add_vlan

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. '添加 VLAN' implies a mutation (creating a resource) but does not mention side effects, required permissions, duplicate handling, or reversibility. This is a significant gap for a write operation.

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, short sentence that directly states the action. It is concise and front-loaded, with no unnecessary words. However, it is so brief that it sacrifices useful context, so it doesn't earn a perfect 5.

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 create operation with five parameters (three required), no annotations, and no behavioral details, the description is drastically incomplete. The output schema exists but doesn't compensate for the lack of usage context. This description provides almost no actionable guidance for an agent.

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?

The input schema has five parameters with zero description coverage. The description adds no meaning beyond what parameter names (vlan_id, name, interface, ip, comment) already suggest. It fails to clarify the purpose of fields like 'interface' or 'ip' in the VLAN creation context, leaving the agent to guess.

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' (Add VLAN) uses a specific verb and resource, clearly indicating a create operation. It distinguishes itself from sibling tools like list_vlan_configs and delete_vlan since 'add' is unique among them, but it lacks any additional scope or detail that would push it to a 5.

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 alternatives. There is no mention of prerequisites, exclusions, or context such as 'use this to create a new VLAN before configuring DHCP.' It simply states the action without any situational advice.

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