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 behavioral burden, yet it discloses nothing about the mutation's effect, required permissions, whether entries take effect immediately, or what the mode/week/time_range fields mean. This is a write tool with essentially zero behavioral disclosure.

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?

It is a single short phrase, but this is under-specification rather than useful conciseness. Nothing is front-loaded because nothing beyond the bare act is stated.

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 mutation tool with no annotations and 0% schema coverage, the description is wholly inadequate; only the existence of an output schema relieves it of explaining return values, which does not offset the missing input semantics.

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 six parameters, and the description adds no meaning for url, mode, week, comment, enabled, or time_range. The critical mode parameter (apparently selecting blacklist vs whitelist) is completely unexplained, leaving the agent unable to set it correctly.

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?

States a verb (add) and a resource (URL black/white list), so the basic operation is inferable. However, '黑白名单' ambiguously conflates blacklist and whitelist without clarifying which list is modified or how, and there is no differentiation from siblings like list_url_blacklist or delete_url_blacklist.

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 gives no when-to-use guidance, no prerequisites, and does not point to the companion tools (list_url_blacklist to inspect, delete_url_blacklist to remove). Usage must be entirely inferred from the name.

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