read_document(document_id="cc74d2a8fe768d29-payroll")

Reasoning

Read the payroll document.

Tool

{
  "kind": "payroll",
  "record": {"gross_pay": "8261.80", "allowed_deduction": "143.37"}
}

Assistant

  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record omits payroll_month, a required input, so no reference row can be selected. Please supply the payroll month in YYYY-MM format within 2026."
}

Reasoning

No payroll_month. Per R7 order: missing gross_pay first (gross_pay present), then missing payroll_month → clarify MISSING_PAYROLL_MONTH, citing R1 and R7.

  "clauses": ["R1", "R7"]
}

Reasoning

The payroll record has no payroll_month. Per R7, missing payroll_month → clarify MISSING_PAYROLL_MONTH, citing R1 and R7. Check order: 1. Missing gross_pay — gross_pay present ("8261.80"). 2. Missing payroll_month — yes, missing. Return clarify.

But wait — is payroll_month possibly implied? The record only contains gross_pay and allowed_deduction. So MISSING_PAYROLL_MONTH.

Reasoning

Read the payroll document.

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay but no payroll_month, so no reference row can be selected. Please provide the payroll month in YYYY-MM format within 2026."
}

Reasoning

The record has gross_pay and allowed_deduction but no payroll_month. Per R7 order: 1. gross_pay present. 2. payroll_month missing -> clarify MISSING_PAYROLL_MONTH, cite R1 and R7.

Wait, but perhaps the payroll_month is elsewhere? Only one document. The record lacks payroll_month. So clarify with MISSING_PAYROLL_MONTH.
