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
