In a large skillet over medium heat, combine the hoisin sauce, soy sauce, oyster sauce, and sweet chili sauce; cook, stirring, 1–2 minutes until warmed and combined, then transfer to a bowl.
Heat the same skillet over medium heat and add the coconut oil.
Season the chicken pieces with salt and pepper, add to the skillet, and cook until browned on all sides, about 6–8 minutes.
Stir together the chili garlic sauce and honey, add to the chicken, cook 1–2 minutes to glaze, then transfer the chicken to a bowl.
Add the minced shallots, garlic, and sliced red pepper to the skillet and cook until softened, about 5 minutes.
Return the reserved sauce and the cooked chicken to the skillet and cook 1–2 minutes to heat through and combine flavors.
Add the sliced scallions and spiralized zucchini to the skillet; toss to coat and cook 2–3 minutes, until the zucchini softens but is not mushy.
Toss in the chopped roasted peanuts and drizzle with hot chili sesame oil; remove from heat.
Serve immediately topped with fresh Thai basil.
