create_user

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: no permission requirements, no uniqueness behavior if 'name' already exists, no note on irreversibility, and no indication that 'password' is a sensitive credential field. For a mutating tool this is a serious omission.

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 four-character phrase — not wasteful in the sense of padding, but under-specified rather than concise. There is no front-loaded structure because there is essentially no content to structure.

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 mutating tool with no annotations and no output schema, the description should at minimum cover permissions, failure modes, or credential handling. The schema does document all three parameters, which prevents this from being a bottom score, but the behavioral gap remains significant.

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 100%, with name, tags (including an example values hint), and password each documented in the schema itself. The description adds nothing beyond the schema, so the baseline of 3 applies for adequately documented parameters.

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 '创建用户' is a direct restatement of the tool name create_user — it names the verb and resource but adds no scope, constraints, or distinguishing detail. It does not differentiate this tool from any sibling in a 20-tool set that includes delete_user, list_users, create_queue, etc.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as list_users or delete_user. The implied usage (call it when a new user is needed) is inferable only from the name, not from the description text.

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