Skill: Open Receptacle

Purpose

Open a closed container to reveal its contents for subsequent interaction.

When to Use

Use this skill when:

• You need to take an item from inside a closed receptacle
• You need to put an item into a closed receptacle
• You observe a receptacle is closed (e.g., "The fridge 1 is closed")
• The task requires accessing items inside containers

Input Format

The skill requires a receptacle identifier as input. This should match the environment's naming convention (e.g., "fridge 1", "microwave 1", "drawer 3").

Execution Steps

1. Verify receptacle state: Check if the receptacle is mentioned as "closed" in the observation
2. Navigate to receptacle: Use go to {recep} if not already at the location
3. Execute open action: Use open {recep} where {recep} is the receptacle identifier
4. Process result: The environment will respond with the interior contents or an error

Expected Outcomes

• Success: Observation showing the receptacle is open and listing contained items
• Failure: "Nothing happened" indicates the action was invalid (e.g., already open, wrong identifier)
