Finance Agent Validation Checklist

A compact checklist for inspecting finance-agent assumptions, calculations, scenarios, validation, and audit trail.

Finance Agent Validation Checklist

A finance agent should never answer with only a confident paragraph.

When it touches a model, the review packet matters more than the prose. The checklist below is the minimum I use before treating an agent-run model change as reviewable.

1. Inputs

The agent identifies every assumption it used.

Required evidence:

  • input name;
  • prior value;
  • new value;
  • source or instruction;
  • unit;
  • period;
  • whether the input is synthetic, public, or private.

If an assumption appears only inside a formula, the model is already less inspectable.

2. Calculations

The agent shows which calculations were affected.

Required evidence:

  • changed formulas;
  • downstream dependencies;
  • formulas that were intentionally left unchanged;
  • period alignment checks;
  • no hardcoded scenario values inside output cells.

The important question is not whether the final number looks plausible. It is whether the path to the number survived the change.

3. Scenario Isolation

The agent keeps the base case separate from the scenario.

Required evidence:

  • base case preserved;
  • scenario branch named;
  • changed assumptions scoped to the scenario;
  • outputs labeled by case;
  • no accidental overwrite of the original model state.

This is where many agent demos fail quietly.

4. Validation

The agent runs checks before reporting.

Minimum checks:

  • balance or structural checks where relevant;
  • timeline continuity;
  • reasonability tests;
  • guardrail thresholds;
  • sensitivity to the changed assumption;
  • explicit unresolved limitations.

Validation is not a confidence sentence. It is a set of checks a reviewer can inspect.

5. Audit Trail

The agent leaves a human-readable trail.

Required evidence:

  • what changed;
  • why it changed;
  • what recalculated;
  • which checks passed;
  • which checks failed;
  • what the reviewer should inspect next.

The final answer should be the summary of the model state, not a substitute for it.

6. Variance Commentary

The agent proves that budget-vs-actuals commentary uses the right model surface.

Required evidence:

  • account mapping completeness;
  • reporting-period basis;
  • out-of-period entries excluded;
  • budget, actual, and variance by management line;
  • largest unfavorable variance before and after checks;
  • EBITDA or operating-metric reconciliation where relevant.

The budget variance agent review protocol is intentionally small: it catches the class of error where a finance agent writes a plausible explanation from the wrong period or mapping.
