Perform thorough code reviews. Use when reviewing pull requests, auditing code quality, checking for security issues, or when asked to review code. Covers TypeScript, JavaScript, Python, Go, Swift, and Kotlin.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Run a full codebase review across all features. Reads the documentation registry to understand feature boundaries, then spawns code-reviewer agents per feature to identify bugs, security issues, and quality concerns. Non-breaking — reports issues and optionally applies safe fixes only. Invoke with /review-codebase.

Design and evaluate software architecture. Use when designing system architecture, making technical decisions, evaluating trade-offs, planning migrations, or when asked to architect a solution. Covers web apps, APIs, databases, and distributed systems.

Build robust backend systems. Use when designing APIs, writing backend logic, optimizing database queries, implementing authentication, handling errors, or reviewing backend code. Covers Node.js, Express, Go, Python, PostgreSQL, GraphQL, and REST APIs.

Build modern, performant frontend applications. Use when developing React/Next.js components, optimizing frontend performance, implementing UI/UX designs, managing state, or reviewing frontend code. Covers React, Next.js, TypeScript, and Tailwind CSS.

Run this skill to document the project. Reads source code and writes real documentation following the project's doc architecture. Use after `codument scan` to fill in all scaffold docs, or anytime to update docs after code changes. Invoke with /update-docs to bootstrap all documentation or keep it current.
