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

Annotations already establish readOnly, idempotent, and openWorld hints, so the description only needs to add information beyond those. It contributes the important behavioral detail that calls return partial-success results, which is not stated in the annotations and is useful for an agent deciding whether to tolerate per-hotel failures.

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 a single efficient sentence with no filler: it front-loads the action and resource, specifies the batch scope, and closes with the key partial-success behavior. Every clause earns its place.

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 a complete input schema, an output schema, and readOnly/idempotent annotations, the description has comparatively little burden. The only potential gap is that partial-success semantics are named but not explained; however, the output schema can reasonably carry that detail.

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 100%, so the schema already documents all eight parameters, including hotel_ids, dates, occupants, and user_key. The description adds little parameter-level meaning beyond implying that hotel_ids can contain multiple hotels.

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 verb ('Get') with a clear resource ('live room types and rate products') and a defined scope ('multiple hotels'), and it highlights the distinctive partial-success result mode. The batch scope differentiates it from sibling query_room_rates without needing to open the schema.

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 or when-not-to-use guidance, and no sibling alternative is named. The phrase 'for multiple hotels' and the 'batch' title imply the intended use, but the description leaves the contrast with query_room_rates and check_room_availability to inference.

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