billy_list_products

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that filtering and pagination are optional, but does not disclose defaults (e.g., page size), return format, or any side effects. This minimal information is insufficient for a tool with no structured safety annotations.

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 a single seven-word sentence that is front-loaded and free of redundancy. Every word earns its place, making it highly efficient.

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 list tool with six optional parameters and no output schema, the description is adequate but incomplete. It does not explain the return value structure or provide usage context beyond the bare essentials. The high schema coverage partially compensates, but without annotations, the description could be richer.

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?

Input schema covers 100% of parameters with descriptions, so the baseline is 3. The tool description groups parameters into 'filtering' and 'pagination', but adds no substantive meaning beyond the schema. It is not misleading, just redundant.

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 resource ('products') with mention of optional filtering and pagination. It clearly indicates this is a list operation, distinguishing it from singular get_product and create_product by name, but does not explicitly contrast with those siblings.

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 usage when the goal is to list products with optional filtering/pagination. However, it provides no explicit guidance on when to prefer this over billy_get_product or billy_create_product, nor any exclusions or alternative recommendations.

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