npx mdskill add zjunlp/SkillNet/scienceworld-tool-validatorValidate tools before critical use to prevent operational failure.
- Prevents measurement or connection errors by confirming instrument readiness.
- Depends on the focus on [TOOL] in inventory command and system response.
- Executes validation immediately after acquiring or switching to a new tool.
- Delivers a clear readiness confirmation or error message for the agent.

--- name: scienceworld-tool-validator description: 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. --- # 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.

- alfworld-appliance-navigatorNavigates the agent to a target appliance (microwave, stove, fridge, or sinkbasin) needed for object processing. Use when you are holding an object that needs heating, cooling, or cleaning and must move to the correct appliance station. Identifies the required appliance from the task context and executes the movement action.
- alfworld-appliance-preparerPrepares a household appliance (microwave, oven, toaster, fridge) for use by ensuring it is in the correct open/closed state. Use when the agent needs to heat, cool, or cook an item and must first open or close the appliance before placing an object inside. Takes an appliance identifier as input and outputs a confirmation that the appliance is ready for the next action.
- alfworld-clean-objectCleans a specified object using an appropriate cleaning receptacle (e.g., sinkbasin). Use when a task requires an object to be in a clean state (e.g., "clean potato", "wash apple") before proceeding. Navigates to the cleaning location, performs the clean action, and confirms the object is now clean.
- alfworld-device-operatorOperates a device or appliance (like a desklamp, microwave, or fridge) to interact with another object. Use when the task requires using a tool on a target item (e.g., "look at laptop under the desklamp", "heat potato with microwave"). Locates both the device and target object, co-locates them, and executes the appropriate use action (toggle, heat, cool, or clean).
- alfworld-environment-scannerPerforms an initial scan of the ALFWorld environment to identify all visible objects and receptacles. Use when you first enter an environment and need to build a mental map for task planning. Processes raw observation text into a structured list of entities, categorizing them as objects or receptacles.
- alfworld-goal-interpreterParses the natural language task goal to extract actionable sub-objectives and required objects. Trigger this skill whenever a new task is assigned to break down complex instructions into clear, sequential targets. It interprets phrases like 'look at X under Y' to identify target objects (pillow), reference objects (desklamp), and spatial relationships (under).
- alfworld-heat-object-with-applianceUses a heating appliance (microwave, stoveburner, oven) to apply heat to a specified object. Use when the task requires warming or cooking an item (e.g., "heat some egg", "warm the mug") and a heating appliance is available. Takes the object name and appliance name as input and outputs the object in a heated state, ready for placement at the task's target location.
- alfworld-inventory-managementUse when the agent must collect and track multiple instances of the same object type in ALFWorld (e.g., "put two cellphone in bed"). This skill maintains a count of collected versus needed objects, guides systematic searching through receptacles, and ensures each found object is placed at the target before searching for the next.
- alfworld-locate-target-objectNavigates to a suspected location and identifies a target object. Use when your goal requires finding a specific object (e.g., "potato", "plate") and its location is not immediately known. Moves to a relevant receptacle (like a fridge or cabinet), checks its contents, and outputs the object's location or confirms its absence.
- alfworld-location-navigatorMoves the agent to a specified receptacle or object location within the Alfworld environment. Use this skill when the agent needs to physically approach a target to inspect or interact with it, such as when checking an object's state or preparing for pickup. The skill takes a target location name as input and executes the 'go to' action, resulting in the agent being positioned at the destination for subsequent operations.
