vpn_connect

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. It merely says 'Connect VPN' and gives no information about side effects, required permissions, what happens on success/failure, or connection lifecycle. This is a significant transparency gap for a state-changing 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?

The description is extremely short, but this is under-specification rather than conciseness. It has no structure and fails to carry useful information, making it a low-quality minimal entry.

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?

This tool has four parameters, no output schema, and no annotations. The description is a two-word tautology that provides no operational context, no parameter explanation, no return value expectations, and no behavioral details. It is completely inadequate for an agent to use this tool effectively.

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 does not mention any of the four parameters (vpn_type, socks_port, config_file, enable_socks). The description provides no semantic meaning beyond the raw schema, so the agent cannot infer what values to supply or how the parameters influence behavior.

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?

Description 'Connect VPN' merely restates the tool name 'vpn_connect' in sentence form, making it tautological. It does not add any detail about the VPN type, configuration, or behavior beyond what the name already implies, and it fails to distinguish from siblings like vpn_disconnect or vpn_status beyond the basic action.

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 alternatives. It does not mention prerequisites, typical scenarios, or how it relates to vpn_disconnect or vpn_status. The description provides no context for selection.

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