name: alfworld-receptacle-navigator
description: Plans and executes movement to a target receptacle within the ALFWorld environment. Use when the agent needs to reach a specific location before interacting with objects there (e.g., go to fridge to cool an item, go to garbagecan to dispose of an item). Takes a receptacle identifier as input, executes the `go to` action, and outputs confirmation of arrival at the destination.

# Skill: Receptacle Navigator
## Purpose
Navigate to a specified receptacle (e.g., `fridge 1`, `garbagecan 1`, `diningtable 1`) in an ALFWorld household environment. This is a foundational skill for positioning the agent to perform subsequent object interactions.
## When to Use
Trigger this skill when the agent's plan requires:
1. **Accessing a location** to interact with an object there (e.g., "go to fridge to cool an item").
2. **Interacting with the receptacle itself** (e.g., "go to garbagecan to dispose of an item").
## Core Logic
1. **Input Parsing:** Extract the target receptacle name (e.g., `fridge 1`) from the current task context or observation.
2. **Action Execution:** Output the ALFWorld action: `go to {target_receptacle}`.
3. **Success Verification:** Confirm the action was successful by checking the observation for evidence of arrival (e.g., "You are at the {receptacle}" or the receptacle is now in the observable list).
## Instructions
1. Identify the target receptacle from the goal or current observation.
2. Execute the `go to` action.
3. If the environment responds with "Nothing happened", the action was invalid. Consult the `references/common_receptacles.md` list and the latest observation to formulate a new `go to` target.
4. Upon successful navigation, proceed with the next skill in the plan (e.g., `alfworld-object-interactor`).
## Example
**Input:** `target_receptacle: fridge 1`
**Sequence:**
1. `go to fridge 1` → Observation: "You are at fridge 1. On the fridge 1, you see nothing."
**Output:** Agent has arrived at fridge 1 and can now interact with it (open, take items, cool objects, etc.).
## Error Handling
- **Invalid Target:** If "Nothing happened" is observed, the receptacle may be unreachable or incorrectly named. Re-analyze the scene description to find a valid path or alternative receptacle.
- **Already at Location:** If the observation indicates you are already at the target, skip the `go to` action and proceed.

- 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.
