Assess and upgrade a Next.js project after resolving the target release from current official documentation. Includes tested automation and breaking-change guidance for the Next.js 15 to 16 migration. Use when the user says 'upgrade Next.js', 'migrate to Next.js 16', 'update my Next.js app', 'run the Next.js codemod', 'my Next.js version is outdated', or when a migration plan or baseline build comparison is needed.

Install the complete plugin to include its agents, hooks, commands, and runtime context.

The portable SKILL.md on its own, without the plugin’s hooks, agents, commands, and companion skills. Use it only when you intentionally want the narrower path.
No required companion skills are declared.
Pass the canonical page to a teammate or keep it close for later.
Run local performance audits on a project without network calls. This skill should be used when the user says 'audit performance', 'check bundle size', 'find large images', 'check for heavy dependencies', 'run a perf audit', 'how big is my bundle', 'optimize images', 'find oversized assets', or before any performance optimization work. Also use when an agent needs baseline metrics before making changes. All scripts output structured JSON to stdout.
