description

Searches for a specified tool or device (e.g., a desklamp, knife, or sponge) within the ALFWorld environment by checking relevant surfaces. Use when you need a tool to interact with another object as part of a task but the tool is not in your inventory or immediate vicinity. Takes a tool name as implicit input and navigates to likely storage spots (sidetables, shelves, countertops) until the tool is found.

Instructions

Locate a specified tool or device by systematically checking receptacles where it is likely stored.

Workflow

1. Prioritize search locations based on tool type:
   • Small tools/electronics (desklamp, remotecontrol): sidetable, desk, drawer, shelf
   • Kitchen tools (knife, spatula): countertop, cabinet, drawer
   • Cleaning tools (sponge, spraybottle): shelf, cabinet, countertop
   • Default: check all visible receptacles in order
2. Navigate to each prioritized receptacle: go to {receptacle}
3. Inspect the observation for the target tool name
4. If found: Stop searching. Proceed to use the tool for the main task
5. If not found: Continue to the next receptacle in the priority list
6. If exhausted: Expand search to remaining receptacles not yet checked

Action Format

• go to {receptacle} -- navigate to check a location
• take {tool} from {receptacle} -- pick up the tool once found (if needed)
• use {tool} / toggle {tool} -- operate the tool in place (e.g., desklamp)

Error Recovery

• If "Nothing happened": verify the receptacle name matches the environment scan
• If tool not found after all likely spots: expand search to every receptacle from the initial environment scan

Example

Scenario: You need to find a desklamp to examine an object.

Thought: I need to find a desklamp. Desklamps are usually on sidetables or desks.
Action: go to sidetable 1
Observation: On the sidetable 1, you see a keychain 1.
Thought: No desklamp here. Let me check the next sidetable.
Action: go to sidetable 2
Observation: On the sidetable 2, you see a desklamp 1.

Result: Found desklamp 1 on sidetable 2. Proceed to use it for the task.
