create_product

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

No annotations are provided, so the description carries full responsibility for disclosing behavioral traits. It discloses the RUBLES-to-kopecks conversion, which is useful, but it does not mention return values, error behavior, required permissions, or other side effects. This is a significant gap for a mutating tool.

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 extremely concise: two short sentences with no filler. It front-loads the core purpose and includes the essential currency caveat. Every word 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?

The description is adequate for a simple create tool with a well-specified schema. It lacks information about the return value or failure modes, which is notable given there is no output schema and no annotations. However, it is not completely insufficient because the schema covers all parameters and the purpose is clear.

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 schema has 100% description coverage for all 11 parameters, so the baseline is 3. The top-level description adds a general note about prices being in RUBLES, which is slightly redundant for buy_price_rubles and sale_price_rubles but adds context for min_price_rubles and the overall intent.

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 states the tool's purpose: 'Create a new product.' The verb 'create' and resource 'product' are specific, and this distinguishes it from sibling read tools like search_products and get_product, as well as other create tools for different entities.

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 provided on when to use this tool versus alternatives, or any prerequisites. The description only states what it does, not when to choose it over other tools like create_service or update_prices. There are no exclusions or contextual hints.

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