create_tag

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

The annotations already indicate a non-readonly, non-idempotent, non-destructive open-world operation, and the description does not contradict them. However, it adds no extra behavioral context such as duplicate-name behavior, permission requirements, or side effects, so it contributes little beyond the annotations.

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 a single short Chinese sentence with no redundancy or filler. It is appropriately concise for a simple create operation and easy to parse quickly.

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 one-parameter create operation with an output schema and annotations available, the core invocation information is present. However, the definition lacks guidance on when to choose it over related tag tools and does not describe important edge behavior, leaving it minimally adequate rather than thorough.

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%, so the description would need to explain the 'name' parameter, but it does not. The tool description implies that 'name' is the tag's name, yet no constraints, uniqueness expectations, or format details are provided.

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 a specific verb and resource: '创建用户标签' (create user tag). This clearly separates it from tag-management siblings like list_tags, update_tag, and delete_tag, and even from tag_users, which applies tags rather than creating them.

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 given about when to use this tool versus alternatives such as tag_users or update_tag. The description simply states the action, leaving the agent to infer usage from the tool name alone.

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