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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds only the source domain; it says nothing about result ordering, whether the catalog is complete, or how pagination behaves beyond what the schema states.

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?

One short, front-loaded sentence with zero filler. It is efficient, though it is arguably too terse for a listing tool rather than trimming genuine redundancy.

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?

With an output schema present, return values need not be explained, and parameters are covered. What is missing is the routing context: which sibling to use for collection-scoped or keyword-scoped product retrieval, which is the main decision an agent faces among the many ohpolly_* tools.

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% – page (1-based, default 1) and limit (default 50, max 250) are fully documented in the schema. The description adds no extra meaning, 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?

The description names the resource (Oh Polly storefront products) and pins it to a domain, so the agent knows which store it is. But there is no explicit verb and no differentiation from close siblings like ohpolly_product (single item) or ohpolly_collection_products (collection-scoped), so an agent must infer that this is an unfiltered store-wide listing.

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?

There is no when-to-use guidance: nothing says to prefer this over ohpolly_collection_products when you need a specific collection, nor over ohpolly_search_suggest for discovery. No prerequisites, no mention of when pagination matters.

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