# Skill: Target Object Identifier ## Purpose This skill enables you to systematically locate objects in the ScienceWorld environment that match a specific target description (e.g., "living thing", "container", "electrical device"). It transforms the raw observation text from `look around` into a structured list of candidate objects for your current task. ## When to Use 1. **Trigger Condition**: Immediately after executing `look around` in any room. 2. **Input Required**: The full observation text from `look around` AND the target description from your task. 3. **Output**: A prioritized list of matching objects with their locations and properties. ## Execution Workflow ### Step 1: Parse Observation Extract all observable items from the room description. Pay special attention to: - Objects listed after "Here you see:" - Objects in containers (marked with "containing" or "On the X is:") - Substances (marked as "a substance called") - Living vs. non-living distinctions ### Step 2: Apply Target Filter Use the bundled classification script to filter objects based on the target description: - For "living thing": Include animals, plants, eggs, and biological organisms - For specific categories: Match against known object taxonomies - For generic descriptions: Use semantic similarity matching ### Step 3: Prioritize Candidates Rank candidates by: 1. **Accessibility**: Objects not in closed containers first 2. **Proximity**: Objects in current room before other locations 3. **Task Relevance**: Objects matching secondary task criteria (e.g., "easy to transport") ### Step 4: Generate Action Plan For each high-priority candidate: 1. Note its exact name as it appears in observations 2. Determine if `pick up`, `focus on`, or other preliminary action is needed 3. Plan path to target location if specified in task ## Key Considerations - **Exact Object Names**: Use the exact phrasing from observations (e.g., "turtle egg" not "egg turtle") - **Container States**: All containers are open per environment rules - **Teleportation**: You can instantly move between rooms when searching - **Multiple Matches**: If multiple objects match, select based on task context (e.g., choose less mobile items for transport tasks) ## Error Handling - If no matches found: Teleport to another room and repeat - If ambiguous matches: Use `examine OBJ` for clarification - If classification uncertain: Check reference taxonomy in bundled resources ## Example Application *Task*: "Find a living thing and move it to the blue box in bathroom" 1. `look around` in current room 2. Run this skill with target="living thing" 3. Receive list: ["baby wolf", "turtle egg", "crocodile egg"] 4. Select "turtle egg" (easier to transport) 5. `focus on turtle egg` → `pick up turtle egg` → `teleport to bathroom` → `move turtle egg to blue box`
