Payroll Readiness Checklist

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

The description reveals the tool is a read-only, idempotent operation (consistent with annotations) and adds context about the status values and the missingFields array. No contradictions.

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 concise, with two front-loaded English sentences plus a Spanish translation. The status list is structured and every sentence adds value.

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 the single parameter with full schema coverage, annotations, and straightforward purpose, the description is complete. It tells what it returns, when to use it, and the status schema.

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 only parameter 'month' is fully described in the schema (pattern). The description adds the format example and usage context but does not provide additional parameter-specific semantics beyond what the schema offers.

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 employees for a month with payroll readiness status. It distinguishes itself from siblings by specifying use before payroll_export, and explains status values in detail.

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?

Explicit guidance to use before payroll_export to identify gaps, along with month format specification. This tells the agent when and in what order to use the tool relative to siblings.

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