add_url_blacklist

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'add' without describing side effects, duplicate handling, authorization needs, or how the mode parameter affects behavior. This is severely lacking 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 extremely short, which is superficially concise, but it is under-specified and omits critical details. This is not effective conciseness; it is an incomplete stub.

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?

With 6 parameters, no annotations, and a one-line description, the tool is far from contextually complete. The existence of an output schema does not compensate for missing parameter semantics, usage guidelines, or behavioral expectations.

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%, yet the description provides no information about any of the 6 parameters (url, mode, week, comment, enabled, time_range). The description fails to compensate for the undocumented schema, leaving agents without essential parameter semantics.

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 uses the specific verb '添加' (add) and the resource '网址黑白名单' (URL black/white list), clearly indicating an add operation. This differentiates it from sibling tools like list_url_blacklist and delete_url_blacklist, though it does not explicitly explain how the black/white mode is selected.

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?

There is no guidance on when to use this tool versus alternatives, nor any mention of prerequisites, constraints, or black/white selection context. The single sentence provides no usage direction.

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