Instructions

Goal

Prepare a specified household appliance for immediate use by ensuring it is in the correct open or closed state. This is a prerequisite step before performing actions like heat, cool, or toggle with the appliance.

Input

• appliance_identifier: The name of the appliance to prepare (e.g., microwave 1, toaster 1, fridge 1).

Core Logic

1. Navigate to the Appliance: First, go to the location of the target appliance.
2. Check State & Prepare: Determine if the appliance needs to be opened or closed based on the intended subsequent action. The standard rule is:
   • For appliances used to contain items for processing (e.g., microwave, oven, fridge), they typically need to be open to receive the item.
   • Use the open {appliance} or close {appliance} action as needed.
3. Confirm Readiness: The skill is complete when the appliance is in the correct state, confirmed by an observation from the environment (e.g., "The microwave 1 is open.").

Important Considerations

• State Awareness: Always observe the environment's feedback after each action (e.g., "The microwave 1 is closed."). Do not assume the state.
• Error Handling: If the action fails (environment outputs "Nothing happened"), the appliance may already be in the desired state. Re-check the observation and proceed.
• Trajectory Insight: Refer to the example in references/trajectory_example.md to see a practical application of this skill in the context of a larger task.

Example

Input: appliance_identifier: microwave 1

Sequence:

1. go to microwave 1 → Observation: "You are at microwave 1. The microwave 1 is closed."
2. open microwave 1 → Observation: "You open the microwave 1. The microwave 1 is open."

Output: "The microwave 1 is open and ready for use."

Output

A confirmation that the appliance is ready, typically in the form of the agent's Thought summarizing the prepared state and the environment's observation.
