alfworld-object-state-modifier skillA
alfworld-object-state-modifier is agent-read markdown (skill) from zjunlp/skillnet: Uses an appliance to change the state of an object (cooling, heating, or cleaning). Use when the task requires altering an object's temperature or cleanliness using a specific device (e.g., cooling with a fridge, heating with a microwave, cleaning with a sinkbasin). Takes the object, target state, and appliance as inputs and executes the corresponding modifier action..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Instructions
Change an object's state (cool, heat, or clean) using a household appliance. You must be holding the target object before executing the state change.
## Workflow
1. **Navigate to appliance:** `go to {appliance}` (e.g., `go to fridge 1`)
2. **Prepare if closed:** If observation says appliance is closed, execute `open {appliance}` -- verify it opens
3. **Execute state change:** `{action} {obj} with {appliance}` -- verify observation confirms the change
4. **Proceed:** Continue with the next task step (e.g., placing the modified object)
## Action Mapping
| State Change | Action | Typical Appliance |
|---|---|---|
| Cool | `cool {obj} with {appliance}` | `fridge 1` |
| Heat | `heat {obj} with {appliance}` | `microwave 1`, `stoveburner 1` |
| Clean | `clean {obj} with {appliance}` | `sinkbasin 1` |
## Error Recovery
- "Nothing happened": Check (1) you are holding the object, (2) appliance is open/ready, (3) object and appliance names are correct
- Appliance occupied: remove existing items first with `take {item} from {appliance}`
## Example
**Scenario:** You need to cool a tomato using the fridge.
