ozon_product_certificates

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

With no annotations provided, the description carries the full burden of disclosing behavior, but it only states a domain rule about expired certificates blocking the card. It does not indicate whether the tool performs a read-only lookup, whether it returns statuses or expiration dates, or whether there are any side effects.

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 very short but under-specified rather than appropriately concise. The leading phrase 'Product certificates' is a repeated label rather than a useful instruction, and the additional clause adds context but does not compensate for missing operational details.

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 lack of annotations, no output schema, and a single required parameter, this description is incomplete for safe and correct invocation. An agent cannot determine what data will be returned, whether the operation is read-only, or how this tool differs from the many sibling certificate-related tools.

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 0%, and the description never explains the product_id parameter. While the parameter name is somewhat self-explanatory, the description does not confirm whether the provided product IDs select products whose certificates are returned, leaving the relationship between input and output ambiguous.

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 is essentially a noun phrase that mirrors the tool name: 'Product certificates' adds no operative verb such as 'get', 'list', or 'validate'. The detail about an expired certificate blocking the card gives domain context but does not clarify what action the tool performs on those certificates.

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 guidance on when to use this tool versus sibling certificate tools such as ozon_certificate_list, ozon_certificate_info, or ozon_brand_certificates. No conditions, exclusions, or alternatives are mentioned.

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