Toggle Vpn Server

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only restates the toggle. It does not say whether disabling drops connected clients, whether the change persists across reboot, what permissions are required, or what the response contains — all material 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?

It is a single short sentence with no padding, so it is efficient, but the extreme brevity here reflects under-specification rather than disciplined conciseness. Front-loading is fine; content is what is missing.

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?

An output schema exists, so return values need not be described. However, for a two-parameter, zero-annotation mutation tool with no schema descriptions, the description leaves the agent without enough to invoke it confidently — particularly the vpn_type domain and side effects.

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% for both required parameters. The phrase 'enable/disable' loosely maps to the boolean 'enabled', but 'vpn_type' is left completely unexplained — no list of accepted values (e.g. PPTP/L2TP/OpenVPN/IKEv2) even though sibling tools imply several exist.

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 pairs a specific verb (enable/disable) with a specific resource (VPN server), so the operation is unambiguous. It does not, however, differentiate itself from nearby siblings such as toggle_pppoe_server, toggle_web_auth, or list_vpn_servers, leaving the agent to infer which toggle family applies to which object.

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?

There is no guidance on when to use this tool versus list_vpn_servers (to inspect state first) or the client-side VPN tools. No preconditions, no warnings about toggling an already-enabled server, and no mention of which vpn_type values are valid.

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