zones_create

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

No annotations provided, so the description carries the full burden. It discloses that the tool is a write operation and requires a confirmation parameter, which is good. However, it does not discuss rate limits, error behaviors, or idempotency, leaving some behavioral aspects unclear.

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 sentence with a brief note about requirements. It is front-loaded with the action and includes only necessary information. No wasted words.

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 description is incomplete for a creation tool with no output schema. It does not explain the expected structure of the JSON body or what the response contains. Missing guidance on the zone resource format.

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 100%, so each parameter is already described. The description adds no new semantic information beyond what the schema provides (e.g., it repeats 'bodyJson' as a JSON string). The baseline of 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 clearly states 'Create a new GTM zone' with a specific verb and resource. It distinguishes from sibling tools like zones_list or zones_update by explicitly indicating creation.

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 mentions prerequisites (GTM_MCP_ENABLE_WRITES=true and confirm=true) but provides no explicit guidance on when to use this tool versus alternatives like zones_update or zones_delete. The context is clear but lacks exclusions.

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