get_vpn_client_status

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

The description includes a list of error codes, which provides some insight into possible failure modes. However, with no annotations, it does not disclose other behavioral traits such as authentication requirements, side effects, or response format.

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 concise with two sentences. The first sentence is somewhat redundant with the tool name, but the error code list provides useful information without excessive length.

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 simple status retrieval tool without parameters, the description is adequate but lacks contextual guidance to distinguish it from sibling tools like get_vpn_client_config or get_vpn_connection. The output schema exists but is not described.

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 tool has no parameters, so the description need not add parameter details. The baseline for zero parameters is 4, and the description appropriately omits parameter information.

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 states 'Get the VPNClientStatus', which clearly identifies the resource and action. However, it does not distinguish this tool from sibling tools like get_vpn_client_config or get_vpn_connection, so it lacks sibling differentiation.

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 guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or typical use cases.

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