# 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 thermometer. ``` The thermometer is validated. Proceed with measurement: ``` > use thermometer on unknown substance B The thermometer measures a temperature of 42 degrees celsius. ``` ### Example 2: Validating a scale after teleporting to a new room ``` > teleport to workshop You teleport to the workshop. > pick up scale You pick up the scale. > focus on scale in inventory You focus on the scale. ``` The scale is validated and ready to weigh objects. ## Key Principles - **Timing** -- Validate immediately after acquisition, before any task-sensitive operation. - **Simplicity** -- The `focus on` action is the primary, lightweight validation method. Avoid unnecessary `examine` or `use` actions during the check. - **State awareness** -- Ensure containers are open and items are accessible before attempting to pick up tools. Use `teleport to` for efficient navigation.
