name: alfworld-search-pattern-executor
description: Systematically searches a sequence of likely locations for a target object based on common sense. Use when you need to find a specific object and know which receptacles to check but not which one contains it. Takes a list of candidate receptacles, orchestrates navigation and inspection, and outputs when the target is found or all locations are exhausted.
---
# Instructions
For each candidate receptacle in order, execute this action sequence:
## Workflow
1. **Navigate:** `go to {receptacle}`
2. **Open if closed:** If observation says "{receptacle} is closed", execute `open {receptacle}`
3. **Inspect:** Read the observation for the target object name
4. **If found:** Execute `take {target_object} from {receptacle}` and stop searching
5. **If not found:** If you opened the receptacle, execute `close {receptacle}`, then continue to the next candidate
6. **If all exhausted:** Report that the target was not found in any candidate location
## Action Format
- `go to {receptacle}` -- navigate to a location
- `open {receptacle}` -- open a closed drawer/cabinet/fridge
- `close {receptacle}` -- close after checking (state management)
- `take {object} from {receptacle}` -- pick up the target when found
## Key Rules
- Search candidates in order; do not skip locations
- Always close drawers/cabinets after checking if you opened them
- Once the object is found, immediately stop searching and proceed to the next task phase
- If "Nothing happened" is returned, verify the receptacle name and retry with the correct identifier
## Example
**Goal:** "find two remotecontrol and put them in armchair."
```
Thought: I need to find remotecontrol. Candidates: sofa 1, sidetable 1, coffeetable 1. Starting search.
Action: go to sofa 1
Observation: On the sofa 1, you see a pillow 1.
Thought: No remotecontrol on sofa 1. Checking next candidate.
Action: go to sidetable 1
Observation: On the sidetable 1, you see a keychain 1.
Thought: Not here either. Checking coffeetable.
Action: go to coffeetable 1
Observation: On the coffeetable 1, you see a remotecontrol 1, a remotecontrol 2.
Action: take remotecontrol 1 from coffeetable 1
Observation: You pick up the remotecontrol 1 from the coffeetable 1.
```
**Result:** First remotecontrol found and picked up. Proceed to place it in `armchair 1`, then re-activate search for the second one.

- 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.
