ip_nmask

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

There are no annotations, so the description carries the behavioral burden. It does disclose that this is a write operation and that confirmation is required, which is useful, but it does not explain side effects, the confirmation flow, or whether changing the netmask will disrupt connectivity.

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 with no wasted words. It front-loads the action and resource and packs the critical write/confirmation warning into a brief parenthetical.

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 mutating network command with no output schema and several confirmation-related parameters, yet the description never explains the confirmation workflow. An agent cannot determine how to obtain confirm_token or confirmation_id, making the definition incomplete for reliable 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 0%, so the description must compensate, and it largely does not. 'lan' and 'mask' are somewhat inferable from the tool's purpose, but user_code, acknowledge, confirm_token, and confirmation_id are completely unexplained.

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 starts with a direct verb 'Set' and names a specific resource, 'LAN netmask', so the tool's function is unambiguous. It is not a tautology of the tool name and stands out from the many read-only 'show_*' siblings.

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 write hint implies this is for mutating the LAN netmask rather than viewing it, but no alternatives or when-not-to-use conditions are named. An agent can infer the general use case, but not how this compares to related network configuration tools.

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