gumroad_get_product

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. It does disclose that the result includes variants and is a full product representation, but it omits other behavioral context such as authentication requirements, failure modes, or whether it is a read-only operation.

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 brief and front-loaded with the core meaning. The second sentence, 'Operation id: getProduct', adds marginal value and is somewhat redundant with the tool name, but it does not create significant clutter.

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?

The tool is simple with one parameter and no output schema, and the description states the essential return content ('full' product with variants). However, it does not explain where product_id comes from, how it relates to list_products, or what fields the full product includes, leaving meaningful gaps for an agent.

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 description coverage is 0%, and the description adds no direct meaning for the product_id parameter beyond the parameter name itself. It only implies via context that product_id identifies the product, so the description does not compensate for the schema gap.

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 identifies the resource ('One product'), the scope ('in full'), and the key differentiator ('including its variants'). This distinguishes it from plural or summary siblings like gumroad_list_products and gumroad_get_sales.

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 phrase 'One product' implicitly signals use when a single product is needed rather than a list, but it does not explicitly name alternatives or give conditions for when not to use this tool. The guidance is implied rather than stated.

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