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

With no annotations, the description carries the full burden. It usefully enumerates the returned fields (status, hotel, confirmation code format, dates, price, free-cancellation flag), which is real value. However, it says nothing about authentication requirements for the required token or any rate-limit/error behavior, so transparency is partial.

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?

One front-loaded sentence that names the operation first and then lists the fields delivered. No filler, though the field enumeration is dense and could be marginally tighter.

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?

By describing the returned fields, the description partially compensates for the absence of an output schema. But with no annotations and an undocumented required token, an agent still lacks auth and invocation context needed to call it confidently.

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% and the single required parameter 'token' is never mentioned in the description. An agent gets no explanation of what the token is, where to obtain it, or its format, so the description fails to compensate for the coverage gap.

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+resource: 'Lista todas as reservas do hospede (passadas e futuras)', leaving no doubt about the operation or scope. It does not explicitly differentiate from potentially overlapping siblings like get_order_status, which keeps it from a 5.

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 explicit when-to-use guidance, no exclusions, and no mention of alternatives among siblings such as get_order_status or cancel_booking. Usage is only inferable from the resource name.

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