Validation & Testing

Run comprehensive validation checks on migrated code to ensure correctness and catch common migration issues.

NO MIGRATION IS COMPLETE WITHOUT A PASSING BUILD

"It compiles" is not "it works." "The validator passes" is not "the build succeeds." Run every step below. A migration claimed as complete without a passing build is not complete.

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
