Get WireGuard client

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

Annotations already declare readOnlyHint: true, covering the safety profile. The description adds the scoping promise of 'full details' and 'single', but does not disclose return format, pagination, error behavior, or authentication requirements, providing limited additional behavioral transparency.

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 sentence of eight words, front-loaded with the verb 'Get', and contains no filler words. Every word contributes to understanding the tool's purpose.

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 single-parameter read tool with a read-only annotation, the description is mostly adequate. It clearly states the operation and scope, though 'full details' is vague and there is no output schema to define the return structure. Still, the context is sufficient for an agent to select the tool correctly.

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 only parameter clientId is fully described in the schema with a type, range, and a cross-reference to list_clients, giving 100% schema coverage. The description adds no parameter-specific semantics, so baseline 3 applies.

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 uses the specific verb 'Get', identifies the resource as 'WireGuard client', and specifies scope with 'single', which clearly distinguishes it from list_clients and other get variants like get_client_config or get_client_qrcode.

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 implies usage for fetching a single client's details via the word 'single', but it does not explicitly state when to use this tool versus alternatives, nor does it mention exclusions or prerequisites beyond the schema's reference to list_clients.

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