msubnet_status

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

With no annotations present, the description carries the full burden of behavioral disclosure. It does state 'read-only', which tells the agent the operation will not modify state, but it says nothing about output format, potential latency, privilege requirements, or whether the status is collected from multiple sources. This is a minimal but real behavioral disclosure.

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 one short phrase with no filler. It front-loads the resource name and the key read-only trait, making it appropriately concise for a zero-parameter status tool.

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 parameterless read-only status tool, the description is minimally acceptable, but it does not explain the return value shape or what 'multi-subnet status' actually includes, and it provides no context for choosing this status tool over the many sibling status tools. The absence of an output schema makes this gap more noticeable.

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 input schema has zero parameters and schema description coverage is 100%, so there are no parameter semantics for the description to clarify. The baseline for zero-parameter tools applies here, and the description adds no unnecessary parameter-related text.

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 identifies the resource as multi-subnet and labels the operation as read-only status, which is minimally clear. However, it lacks an explicit verb like 'show' or 'return' and does not explain what data the status contains, so it only weakly differentiates from the many other status tools in the sibling list beyond the multi-subnet qualifier.

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 given about when to use this tool versus alternatives. The 'read-only' label implies it is for inspection rather than configuration, but no explicit context, exclusions, or alternative tool references are provided, leaving the agent to infer usage purely from the name.

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