Use when the agent is holding an object and needs to place it into a target receptacle in ALFWorld. This skill checks receptacle suitability, opens closed containers if needed, and executes the `put` command to store the object. It handles both open surfaces (countertops, beds) and closed containers (drawers, cabinets).
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
# Skill: Object Storer
## When to Use
Trigger this skill when:
1. The agent is holding the target object (optionally cleaned/heated/cooled as required)
2. A suitable storage receptacle has been identified
3. The agent needs to execute the final placement step
## Core Workflow
### 1. Validate Prerequisites
- Confirm the agent is holding `{object_name}` (check inventory)
- Confirm the agent is at the location of `{target_receptacle}`
- If not at the receptacle, navigate there first: `go to {target_receptacle}`
### 2. Check Receptacle State
Evaluate the receptacle before placing:
| Receptacle State | Action |
|-----------------|--------|
| Open and empty/suitable | Proceed with `put` |
| Closed (drawer, cabinet, safe) | `open {target_receptacle}` first, then `put` |
| Unsuitable (wrong type, full) | Abort and search for alternative receptacle |
### 3. Execute Storage
- Run: `put {object_name} in/on {target_receptacle}`
- Check the observation for confirmation
### 4. Verify Placement
- A successful placement updates the receptacle contents in the observation
- If the observation confirms the object is now in/on the receptacle, storage is complete

How to install
mdr add zjunlp/skillnet/alfworld-object-storer@sha256:b0892fe9588b3b3fThe 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.
