name: alfworld-object-storer
description: Use when the agent is holding an object and needs to place it into a target receptacle in ALFWorld. This skill checks receptacle suitability, opens closed containers if needed, and executes the `put` command to store the object. It handles both open surfaces (countertops, beds) and closed containers (drawers, cabinets).

# Skill: Object Storer
## When to Use
Trigger this skill when:
1. The agent is holding the target object (optionally cleaned/heated/cooled as required)
2. A suitable storage receptacle has been identified
3. The agent needs to execute the final placement step
## Core Workflow
### 1. Validate Prerequisites
- Confirm the agent is holding `{object_name}` (check inventory)
- Confirm the agent is at the location of `{target_receptacle}`
- If not at the receptacle, navigate there first: `go to {target_receptacle}`
### 2. Check Receptacle State
Evaluate the receptacle before placing:
| Receptacle State | Action |
|-----------------|--------|
| Open and empty/suitable | Proceed with `put` |
| Closed (drawer, cabinet, safe) | `open {target_receptacle}` first, then `put` |
| Unsuitable (wrong type, full) | Abort and search for alternative receptacle |
### 3. Execute Storage
- Run: `put {object_name} in/on {target_receptacle}`
- Check the observation for confirmation
### 4. Verify Placement
- A successful placement updates the receptacle contents in the observation
- If the observation confirms the object is now in/on the receptacle, storage is complete
## Example
**Task:** "Clean the knife and put it in a drawer."
```
> go to drawer 1
The drawer 1 is closed.
> open drawer 1
You open the drawer 1. The drawer 1 is open. In it, you see nothing.
> put knife 1 in/on drawer 1
You put the knife 1 in/on the drawer 1.
```
**Result:** `knife 1` is now stored in `drawer 1`. Task complete.
**Example 2 — Open surface:**
```
> go to bed 1
On the bed 1, you see a pillow 1.
> put cellphone 2 in/on bed 1
You put the cellphone 2 in/on the bed 1.
```
## Error Handling
- **"Nothing happened"**: The agent may not be holding the object, or the receptacle name is incorrect. Verify with `inventory` and re-check the receptacle identifier.
- **Receptacle unsuitable**: If the receptacle is not appropriate for the object, search for an alternative using the object-locator skill.
- **Agent not at receptacle**: Navigate to the receptacle with `go to {target_receptacle}` before attempting `put`.
More from zjunlp/SkillNet
- 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.
