list_gross_pay_items

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

With no annotations, the description must disclose behavioral traits beyond the obvious 'list' action. It fails to mention pagination behavior (despite page/page_size parameters), rate limits, or authentication needs. The description adds no value beyond the verb.

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 short sentence with no extraneous words. However, it is too brief to be informative; conciseness should not sacrifice completeness. It earns a middle score for being brief but lacking depth.

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 4 parameters, no annotations, and the presence of an output schema, the description should at least mention that it returns items for a specific payroll and supports optional employee filtering and pagination. It does none of this, leaving the agent underinformed.

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%, yet the tool description provides zero explanation of any parameter. It does not clarify that payroll_id is required, that employee_id is optional for filtering, or that page and page_size control pagination. The parameter names are self-explanatory but the description should add context.

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 'gross pay line items for a payroll run,' specifying the verb (list), resource (gross pay line items), and context (payroll run). While it doesn't explicitly differentiate from sibling tools, the resource name is distinct.

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?

No guidance is provided on when to use this tool versus alternatives like list_payrolls or list_employee_payrolls. There are no prerequisites, exclusions, or context for invocation.

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