Alfworld Receptacle Preparer

This skill verifies and prepares a target receptacle for receiving an object. It is triggered before placing an item into a receptacle (e.g., a garbage can) to ensure the receptacle is accessible and suitable. The skill involves navigating to the receptacle, observing its state (e.g., open/closed, occupied), and performing any necessary preparatory actions like opening it, resulting in a ready-to-use target location.

Instructions

Trigger: This skill is invoked when the agent's goal requires placing an object into a target receptacle (e.g., "put X in/on Y").

Core Procedure

Navigate: Use go to {target_receptacle} to move to the target receptacle's location.
Observe: Upon arrival, carefully read the environment's observation. It will describe the receptacle's state and any contents.
Analyze & Prepare: Based on the observation, determine if the receptacle is ready.
- Ready State: The receptacle is described as present and accessible (e.g., "On the garbagecan 1, you see a cd 1."). No further action is needed. Proceed to place the object.
- Blocked/Closed State: If the receptacle is closed, latched, or obstructed, use the appropriate action (open {recep}, toggle {obj} {recep}) to prepare it.
- Invalid Target: If the observation indicates the receptacle does not exist or cannot be interacted with ("Nothing happened"), you must abort this skill and re-plan your task strategy.
Confirm: After any preparatory action, observe the environment's feedback to confirm the receptacle is now ready.

Key Principles

Efficiency: This skill is a preparatory step. Do not spend turns searching for the object to be placed here. That is a separate "search" skill.
Context: The observation text is your only source of truth about the receptacle's state. Interpret it literally.
Idempotency: If the receptacle is already ready, this skill completes immediately with no action required beyond observation.

Example from Trajectory

Goal Context: "find two pen and put them in garbagecan." Skill Execution:

Thought: "I'll check the garbage can first to ensure it's open and ready to receive items."
Action: go to garbagecan 1
Observation: "On the garbagecan 1, you see a cd 1."
Analysis: The garbage can is present and accessible (a CD inside does not block new items). It is ready.
Outcome: Skill completes. The agent proceeds to put pen 3 in/on garbagecan 1.
