get_dns_zone

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

The description is consistent with the readOnlyHint annotation, stating a read operation. It adds minimal behavioral context beyond the annotation, such as that it targets a specific zone, but does not disclose return format or any additional behaviors. Since annotations already cover the read-only nature, this is acceptable but not enriched.

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, clear sentence with no filler. It front-loads the action and resource and earns its place.

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?

Given the low complexity (one required parameter, no output schema, read-only annotation), the description is mostly complete. However, 'details' is somewhat vague and could specify what kind of details are returned, though this is a minor gap for such a simple get-by-ID tool.

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 coverage is 100% for the single zone_id parameter, and the schema describes it as 'the ID of the DNS zone'. The description only implies the parameter via 'specific DNS zone', adding no new semantic information. 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 states a clear verb ('Get') and resource ('DNS zone') with the qualifier 'specific' to indicate retrieval by ID. This distinguishes it from sibling list operations like list_dns_zones and from other get_* tools for different resources (e.g., get_dns_record).

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 about when to use this tool versus alternatives. It does not mention that a zone_id must first be obtained, nor does it reference sibling tools like list_dns_zones for discovery. The agent must infer usage from the schema and tool name.

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