delete_url_blacklist

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It only says 'delete' without mentioning whether the deletion is permanent, what happens to associated data, or whether specific permissions are required. This is a significant gap 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 terse (8 characters). While concise, it is under-specified and fails to provide essential information. This is not effective conciseness but rather a lack of specification, similar to the 'Process' example.

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 delete operation, the description is woefully incomplete. It lacks prerequisites (e.g., rule must exist), scope clarification (black vs. white list), and any mention of return value or error handling. Despite the low complexity, the description does not enable correct tool invocation.

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?

The input schema has one required parameter, rule_id, but the description does not mention it at all. Schema description coverage is 0%, so the description fails to compensate. The parameter name is self-explanatory, but no context is added about where to find the rule_id or how it relates to the list.

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 states 'Delete URL black/white list' which is ambiguous—'黑白名单' can mean both blacklist and whitelist, yet the tool name is specifically 'delete_url_blacklist'. It does not distinguish from sibling tools like delete_domain_blacklist or explain whether it affects both lists. The verb and resource are present but the scope is unclear and potentially misleading.

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. There is no mention of how it relates to list_url_blacklist or add_url_blacklist, nor any exclusions or prerequisites. The description simply states the action without any contextual direction.

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