Skill: Tool User for ALFWorld

When to Use

Trigger this skill when:

1. A task requires applying a tool to an object (e.g., cleaning a knife with a sinkbasin, heating food with a microwave)
2. Both the tool and target object are in the agent's possession or within reach
3. The agent knows which interaction verb to use for the task context

Core Workflow

1. Identify Requirements

• Parse the task to determine:
  • Target object: The item to be acted upon (e.g., knife 1, potato 2)
  • Required tool: The appliance or instrument needed (e.g., sinkbasin 1, microwave 1)
  • Interaction type: The action verb (clean, heat, cool, use, examine)

2. Locate and Acquire

• Target object: If not in inventory, navigate to its location and take {object} from {receptacle}
• Tool: Navigate to the tool's location (tools are typically stationary appliances)

3. Execute Interaction

Apply the tool to the object using the correct action syntax:

Interaction	Action Command	Example
Clean	clean {obj} with {tool}	clean knife 1 with sinkbasin 1
Heat	heat {obj} with {tool}	heat potato 2 with microwave 1
Cool	cool {obj} with {tool}	cool apple 1 with fridge 1
Examine	examine {obj}	examine book 3
Use	use {tool}	use desklamp 1

4. Verify Outcome

• Check the environment observation after the action
• A successful interaction changes the object state (e.g., knife 1 becomes clean)
• If the observation says "Nothing happened," the action was invalid
