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

No annotations are provided, so the description carries the full burden. It does not disclose important behaviors like uniqueness of product ID, idempotency, duplicates, or the requirement that the store_id reference an existing store. The single sentence adds no behavioral detail beyond the action itself.

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 sentence that is front-loaded with the verb and resource, with no unnecessary words or repetition. It is concise and to the point.

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?

Even though the schema covers parameters, the description is contextually incomplete for a 10-parameter create operation. It omits prerequisites (e.g., store existence), uniqueness or idempotency constraints, and any error or response expectations. The agent lacks critical context to use the tool safely and correctly.

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 input schema covers 100% of the 10 parameters with individual descriptions, so the baseline is 3. The description itself adds no additional parameter semantics, but the schema already provides adequate field-level documentation.

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 'Add a new product to a store' uses a specific verb (Add) with a clear resource (product) and scope (store), distinguishing it from sibling tools like products_update, products_delete, and stores_add. It directly states the action and target.

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, nor any mention of prerequisites such as the store needing to exist. The description only states the action without context on eligibility or exclusion conditions.

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