Retrieve objects from environment into inventory for manipulation.

Enables testing, measuring, and transporting of physical items.
Depends on navigation tools to locate objects in rooms.
Executes pick up commands using exact object names.
Confirms success via inventory update feedback messages.

name: scienceworld-object-retriever
description: Acquires a specified object by moving it from the environment into the agent's inventory using 'pick up OBJ'. Use this skill when a task requires an object to be manipulated, tested, or transported and it is not yet in your inventory. Makes the object available for further actions like testing, measuring, or placing.

# Skill: Object Retriever

## Purpose
Acquire a target object from the environment and place it into your inventory for further use.

## When to Use
- You need an object for testing, measuring, or transporting.
- The object is visible in the room but not yet in your inventory.
- A downstream skill (e.g., tool-user, object-placer) requires the object in inventory.

## Core Workflow
1. **Navigate:** `teleport to LOC` if needed to reach the room containing the object.
2. **Survey:** `look around` to confirm the object is present and identify its exact name.
3. **Acquire:** `pick up OBJ` using the exact name from the environment description.
4. **Verify:** Check the observation feedback confirms "You move the [object] to the inventory."

## Example
**Task:** Retrieve a metal fork from the kitchen for conductivity testing.

1. `teleport to kitchen`
2. `look around` — see "a metal fork" on the counter
3. `pick up metal fork`
4. Observation: "You move the metal fork to the inventory."

## Important Notes
* Ensure you are in the correct room before attempting `pick up`. Use `teleport to LOC` if necessary.
* If `look around` does not reveal the object, use `examine` on containers or furniture (e.g., `examine table`).
* If a container is closed, use `open OBJ` first.
* After acquisition, the object is ready for the next skill in the task sequence.

Skill	Description
alfworld-appliance-navigator	Navigates 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-preparer	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.
alfworld-clean-object	Cleans 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-operator	Operates 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-scanner	Performs 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-interpreter	Parses 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-appliance	Uses 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-management	Use 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-object	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.
alfworld-location-navigator	Moves 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.
