Bring a WireGuard interface up or down

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

Annotations are sparse: readOnlyHint=false, destructiveHint=false, but no details on side effects. The description does not disclose what happens when bringing an interface up or down (e.g., potential network disruption, need for privileges) beyond the annotations. With no annotations covering effects, the description should carry more weight but only states the action.

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 short sentence, which is concise, but it lacks structure and front-loading of key details. It is not verbose, but being a tautology means it doesn't earn the space. Conciseness is fine, but the content is essentially empty.

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?

Given the tool's complexity (3 parameters, no output schema, no parameter descriptions), the description is grossly insufficient. It fails to explain what 'id' refers to, how 'interface' relates to the system, or what the expected outcome is. An agent cannot safely invoke this tool without additional context, especially since it's a mutating operation.

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 schema has 0% description coverage, and the description provides no parameter explanations. The 'action' enum is self-explanatory, but 'id' and 'interface' are ambiguous—does 'id' refer to a host, a connection, or an interface ID? The description does not clarify the distinction or requirements, leaving agents to guess.

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?

Tautological: description restates name/title.

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. For instance, there is no mention of how this relates to host selection, prerequisites like SSH connectivity, or when 'up' vs 'down' should be chosen. The description is entirely silent on usage context.

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