Moves a specified object from the environment or inventory into a target container based on a classification decision. Use this skill when a task requires sorting or storing an object in a specific location after an assessment (e.g., placing a conductive object in the blue box or a non-conductive object in the orange box).
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 Placer ## Purpose Move an object into the correct container based on a prior classification or assessment result. This is the final step in conditional sorting workflows. ## Core Workflow 1. **Confirm Assessment Result:** Know which container corresponds to which classification (e.g., "blue box" = conductive, "orange box" = non-conductive). 2. **Acquire Object (if needed):** `pick up OBJ` if the target is not already in inventory. 3. **Execute Placement:** `move OBJ to OBJ` — place the object in the correct container. 4. **Verify Placement:** `look at <CONTAINER>` to confirm the object is now inside. ## Key Actions | Action | Purpose | |--------|---------| | `pick up OBJ` | Acquire object if not in inventory | | `move OBJ to OBJ` | Place object into destination container | | `look at OBJ` | Verify placement succeeded | ## Example **Task:** "Determine if metal pot is electrically conductive. If conductive, place in the blue box. If nonconductive, place in the orange box." 1. Assessment complete: circuit test confirmed metal pot is conductive. 2. `pick up metal pot` (if not already held) 3. `move metal pot to blue box` …

How to install
mdr add zjunlp/skillnet/scienceworld-object-placer@sha256:69148edc9d075272The line at the top of this page pins the label git:20260316.1c3faca, 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.
