get_dns_zone_file

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds value by disclosing that the output is a BIND-format zone file, which is a useful behavioral trait. However, it does not mention potential size concerns, response format specifics, or any other side effects, so it adds only modest context beyond the annotation.

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 names the action, resource, format, and scope with zero fluff. Every word contributes to usability, making it an exemplar of concise structure.

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 one-parameter, read-only tool with no output schema, the description covers what is returned (BIND-format zone file) and the required input (specific zone). It is sufficient for correct invocation, though it could mention whether the zone file is returned as a raw string or with any special encoding.

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 100% description coverage for the single parameter zone_id ('the ID of the DNS zone'). The description adds no additional meaning for the parameter, so the baseline of 3 applies per the scoring rubric.

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 a specific verb ('Get') and resource ('zone file') with an explicit format qualifier ('BIND format'), and scopes it to a specific DNS zone via zone_id. This distinguishes it from sibling tools like get_dns_zone (metadata) and list_dns_zone_records (individual records), so an agent can identify the right tool.

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 gives no explicit guidance on when to use this tool versus alternatives such as get_dns_zone or list_dns_zone_records. It only implies the tool is used for the full BIND-format zone file, but there is no when/when-not or alternative routing, leaving the selection entirely to the agent's inference.

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