Places a held object onto or into a target receptacle. Trigger this skill when the agent is carrying an object and needs to deposit it at a specific location to complete a task, such as installing an item on a holder or storing it in a container. It takes the object and destination receptacle as inputs, performing a 'put' action to finalize the object's positioning according to the task goal.
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
1. **Verify Prerequisites**:
- Confirm you are currently holding the target object (`{obj}`).
- Confirm the target receptacle (`{recep}`) is present and accessible in the environment.
- If the receptacle is a container (e.g., cabinet, drawer), ensure it is open.
2. **Navigate to Receptacle**:
- Use the `go to {recep}` action to move to the target receptacle's location.
3. **Execute Placement**:
- Use the `put {obj} in/on {recep}` action to deposit the held object.
- The phrasing (`in` vs `on`) is determined by the receptacle type (e.g., `in` for containers, `on` for surfaces/holders). Use the trajectory as a reference.
4. **Handle Errors**:
- If the environment responds with "Nothing happened", the action was invalid. Consult the `references/action_guide.md` for troubleshooting common failure modes.Read the whole file at its exact version.
How to install
mdr add zjunlp/skillnet/alfworld-object-placer@sha256:b5df6087df4ce351The line at the top of this page pins the label git:20260307.388baa3, 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.
