1# Skill: Receptacle Operator
2 
3## When to Use
4Use this skill when you need to:
51. **Access a closed receptacle** to place an object inside or take an object out.
62. **Secure an open receptacle** after accessing it (e.g., to conserve energy, maintain cleanliness, or complete a task step).
7 
8## Core Decision Logic
91. **Check the receptacle's state** from the observation.
10   - If it reports "is closed" or "is open", note the state.
11   - If the interior is visible (e.g., "In it, you see..."), it is open.
122. **Choose action based on goal**:
13   - **Goal requires interior access** (e.g., "put in microwave", "take from fridge"):
14     - If closed → `open {recep}`
15     - If open → proceed with next step (e.g., `put` or `take`)
16   - **Goal requires securing receptacle** (e.g., after accessing, or for efficiency):
17     - If open → `close {recep}`
18     - If closed → no action needed
193. **Execute the action** using the exact format: `Action: open {recep}` or `Action: close {recep}`

21## Example from Trajectory
22- **Task**: "cool some tomato and put it in microwave"
23- **Step 1**: At closed fridge → `Action: open fridge 1`
24- **Step 2**: After checking interior → `Action: close fridge 1` (for efficiency)
25- **Step 3**: At closed microwave → `Action: open microwave 1`
26 
27## Important Notes
28- Always verify the receptacle state from the latest observation before acting.
29- The skill only handles `open` and `close` actions. Other actions (like `take`, `put`, `cool`) are separate skills.
