Add Mac Speed Limit

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether this overrides an existing MAC limit, not the units or valid ranges for upload/download_kbps, not whether the rule is active immediately, and not the permission requirements for a mutation.

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 phrase is short but that brevity comes from under-specification rather than efficiency; there is no front-loaded purpose or scope to front-load. A single noun phrase is not a useful structure for a six-parameter mutation 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 six-parameter write operation with zero annotations and zero schema descriptions, the description is completely inadequate — an agent cannot determine valid inputs, side effects, or relationships to the existing MAC speed limit rules.

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% across 6 parameters, and the description adds no parameter meaning whatsoever — mac, upload_kbps, download_kbps, comment, enabled and time_range are all unexplained in both places.

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 限速' is a direct restatement of the tool name and title ('Add Mac Speed Limit'), so it conveys no information beyond the identifier. It vaguely distinguishes MAC from the IP-based siblings, but does not say what a speed limit is applied to or how it takes effect.

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 when-to-use guidance, no prerequisites, and no mention of the alternatives (add_ip_speed_limit, list_mac_speed_limits, delete_mac_speed_limit). The agent must infer everything from the name alone.

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