name: alfworld-receptacle-preparer
description: 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
1. **Navigate:** Use `go to {target_receptacle}` to move to the target receptacle's location.
2. **Observe:** Upon arrival, carefully read the environment's observation. It will describe the receptacle's state and any contents.
3. **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.
4. **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:**
1. Thought: "I'll check the garbage can first to ensure it's open and ready to receive items."
2. Action: `go to garbagecan 1`
3. Observation: "On the garbagecan 1, you see a cd 1."
4. Analysis: The garbage can is present and accessible (a CD inside does not block new items). It is **ready**.
5. Outcome: Skill completes. The agent proceeds to `put pen 3 in/on garbagecan 1`.

- 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-appliance-preparerPrepares 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.
- 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.
