File contents

Next.js Agent-First Features

Next.js 16.3+ is the first framework designed explicitly for AI-agent-driven development.

Key Features

AGENTS.md (auto-generated docs)

next dev auto-writes version-matched docs pointers into AGENTS.md
Agents read actual docs instead of guessing from training data
Opt-out via agentRules: false in next.config.ts

First-Party Skills (npx-installable)

Install via npx skills add vercel/next.js:

Skill	Purpose
`next-dev-loop`	Full dev feedback loop: drive browser, read console, inspect React tree, follow network requests
`next-cache-components-adoption`	Incremental or direct adoption of Cache Components (`"use cache"`)
`next-cache-components-optimizer`	Optimize routes for instant navigation by growing the static shell

Agent Browser React Introspection

agent-browser v0.27+ can run React DevTools commands from CLI:

# Launch with React DevTools
agent-browser --enable react-devtools

# Inspect component tree
agent-browser react tree
agent-browser react inspect <fiber-id>
agent-browser react renders start
agent-browser react suspense --only-dynamic --json

Actionable Errors (Instant Insights)

Error overlay shows labeled fixes (Stream / Cache / Block) with a "Copy prompt" button that copies a paste-ready agent prompt.

Streamlined MCP Server

Two new tools: get_compilation_issues and compile_route — check compilation without full next build.

Turbopack Improvements (16.3)

~90% less memory (21.5GB → 2GB for vercel.com)
~2.3x faster cached builds
Experimental Rust React Compiler (20-50% faster)
import.meta.glob API support
~15% faster dev cold start

Usage

When building or debugging Next.js projects with an AI agent:

Enable AGENTS.md: Ensure next dev runs in the project so docs are auto-generated
Use next-dev-loop skill: Load it when you need browser-based verification
Run agent-browser with React: agent-browser --enable react-devtools for component inspection
Copy actionable error prompts: Use the error overlay's "Copy prompt" button for instant fixes
Cache Components optimizer: Run after building to optimize routes for instant nav

Pitfalls

16.3 is on @preview npm tag — stable expected in weeks
AGENTS.md is auto-overwritten each next dev run — don't manually edit it
agent-browser React DevTools requires --enable react-devtools flag
