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 does add useful context: the booking is real, payment occurs at the hotel, and the response includes nights and total. However, it does not disclose potential side effects like duplicate bookings, cancellations, or whether confirmation/availability checking is required.

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 compact, front-loaded, and bilingual without unnecessary wording. Both sentences contribute to understanding the action, inputs, output, and payment behavior.

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 there is no output schema, the description usefully explains what is returned and that payment happens at the hotel. The schema covers the rest of the parameter detail. It is not perfect because it omits potential repeat-call implications and cancellation/confirmation behavior, but it is reasonably complete for a booking tool.

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?

The input schema already describes all parameters at 100% coverage, so the baseline is 3. The description adds little beyond repeating room name, dates, and guest count; it mentions that the room name comes from ver_negocio, but the schema already states that. No meaningful extra parameter semantics 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 uses a specific action ('Reserva/Books a REAL hotel room as a guest') and clearly identifies the resource, inputs, and return behavior. It also distinguishes this from sibling tools like reservar_cita and pedir_comida by explicitly saying hotel room booking.

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?

The description indicates this is for hotel room bookings and mentions that the room name comes from ver_negocio, giving the agent the correct source context. It does not explicitly state when not to use it or name alternatives, but the hotel-room wording and sibling names make the use case fairly clear.

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