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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description usefully adds what the payload contains (categories, sizes, toppings, cooking instructions), but says nothing about freshness, store-specific availability, or result size beyond that.

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 sentence with the resource front-loaded and the enumerated contents following. It is slightly dense but every clause describes actual catalog contents, so nothing is wasted.

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 needn't be explained, and the one required parameter is fully specified. For a read-only, single-parameter catalog lookup the description is essentially complete; only an explicit sibling contrast is missing.

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% and the single store_id parameter is fully documented in the schema, including its provenance (/dominos/store-locator). The description's 'One Domino's store's' phrasing reinforces that the catalog is store-scoped but adds no format or syntax detail beyond the schema.

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 resource and scope: a single store's build-your-own customization catalog, enumerated as sizes, crust/flavor styles, toppings, sides, and cooking instructions. This clearly separates it from dominos_menu and dominos_nutrition, though it never names those siblings to reinforce the contrast.

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 'build-your-own' framing implies this is the tool for retrieving customization options when constructing an order, but there is no explicit when-to-use statement, no exclusion of alternatives (e.g. dominos_menu), and no note about prerequisites beyond the store_id.

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