Crear carpeta

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

Annotations already declare write operation (readOnlyHint=false), non-destructive, non-idempotent, and closed-world. The description adds a useful constraint ('No sobrescribe rutas existentes'), but does not explain what happens if the path exists (error? duplicate?), nor mentions the confirmar or aprobacion_id parameters or any confirmation requirements.

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?

Two short sentences with zero waste. The purpose is front-loaded, followed by a key behavioral constraint. Perfectly sized for a simple tool.

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?

With three parameters and no schema descriptions, the description should explain parameter semantics and the approval/confirmation workflow. It omits all of that, and there is no output schema to clarify returns. Incomplete for a tool that likely requires an approval ID.

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. It does not mention any of the three parameters (ruta, confirmar, aprobacion_id), their formats, or their purposes. The only hint is 'dentro del espacio autorizado', which is vague and insufficient.

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?

States a specific verb and resource ('Crea una carpeta nueva') and adds scope ('dentro del espacio autorizado'). Clear what the tool does, but does not explicitly differentiate from siblings like eliminar_carpeta or mover_elemento beyond the obvious name.

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 on when to use this tool versus alternatives. Does not mention prerequisites, when-not to use, or any sibling tool. Only states what it does.

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