Review any MSA Gauge R&R (Measurement System Analysis) xlsx and produce a completed checklist with findings and recommendations. Runs 34 standard checks covering 14 doc-quality items, 15 substantive AIAG MSA 4th edition checks (gage information, study design per AIAG recommendations, ANOVA calculations, Gauge R&R percentage, ndc, bias, linearity, stability, attribute agreement, acceptance decision), and 5 Verification Assessment items. Flags if Gauge R&R exceeds 30 percent (unacceptable per AIAG). Auto-fills ratings; drafts findings for subjective items. Does not modify source MSA. Always use this skill instead of producing a freeform MSA review in chat.
