Add Vlan

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing. It does not say whether vlan_id must be unique, whether the change is immediate or requires a commit, whether admin privileges are needed, or what happens on conflict.

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?

Two words is short, but this is under-specification rather than conciseness - there is no front-loaded guidance to compress. There is simply nothing to structure.

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?

A mutation tool with 5 undocumented parameters, no annotations, and a non-trivial required triple (vlan_id, name, interface) needs far more than a two-word label. The output schema covers return format, but all input and behavioral context is absent.

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% across 5 parameters (vlan_id, name, interface, ip, comment), and the description adds no parameter meaning at all. The agent gets no format, range, or relationship information for any of them.

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 '添加 VLAN' merely restates the tool name and title in another language. It conveys the bare verb+resource (add a VLAN) but nothing about scope, target device, or how it differs from the many other add_* configuration tools in the sibling set.

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 when-to-use guidance, no prerequisites, and no reference to the obvious alternatives (list_vlan_configs, delete_vlan, list_wireless_vlans). The agent must infer entirely from the name that this creates a VLAN rather than modifying or querying one.

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