Use when the agent has acquired a tool or instrument and needs to verify it is operational before first use in a critical task step. This skill performs a lightweight pre-use check via "focus on [TOOL] in inventory" and confirms readiness based on the system's response, ensuring the tool is functional before measurement, activation, or connection operations.
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: scienceworld-tool-validator ## Purpose Perform a pre-use functionality check on a tool or instrument to confirm it is operational before employing it in a critical ScienceWorld task step such as measurement, activation, or connection. ## When to Use - Immediately after acquiring a tool (e.g., `pick up thermometer`) and before its first use - When switching to a different tool mid-task and needing to confirm readiness - When resuming a task after navigation and needing to re-confirm tool availability ## Workflow 1. **Acquire the tool** -- Ensure the target tool is in inventory. If not, locate it with `look around` and retrieve it with `pick up [TOOL]`. 2. **Execute validation** -- Run: `focus on [TOOL] in inventory`. 3. **Confirm readiness** -- A successful response (`"You focus on the [TOOL]."`) confirms the tool is operational. No further diagnostic steps are needed unless an error is observed. 4. **Proceed** -- Use the validated tool in the task operation (e.g., `use thermometer on [TARGET]`). ## Examples ### Example 1: Validating a thermometer before measurement ``` > pick up thermometer You pick up the thermometer. > focus on thermometer in inventory …

How to install
mdr add zjunlp/skillnet/scienceworld-tool-validator@sha256:4ce596140b4de567The line at the top of this page pins the label git:20260316.e08426e, 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.
