• Maintainability: Low
• Testability: Low
• Reusability: Low

Target State

• File Sizes: 100-1200 lines each
• Module Count: 12 focused modules
• Methods: 5-10 per module
• Maintainability: High

🎓 Learning Resources

Understanding the Tool

# View tool source code
cat scripts/extract_lockpicking_methods.py

# Test tool on a subset
python3 scripts/extract_lockpicking_methods.py \
  --methods "shuffleArray" \
  --output-file "test.js" \
  --show-dependencies

Understanding the Architecture

1. Open lockpicking-game-phaser.js
2. Find method: createPins()
3. Note dependencies it calls
4. Compare with Pin System module extraction plan
5. See how methods group logically

Understanding the Game Flow

1. Open scenario_select.html
2. Launch a lockpicking scenario
3. Observe: Load → Init → Create Graphics → Ready for input
4. Compare with EXTRACTION_GUIDE.md workflow diagram

🐛 Troubleshooting Guide

"Module not found" Error

Error in browser console: "Cannot find module './lock-configuration.js'"

Solution: Verify file was created and path is correct in import statement

"Game breaks after extraction"

ReferenceError: createPins is not defined

Solution: You removed the method but didn't update the call. Either re-add the method or update the call to use the module.

"Extraction tool says method not found"

❌ Method 'createLockBackground' not found

Solution: Check spelling (case-sensitive) and method exists in source file

"Don't understand dependencies warning"

⚠️  Dependencies: updatePinVisuals, this.scene.add.graphics()

Solution: This is informational. You don't need to do anything. The tool just tells you what the extracted methods call.

"Want to undo an extraction"

# Option 1: Delete the file
rm js/minigames/lockpicking/lock-configuration.js

# Option 2: Revert all changes
git checkout -- .

1. Extract methods using the tool
2. Update imports in the main class
3. Test the game
4. Commit your changes
5. Repeat

Estimated time: 1-2 weeks of development with testing
Difficulty: Medium (high reward, manageable risk)
