alfworld-object-picker skillA
alfworld-object-picker is agent-read markdown (skill) from zjunlp/skillnet: Picks up a specified object from a given receptacle. Use this skill when the agent has located a required object and needs to acquire it for later use, such as taking an item from a surface or container. The skill requires the object and source receptacle as inputs, executing a 'take' action to transfer the object into the agent's inventory, enabling further manipulation like placement or usage..
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
Execute the `take` action to acquire the target object from the source receptacle.
## Inputs
- `object`: The identifier of the object to pick up (e.g., "toiletpaper 1").
- `source_receptacle`: The identifier of the receptacle where the object is located (e.g., "toilet 1").
## Process
1. **Verify Context:** Ensure the agent is at the location of the `source_receptacle`. If not, the agent must navigate there first using a separate movement skill.
2. **Execute Action:** Perform the action: `take {object} from {source_receptacle}`.
3. **Handle Feedback:** If the environment indicates "Nothing happened," consult the troubleshooting guide in `references/troubleshooting.md` for potential issues.
## Output
- The specified object is transferred to the agent's inventory.
- The agent receives an observation confirming the successful pickup (e.g., "You pick up the {object} from the {source_receptacle}").
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
