Create a new Next.js project with FSD (Feature-Sliced Design) architecture, TypeScript, Tailwind CSS, ESLint (flat config), Prettier, and Husky. Use when user asks to create/scaffold/initialize a Next.js project with FSD architecture, or when they want a production-ready Next.js boilerplate with modern tooling setup.

Reference and maintain the project's technology stack including frameworks, languages, databases, testing tools, and third-party services to ensure consistency across the codebase. Use this skill when making technology decisions, adding new dependencies, choosing appropriate tools or libraries, configuring build systems, setting up testing frameworks, or documenting the tech stack. Apply this skill when selecting which framework, library, or tool to use for a given task, when ensuring code follows the conventions of the chosen stack (React patterns, Python idioms, Rails conventions), when integrating third-party services, or when documenting technology choices in README or architecture documentation. This skill ensures all team members use consistent technologies, new additions align with existing stack decisions, technology choices are documented with rationale, and the project maintains coherent patterns rather than mixing conflicting approaches or frameworks.

ALWAYS use this skill BEFORE writing or modifying ANY Rust code (.rs files), even for simple Hello World programs. Enforces Microsoft Rust coding guidelines, applies M-CANONICAL-DOCS documentation, adds compliance comments, and validates against rust-guidelines.txt. This skill is MANDATORY for all Rust development.
