About

QA gate that validates analysis outputs before they're shared with stakeholders — checking classification accuracy, calculation consistency, confidence band reasonableness, and data quality flags. Use this skill when the user says 'validate the analysis', 'QA check', 'sanity check the numbers', 'verify the results', 'check for errors', 'is this right?', 'review before sharing', or any indication they want a second pair of eyes on the outputs. Also trigger automatically before the business-case-builder produces a final document — savings estimates in a business case that don't add up will destroy credibility. Think of this as the skeptical reviewer who asks the uncomfortable questions before the CFO does.

Use cases: documents, testing, data
