toggle_vpn_server

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states 'enable/disable' without explaining effects on existing VPN connections, whether the change is persistent, or what happens to clients. This is a minimal mutation disclosure with no additional detail.

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 with no filler words, which is structurally efficient. However, it is under-specified rather than effectively concise, so it does not earn a 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?

With no annotations, no parameter descriptions, and an ambiguous 'VPN server' resource, the description is inadequate for correct invocation. It does not address which VPN type to target, when toggling is appropriate, or what the output schema contains, making it minimally useful.

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% and the description provides no information about the vpn_type or enabled parameters. vpn_type is a required string with no accepted values or enum guidance, and enabled's boolean semantics are not described, leaving the agent without necessary parameter context.

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 '启用/禁用 VPN 服务端' clearly states a specific action (enable/disable) and resource (VPN server). However, it does not differentiate among VPN protocol types or distinguish itself from sibling tools like toggle_pppoe_server, so it falls short of 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?

No usage context or guidance is provided. The description does not explain when to use this tool versus alternatives, mention prerequisites, or clarify what vpn_type should be. Sibling tools such as list_vpn_servers and toggle_pppoe_server exist but are not referenced.

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