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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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.

How to install

The exact contents, by fingerprint
mdr add zjunlp/skillnet/alfworld-object-state-modifier@sha256:693940a294589a86

The line at the top of this page pins the label git:20260316.e08426e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
