What problem does it solve? Making design or layout changes directly on a live production site is risky and hard to review. This Skill provides a disciplined workflow for testing UI changes on a sandbox or preview environment first, so production stays untouched until changes pass review. ## Core Features & Use Cases - Sandbox-Only Deploys: Keeps production and preview outputs isolated at both build-time and deploy-time, with a checklist of required paths and build modes before any release. - Visual Review Loop: Combines lint, build, deploy, HTTP verification, and screenshot comparison into one repeatable QA cycle for frontend changes. - Small-Checkpoint Discipline: Encourages one commit per meaningful UI adjustment so changes are easy to review, revert, and explain. - Use Case: You need to adjust the layout of a marketing page. Use this Skill to build locally, deploy only to the preview path, capture screenshots of the changed area, gather feedback, and iterate in small steps before proposing a production release. ## Quick Start Use the sandbox-ui-iteration skill to deploy my layout changes to the preview environment and run a visual review before touching production.
