alfworld-object-state-inspector
Checks the current state or contents of a specified object or receptacle. Trigger this skill when the agent needs to determine if an object is present, missing, or in a certain condition before proceeding with a task, such as verifying if a holder is empty or if an item is available. It typically follows navigation and involves observing the environment's feedback, providing crucial information for decision-making in the task flow.

# Instructions Use this skill to inspect the state of a target object or receptacle in an AlfWorld household environment. The primary goal is to obtain the observation feedback from the environment about what is currently on or in the target. ## When to Trigger Trigger this skill immediately after navigating to a target receptacle (e.g., `go to toiletpaperhanger 1`) when you need to know: * If the target is empty. * What specific objects are present on/in the target. * The condition or state of the target (implied by the environment's observation). ## Core Procedure 1. **Navigate to Target:** First, ensure the agent has executed a `go to {target_receptacle}` action. This skill assumes the agent is already at the target's location. 2. **Observe Environment Feedback:** The skill is complete once the environment provides an observation in response to the navigation. **Do not perform an additional inspection action.** The observation from the `go to` action contains the state information. 3. **Parse Observation:** Interpret the observation message (e.g., "On the toiletpaperhanger 1, you see nothing." or "On the toilet 1, you see a soapbottle 1, and a toiletpaper 1."). 4. **Output Decis
