A3.6/5.0
Behavior4/5

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

With no annotations provided, the description carries the full behavioral transparency burden. It adds valuable non-obvious details: products are 'normalized', the catalog is public, the storefront URL is fixed server-side, and valid empty result pages return 200 with an empty products array. These go beyond what the schema reveals, even though auth/rate-limit details are not discussed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four short sentences, each contributing distinct information: the core action, data source and normalization, the server-side fixed URL, and the empty-page behavior. There is no filler, redundancy, or excessive detail, and the primary purpose is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple paginated list tool with no required parameters and a fully documented schema, the description is largely complete. It states the return shape (normalized products array), the source, the pagination edge case, and the server-side constraint. It does not enumerate product fields or error statuses, but those are minor gaps given the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline of 3 applies. Both page and limit are already fully documented in the input schema. The description adds only generic allusions to 'result pages' and 'products array', providing no additional parameter-level meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific action and resource: 'List Oh Polly products.' It further clarifies scope with 'Returns normalized products from Oh Polly's public product catalog.' However, it does not explicitly differentiate itself from closely related siblings like ohpolly_collection_products or ohpolly_product, leaving some ambiguity for the agent about which tool to prefer.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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. It never mentions ohpolly_collection_products, ohpolly_product, ohpolly_collections, or other product catalog tools, nor does it state the conditions under which an agent should choose this list-all-catalog endpoint. The only contextual notes concern the fixed URL and empty-page behavior, not selection criteria.

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