add_mac_access_control

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states the action without mentioning side effects, permission requirements, reversibility, or what happens on duplicate MAC entries. This is insufficient for a write operation with no safety hints.

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 front-loaded but severely under-specified. It does not earn its place because it provides no value beyond what the tool name implies. Under-specification is not conciseness.

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 5-parameter write tool with no annotations and zero schema-description coverage. The description is completely inadequate to guide an agent on correct invocation, parameter semantics, or side effects. An output schema exists, but it cannot compensate for the lack of behavioral and parameter context.

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 adds no information about any of the 5 parameters. The schema shows defaults like action: 'drop' and time_range: '00:00-23:59', but their meaning, allowed values, and behavior are undocumented. The description entirely fails to compensate for the lack of schema descriptions.

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 '添加 MAC 访问控制' translates to 'Add MAC access control', which clearly states the action (add) and the resource (MAC access control). It distinguishes itself from sibling tools like list_mac_access_control and delete_mac_access_control via the verb, though it lacks explicit scope or additional context.

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 versus alternatives such as add_acl_rule or add_mac_group. The description gives no context about prerequisites, use cases, or situations where a different tool would be more appropriate.

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