Cools a held object using an appropriate cooling appliance such as a fridge or freezer. Use when the task requires reducing the temperature of an object (e.g., "cool some pot", "chill the mug") and the agent is already holding the object. Performs the ALFWorld `cool` action and outputs the cooled object ready for subsequent placement or serving steps.
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: Cool Held Object
## Purpose
Use this skill when you are holding an object (e.g., `pot 1`) that needs to be cooled and you are at the location of a valid cooling receptacle (e.g., `fridge 1`). The skill executes the `cool` action to change the object's state.
## Prerequisites
1. **Object in Hand:** You must already be holding the target object (e.g., `pot 1`).
2. **At Cooling Receptacle:** You must be at the location of the cooling appliance (e.g., `fridge 1`). Use `go to {recep}` to navigate first if needed.
3. **Valid Receptacle:** The receptacle must be a valid target for the `cool` action (e.g., fridge, freezer). The environment will validate this.
## Core Action
Execute the `cool` action with the format: `cool {obj} with {recep}`.
## Execution Flow
1. **Verify State:** Confirm you are holding the object and are at the cooling receptacle's location.
2. **Execute:** Perform the `cool` action.
3. **Verify Outcome:** The expected observation is "You cool the {obj} using the {recep}." If the observation is "Nothing happened," the action was invalid—check the prerequisites or try a different receptacle.

How to install
mdr add zjunlp/skillnet/alfworld-object-cooler@sha256:d1f241658b8a6c5bThe line at the top of this page pins the label git:20260316.e08426e, 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.
