name: scienceworld-substance-cooler
description: 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.

# 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.
## Important Notes
* **Prerequisite:** The appliance door must be open. The trajectory shows all containers are already open, so this should not require a separate `open` action.
* **This is an Initialization Skill:** This skill only *starts* the cooling process. Subsequent skills or actions (like `use thermometer on <SUBSTANCE>`) are required to monitor temperature changes and observe the phase transition.
* **Inputs:** The skill requires the names of the substance container and the target appliance as identified in the environment observations.
* **Output:** A confirmation observation stating the substance is now inside the appliance.
## Example from Trajectory
**Trigger:** Task requires measuring the melting point of mercury.
**Action:** `move glass cup (containing a substance called mercury) to freezer`
**Verification:** `look at freezer` yields "In the freezer is: a glass cup (containing a substance called mercury)."
**Output:** "The mercury in its glass cup has been placed into the freezer to begin cooling."Trust audit

Is Scienceworld Substance Cooler safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can Scienceworld Substance Cooler access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
What do I need installed to use Scienceworld Substance Cooler?
Its own instructions reference open. Dependencies are pinned to exact versions.
