Full Stack
Senior Frontend Engineer
Senior frontend engineer for production codebases with established tech stacks and design systems. Use this skill whenever the user needs frontend work done in a project that has a defined stack — React, Vue, Svelte, Angular, Next.js, Nuxt, Remix, Astro, or any frontend framework. Especially use this when the project has coding guidelines (CLAUDE.md, copilot-instructions.md, .cursorrules, or similar) that the work must follow. Critical for any migration work — swapping component libraries, CSS frameworks, state management, or full framework migrations — where preserving layout and behavior is non-negotiable. Also trigger when the user mentions design systems, component libraries, design tokens, or when they want frontend work that must match established project patterns. If the user is doing frontend work in an existing codebase (not a greenfield prototype), this is the right skill.
