scienceworld-object-selector

# Skill: scienceworld-object-selector ## Purpose Identify and select the correct object from visible candidates in the ScienceWorld environment based on task-defined criteria (e.g., "non-living thing", "electrical component", "container"), then signal intent with a `focus on` action. ## When to Use - When a task requires choosing a specific type of object from multiple visible options - When the agent must classify objects by property (living/non-living, material type, function) to select one - When the task instructs finding and interacting with a particular category of object ## Workflow 1. **Survey the environment** -- Use `look around` to list all visible objects in the current location. 2. **Evaluate candidates** -- For each visible object, determine if it matches the task criteria. Exclude target containers (e.g., destination boxes) and fixed furniture from candidates. 3. **Select the best match** -- Choose the first suitable, portable object unless the task specifies a preference (e.g., "largest", "closest"). 4. **Signal intent** -- Execute `focus on [OBJECT]` to confirm selection. 5. **Execute the task action** -- Proceed with the required action (e.g., `pick up`, `move`, `use`). ## Examples ### Example 1: Find a non-living thing and move it **Task:** "Find a non-living thing. First, focus on the thing. Then, move it to the purple box." ``` > look around You see: purple box, table, battery, black wire, blue light bulb, red light bulb, red wire, switch, violet light bulb, yellow wire, ultra low temperature freezer. ``` **Evaluation:** Purple box is the destination. Table and freezer are fixed furniture. Remaining items (battery, wires, bulbs, switch) are all non-living and portable. ``` > focus on black wire You focus on the black wire. > move black wire to purple box You move the black wire to the purple box. ``` ### Example 2: Find an electrical component **Task:** "Find an electrical component and place it on the workbench." ``` > look around You see: workbench, chair, battery, glass cup, red wire, notebook. > focus on battery You focus on the battery. > move battery to workbench You move the battery to the workbench. ``` ## Key Principles - **Exclude destinations** -- Never select the target container or destination as the candidate object. - **Verify if uncertain** -- Use `examine [OBJECT]` for more detail about an object's properties before selecting. - **Task alignment** -- The selection should enable the next action in the task sequence.
