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

Trigger: After successfully locating and focusing on the target substance.
Prerequisite: The substance must be accessible (e.g., in inventory, in an open container).
Next Step: This skill should be completed before setting up any apparatus (e.g., activating a stove, connecting electrical components).

Core Procedure

Identify Target Substance: Confirm the exact name and location of the substance to be prepared.
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.
Select & Validate Container: Choose the most suitable empty container. If uncertain, examine it to confirm it's empty.
Execute Transfer: Use the move [SUBSTANCE] to [CONTAINER] action.
Verify: Briefly check the container's contents to confirm the transfer was successful.

Key Considerations

Container State: All containers are pre-opened. Do not use open or close actions.
Efficiency: Prefer containers in the same room to minimize teleport use.
Substance Integrity: If the substance is temperature-sensitive (e.g., chocolate in a fridge), moving it to a room-temperature container is part of preparation.
Error Handling: If the transfer fails (e.g., container not found), look around again and consult the bundled reference for common container names.

Example

Scenario: You need to melt chocolate as part of a heating task.

You have already located chocolate in the fridge in the kitchen.
Run look around to scan for containers. You see: metal pot (empty, on counter), glass beaker (empty, on shelf), ceramic cup (contains water).
Select metal pot as the best option (metal, empty, suitable for heating).
Run examine metal pot to confirm it is empty.
Run move chocolate to metal pot.
Run examine metal pot — output confirms: "metal pot (containing chocolate)".

Proceed to the next skill (e.g., apparatus setup) only after this verification.
