React development principles from official documentation. Teaches component purity, state management, effects, refs, reducers, context, and event handling patterns. Use when writing React components with hooks, managing state, synchronizing with external systems, debugging re-renders, or choosing between state management approaches.
Standardizes UX states for data fetching flows (loading, error, empty, success) and complex multi-view UI patterns. Provides state machine approach recommendations, loading skeletons, error boundaries, and empty state components. Use when implementing "loading states", "error handling", "empty states", or "state machines".
Provides comprehensive guidance for Pinia state management including stores, state, getters, actions, plugins, and TypeScript support. Use when the user asks about Pinia, needs to manage application state, create stores, implement state persistence, or migrate from Vuex.
LangGraph workflow patterns for state management, routing, parallel execution, supervisor-worker, tool calling, checkpointing, human-in-loop, streaming, subgraphs, and functional API. Use when building LangGraph pipelines, multi-agent systems, or AI workflows.
Nuxt 4 data management: composables, data fetching with useFetch/useAsyncData, and state management with useState and Pinia. Use when: creating custom composables, fetching data with useFetch or useAsyncData, managing global state with useState, integrating Pinia, debugging reactive data issues, or implementing SSR-safe state patterns. Keywords: useFetch, useAsyncData, $fetch, useState, composables, Pinia, data fetching, state management, reactive, shallow reactivity, reactive keys, transform, pending, error, refresh, dedupe, caching
Expert patterns for 2D animation in Godot using AnimatedSprite2D and skeletal cutout rigs. Use when implementing sprite frame animations, procedural animation (squash/stretch), cutout bone hierarchies, or frame-perfect timing systems. Trigger keywords: AnimatedSprite2D, SpriteFrames, animation_finished, animation_looped, frame_changed, frame_progress, set_frame_and_progress, cutout animation, skeletal 2D, Bone2D, procedural animation, animation state machine, advance(0).
Modern React with hooks and functional components. Trigger: When creating components, implementing hooks, managing state, or optimizing.
This skill provides expert-level guidance for implementing VS Code WebView features. Use when creating WebView panels, implementing secure CSP policies, handling Extension-WebView communication, managing WebView state persistence, optimizing WebView performance, or debugging WebView rendering issues. Covers security best practices, message protocols, and VS Code-specific WebView patterns.
Comprehensive Flutter API reference guide covering widgets, Material Design, Cupertino, animations, gestures, navigation, state management, and platform integration. Use when developing Flutter applications and needing detailed API knowledge for widgets, layout, styling, animations, platform channels, or any Flutter SDK functionality. Essential for building cross-platform mobile, web, and desktop applications with Flutter.
Expert ReactFlow architect for building interactive graph applications with hierarchical node-edge systems, performance optimization, and auto-layout integration. Use when Claude needs to create or optimize ReactFlow applications for: (1) Interactive process graphs with expand/collapse navigation, (2) Hierarchical tree structures with drag & drop, (3) Performance-optimized large datasets with incremental rendering, (4) Auto-layout integration with Dagre, (5) Complex state management for nodes and edges, or any advanced ReactFlow visualization requirements.
ALWAYS use when writing code importing "pinia". Consult for debugging, best practices, or modifying pinia.
State machines using Spatie Model States for complex state transitions. Use when working with complex state management, state transitions, or when user mentions state machines, Spatie Model States, state transitions, transition validation.
