# Skeleton Dev > Build UI with Skeleton UI v4 (any framework). Use when creating, editing, or reviewing any component that uses Skeleton UI — buttons, modals, tabs, navigation, forms, cards, avatars, etc. Also use when questions involve Skeleton presets, color pairings, composed component patterns, or theming. Supports Svelte, React, and framework-agnostic usage. Use when this capability is needed. - Skill: `tomevault-io/skeleton-dev` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/skeleton-dev` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/skeleton-dev/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/skeleton-dev --- # Skeleton Dev Reference Skeleton UI v4 LLM-optimized docs before writing or reviewing Skeleton components. ## Docs Sources First fetch `https://www.skeleton.dev/llms.txt` — this is the comprehensive index of all available LLM docs. Then detect the framework from the project (package.json, file extensions, imports) and fetch the matching full docs: | Framework | URL | |-----------|-----| | Svelte | `https://www.skeleton.dev/llms-svelte.txt` | | React | `https://www.skeleton.dev/llms-react.txt` | Use WebFetch to retrieve the correct reference **before starting any task**. ## Usage 1. Fetch `llms.txt` index to check for any new/updated doc URLs 2. Confirm Skeleton version in `package.json`/lockfiles; if not v4, pause and alert the user before proceeding. 3. Detect framework from the project context. If unclear, ask the user; if still ambiguous, fetch both Svelte/React docs but only read the relevant sections. 4. Fetch the matching framework-specific docs (reuse a cached copy during the session unless `llms.txt` changed). 5. Read the relevant sections for the components needed 6. Write or review code following the documented patterns --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/finnan444) — claim your Tome and manage your conversions.
