| 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
- Navigate:
go to {receptacle}
- Open if closed: If observation says "{receptacle} is closed", execute
open {receptacle}
- Inspect: Read the observation for the target object name
- If found: Execute
take {target_object} from {receptacle} and stop searching
- If not found: If you opened the receptacle, execute
close {receptacle}, then continue to the next candidate
- 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
