Get Price Stats

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 accurately describes the output statistics but does not mention behavioral traits such as data freshness, performance, or error handling. As a simple read operation, this is adequate but not detailed.

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 concise, front-loaded with the verb 'Returns', and contains no extraneous information. Every word adds value.

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 low complexity and lack of output schema, the description adequately lists the six statistics it returns. It clarifies the scope as 'across all products'. Minor improvement: could explicitly state that no filtering is supported.

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 tool has no parameters, so the schema coverage is 100%. Per guidelines, a baseline of 4 applies. The description adds meaning by specifying what the output contains, which the schema does not address.

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 explicitly states that the tool returns count, min, max, average, median, and total price across all products. It clearly identifies the resource (price stats) and the verb (returns), distinguishing it from sibling tools like getProducts or getCategoryStats.

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 description provides no guidance on when to use this tool versus alternatives. With many sibling tools offering specific price queries (e.g., getCheapestProduct, getMostExpensiveProduct), the tool would benefit from stating that it provides aggregate statistics rather than individual product data.

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