In the large skillet, heat the remaining 3 tablespoons of oil until shimmering. Season the shrimp with salt and a pinch of crushed red pepper and cook over high heat, tossing once or twice, until barely cooked, about 1 1/2 minutes. Add the basil and pasta along with the reserved pasta cooking water and cook, tossing, until the shrimp are white throughout and the pasta is coated in a light sauce, about 1 minute. Transfer the pasta to bowls and scatter the cherry tomatoes all around. Top with the tomato sauce and bread crumbs. Serve right away.
