## Description

Use when the agent needs to find a specific object in ALFWorld that is not currently in inventory and whose location is unknown. This skill parses the environment observation, ranks receptacles by likelihood of containing the target object using common-sense reasoning, and outputs a navigation action to the most promising location.

# Skill: Object Locator for ALFWorld

## When to Use
Trigger this skill when:
1. Your goal requires a specific object (e.g., `knife`, `cellphone`, `apple`)
2. The object is not in your inventory
3. The current observation does not explicitly state the object's location

## Core Workflow

### 1. Parse the Environment
Extract all visible receptacles from the observation text. Typical ALFWorld receptacles include:
- **Surfaces**: countertop, desk, dresser, bed, shelf, sidetable, coffeetable, diningtable
- **Containers**: drawer, cabinet, safe, fridge, microwave, garbagecan
- **Appliances**: sinkbasin, bathtub, stoveburner, toaster

### 2. Rank by Likelihood
Use common-sense reasoning to prioritize where the target object is most likely found:

| Object Type | High-Probability Receptacles |
|-------------|------------------------------|
| Kitchen items (knife, spatula, pan) | countertop, drawer, diningtable, stoveburner |
| Food (apple, potato, tomato, bread) | fridge, countertop, diningtable, microwave |
| Bathroom items (sponge, cloth, soap) | sinkbasin, bathtub, cart, shelf |
| Electronics (cellphone, laptop, remote) | desk, sidetable, dresser, bed, coffeetable |
| Stationery (pen, pencil, book) | desk, shelf, drawer, sidetable |
| Lighting (candle, desklamp) | sidetable, shelf, desk, dresser |

### 3. Navigate and Search
For each candidate receptacle (in priority order):
1. `go to {receptacle}`
2. Read the observation, does it mention the target object?
   - **YES**: `take {object} from {receptacle}`, object found
   - **NO**: If the receptacle is closed, `open {receptacle}` and re-check
   - **Still NO**: Move to the next candidate receptacle

### 4. Track Searched Locations
Maintain a list of already-searched receptacles to avoid revisiting them. If all high-probability locations are exhausted, expand the search to remaining receptacles.
