Actionable errors with paste-ready fix prompts, first-party Skills for the dev loop and Cache Components, and tooling that keeps coding agents in sync with your project.

Next.js 16.3 Preview introduces a suite of AI-driven developer experience improvements. Key additions include: automatic AGENTS.md updates so coding agents always read version-matched docs instead of stale training data; three new first-party Skills (next-dev-loop, next-cache-components-adoption, next-cache-components-optimizer) for agent-driven multi-step workflows; agent-browser 0.27 with React DevTools introspection (component tree, re-render profiling, Suspense inspection); actionable errors with copy-as-prompt buttons and structured console output that give agents paste-ready fix prompts for Cache Components issues; a leaner MCP server focused on compilation diagnostics (get_compilation_issues, compile_route); and docs-as-Markdown support via .md URL suffix and llms.txt convention.
