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

No annotations are provided, so the description must carry behavioral context. It implies a read-only informational tool and describes the returned content categories, but it does not state freshness, caching, rate limits, or whether all catalog sections are always included.

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 a single front-loaded sentence that efficiently lists the catalog components returned. It is dense but every phrase contributes information, with no obvious filler.

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?

With no output schema, the description adequately explains the return contents: sections, product counts, in-stock counts, collections by several dimensions, brands, service pages, and URLs. It could still specify the exact response structure, but it is sufficiently complete for a zero-parameter catalog overview tool.

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, so there are no parameter semantics to explain; the baseline score of 4 is appropriate. The description does not need to compensate for missing schema parameter details.

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 clearly identifies the resource: catalog structure, including sections with product counts, collections within sections, brands, and service pages with URLs. It is specific enough to distinguish this from product search or catalog change tools, though it does not explicitly name or contrast sibling tools.

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 such as usilitel_catalog_status, usilitel_products_search, or usilitel_content_search. Usage is only implied by the noun phrase 'Структура каталога'.

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