What problem does it solve? Building project-scheduling Gantt charts or booking/event calendars in React requires knowing reui's exact API surface — prop names, callback contracts, and data shapes that silently break when guessed. This Skill provides evidence-audited API references so generated scheduling UI code works against the real @reui/gantt and @reui/event-calendar components. ## Core Features & Use Cases - Gantt component patterns: Composition contract, GanttEvent/GanttResource data shapes, view configuration props, drag/resize commit gating via onEventUpdate, and RFC 5545 recurrence handling. - Event Calendar patterns: Six views (month, week, day, N-day, agenda, resource), EventCalendarApi methods, timezone-safe rendering, and headless subscription hooks. - Use Case: A developer asks for a resource-timeline Gantt with drag-and-drop task rescheduling; the Skill directs reading references/gantt-api.md first, then produces code using the correct controlled/uncontrolled props and the single onEventUpdate commit gate. ## Quick Start Ask the agent to build a Gantt scheduling view or event calendar UI with reui, and it will consult the bundled API references before writing any component code.
