Skill: Object Focuser

Purpose

Use this skill to formally select a target object in the ScienceWorld environment. The focus on action signals your intent to the task system and is often a prerequisite for subsequent manipulation steps like pick up or move.

When to Use

• After you have identified an object that matches the task's criteria (e.g., "a living thing", "a conductive material").
• Before you attempt to pick up, move, or use that object as part of the task sequence.
• When the task trajectory or environment feedback suggests an object needs to be "focused on" to proceed.

Core Instruction

1. Identify the Target: From your observation (look around, examine), determine the exact name of the object you intend to use for the task.
2. Execute Focus: Use the action: focus on <OBJECT_NAME>.
   • Replace <OBJECT_NAME> with the precise noun phrase from the environment (e.g., dove egg, copper wire, beaker).
3. Proceed: After receiving a confirmation observation, continue with the next step in your plan (e.g., pick up <OBJECT_NAME>, move <OBJECT_NAME> to ...).

Key Considerations

• Object Naming: Use the name exactly as it appears in observations. The system is case-sensitive and expects the full descriptor (e.g., "dove egg", not just "dove" or "egg").
• Timing: Focus is typically performed after exploration/identification and before the main manipulation action.
• Task Logic: This action is a procedural formality within ScienceWorld. It does not change the object's state but informs the task tracker of your selected target.

Example

Task: Focus on a dove egg before picking it up for a biology task.

1. look around — observe: "a dove egg on the table"
2. focus on dove egg
3. Confirmation received → proceed with pick up dove egg.
