Migration Assessment

Analyze a Next.js Pages Router codebase to determine migration complexity, identify blockers, and produce a go/no-go recommendation.

NO MIGRATION WITHOUT ASSESSMENT FIRST

This skill MUST run before route-conversion, component-migration, data-layer-migration, or migration-planning. Even if the user says "just convert this one page" — run assessment first. Hidden blockers (incompatible dependencies, i18n config, custom webpack) can derail a migration mid-flight.

Toolkit Setup

This skill requires the nextjs-migration-toolkit skill to be installed. All migration skills depend on it for AST analysis.
