scienceworld-tool-validator
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.

Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 You focus on the t

How do I install it?
Run `npx skills add zjunlp/SkillNet --skill scienceworld-tool-validator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From zjunlp/SkillNet, a repository with 1,117 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
