name: alfworld-receptacle-finder
description: Searches for a suitable empty or appropriately occupied receptacle (like a shelf or table) to place an object. Use when you are holding an object that needs to be stored or placed and must find a receptacle that meets the placement criteria. Examines candidate receptacles by navigating to and inspecting each one until a suitable location is found.

# Instructions
**Trigger:** Use this skill when you have an object in your inventory that needs to be stored or placed, and you must find a suitable receptacle (e.g., shelf, table, basin).
## Core Procedure
1. **Identify Target Object:** Confirm the object you are holding and its state (e.g., `soapbar 1`, `clean`).
2. **Survey Environment:** Use `go to {recep}` actions to navigate to and visually inspect candidate receptacles from the observation list.
3. **Evaluate Candidates:** For each receptacle, assess its suitability:
* **Primary Goal:** Find an **empty receptacle**.
* **Fallback:** If no empty receptacle is available, identify one that can logically accommodate the object without conflict (e.g., a shelf with a tissuebox may still have space for a soapbar).
4. **Select & Place:** Navigate to the chosen suitable receptacle and execute `put {obj} in/on {recep}`.
## Key Considerations
* **Object State:** Ensure the object meets any required pre-conditions (e.g., `clean`) before searching for a receptacle. Use skills like `clean` if necessary.
* **Efficiency:** Prioritize receptacles that are logically appropriate for the object (e.g., a `shelf` for a `soapbar` over a `toilet`).
* **Observation Parsing:** Carefully read the observation after each `go to` action. The line "On the {recep}, you see..." lists its contents. "you see nothing." indicates it is empty.
* **Invalid Actions:** If an action fails ("Nothing happened"), re-evaluate your target and try a different receptacle or confirm the object is in your inventory.
## Example
**Scenario:** You are holding `soapbar 1` (clean) and need to find an empty shelf to place it.
```
Thought: I need to find an empty shelf for the soapbar. I'll check shelf 1 first.
Action: go to shelf 1
Observation: On the shelf 1, you see a tissuebox 1.
Thought: Shelf 1 has items. Let me try shelf 2.
Action: go to shelf 2
Observation: On the shelf 2, you see nothing.
Action: put soapbar 1 in/on shelf 2
Observation: You put the soapbar 1 in/on the shelf 2.
```
**Result:** Found an empty shelf and placed the soapbar on it.

- 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.
