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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 1. **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. 2. **Identify Target:** Determine the exact target object or location name (e.g., `ground`, `tree`, `metal fork`). 3. **Execute:** `use TOOL on TARGET`. 4. **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. 1. `pick up thermometer` — ensure tool is in inventory …

How to install
mdr add zjunlp/skillnet/scienceworld-tool-user@sha256:b0402aa357cc79bdThe line at the top of this page pins the label git:20260316.1c3faca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
