alfworld-object-locator skillA
alfworld-object-locator is agent-read markdown (skill) from zjunlp/skillnet: 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..
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
# 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 | …
