Scienceworld Container Inspector

Skill: Container/Device Inspector

When to Use

Trigger this skill when you need to:

1. Verify Placement: Confirm an object has been successfully moved into a target container (e.g., "Is the metal pot in the blast furnace?").
2. Monitor State Change: Check if the contents of a container have changed state due to a process (e.g., "Has the lead melted into liquid lead?").
3. Inventory Check: List all items currently stored inside an open container or device.

Core Instruction

Always use the exact action: look at <CONTAINER_NAME>

• Replace <CONTAINER_NAME> with the precise name of the target object (e.g., blast furnace, cupboard, tin cup).
• This action returns a structured observation detailing the container's state and a list of its contents.

Expected Output & Interpretation

The observation will follow this general pattern: [CONTAINER], which is [STATE]. The [CONTAINER] door is [OPEN/CLOSED]. In the [CONTAINER] is: \n\t[LIST OF CONTENTS]

Key Information to Extract:

1. Container State: Is it activated/turned on? (e.g., "which is turned on").
2. Door State: Is it open or closed? You can only see contents if the door is open.
3. Contents List: A nested list of all objects inside. Pay close attention to:
   • Item Names: (e.g., a metal pot).
   • Substance States: The description may reveal state changes (e.g., a substance called liquid lead vs. a substance called lead).
   • Nested Containers: Contents may themselves be containers (e.g., a metal pot (containing a substance called lead)).

Example from Trajectory

Action: look at blast furnace Observation: a blast furnace, which is turned on. The blast furnace door is open. In the blast furnace is: \n\ta metal pot (containing a substance called liquid lead) Interpretation: The blast furnace is active and open. It contains one item: a metal pot, which itself contains liquid lead. This confirms the heating process was successful and the lead has melted.

Integration with Other Actions

This skill is often used in a sequence:

1. move <ITEM> to <CONTAINER> (Place an item).
2. look at <CONTAINER> (This skill - verify placement).
3. activate <CONTAINER> (Start a process).
4. look at <CONTAINER> (This skill - monitor state change).
5. use <TOOL> on <CONTENT> (Proceed based on observed state).

Error Handling

• If the look at action fails or returns an unexpected result, first verify the object's name is correct by using look around or examine.
• If the container door is closed, you must open it before using this skill.
• The skill only inspects; it does not manipulate contents. Use pick up, move, or use for manipulation.
