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

With no annotations provided, the description carries the behavioral burden. It does disclose that the operation is a list (read-style) and that results are paginated, which is useful. It does not cover pagination mechanics, response structure, or access requirements, but the core behavior is reasonably clear.

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?

The description is one short sentence with no filler. The key action, resource, output fields, and pagination note are front-loaded and easy to parse.

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?

For a simple optional-parameter list tool, the description covers the essential what and output fields. However, there is no output schema and no annotation coverage, so the description leaves gaps around pagination semantics (page size, page indexing, response format) that an agent would need for robust invocation.

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?

The schema gives no description for the single optional 'page' parameter, and schema description coverage is 0%. The description's mention of 'paginated' adds context that page is likely a page number, but it does not specify indexing, page size, defaults, or how pagination metadata is returned.

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 uses a specific verb ('List') and a specific resource ('brand codes/names known to the catalog'), which clearly distinguishes it from sibling tools like list_shops and list_categories. It also adds a useful scope qualifier ('known to the catalog').

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 to use the tool: whenever brand codes/names from the catalog are needed. However, it does not explicitly state when not to use it or mention alternatives, so the guidance is inferred rather than explicit.

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