What is near a hotel: restaurants, landmarks, transit stations, distances.
| Name | Required | Description | Default |
|---|---|---|---|
| query | No | Hotel name + city | |
| check_in | No | Check-in YYYY-MM-DD | |
| check_out | No | Check-out YYYY-MM-DD |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only mentions the content of results (categories and distances) but does not disclose side effects, data freshness, expected query format beyond the schema, or whether the check-in/out dates affect results. This is insufficient for a tool with no annotation safety hints.
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 extremely short and front-loaded, but it is a noun phrase rather than a sentence, which makes it feel under-specified. While it is concise, it lacks the instructional structure expected of a tool description, so it does not score higher.
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?
Given the tool has no output schema and no annotations, the description is incomplete. It does not explain return format, how to invoke it, or when to use it. The description is too minimal to fully guide an agent in selecting and using the tool correctly.
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 parameters are well-documented in the schema itself. The description adds a slight semantic hint by connecting the parameters to nearby points of interest and distances, but it does not significantly deepen understanding beyond what the schema already provides.
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 what the tool provides ('restaurants, landmarks, transit stations, distances') but lacks an imperative verb like 'list' or 'find'. It clearly relates to a hotel but does not explicitly differentiate from sibling tools like area_guide or hotel_details, making its purpose somewhat vague.
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 guidance on when to use this tool versus alternatives. No context is given for scenarios where this would be preferred over area_guide or hotel_details, nor any exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool addresses a distinct aspect of hotel research: neighborhoods, cheapest options, server health, hotel details, price trends, general search, nearby attractions, and cross-site price comparison. There is no functional overlap between tools.
Tools follow a consistent snake_case convention with descriptive names. Most are noun_noun or adjective_noun patterns (area_guide, hotel_details), with only price_compare using a verb form. The pattern is clear and predictable, though not perfectly uniform.
Eight tools cover the full spectrum of hotel information retrieval without being excessive or sparse. Each tool serves a specific, necessary function for travelers researching accommodations.
The tool set provides end-to-end coverage for hotel research: searching, filtering by price, comparing across booking sites, viewing price calendars, checking nearby places, and getting detailed reviews. There are no obvious gaps for the intended information-only use case.
