Agent Building
View on GitHub

Inspects a receptacle's contents by navigating to it and reading the observation. Use when you need to check what is on or inside a receptacle (e.g., "what's on the shelf", "is the holder empty", "check the table for items"). Executes `go to {receptacle}`, parses the observation listing items present, and decides whether to take an item, search elsewhere, or proceed.

Instructions

Inspect the state or contents of a target receptacle by navigating to it and parsing the environment's observation feedback.

Workflow

  1. Navigate: Execute go to {target_receptacle}
  2. Read observation: The environment automatically reports what is on/in the receptacle -- no additional inspection action is needed
  3. Parse contents: Look for patterns:
    • "On the {receptacle}, you see nothing." -- receptacle is empty
    • "On the {receptacle}, you see a {item1}, and a {item2}." -- items are present
  4. Decide next action based on the observation:
    • Empty: search elsewhere for the needed item
    • Item found: take {item} from {receptacle}
    • Wrong items: move on to the next receptacle

Error Recovery

  • "Nothing happened": the go to target name is invalid -- verify the receptacle name from your environment scan
  • This skill uses only go to for navigation; it does not use open, close, or toggle

Example

Scenario 1: Check if a toiletpaperhanger has toilet paper.

Action: go to toiletpaperhanger 1
Observation: On the toiletpaperhanger 1, you see nothing.

Decision: Holder is empty. Find a toiletpaper roll elsewhere and bring it here.

Scenario 2: Check a toilet for available items.

Action: go to toilet 1
Observation: On the toilet 1, you see a soapbottle 1, and a toiletpaper 1.

Decision: toiletpaper 1 is available. Execute take toiletpaper 1 from toilet 1.
