db_create_user

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Create a database user' and lists arguments; it does not disclose permissions required, side effects, whether confirmation gates the action, or any failure modes. The claim that 'confirm: Required' also conflicts with the schema, where confirm is not required and has a default of false.

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 very short, but this is under-specification rather than efficient conciseness. It lacks necessary parameter details and provides no actionable context. The argument list is minimal and one entry is inaccurate relative to the schema.

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 creation tool with no annotations, vague parameters, and no usage guidance, the description is incomplete. An agent cannot determine what a valid payload looks like, what 'confirm' controls, or how this differs from db_create_with_user. Even with an output schema present, the input semantics remain critically under-defined.

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 must compensate, but it barely does. 'payload: User body' is vague and unhelpful, especially since payload is an open-ended object with additionalProperties true. 'confirm: Required' is misleading because the schema marks only payload as required and gives confirm a default. No parameter structure, meaning, or allowed values 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: 'Create a database user.' This distinguishes it from related siblings like db_create (create a database) and db_delete_user (delete a user), though it does not explicitly contrast 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 db_create_with_user, db_create, or db_user_get. The 'confirm' argument is mentioned but not explained as a usage condition, and no prerequisites or context are described.

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