createUser

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

The description only implies creation (a write operation) but provides no details about required permissions, side effects, or what response to expect. Without annotations, the burden is higher, yet the description adds no behavioral context.

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 extremely short (two words) but is underspecified rather than concise. It lacks essential information, making it ineffective for an AI agent.

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?

Given the tool's complexity (nested parameters, many fields) and the absence of an output schema, the description is completely inadequate. It fails to cover required information such as response format, error conditions, or usage constraints.

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 and no parameter-level descriptions in the tool description, the two-word description adds zero value beyond the schema itself. Users must infer parameter meanings solely from names and structure.

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 'Create user' is a tautology of the tool name 'createUser'. It merely restates the verb and resource without adding any specificity or distinguishing it from sibling tools like createGroup, createIssue, 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?

No guidance is provided on when to use this tool versus alternatives such as updateUser or getUsers. There are no prerequisites, context, or exclusions mentioned.

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