Acquires a specified object by moving it from the environment into the agent's inventory using 'pick up OBJ'. Use this skill when a task requires an object to be manipulated, tested, or transported and it is not yet in your inventory. Makes the object available for further actions like testing, measuring, or placing.
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 Retriever ## Purpose Acquire a target object from the environment and place it into your inventory for further use. ## When to Use - You need an object for testing, measuring, or transporting. - The object is visible in the room but not yet in your inventory. - A downstream skill (e.g., tool-user, object-placer) requires the object in inventory. ## Core Workflow 1. **Navigate:** `teleport to LOC` if needed to reach the room containing the object. 2. **Survey:** `look around` to confirm the object is present and identify its exact name. 3. **Acquire:** `pick up OBJ` using the exact name from the environment description. 4. **Verify:** Check the observation feedback confirms "You move the [object] to the inventory." ## Example **Task:** Retrieve a metal fork from the kitchen for conductivity testing. 1. `teleport to kitchen` 2. `look around` — see "a metal fork" on the counter 3. `pick up metal fork` 4. Observation: "You move the metal fork to the inventory." ## Important Notes * Ensure you are in the correct room before attempting `pick up`. Use `teleport to LOC` if necessary. …

How to install
mdr add zjunlp/skillnet/scienceworld-object-retriever@sha256:ba38171ce15a44d4The 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.
