Get Dns Zone

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

The verb 'Fetch' indicates a non-mutating read operation, but with no annotations provided, the description does not explicitly state that there are no side effects, how results are returned, or any permission requirements. It provides basic transparency but relies on inference.

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, focused sentence that immediately states the action and object. There is no redundancy or filler, making it efficient and well-structured.

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 only one parameter and no output schema, the description sufficiently explains what the tool does and what it returns ('DNS zone records'). It lacks details on response structure or error cases, but for a simple fetch tool, these are not critical gaps.

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 only defines a 'domain' string with 0% description coverage. The description adds the constraint that the domain must be 'hosted on Subreg DNS,' which gives context beyond the schema, but it does not clarify format or assumed characteristics of the domain value.

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 states 'Fetch DNS zone records for a domain hosted on Subreg DNS,' using a specific verb (Fetch) and resource (DNS zone records). It clearly distinguishes from sibling tools like add_dns_record and delete_dns_record by focusing on retrieval.

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 context is clear: use when you need to retrieve DNS zone records for a domain. It implies a read-only operation but does not explicitly state exclusions or alternatives; however, for a simple fetch tool, the intended usage is evident.

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