This skill verifies and prepares a target receptacle for receiving an object. It is triggered before placing an item into a receptacle (e.g., a garbage can) to ensure the receptacle is accessible and suitable. The skill involves navigating to the receptacle, observing its state (e.g., open/closed, occupied), and performing any necessary preparatory actions like opening it, resulting in a ready-to-use target location.
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
# Instructions
**Trigger:** This skill is invoked when the agent's goal requires placing an object into a target receptacle (e.g., "put X in/on Y").
## Core Procedure
1. **Navigate:** Use `go to {target_receptacle}` to move to the target receptacle's location.
2. **Observe:** Upon arrival, carefully read the environment's observation. It will describe the receptacle's state and any contents.
3. **Analyze & Prepare:** Based on the observation, determine if the receptacle is ready.
* **Ready State:** The receptacle is described as present and accessible (e.g., "On the garbagecan 1, you see a cd 1."). No further action is needed. Proceed to place the object.
* **Blocked/Closed State:** If the receptacle is closed, latched, or obstructed, use the appropriate action (`open {recep}`, `toggle {obj} {recep}`) to prepare it.
* **Invalid Target:** If the observation indicates the receptacle does not exist or cannot be interacted with ("Nothing happened"), you must abort this skill and re-plan your task strategy.
4. **Confirm:** After any preparatory action, observe the environment's feedback to confirm the receptacle is now ready.

How to install
mdr add zjunlp/skillnet/alfworld-receptacle-preparer@sha256:04afc73e8e81493fThe 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.
