This skill opens or closes a receptacle (like a fridge, cabinet, or microwave) to access its interior or secure it. It should be triggered when an object needs to be placed inside/retrieved from a closed container, or when an open container should be closed (e.g., for energy efficiency or task cleanliness). The skill decides the appropriate 'open' or 'close' action based on the receptacle's current state and the task context.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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`

How to install
mdr add zjunlp/skillnet/alfworld-receptacle-operator@sha256:57da9f7c8a0afefcThe line at the top of this page pins the label git:20260307.388baa3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
