Examples

Prompt

We are acquiring 100% shares of TechCo Ltd.
Here is the data room summary: [paste document list]
Deal size: $5M. Materiality: $50K.
Key concern: their main product relies on a patent expiring soon.
Conduct a legal due diligence and flag deal-breakers.

Quality Criteria

  • Every finding is tied to a specific evidence source (log, test, metric)
  • Pass/fail criteria are binary and measurable — no subjective judgments
  • Severity levels are assigned with clear thresholds
  • Remediation steps are provided for all critical and high findings

Verification (4C)

CheckQuestion
CorrectnessAre all pass/fail criteria applied against the correct standard or rule?
CompletenessWere all required dimensions or checklist items evaluated?
Context-fitDoes the verification scope match the actual risk level of the deliverable?
ConsequenceIf this passed verification but had a hidden flaw, what is the worst-case impact?

Edge Cases

  • Incomplete data for full assessment — Document which checks were limited and flag for re-verification when data becomes available.
  • Ambiguous pass/fail criteria — Request clarification from the standard owner before scoring. Mark as 'Needs Review'.
  • Multiple overlapping standards — Identify the governing standard and note where others diverge.

Changelog

  • v1.0.0 — Initial release
