name: alfworld-appliance-preparer
description: Prepares a household appliance (microwave, oven, toaster, fridge) for use by ensuring it is in the correct open/closed state. Use when the agent needs to heat, cool, or cook an item and must first open or close the appliance before placing an object inside. Takes an appliance identifier as input and outputs a confirmation that the appliance is ready for the next action.

# 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.

- alfworld-appliance-navigatorNavigates the agent to a target appliance (microwave, stove, fridge, or sinkbasin) needed for object processing. Use when you are holding an object that needs heating, cooling, or cleaning and must move to the correct appliance station. Identifies the required appliance from the task context and executes the movement action.
- alfworld-clean-objectCleans a specified object using an appropriate cleaning receptacle (e.g., sinkbasin). Use when a task requires an object to be in a clean state (e.g., "clean potato", "wash apple") before proceeding. Navigates to the cleaning location, performs the clean action, and confirms the object is now clean.
- alfworld-device-operatorOperates a device or appliance (like a desklamp, microwave, or fridge) to interact with another object. Use when the task requires using a tool on a target item (e.g., "look at laptop under the desklamp", "heat potato with microwave"). Locates both the device and target object, co-locates them, and executes the appropriate use action (toggle, heat, cool, or clean).
- alfworld-environment-scannerPerforms an initial scan of the ALFWorld environment to identify all visible objects and receptacles. Use when you first enter an environment and need to build a mental map for task planning. Processes raw observation text into a structured list of entities, categorizing them as objects or receptacles.
- alfworld-goal-interpreterParses the natural language task goal to extract actionable sub-objectives and required objects. Trigger this skill whenever a new task is assigned to break down complex instructions into clear, sequential targets. It interprets phrases like 'look at X under Y' to identify target objects (pillow), reference objects (desklamp), and spatial relationships (under).
- alfworld-heat-object-with-applianceUses a heating appliance (microwave, stoveburner, oven) to apply heat to a specified object. Use when the task requires warming or cooking an item (e.g., "heat some egg", "warm the mug") and a heating appliance is available. Takes the object name and appliance name as input and outputs the object in a heated state, ready for placement at the task's target location.
- alfworld-inventory-managementUse when the agent must collect and track multiple instances of the same object type in ALFWorld (e.g., "put two cellphone in bed"). This skill maintains a count of collected versus needed objects, guides systematic searching through receptacles, and ensures each found object is placed at the target before searching for the next.
- alfworld-locate-target-objectNavigates to a suspected location and identifies a target object. Use when your goal requires finding a specific object (e.g., "potato", "plate") and its location is not immediately known. Moves to a relevant receptacle (like a fridge or cabinet), checks its contents, and outputs the object's location or confirms its absence.
- alfworld-location-navigatorMoves the agent to a specified receptacle or object location within the Alfworld environment. Use this skill when the agent needs to physically approach a target to inspect or interact with it, such as when checking an object's state or preparing for pickup. The skill takes a target location name as input and executes the 'go to' action, resulting in the agent being positioned at the destination for subsequent operations.
- alfworld-navigation-plannerPlans a path to move the agent between receptacles to search for target objects. Use this when you need to traverse the environment to reach a specific location or systematically explore multiple areas. It takes the current location and destination receptacle as input, and outputs the next 'go to' action to approach the target.
