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

No annotations are provided, so the description carries the burden. It usefully conveys that the operation is a read of public data, implying no mutation and likely no authentication. However, it does not disclose error behavior, access restrictions, or what happens if the product does not exist.

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?

A single, well-structured sentence that front-loads the action and resource, then lists returned fields. No filler or repetition.

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 minimal single-parameter read, but it omits the critical relationship to read_free_product and read_paid_product, and does not explain when preview is the appropriate choice. With no annotations or output schema, this leaves an agent uncertain about tool selection and expected behavior.

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 mentions product_id or how to identify the product. While the schema defines length constraints, the semantic meaning of the identifier and its role are left undocumented, which the description should compensate for.

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 states a clear verb ('Read') and a specific resource ('one product's public metadata, summary, version hash, price, and license'), making the core purpose evident. However, it does not distinguish preview_product from the sibling tools read_free_product and read_paid_product, which also appear to read a single product.

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 read_free_product, read_paid_product, list_products, or search_products. The sibling names suggest a meaningful distinction, but the description leaves the selection entirely to inference.

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