unifi_gen_createfirewallzone

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is covered structurally. The description adds only a vendor documentation URL and does not explain permissions required, the effect of creating a zone, or how confirm/dry_run alter behavior beyond what the schema already states.

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 with no wasted prose. It is appropriately sized, though extremely terse for a destructive creation tool.

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 a destructive firewall-zone creation tool with rich annotations and a fully documented schema, the description covers the basic action and points to vendor docs. It still omits sibling differentiation and any operational context about what a firewall zone is or when this generated variant should be chosen.

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 the schema already documents the body, confirm, and dry_run parameters in detail. The tool description itself adds no parameter meaning beyond the high-coverage schema, making the baseline 3 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 specific verb and resource: “Create Custom Firewall Zone.” It is clear what operation is performed, but it does not distinguish this tool from sibling firewall-zone creation tools such as unifi_net_create_firewall_zone or explain its generated-API nature beyond the URL.

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 provides no guidance on when to use this tool versus the many sibling firewall-zone tools. It does not mention prerequisites, alternatives, or the distinction between generated and non-generated API tools.

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