Provides exact migration patterns for React string refs (ref="name" + this.refs.name) to React.createRef() in class components. Use this skill whenever migrating string ref usage - including single element refs, multiple refs in a component, refs in lists, callback refs, and refs passed to child components. Always use this skill before writing any ref migration code - the multiple-refs-in-list pattern is particularly tricky and this skill prevents the most common mistakes. Use it for React 18.3.1 migration (string refs warn) and React 19 migration (string refs removed).

- Provides exact migration patterns for React string refs (ref="name" + this.refs.name) to React.createRef() in class components. Use this skill whenever migrating string ref usage - including single element refs, multiple refs in a component, refs in lists, callback refs, and refs passed to child components. Always use this skill before writing any ref migration code - the multiple-refs-in-list pattern is particularly tricky and this skill prevents the most common mistakes. Use it for React 18.3.1 migration (string refs warn) and React 19 migration (string refs removed).
React 18 String Refs Migration
String refs (ref="myInput" + this.refs.myInput) were deprecated in React 16.3, warn in React 18.3.1, and are removed in React 19.
Quick Pattern Map
| Pattern | Reference | |---|---| | Single ref on a DOM element | → patterns.md#single-ref | | Multiple refs in one component | → patterns.md#multiple-refs | | Refs in a list / dynamic refs | → patterns.md#list-refs | | Callback refs (alternative approach) | → patterns.md#callback-refs | | Ref passed to a child component | → patterns.md#forwarded-refs |
Scan Command
# Find all string ref assignments in JSX
grep -rn 'ref="' src/ --include="*.js" --include="*.jsx" | grep -v "\.test\."
# Find all this.refs accessors
grep -rn "this\.refs\." src/ --include="*.js" --include="*.jsx" | grep -v "\.test\."
Both should be migrated together - find the ref="name" and the this.refs.name accesses for each component as a pair.
The Migration Rule
Every string ref migrates to React.createRef():
- Add
refName = React.createRef();as a class field (or in constructor) - Replace
ref="refName"→ref={this.refName}in JSX - Replace
this.refs.refName→this.refName.currenteverywhere

Audit MCP (Model Context Protocol) server configurations for security issues. Use this skill when: - Reviewing .mcp.json files for security risks - Checking MCP server args for hardcoded secrets or shell injection patterns - Validating that MCP servers use pinned versions (not @latest) - Detecting unpinned dependencies in MCP server configurations - Auditing which MCP servers a project registers and whether they're on an approved list - Checking for environment variable usage vs. hardcoded credentials in MCP configs - Any request like "is my MCP config secure?", "audit my MCP servers", or "check .mcp.json" keywords: [mcp, security, audit, secrets, shell-injection, supply-chain, governance]

Enable code intelligence (go-to-definition, find-references, hover, type info) for any programming language by installing and configuring an LSP server for Copilot CLI. Detects the OS, installs the right server, and generates the JSON configuration (user-level or repo-level). Use when you need deeper code understanding and no LSP server is configured, or when the user asks to set up, install, or configure an LSP server.

github/gsap-framer-scroll-animation
development
VerifiedTrustedOfficial
Use this skill whenever the user wants to build scroll animations, scroll effects, parallax, scroll-triggered reveals, pinned sections, horizontal scroll, text animations, or any motion tied to scroll position — in vanilla JS, React, or Next.js. Covers GSAP ScrollTrigger (pinning, scrubbing, snapping, timelines, horizontal scroll, ScrollSmoother, matchMedia) and Framer Motion / Motion v12 (useScroll, useTransform, useSpring, whileInView, variants). Use this skill even if the user just says "animate on scroll", "fade in as I scroll", "make it scroll like Apple", "parallax effect", "sticky section", "scroll progress bar", or "entrance animation". Also triggers for Copilot prompt patterns for GSAP or Framer Motion code generation. Pairs with the premium-frontend-ui skill for creative philosophy and design-level polish.
