| name | alfworld-receptacle-navigator |
| description | This skill plans and executes movement to a target receptacle within the environment. It should be triggered when the agent needs to interact with an object at a specific location (e.g., go to fridge to cool an item) or needs to access a receptacle itself (e.g., go to garbagecan to dispose of an item). The skill uses the receptacle name from the observation or task goal, outputs the 'go to' action, and confirms arrival at the destination. |
Skill: Receptacle Navigator
Purpose
Navigate to a specified receptacle (e.g., fridge 1, garbagecan 1, diningtable 1) in an ALFWorld household environment. This is a foundational skill for positioning the agent to perform subsequent object interactions.
When to Use
Trigger this skill when the agent's plan requires:
- Accessing a location to interact with an object there (e.g., "go to fridge to cool an item").
- Interacting with the receptacle itself (e.g., "go to garbagecan to dispose of an item").
Core Logic
- Input Parsing: Extract the target receptacle name (e.g.,
fridge 1) from the current task context or observation.
- Action Execution: Output the ALFWorld action:
go to {target_receptacle}.
- Success Verification: Confirm the action was successful by checking the observation for evidence of arrival (e.g., "You are at the {receptacle}" or the receptacle is now in the observable list).
Instructions
- Identify the target receptacle from the goal or current observation.
- Execute the
go to action.
- If the environment responds with "Nothing happened", the action was invalid. Consult the
references/common_receptacles.md list and the latest observation to formulate a new go to target.
- Upon successful navigation, proceed with the next skill in the plan (e.g.,
alfworld-object-interactor).
Error Handling
- Invalid Target: If "Nothing happened" is observed, the receptacle may be unreachable or incorrectly named. Re-analyze the scene description to find a valid path or alternative receptacle.
- Already at Location: If the observation indicates you are already at the target, skip the
go to action and proceed.
