### backend-development

Design and build production-grade backend systems — APIs, services, databases, authentication, and infrastructure. Use this skill when the user asks to create, refactor, or debug any server-side code: REST or GraphQL APIs, database schemas, auth flows, background jobs, caching layers, webhooks, middleware, microservices, or deployment configs. Also activate when the user mentions Node.js, Python, Go, Rust, Express, Fastify, NestJS, FastAPI, Django, Flask, Gin, Axum, PostgreSQL, MongoDB, Redis, Docker, or any backend framework. Even if the user just says "build the backend" or "add an API," this is the right skill.

### frontend-design

Design and build production-grade frontend interfaces with strong visual identity, accessible markup, and performant code. Use this skill when the user asks to create, redesign, or improve any web UI — landing pages, dashboards, components, marketing sites, web apps, forms, data visualizations, or email templates. Also activate when the user mentions styling, theming, layout, responsiveness, UI polish, design systems, or when any frontend output looks generic and needs elevation. Even if the user does not say "design," activate when the deliverable is user-facing HTML/CSS/JS, React, Vue, Svelte, or similar.

### database-design

Design, build, optimize, and migrate production databases. Use this skill when the user asks to create schemas, write SQL, optimize queries, plan migrations, design data models, set up indexes, troubleshoot slow queries, or work with PostgreSQL, MySQL, SQLite, MongoDB, or Redis. Also activate when the user mentions tables, columns, foreign keys, joins, indexes, migrations, ORMs, connection pooling, or any database-related work. Even if the user just says "set up the database" or "the query is slow," this is the right skill.
