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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and reach profile is covered. The description adds the concrete, useful constraint that results are pinned to https://www.ohpolly.com, but says nothing about rate limits, auth, or failure behavior when a handle 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 short sentence with the operation and scope front-loaded; every clause carries information and there is no filler.

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?

An output schema exists so return values need not be described, and annotations cover the safety profile, leaving little for the description to carry. It is nearly complete, missing only guidance on where a valid handle comes from and how it differs from the list/search siblings.

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 100% and the single handle parameter is fully documented in the schema as 'Product handle (URL slug)'. The description's 'by handle' phrasing adds no syntax or sourcing detail beyond that, so the baseline 3 applies.

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?

States a specific verb and resource ('product detail') and qualifies the lookup key ('by handle'), plus pins the source store to ohpolly.com. It does not explicitly contrast with siblings like ohpolly_products or ohpolly_collection_products, so differentiation relies on inference from the naming pattern.

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 gives no when-to-use guidance, no alternatives, and no prerequisites beyond the implied need for a handle. The narrow 'by handle' phrasing hints at a required lookup key, but no condition selecting this tool over ohpolly_products is stated.

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