and resource. Every word is necessary and there is no extraneous information.

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?

The tool is simple with 2 parameters and no output schema. The description gives the core purpose but lacks details about return values, prerequisites (e.g., domain ownership), or error conditions. For a minimal tool, it is adequate but not fully 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 schema has 0% description coverage. The description adds meaning to the record_id parameter by specifying 'Porkbun's record id', but does not elaborate on the domain parameter (e.g., format, example). This partially compensates for the lack of schema descriptions, yielding a baseline score of 3.

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 explicitly states the action 'Fetch' and the resource 'a single DNS record', and specifies the unique identifier 'Porkbun's record id'. This clearly differentiates it from sibling tools like list_dns_records or get_dns_records_by_name_type.

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 guidance is provided on when to use this tool versus alternatives. For example, it does not mention that you need a specific record ID, or that you might need to retrieve it first via list_dns_records. There is no when-to-use or when-not-to-use context.

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