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

With no annotations, the description must carry the behavioral load, and it does disclose that results are read live from beaches.com and that the payload contains resort names and booking URLs. It does not cover failure modes, latency, or whether live reads can be incomplete, leaving meaningful gaps for an un-annotated network-backed tool.

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?

Two short sentences with zero filler; the identity and the data-source/return behavior are front-loaded. Every clause carries information.

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?

It covers what the tool is and roughly what comes back, which is the minimum for a three-optional-parameter tool with no output schema. Missing are how destination/best_for interact with the search, what max_results does by default, and whether pricing or availability is included.

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 description adds no parameter information at all. At 67% schema coverage, max_results is undocumented anywhere and best_for's allowed values are only loosely implied, so the description fails to compensate for the gap it should be filling.

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 and resource ("Search Beaches Resorts") and scopes it as the family all-inclusive brand, which implicitly separates it from search_sandals_resorts. It doesn't explicitly name the sibling or clarify the boundary with get_sandals_beaches_deals, so differentiation requires inference.

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 parenthetical "(family all-inclusive)" implies the audience condition for choosing this tool, and the destination values in the schema hint at scope. However there is no explicit when-to-use/when-not guidance and no routing to sibling tools like search_sandals_resorts or get_resort_booking_url.

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