create_vlan_zone

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

With no annotations, the description provides the only behavioral disclosure. It states 'Create' which implies a mutation, but it does not disclose permissions, idempotency, validation behavior, or return values. This is insufficient for a mutation tool.

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 concise sentence and is front-loaded. However, it is under-specified even for a create operation, sacrificing informativeness for brevity.

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 tool has 5 parameters, 3 required, no annotations, and no output schema. The one-sentence description does not explain the expected behavior, return value, or relationships to other entities, making it incomplete for reliable invocation.

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 only 20% (only vlan_id_ranges has a description). The tool description does not mention any parameter semantics, leaving the agent to infer meaning from parameter names alone. This fails to compensate for the low schema coverage.

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 identifies the action (Create) and the resource (VLAN Zone), distinguishing it from sibling operations like list_vlan_zones, get_vlan_zone, update_vlan_zone, and delete_vlan_zone. However, it lacks additional scope or detail that would elevate it to a perfect score.

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 on when to use this tool, prerequisites, or alternatives. While it is implicitly the create operation for VLAN Zones, the description offers no context for an agent selecting between CRUD tools.

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