name: alfworld-object-storer description: Use when the agent is holding an object and needs to place it into a target receptacle in ALFWorld. This skill checks receptacle suitability, opens closed containers if needed, and executes the put command to store the object. It handles both open surfaces (countertops, beds) and closed containers (drawers, cabinets).

Skill: Object Storer

When to Use

Trigger this skill when:

1. The agent is holding the target object (optionally cleaned/heated/cooled as required)
2. A suitable storage receptacle has been identified
3. The agent needs to execute the final placement step

Core Workflow

1. Validate Prerequisites

• Confirm the agent is holding {object_name} (check inventory)
• Confirm the agent is at the location of {target_receptacle}
• If not at the receptacle, navigate there first: go to {target_receptacle}

2. Check Receptacle State

Evaluate the receptacle before placing:

Receptacle State	Action
Open and empty/suitable	Proceed with put
Closed (drawer, cabinet, safe)	open {target_receptacle} first, then put
Unsuitable (wrong type, full)	Abort and search for alternative receptacle

3. Execute Storage

• Run: put {object_name} in/on {target_receptacle}
• Check the observation for confirmation

4. Verify Placement

• A successful placement updates the receptacle contents in the observation
• If the observation confirms the object is now in/on the receptacle, storage is complete

Example

Task: "Clean the knife and put it in a drawer."

> go to drawer 1
The drawer 1 is closed.
> open drawer 1
You open the drawer 1. The drawer 1 is open. In it, you see nothing.
> put knife 1 in/on drawer 1
You put the knife 1 in/on the drawer 1.

Result: knife 1 is now stored in drawer 1. Task complete.

Example 2 — Open surface:

> go to bed 1
On the bed 1, you see a pillow 1.
> put cellphone 2 in/on bed 1
You put the cellphone 2 in/on the bed 1.

Error Handling

• "Nothing happened": The agent may not be holding the object, or the receptacle name is incorrect. Verify with inventory and re-check the receptacle identifier.
• Receptacle unsuitable: If the receptacle is not appropriate for the object, search for an alternative using the object-locator skill.
• Agent not at receptacle: Navigate to the receptacle with go to {target_receptacle} before attempting put.
