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 externally. The description adds only the scope of suggestions (destination/property) and nothing about response shape, rate limits, or the fact that results are partial prefixes. It adds limited value beyond the annotations, so a 3 is appropriate.

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 efficient sentence with the resource and purpose front-loaded. Nothing is wasted, though it is short enough that structure is trivial.

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. For a one-parameter autocomplete this is adequate, but the description does not clarify input expectations or how results relate to the full search flow, leaving minor gaps.

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 schema gives no meaning for 'q'. The description implies q is free-text pointed at destinations or properties, which is a small but useful addition; however it does not specify the expected input format (prefix string, city name, hotel name). Baseline is limited because the single parameter is undocumented everywhere.

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 ('Get') and resource ('Hotels.com destination or property search-box suggestions'), making the purpose immediately clear. It also scopes the suggestion domain to destination or property. It stops short of naming which sibling (e.g. hotels_search) it complements, so it does not earn 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?

The phrase 'search-box suggestions' implies the intended use (typeahead before a full search), but there is no explicit when-to-use versus when-not, and no alternative tool named. Usage is only implicitly conveyed.

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