What problem does it solve? Building ERP interfaces requires repetitive UI patterns: multi-step forms with per-step validation, print-ready documents like invoices, and audit history timelines. This Skill provides ready-to-use React component implementations for all three, eliminating the need to write them from scratch. ## Core Features & Use Cases - StepWizard: Multi-step form wizard with per-step Zod schema validation, react-hook-form integration, progress indicator with checkmarks, and back/next navigation with final submit. - PrintLayout: Printable document wrapper using @media print CSS that hides UI chrome, sets A4 page dimensions, prevents table page-breaks, and includes a complete invoice template example. - AuditTrail: Timeline component fetching audit log entries via TanStack Query, showing user, timestamp, and old-to-new value diffs with visual strikethrough highlighting. - Use Case: Build an ERP invoice creation flow where users fill a 3-step validated wizard, submit the invoice, view it in a print-ready layout, and inspect its modification history in a timeline. ## Quick Start Use the ui-step-wizard skill to create a multi-step invoice form with Zod validation, a printable invoice layout, and an audit trail timeline.
