get_device_interfaces

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds no further behavioral context such as return format, pagination, or filtering behavior, but for a simple read-only getter this is minimally adequate.

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 terse sentence with the verb and object front-loaded and no filler. The parenthetical '(resource)' is slightly redundant, but it does not meaningfully detract from clarity.

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?

This is a simple one-parameter, read-only tool whose safety characteristics are already covered by annotations, so the description does not need to be elaborate. However, with no output schema and no mention of what data is returned, an agent cannot predict the response shape before invocation.

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 the only parameter, device_id, is already documented as 'Device ID'. The description merely references 'a device' and adds no meaning beyond what the schema provides, so it meets but does not exceed the baseline.

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 a specific verb 'Get' and a clear resource 'network interfaces for a device', making the tool's purpose obvious. It is distinguishable from sibling getters like get_device, get_device_datasources, and get_device_connections without needing to inspect schemas.

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 about when to use this tool versus alternatives such as get_device_connections or get_interface_metrics. The agent is left to infer the appropriate context from the tool name alone, with no exclusions or conditions stated.

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