name: scienceworld-substance-fetcher description: Locates and retrieves a target substance or material from a container in the environment. Use this skill when the task requires processing a specific substance (e.g., chocolate, sodium chloride, a chemical) and you need to find and acquire it. Searches rooms and containers (fridge, cupboard, counter) and retrieves the substance via pick up or move actions.

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.
3. 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").
4. 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.
