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.

TOOLKIT_DIR="$(cd "$(dirname "$SKILL_PATH")/../nextjs-migration-toolkit" && pwd)"
if [ ! -f "$TOOLKIT_DIR/package.json" ]; then
  echo "ERROR: nextjs-migration-toolkit is not installed." >&2
  echo "Run: npx skills add blazity/next-migration-skills -s nextjs-migration-toolkit" >&2
