add_mac_group

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

With no annotations provided, the description must disclose behavioral traits, but it does not. It only says 'add' without explaining potential side effects, required permissions, or behavior on duplicate names or invalid input. This is a significant transparency gap for a mutation tool.

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 structurally concise, but it is under-specified. It provides no additional detail or context, making it more of a near-tautology than a helpful summary. The brevity does not add value beyond restating the tool's name.

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 has 3 parameters and no annotations, the description is far from complete. It does not explain the expected input format, the purpose of the group, or any behavioral nuances. While an output schema exists, the description still needs to set context for the operation, which it fails to do.

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%, and the description provides no information about the parameters (name, comment, mac_list). It does not explain the format of 'mac_list' or the meaning of 'comment', leaving the agent to guess. The description fails to compensate for the lack of schema documentation.

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 tool's function: adding a MAC address group. It uses a specific verb ('add') and resource ('MAC group'), making the primary purpose unambiguous. However, it does not differentiate from sibling tools like 'add_ip_group' or 'add_mac_access_control', so it misses the top score.

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 description offers no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, intended use cases, or scenarios where another tool would be more appropriate. It only states the bare action, leaving the agent without context for selection.

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