Use when the agent needs to find a specific object in ALFWorld that is not currently in inventory and whose location is unknown. This skill parses the environment observation, ranks receptacles by likelihood of containing the target object using common-sense reasoning, and outputs a navigation action to the most promising location.
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 Locator for ALFWorld ## When to Use Trigger this skill when: 1. Your goal requires a specific object (e.g., `knife`, `cellphone`, `apple`) 2. The object is not in your inventory 3. The current observation does not explicitly state the object's location ## Core Workflow ### 1. Parse the Environment Extract all visible receptacles from the observation text. Typical ALFWorld receptacles include: - **Surfaces**: countertop, desk, dresser, bed, shelf, sidetable, coffeetable, diningtable - **Containers**: drawer, cabinet, safe, fridge, microwave, garbagecan - **Appliances**: sinkbasin, bathtub, stoveburner, toaster ### 2. Rank by Likelihood Use common-sense reasoning to prioritize where the target object is most likely found: | Object Type | High-Probability Receptacles | |-------------|------------------------------| | Kitchen items (knife, spatula, pan) | countertop, drawer, diningtable, stoveburner | | Food (apple, potato, tomato, bread) | fridge, countertop, diningtable, microwave | | Bathroom items (sponge, cloth, soap) | sinkbasin, bathtub, cart, shelf | | Electronics (cellphone, laptop, remote) | desk, sidetable, dresser, bed, coffeetable | …

How to install
mdr add zjunlp/skillnet/alfworld-object-locator@sha256:2c70aec1ee83e4e6The 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.
