get_pptp_client_config

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

The readOnlyHint annotation correctly indicates a safe read operation, and the description does not contradict it. However, the description adds no behavioral context beyond what the annotation provides, such as what the config contains or any prerequisites, though the simplicity of a zero-parameter getter mitigates this gap.

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 and front-loaded with no verbose wording, but it is under-specified: it merely restates the tool name without earning its place by adding value. It is not excessively long, but it could be more informative without losing brevity.

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 zero-parameter getter with an output schema (shown as present in context), the description is sufficient to invoke the tool correctly. The read-only annotation and empty input schema cover the operational aspects, and the tool name disambiguates from siblings, though the description itself does not.

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 zero parameters, so the baseline score of 4 is appropriate. There are no parameter descriptions needed, and the empty schema fully covers the input surface without additional explanation required.

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 '获取 PPTP 客户端配置' translates to 'Get PPTP client configuration', which is a direct restatement of the tool name get_pptp_client_config. It provides no additional specificity or differentiation from sibling tools like get_l2tp_client_config or get_openvpn_client_config, making it a tautology.

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 gives no guidance on when to use this tool versus alternatives. It does not mention that this is for PPTP only, nor does it exclude other VPN protocol config tools, leaving the agent to infer usage from the tool name alone.

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