SKILL.md

Provide comprehensive guidance for advanced Next.js App Router features including Route Handlers (API routes), Parallel Routes, Intercepting Routes, Server Actions, error handling, draft mode, and streaming with Suspense.

CRITICAL RULE: This codebase has @typescript-eslint/no-explicit-any enabled. Using any will cause build failures.

When work requirements mention a specific filename, follow that instruction exactly. If no name is given, pick the option that best matches the project conventions—app/actions.ts is a safe default for collections of actions, while app/action.ts works for a single form handler.

Guide for advanced Next.js App Router patterns including Route Handlers, Parallel Routes, Intercepting Routes, Server Actions, error boundaries, draft mode, and streaming with Suspense. CRITICAL for server actions (action.ts, actions.ts files, 'use server' directive), setting cookies from client components, and form handling. Use when requirements involve server actions, form submissions, cookies, mutations, API routes, `route.ts`, parallel routes, intercepting routes, or streaming. Essential for separating server actions from client components. Source: wsimmonds/claude-nextjs-skills.
