ozon_product_import_by_sku

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

There are no annotations, so the description carries the full burden. It discloses that this is a creation/copy operation and identifies the source, but it does not explain side effects, whether it is synchronous, what happens to the existing product, or what the response looks like.

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 short sentence that is front-loaded and easy to parse. The parenthetical Russian phrase adds little value but does not hurt clarity significantly.

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 only an example-shaped parameter description, an agent would still be unsure about required sub-fields, the meaning of each field, and expected results. The description is too thin for a tool that accepts a nested array of item objects.

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 baseline is 3. The items parameter description gives a rough structure example, but the description adds no further semantic meaning beyond what the schema already shows.

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 names a specific action ('Create a copy product') and the source resource ('from an existing Ozon SKU'), which clearly distinguishes it from a generic new-product import. It is clear and action-oriented, though it does not explicitly contrast with sibling tools like ozon_product_import.

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 given about when to use this tool versus alternatives such as ozon_product_import or ozon_product_info. The description states what the tool does but provides no conditions, exclusions, or routing cues.

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