snowflake_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 burden of behavioral disclosure. It states it creates a user but does not disclose side effects (e.g., whether existing users are modified, permission requirements), idempotency behavior (the schema shows if_not_exists defaults to true, but this is not mentioned), or what happens if the user already exists. It also omits password requirements and whether a password is optional or needed for authentication setup. This is a significant gap for a mutation operation.

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 sentence that is front-loaded with the action and resource. It is concise and wastes no words. However, its brevity is a symptom of under-specification rather than efficient summarization, but the dimension measures conciseness and structure, and it scores well on those grounds.

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 create operation with no annotations and an output schema (which is not visible to the agent), the description is incomplete. It does not mention prerequisites (e.g., the role and warehouse must exist), default behavior (if_not_exists), or error conditions. It also does not indicate what the returned output represents. Given the complexity of user creation (passwords, roles, warehouses), the description is insufficient for reliable 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?

With 0% schema description coverage, the description must explain parameters, but it only mentions 'default role and warehouse' by name, which maps to default_role and default_warehouse. It does not explain comment, password, or if_not_exists semantics. For a create operation, password and if_not_exists are critical for correct invocation. The description adds almost no value beyond the parameter names already present in the schema.

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 clearly states the verb 'Create' and the resource 'a new Snowflake user', and mentions the key attributes default role and warehouse. This distinguishes it from list/describe user tools and other create tools (e.g., create_database) by resource type. However, it does not differentiate from create_role or other create operations that also involve users indirectly, nor does it mention the 'if_not_exists' default behavior, but the core purpose is unambiguous.

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. It does not mention that this is for creating a user specifically, nor does it contrast with list_users, describe_user, or create_role. The description implies usage only by stating what it does, but it provides no context for selection or exclusions. An agent could mistake it for a general user management tool or overlook prerequisite checks (e.g., role/warehouse must exist).

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