Use when you need to transfer a target substance into an appropriate container for processing (e.g., a pot for heating, a beaker for mixing). Trigger after acquiring the substance and before setting up an apparatus. Selects a suitable empty container and moves the substance into it.
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
# Substance Preparation Skill
## Purpose
Prepare a target substance for subsequent processing (e.g., heating, mixing) by transferring it from its current location into an appropriate, empty container.
## When to Use
1. **Trigger:** After successfully locating and focusing on the target substance.
2. **Prerequisite:** The substance must be accessible (e.g., in inventory, in an open container).
3. **Next Step:** This skill should be completed **before** setting up any apparatus (e.g., activating a stove, connecting electrical components).
## Core Procedure
1. **Identify Target Substance:** Confirm the exact name and location of the substance to be prepared.
2. **Scan Environment for Containers:** Look for empty, process-appropriate containers in the current room. Priority order:
* **Primary:** Metal pots, beakers, or bowls (for heating/mixing).
* **Secondary:** Ceramic/glass cups, jars (if primary not available).
* **Avoid:** Containers already holding items or substances.
3. **Select & Validate Container:** Choose the most suitable empty container. If uncertain, `examine` it to confirm it's empty.

How to install
mdr add zjunlp/skillnet/scienceworld-substance-preparator@sha256:c45282898a4da1f2The 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.
