gumroad_list_sales

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

No annotations are provided, so the description must fully convey behavioral traits. It mentions filtering but omits pagination behavior (though a 'page' parameter exists), rate limits, authentication details beyond requiring an API key, and the nature of the response (e.g., array of sales or paginated results).

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 extremely concise—two sentences with no unnecessary words. The primary action is front-loaded. Every sentence provides information without 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?

Given no output schema, the description should clarify the return format or pagination. It mentions filters and implies a list, but lacks details on pagination (page parameter) and response structure. It is adequate but incomplete.

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 input schema has 100% description coverage for all 6 parameters, achieving a baseline of 3. The description adds minimal value by listing the filter types (product, email, date range), but this does not significantly enhance understanding 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?

The description clearly states the tool lists sales from a Gumroad account and can be filtered by product, email, or date range. The verb 'list' and resource 'sales' are specific. However, it does not explicitly differentiate from sibling tools like gumroad_get_sale or gumroad_list_subscribers, but the plural vs singular and filter options provide implicit distinction.

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 provides no guidance on when to use this tool versus alternatives like gumroad_get_sale or gumroad_list_products. It does not mention any prerequisites, exclusions, or context for use.

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