Scienceworld Task Parser

3. Identify the Target Object

• From the room description, identify objects matching the parsed Target Object Type.
• If multiple candidates exist, select one that is clearly non-living, portable, and not part of a fixed apparatus (e.g., a wire, a light bulb, a battery). Avoid substances like 'air'.
• Use examine OBJ or look at OBJ if you need more detail to confirm an object's properties.

4. Execute the Task Sequence

1. Signal Intent: Use focus on OBJ on the identified target object. This explicitly marks the object for the task.
2. Perform Core Action: Execute the primary action from the parsed instruction (e.g., move OBJ to OBJ, pour OBJ into OBJ).
3. Use wait or wait1 only if necessary to allow for state changes.

Key Principles

• Efficiency: All containers are pre-opened. Do not use open or close unless explicitly required.
• Directness: Teleport directly to the target room. Do not explore unrelated rooms.
• Clarity: Structure your internal reasoning using the "Thought:" prefix before each action, as shown in the trajectory.
• Verification: If an initial look around is insufficient, a second look around is acceptable to confirm the environment state before proceeding.

Example

Task instruction: "Find a non-living thing in the workshop and move it to the purple box."

1. Parse: Target = non-living object, Location = workshop, Container = purple box.
2. teleport to workshop
3. look around — observe: "a battery, a blue light bulb, an orange wire..."
4. Select: battery (non-living, portable).
5. focus on battery
6. move battery to purple box
