Get Zone

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

With no annotations provided, the description carries the burden of conveying behavior. The verb 'Get' clearly implies a read-only operation, and 'by ID' scopes the request. However, it does not state explicit behavioral details like non-mutation, error behavior, or authentication needs, though the output schema covers return structure. This is adequate but not rich.

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 one sentence, front-loads the key purpose, and contains no filler or repetition. Every word 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?

For a simple get-by-ID tool with one parameter and an output schema, the description provides enough context for an agent to understand what the tool does and how to invoke it. It could mention when to use list_zones instead, but the tool's simplicity and the provided schema make it nearly 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?

Schema description coverage is 0%, so the description must compensate. It does clarify that the single parameter is the zone's ID and ties it to 'a specific Cloudflare zone,' which adds minimal meaningful context. It does not explain the expected format, how to obtain the ID, or edge cases, leaving it barely sufficient.

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'), a specific resource ('a specific Cloudflare zone'), and the key qualifier 'by ID,' which distinguishes it from list_zones and get_zone_settings. An agent can immediately understand what this tool does and how it differs from its siblings.

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 implies usage: use this when you have a zone ID and need details for a single zone. However, it does not explicitly contrast with list_zones or explain when to prefer one over the other, leaving the routing decision mostly to inference.

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