# Skill: Receptacle Operator ## When to Use Use this skill when you need to: 1. **Access a closed receptacle** to place an object inside or take an object out. 2. **Secure an open receptacle** after accessing it (e.g., to conserve energy, maintain cleanliness, or complete a task step). ## Core Decision Logic 1. **Check the receptacle's state** from the observation. - If it reports "is closed" or "is open", note the state. - If the interior is visible (e.g., "In it, you see..."), it is open. 2. **Choose action based on goal**: - **Goal requires interior access** (e.g., "put in microwave", "take from fridge"): - If closed → `open {recep}` - If open → proceed with next step (e.g., `put` or `take`) - **Goal requires securing receptacle** (e.g., after accessing, or for efficiency): - If open → `close {recep}` - If closed → no action needed 3. **Execute the action** using the exact format: `Action: open {recep}` or `Action: close {recep}` ## Example from Trajectory - **Task**: "cool some tomato and put it in microwave" - **Step 1**: At closed fridge → `Action: open fridge 1` - **Step 2**: After checking interior → `Action: close fridge 1` (for efficiency) - **Step 3**: At closed microwave → `Action: open microwave 1` ## Important Notes - Always verify the receptacle state from the latest observation before acting. - The skill only handles `open` and `close` actions. Other actions (like `take`, `put`, `cool`) are separate skills. - If "Nothing happened" is observed after your action, the receptacle may already be in that state—re-check and adjust.
