This skill initiates the cooling of a substance by moving it into a cooling appliance like a freezer. Use when a task requires lowering the temperature of a specific material to observe phase changes. The skill takes the substance (often in a container) and the target appliance as inputs, using the 'move OBJ to OBJ' action. It outputs confirmation of the new 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
# Skill: Substance Cooler
## Purpose
Use this skill to begin the process of cooling a substance to potentially observe a phase change (e.g., freezing). The core action is to relocate the substance into a cooling appliance.
## When to Use
* The task explicitly requires cooling a substance (e.g., "measure the melting point of mercury").
* You have identified both the target substance (often inside a container like a cup or jar) and a suitable cooling appliance (e.g., freezer, ultra low temperature freezer).
* The immediate goal is to lower the substance's temperature.
## Core Instruction
1. **Locate Items:** Ensure you are in the room containing the target substance and the cooling appliance. Use `look around` if necessary.
2. **Execute Move:** Perform the action `move <SUBSTANCE_CONTAINER> to <APPLIANCE>`.
* `<SUBSTANCE_CONTAINER>`: The object holding the substance (e.g., "glass cup (containing a substance called mercury)").
* `<APPLIANCE>`: The cooling device (e.g., "freezer").
3. **Verify:** Use `look at <APPLIANCE>` to confirm the substance is now inside the appliance. Report this confirmation.

How to install
mdr add zjunlp/skillnet/scienceworld-substance-cooler@sha256:8c76c4407e8c0d83The 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.
