ozon_product_attributes_update

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 only states that product characteristics are updated, but does not disclose whether the update merges or replaces existing attributes, whether attribute IDs must already exist, what side effects occur, or how success/failure is reported. For a mutation tool, this is a significant gap.

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 states the core action efficiently. The Russian parenthetical is redundant but brief and likely aids non-English users; it does not materially harm conciseness.

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?

For a relatively simple one-parameter tool, the description and schema together cover the what and the parameter shape. However, there is no mention of typical workflows like fetching valid attribute IDs from a category, no return value guidance, and no behavioral details, leaving an agent with some uncertainty about preconditions and outcomes.

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%, as the items parameter includes a compact structure example ('[{offer_id, attributes: [{id, values}]}]'), so the schema already conveys the expected shape. The description adds no additional meaning about parameter formats, types, or constraints, placing it at the baseline for high coverage.

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 ('Update') with a clear resource ('product characteristics') and adds a meaningful distinguishing note ('without a full card re-upload'), separating it from full-import tools. It does not explicitly name or differentiate against the sibling ozon_product_attributes, so it falls just short of full sibling-level clarity.

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 phrase 'without a full card re-upload' implies this tool is for partial attribute updates rather than full product re-imports, giving some usage context. However, there is no explicit guidance about when to prefer this over related tools like ozon_product_attributes or ozon_product_description, and no stated exclusions or prerequisites.

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