User Add

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

With no annotations provided, the description carries the full behavioral burden, yet it only adds the bare tag '写操作' to signal mutation. It says nothing about required permissions, what happens if the username already exists, whether password/email are mandatory, or how the session profile parameter affects execution.

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?

A single short sentence with no wasted words, front-loading the verb and resource. It is arguably too terse for a 10-parameter mutation tool, but as a conciseness measure it is efficient.

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 mutation tool with zero annotations, 10 parameters, and no output-schema explanation needed, the description is far too thin: it omits auth prerequisites, error/duplicate behavior, and any interaction with the session profile parameter, which the schema alone does not clarify.

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%, so all 10 parameters including host, port, scheme, profile, and password are already documented in the schema. The description adds no parameter-level meaning beyond that, so the baseline of 3 applies.

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 NAS 用户'), so an agent immediately knows this creates a user account rather than modifying or deleting one. However, it offers no explicit differentiation from the many adjacent user-management siblings (user_mod, user_del, user_group_add), relying on the tool name alone to disambiguate.

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 guidance on when to use this tool versus alternatives, nor any prerequisites such as requiring an authenticated admin session (login/submit_auth_code siblings exist). The agent must infer usage context entirely from the name.

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