Delete Custom Url Library

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 beyond the bare verb 'delete'. It does not state that deletion is irreversible, whether in-use rules referencing the library are affected, or what permissions are required.

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 single phrase is short but under-specified rather than concise; it spends its only words duplicating the title instead of front-loading any useful information.

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 destructive operation with no annotations, an undocumented required parameter, and only an output schema to cover return values, the description is far too thin. An agent cannot call this correctly or safely on the basis of the text alone.

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 never mentions the single parameter. The agent gets no clarification of what group_id refers to (presumably a custom URL library identifier from list_custom_url_library) or how to obtain it.

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 '删除自定义网址库' is a verbatim Chinese restatement of the tool's own name/title ('Delete Custom Url Library'). It conveys the verb+resource but adds nothing an agent could not infer from the identifier, and it does not distinguish this tool from near neighbors such as delete_url_blacklist or delete_domain_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?

No when-to-use, when-not-to-use, or alternative guidance is given. There is no mention of its relationship to list_custom_url_library or add_custom_url_library, nor any prerequisite such as needing a valid library id.

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