react-native-reanimated-dnd: Skill for Claude Code

.agents/skills/reanimated-dnd/SKILL.md

reanimated-dnd is a skill for Claude Code from entropyconquers/react-native-reanimated-dnd. It costs 42 tokens per session (9,281 once invoked), scanned A, original, MIT.

A drag-and-drop library for React Native, the framework for building mobile apps with JavaScript or TypeScript. It supports reorderable lists and grids as well as areas where items can be dropped.

In plain words
What is it for?
Use it for draggable items, sortable vertical or horizontal lists, sortable two-dimensional grids, drop zones, movement limits, collision detection, and lists with different item heights.
Why use it?
It provides the building blocks and setup guidance needed to let users move and reorder items in a React Native app.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; installed under .agents/ (shared by several agents).

This is entropyconquers/react-native-reanimated-dnd's own configuration. It tells Claude Code how to work on react-native-reanimated-dnd itself, so it is not a mod to install elsewhere.

About the project

React Native Reanimated DnD is a drag-and-drop component library for React Native mobile applications. Developers use it to build draggable elements, sortable lists and grids, and interfaces with collision detection and animated gestures. The catalogue skill provides assistance for working with this library.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reanimated-dnd scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

react-native-reanimated-dnd Integration Skill

Version: 2.0.0 Category: UI / Drag and Drop Platform: React Native (requires react-native-reanimated >=4.2.0, react-native-gesture-handler >=2.28.0, react-native-worklets >=0.7.0)


Overview

react-native-reanimated-dnd provides performant drag-and-drop primitives for React Native. It offers both high-level components and low-level hooks for:

  • Drag & Drop: Move items between drop zones
  • Sortable Lists: Vertical and horizontal reorderable lists
  • Sortable Grids: 2D grids with insert or swap reordering
  • Constraints: Axis locking, bounded dragging, collision detection
  • Dynamic Heights: Auto-measuring variable-height items in lists

All animations run on the UI thread via Reanimated worklets.


Installation

npm install react-native-reanimated-dnd
# or
yarn add react-native-reanimated-dnd

Peer dependencies (must be installed separately)

npm install react-native-reanimated react-native-gesture-handler react-native-worklets

Required setup

Wrap your app root with GestureHandlerRootView:

import { GestureHandlerRootView } from 'react-native-gesture-handler';

export default function App() {
  return (
    <GestureHandlerRootView style={{ flex: 1 }}>
      {/* Your app content */}
    </GestureHandlerRootView>
  );
}

Core Architecture

DropProvider (context - required for Draggable/Droppable)
├── Draggable (items that can be picked up)
│   └── Draggable.Handle (optional restricted drag area)
└── Droppable (zones that accept drops)

Sortable (self-contained vertical/horizontal list)
├── SortableItem (individual reorderable item)
│   └── SortableItem.Handle (optional restricted drag area)

SortableGrid (self-contained 2D grid)
├── SortableGridItem (individual grid cell)
│   └── SortableGridItem.Handle (optional restricted drag area)

Key rule: All data items MUST have an id: string property for tracking.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
