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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the date-bound and single-property scoping context, but says nothing about rate limits, data freshness, currency behavior, or locality nuances that would be useful for a live-rate lookup.

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?

A single tight sentence with the key scope constraints front-loaded. Zero waste and easy to parse.

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?

An output schema exists, so return values need not be explained, but a 6-parameter tool with 0% schema coverage and no required-parameter documentation demands more than one sentence. The description leaves most parameter meaning and usage context undocumented.

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 6 parameters and 0% schema description coverage, the description carries the full burden. It only hints at check_in/check_out ('date-bound') and property_id ('one property'), leaving adults, locale, and currency entirely unexplained in both description and schema. Partial compensation at best.

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 states a specific verb (Get) and resource (Hotels.com rates) with clear scope qualifiers: 'date-bound' and 'for one property'. This distinguishes it from search-style siblings, but it does not name any sibling (e.g., hotels_search or hotels_property) to route the agent explicitly.

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 guidance on when to use this tool versus alternatives like hotels_search, hotels_property, or hotels_offers. The phrase 'for one property' weakly implies a property_id prerequisite, but no when/when-not conditions or alternatives are stated.

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