--- name: alfworld-receptacle-navigator description: Plans and executes movement to a target receptacle within the ALFWorld environment. Use when the agent needs to reach a specific location before interacting with objects there (e.g., go to fridge to cool an item, go to garbagecan to dispose of an item). Takes a receptacle identifier as input, executes the `go to` action, and outputs confirmation of 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: 1. **Accessing a location** to interact with an object there (e.g., "go to fridge to cool an item"). 2. **Interacting with the receptacle itself** (e.g., "go to garbagecan to dispose of an item"). ## Core Logic 1. **Input Parsing:** Extract the target receptacle name (e.g., `fridge 1`) from the current task context or observation. 2. **Action Execution:** Output the ALFWorld action: `go to {target_receptacle}`. 3. **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 1. Identify the target receptacle from the goal or current observation. 2. Execute the `go to` action. 3. 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. 4. Upon successful navigation, proceed with the next skill in the plan (e.g., `alfworld-object-interactor`). ## Example **Input:** `target_receptacle: fridge 1` **Sequence:** 1. `go to fridge 1` → Observation: "You are at fridge 1. On the fridge 1, you see nothing." **Output:** Agent has arrived at fridge 1 and can now interact with it (open, take items, cool objects, etc.). ## 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.
