What problem does it solve? Building Salesforce Lightning Design System (SLDS) interfaces often leads to invented CSS hooks, hardcoded values, and deprecated tokens because agents guess artifact names instead of verifying them. This Skill enforces a verify-before-use workflow against real SLDS metadata so generated UI code passes the official SLDS linter. ## Core Features & Use Cases - Component Selection Hierarchy: Guides the choice between Lightning Base Components, SLDS Blueprints, styling hooks, and custom CSS across LWC, React, Vue, Angular, and vanilla HTML. - Verified Artifact Lookup: Bundled search scripts query 523 styling hooks, 1,147 utility classes, 85 blueprint YAML specs, and 1,732 icons so no invented classes or hooks reach the output. - Mandatory Validation Workflow: Runs the @salesforce-ux/slds-linter plus manual checklists covering hook fallbacks, color pairing, spacing, typography, and icon accessibility. - Use Case: When asked to build a confirmation modal in LWC, the Skill selects LightningModal, verifies the error color hooks and warning icon via search scripts, applies utility classes for spacing, and validates the result against the checklist before delivery. ## Quick Start Ask the agent to build an SLDS-styled component such as a responsive card grid with status badges and icons for your LWC or React app.
