Instructions

Trigger Condition: Use this skill when an initial search for a target object (e.g., cellphone) has been performed but the required quantity has not been found, or when you need to verify that no viable location was missed before task failure.

Core Procedure

1. Initialize Tracking: Maintain a mental or explicit list of all receptacles (recep) you have already visited during your initial search (e.g., sidetable 1, shelf 1-8, drawer 1, drawer 2, desk 1).

2. Systematic Revisit: Do not search new, unvisited locations. Instead, systematically return to each previously visited receptacle in a logical order (e.g., by proximity or by the original search sequence).

   • Action: Use go to {recep} to navigate.
   • For Closed Receptacles: If a receptacle was closed during the initial search and you opened it, it may be closed again. Re-open it to verify its contents.
     • Action: Use open {recep}.
   • For Open/Empty Receptacles: Observe the contents again. The state may have changed, or an item may have been overlooked.
   • Action: No action needed; read the Observation.

3. Verification Logic: For each revisited location:

   • If the target object is now present, retrieve it (take {obj} from {recep}) and proceed with the main task.
   • If the location is confirmed to lack the target object, note it as thoroughly checked and move to the next location on your list.
   • If you encounter a closed receptacle you previously assumed was empty, opening it is a critical verification step.

4. Conclusion: After revisiting all locations on your list:

   • If the target object was found: Integrate it into your main task plan.
   • If the target object was not found: You can conclusively report that the object is not available in the searched area and adjust your task strategy accordingly (e.g., consider task failure or exploring a new, unsearched area).

Example

Scenario: You need two cellphones but only found one. Revisiting previously searched locations.

Thought: I only found 1 cellphone but need 2. Let me revisit sidetable 1 which I checked earlier.
Action: go to sidetable 1
Observation: On the sidetable 1, you see a cellphone 2, a keychain 1.
Thought: Found cellphone 2! I must have overlooked it during the initial search.
Action: take cellphone 2 from sidetable 1
Observation: You pick up the cellphone 2 from the sidetable 1.

Result: The second cellphone was found by re-examining a previously visited location.
