create_interface_group

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is clear. The description adds no extra behavioral context (e.g., that changes may require a separate apply step, or that members must be valid interfaces), leaving the agent without information about side effects beyond the raw create 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 minimal and front-loaded, but it under-specifies the tool. It is not so much concise as sparse, omitting useful context about the configuration change or how to verify success.

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?

With an output schema present, return values are presumably covered, but the description lacks information about when to use this tool, what conditions must hold (e.g., interfaces must exist), and whether apply_immediately is required. It is too bare to be considered complete for a create 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?

Schema description coverage is 100%, and each parameter has a clear description (ifname, members, descr, apply_immediately). The tool description itself adds no additional parameter semantics, so the baseline of 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 clearly states the action 'Create' and the resource 'interface group', which is specific enough to distinguish it from sibling tools like create_interface_bridge. However, it does not elaborate on what an interface group is or when it differs from other creation tools.

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 instead of alternatives such as create_interface_bridge or apply_interface_changes. The description lacks any context about prerequisites, use cases, or when this tool is preferred.

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