--- name: alfworld-locate-target-object description: Navigates 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. --- # Skill: Locate Target Object ## Purpose Use this skill when your goal requires a specific object and you need to find it. The skill directs you to a likely receptacle, inspects it, and confirms if the target is present. ## Core Workflow 1. **Identify Target & Suspected Location:** Determine the object you need and the most logical place to find it (e.g., food in the `fridge`, utensils in a `drawer`). 2. **Navigate:** Go to the suspected receptacle. 3. **Inspect:** If the receptacle is closed, open it. 4. **Locate:** Visually scan the contents for the target object. 5. **Report:** Output the object's location if found, or note its absence. ## Instructions Follow this sequence of actions and reasoning. **Thought:** I need to find a `<target_object>`. The most likely place for it is the `<suspected_receptacle>`. **Action:** `go to <suspected_receptacle>` **Observation:** *[You arrive at the receptacle. It may be open or closed.]* **Thought:** I am at the `<suspected_receptacle>`. To see inside, I must open it. **Action:** `open <suspected_receptacle>` **Observation:** *[The receptacle opens, revealing its contents.]* **Thought:** The `<suspected_receptacle>` is open. I will now look for the `<target_object>` among its contents. * **If the object is visible:** I have located the `<target_object>` in the `<suspected_receptacle>`. My location task is complete. * **If the object is not visible:** The `<target_object>` is not in the `<suspected_receptacle>`. I must consider the next most likely location. ## Key Principles * **Contextual Guessing:** Use common sense to guess the initial search location (e.g., `fridge` for perishables, `cabinet` for dry goods). * **Sequential Access:** You must `go to` a location before you can `open` it. * **Visual Confirmation:** Only trust the `Observation` after opening a receptacle to confirm an object's presence or absence. ## Example **Scenario:** You need to find a potato for a heating task. ``` Thought: I need to find a potato. Potatoes are commonly stored in the fridge. Action: go to fridge 1 Observation: The fridge 1 is closed. Action: open fridge 1 Observation: You open the fridge 1. The fridge 1 is open. In it, you see a potato 1, a lettuce 2. ``` **Result:** The potato has been located in `fridge 1`. You can now `take potato 1 from fridge 1` and proceed. ## Next Steps After successfully locating the object, you will typically need to `take` it or interact with it, which is outside the scope of this skill. If the object is not found, trigger this skill again with a new suspected location.

- 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-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.
