Context: Next.js 16.2 (March 18, 2026) delivers ~400% faster dev startup via Turbopack improvements, Server Fast Refresh for hot-reloading server code, SRI support, and AI-agent DevTools including AGENTS.md scaffolding and browser-log forwarding. PR #429 is already in progress on the Content SDK repo. This upgrade directly amplifies Content SDK's agent skills value proposition.
Steps:
1. Review and complete PR #429 -- ensure all packages compile and tests pass against Next.js 16.2.1
2. Update `packages/nextjs/package.json` peer dependency to include 16.2.x compatibility
3. Enable Server Fast Refresh in development configuration
4. Update `create-content-sdk-app` Next.js App Router template to target 16.2
5. Document SRI configuration in the starter template's `next.config.ts`
6. Verify Turbopack file system caching still works correctly with Content SDK's build pipeline
7. Test AI-agent DevTools integration with Content SDK's existing AGENTS.md and Skills.md
Acceptance criteria:
All packages build and test against Next.js 16.2.1
`create-content-sdk-app` scaffolds projects targeting Next.js 16.2
Server Fast Refresh works in development mode with Content SDK components
CHANGELOG documents the upgrade
Risks: Next.js 16.2 is a minor release with no breaking changes documented, but Turbopack improvements may surface edge cases in Content SDK's build pipeline. Test thoroughly.
