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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it delivers: it states output is normalized, the storefront URL is fixed server-side, and — most valuably — that valid empty result pages return 200 with an empty products array, which prevents an agent from misinterpreting an empty response as an error. It doesn't cover pagination metadata or rate limits, but for a simple catalog list this is solid behavioral context.

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?

Three sentences, all essential and non-redundant. The purpose is front-loaded in the first sentence, the data source context comes second, and the behavioral caveat closes. No filler, no repetition of schema content.

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?

This is a simple paginated list tool with two optional, fully-documented parameters; the description covers purpose, source, normalization, the fixed-URL constraint, and the key pagination edge case. The main gap is that with no output schema, 'normalized products' leaves the return shape unspecified — an agent doesn't know what fields a product object contains until it makes a call.

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 coverage is 100% — page (1-based, defaults to 1) and limit (defaults to 50, up to 250) are both fully documented in the schema, so the description needs to add little. It does add one meaningful piece: the empty-array-on-valid-page behavior clarifies how the page parameter's results should be interpreted. This matches the baseline 3 for fully-schema-covered parameters.

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?

'List Allbirds products' is a specific verb+resource that clearly states the operation. The added detail — 'public product catalog' with a fixed server-side URL — helps distinguish it from collection-scoped or store-scoped siblings like allbirds_collection_products and allbirds_store. However, it never explicitly names a sibling alternative, so the differentiation is implicit rather than explicit.

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 implies when this tool is useful (browsing the entire Allbirds product catalog) and the fixed-server-side-URL note hints that no storefront selection is needed, but it gives no explicit when-to-use guidance or exclusions versus the many related allbirds_* siblings. The empty-page-returns-200 behavior adds useful interpretation context, but nothing tells an agent to prefer this over allbirds_collection_products for a collection-scoped query.

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