Scienceworld Tool User

Uses a tool from inventory on a target object or location to perform a specific environmental interaction, such as digging, cutting, or measuring. Use this skill when a task requires modifying the environment or manipulating materials with a tool (e.g., using a shovel to dig soil, a thermometer to measure temperature, or an axe to cut wood). Takes the tool and target as inputs and outputs the result of the interaction.

Skill: Tool User

Purpose

Perform a physical action on the environment using a tool from your inventory. The core action is use TOOL on TARGET.

When to Use

A task requires modifying the environment (digging, cutting, heating).
You need to measure a property of an object (temperature, conductivity).
A tool-based interaction is the next step in your experiment workflow.

Core Workflow

Ensure Tool in Inventory: The required tool (e.g., shovel, thermometer, axe) must be in your inventory. Use pick up OBJ if it is not.
Identify Target: Determine the exact target object or location name (e.g., ground, tree, metal fork).
Execute: use TOOL on TARGET.
Interpret Result: Read the observation output to determine the outcome (e.g., temperature reading, state change).

Key Actions

Action	Purpose
`pick up OBJ`	Acquire tool if not in inventory
`use OBJ on OBJ`	Perform tool interaction
`look around`	Confirm target identity and location

Example

Task: Measure the temperature of a metal fork using a thermometer.

pick up thermometer — ensure tool is in inventory
use thermometer on metal fork
Observation: "a thermometer, currently reading a temperature of 72 degrees celsius"

Important Notes

The tool must be in your inventory before use. The pick up action is a prerequisite.
Use exact object names as they appear in the environment description.
Some tools produce measurable outputs (thermometer readings); others produce state changes (shovel digs soil). Interpret accordingly.
