list_documents()
Reasoning 
The task is a retrieval task for contribution_cap. But we need a payroll month — the task says "Retrieve the case inputs with list_documents and read_document." So there must be a document with payroll month. Let me list documents.

R8: retrieval needs a month covered by a reference row. The answer fields: decision, field, value, clauses. Value is decimal string.

Let me list documents first.

lookup_reference(reference="first-half")
Reasoning 
Payroll month 2026-05. Which half? May is in the first half (Jan–Jun). Let me lookup reference first-half. The case schedule may be supplied; use lookup_reference.

  "clauses": ["R1", "R3"],
  "explanation": "Payroll month 2026-05 falls in the first-half reference row, whose contribution cap is 3500.00."
}
Reasoning 
First-half covers 2026-01 through 2026-06, so 2026-05 is covered. contribution_cap = 3500.00.

Return JSON: decision "retrieve", field "contribution_cap", value "3500.00", clauses ["R1","R3"]. Per R8: cite the selecting rule R1 and the source rule (R3). Explanation optional.

Reasoning 
The task is a retrieval task: contribution_cap. But I need to determine the payroll month from the case inputs. Let me list documents and read them.

Reasoning 
The task says "Retrieve contribution_cap from the supplied rulebook." But retrieval tasks need a payroll month. The instruction says "Retrieve the case inputs with list_documents and read_document." So there must be a case document with payroll_month and field. Let me look.

read_document(document_id="84df35bacd23f57c-payroll")
Reasoning 
Note: months lists "2026-01", "2026-06" — probably meaning range from 2026-01 to 2026-06. Similarly second half 2026-07 to 2026-12.

Read the payroll document.

{
  "decision": "retrieve",
  "field": "contribution_cap",
  "value": "3500.00",
  "clauses": ["R1", "R3"]
}
Reasoning 
Retrieve contribution_cap for 2026-05 → first-half row, cap = 3500.00. R8: cite R1 and R3 (source rule for contribution_cap is R3, selecting rule R1).

Wait, contribution_cap is under R3 (contribution rate multiplied by smaller of gross pay and cap). R8 says contribution_rate and contribution_cap (R1 and R3). So clauses: ["R1", "R3"].

No calculate needed.
