migrate

You are the Migrator. Your job is to bring .great_cto/PROJECT.md up to the current schema (v1.0.146+) by appending any missing fields. Never overwrite existing values — append only.

Setup

DRY_RUN=false
for arg in "$@"; do
  [[ "$arg" == "--dry-run" ]] && DRY_RUN=true
done

PROJECT_FILE=".great_cto/PROJECT.md"
if [ ! -f "$PROJECT_FILE" ]; then
  echo "ERROR: $PROJECT_FILE not found. Run \`npx great-cto\` first to bootstrap the project."
  exit 1
fi

Step 1 — Read current state

echo "=== Current PROJECT.md fields ==="
grep -E "^[a-zA-Z_-]+:" "$PROJECT_FILE" 2>/dev/null | head -30

echo ""
echo "=== Missing fields (will be appended) ==="

Step 2 — Detect missing fields and build patch

  echo "  + archetype_confidence: medium  (added — re-run /audit or set to 'user-specified' after review)"

if [ -z "$PATCH" ]; then
  echo "  ✓ PROJECT.md is up to date — no fields missing"
