Skill: Substance Fetcher

Primary Objective

Locate a specified target substance (e.g., chocolate, sodium chloride) within the environment and retrieve it for subsequent processing.

Core Logic & Workflow

1. Identify Target: The target substance name is provided as part of the task initiation (e.g., "Your task is to measure the melting point of chocolate").
2. Search Strategy:

• If the current room does not contain the target, use teleport to [room] to navigate to likely locations (e.g., kitchen, workshop, greenhouse).
• Use look around to survey a room and identify containers.

1. Locate in Container:

• Examine open containers (fridge, cupboard, counter, drawer) listed in the room description.
• The target substance is often found inside a container (e.g., "In the fridge is: chocolate").

1. Retrieval Action:

• If the substance is a portable object, use pick up [substance].
• If the substance is inside another object (e.g., in a pot), use move [substance] to [destination container] to prepare it for use.
• Key Assumption: All containers are already open. Do not use open or close actions.

Critical Constraints & Notes

• Container State: Assume all containers (fridge, cupboard, drawer) are already open. Do not waste actions opening them.
• Action Efficiency: Prefer pick up for direct acquisition. Use move only when necessary to transfer the substance to a specific vessel for an experiment.
• Verification: After retrieval, you may use examine [substance] or check your inventory to confirm success before proceeding to the next phase of the experiment.

Example Execution (Based on Trajectory)

Task Context: "Your task is to measure the melting point of chocolate..."

1. teleport to kitchen
2. look around (Observes: "In the fridge is: chocolate...")
3. pick up chocolate or move chocolate to metal pot

Error Handling

• If the substance is not found in the initially suspected room, teleport to and search other relevant rooms (e.g., workshop for chemicals, greenhouse for plants).
• If the retrieval action fails (e.g., object not found), re-examine the room description with look around to confirm the substance's location and container.
