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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds useful behavioral detail beyond annotations: plain brand names are resolved through Ozon search, ads are filtered from results, and filters{} are supported. This gives the agent a clearer model of what happens during invocation.

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 three short sentences with no filler. Key facts are front-loaded: what the tool is, what inputs it accepts, and what output behavior to expect. Every sentence earns its place.

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 and eight parameters including nested filters, the description is somewhat thin. It tells the agent what is returned ('brand products') but not the shape, default limits, or how compact/rich modes affect the response. The brand input resolution is well covered, but the overall calling context is not fully complete for a tool of this complexity.

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 50%, and the description compensates only partially. It adds meaningful semantics for the brand parameter by showing accepted formats (name, slug-id, URL) and the search-resolution behavior. It also mentions filters{}, but it does not clarify sort, limit, priceMin, priceMax, or rich/compact beyond what the schema already states, leaving some parameters under-explained.

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 uses a specific verb-resource pairing: browse an official brand storefront on Ozon. It clearly identifies the target resource as brand-specific, distinguishing it from category browsing, seller catalogs, and general search. The accepted input forms and the note about ads being filtered out add further specificity.

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 description provides clear context for when to use this tool: when the agent needs products from an official Ozon brand storefront. It explains the accepted brand identifiers and that plain names are resolved via Ozon search, which gives practical invocation guidance. It does not explicitly exclude sibling tools, but the brand-storefront framing sufficiently implies the appropriate scope.

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