And that means every time you spin one up, you're either manually editing .env files or you've got a setup script that looks something like this: #!/bin/bash # conductor.json worktree script — set up isolated environment BRANCH_NAME="${CONDUCTOR_BRANCH_NAME}" SLUG="${BRANCH_NAME//\//_}" SLUG="${SLUG//-/_}" BASE_PORT=3000 USED_PORTS=$(cat ~/.worktree-ports 2>/dev/null || echo "") PORT=$BASE_PORT while echo "$USED_PORTS" | grep -q "^$PORT$"; do PORT=$((PORT + 1)) done echo "$PORT" >> ~/.worktree-ports DB_NAME="myapp_${SLUG}" COMPOSE_PROJECT="myapp_${SLUG}" REDIS_PORT=$((PORT + 1000)) cat > .env.local << EOF PORT=$PORT DB_NAME=$DB_NAME DATABASE_URL=postgres://localhost/$DB_NAME COMPOSE_PROJECT_NAME=$COMPOSE_PROJECT REDIS_URL=redis://localhost:$REDIS_PORT EOF createdb "$DB_NAME" 2>/dev/null || true echo "S
