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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the tool is a 'catalog' which implies a read-only list of items, but it does not explicitly describe the return format, whether the list is exhaustive, any pagination behavior, or whether the data is static or dynamic. The minimal noun phrase lacks the verb structure that would clarify what the tool actually does (e.g., 'Returns a catalog of...').

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 concise, consisting of a single short phrase that conveys the essential purpose. There is no unnecessary wording, and it is front-loaded with the key information. While it is terse, conciseness does not penalize lack of detail—other dimensions address completeness. This is an efficient, well-structured description for its intended simplicity.

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 parameters and no output schema, the description is the only provided context. It is minimally viable by stating the domain (pool slides and waterfalls), but it lacks important context such as what information the response contains (e.g., prices, dimensions, availability), whether the catalog is static or dynamically updated, or any special behaviors. It could be improved by explicitly stating that it returns a list of available slides and waterfalls and perhaps noting if there are no filtering options.

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 tool has zero parameters, and the schema is an empty object. With no parameters to explain, the description does not need to provide parameter semantics. The baseline score of 4 is appropriate because there is nothing for the description to add about parameters, and the schema coverage is effectively 100% (vacuously).

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 'Каталог горок и водопадов для бассейнов' clearly identifies the resource (slides and waterfalls for pools) and implies a listing/catalog function. It effectively distinguishes this tool from sibling tools like get_filters and get_furniture by specifying the exact category of pool equipment. However, it relies on the tool name to convey the verb (get), rather than using an explicit verb like 'list' or 'retrieve'.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention any prerequisite conditions, context, or exclusions. Since sibling tools include other catalog-type tools (e.g., get_filters, get_furniture), users are left to infer that this tool is specifically for slides and waterfalls, but the description does not explicitly state the intended use case.

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