Asreonn Godot Superpowers Godot Refactor

Godot Refactor Orchestrator

This orchestrator runs 5 code quality mini-skills in sequence. For individual operations, invoke mini-skills directly.

Core Principle: Scene-First, Signal-Based, Component Composition

Iron Law: NO functional or visual changes during refactoring. Period.

This skill automatically refactors Godot projects to cleaner, more modular architecture while preserving exact behavior. Every operation creates a git commit. Rollback is always available.

UPON INVOCATION - START HERE

When this skill is invoked, IMMEDIATELY execute the following sequence:

1. Verify Godot Project (5 seconds)

# Check if this is a Godot project
ls project.godot 2>/dev/null && echo "✓ Godot project detected" || echo "✗ Not a Godot project"

If NOT a Godot project:

• Inform user this skill only works on Godot projects
• Ask if they want to navigate to the correct directory
• STOP here

If IS a Godot project:

• Proceed to step 2

2. Begin Phase 1: Analysis & Baseline (AUTOMATIC)

Do NOT ask "What would you like me to do?" - Start analyzing immediately.

Execute these commands in parallel:

# Detect code-created objects
grep -rn "\.new()" --include="*.gd" . | grep -E "(Node|Timer|Area|Sprite|Control|Collision)" | wc -l

# Detect monolithic scripts
find . -name "*.gd" -exec wc -l {} + | awk '$1 > 150' | wc -l

# Detect tight coupling
grep -rn "get_node\|has_method" --include="*.gd" . | wc -l

# Detect inline data
grep -rn "^[[:space:]]*const.*\[" --include="*.gd" . | wc -l

3. Present Findings (30 seconds)

Show the user:

=== Godot Refactoring Analysis ===

Project: [project name from project.godot]

Anti-patterns detected:
- Code-created objects: X
- Monolithic scripts: X
- Tight coupling: X
- Inline data: X
- Conflicting operations: (will be detected after refactoring)

Total: X anti-patterns found

Refactoring includes:
✓ Automatic testing after each operation
✓ Auto-rollback on test failure
✓ Git commit per operation
✓ Push to remote on demand

Would you like me to:
1. Proceed with automatic refactoring (recommended)
2. Show detailed breakdown first
3. Cancel

4. Wait for User Choice

• If 1 (Proceed): Start Phase 2 immediately
• If 2 (Details): Show detailed file-by-file breakdown, then offer to proceed
• If 3 (Cancel): Exit skill

CRITICAL: Do NOT stop after loading the skill. Do NOT ask "What would you like me to do?" Start with step 1 immediately.

When to Use This Skill

Use this skill when you detect ANY of these symptoms:

Code-Created Objects:

• .new() calls in _ready(), _process(), or other lifecycle methods
• add_child() with programmatically created nodes
• Timers, Areas, Sprites created in code

Monolithic Scripts:

• Scripts >150 lines
• Multiple unrelated responsibilities in one file
• God objects that do everything

Tight Coupling:

• get_node() chains to access other nodes
• has_method() checks before calling
• Direct property access across nodes
• Parent-child dependencies for behavior

Inline Data:

• const arrays with game data
• Hardcoded configuration in scripts
• Data that should be resources

Deep Inheritance:

• More than 2 levels of script inheritance
• Inheritance used for code reuse instead of composition

The Four Phases

Phase 1: Analysis & Baseline (Automatic)

Purpose: Detect all anti-patterns and create safety baseline.

Steps:

1. Scan Project Files

# Find all Godot script files
find . -name "*.gd" -type f

# Find all scene files
find . -name "*.tscn" -type f

2. Detect Anti-Patterns

Use detection patterns from anti-patterns-detection.md:

# Code-created objects
grep -rn "\.new()" --include="*.gd" .

# Monolithic scripts (>150 lines)
find . -name "*.gd" -exec wc -l {} + | awk '$1 > 150 {print $2 " (" $1 " lines)"}'

# Tight coupling
grep -rn "get_node\|get_parent\|has_method" --include="*.gd" .

# Inline data
grep -rn "^[[:space:]]*const.*\[" --include="*.gd" .

3. Create Git Baseline

# Save current branch
current_branch=$(git branch --show-current)

# Create baseline tag
git tag baseline-$(date +%Y%m%d-%H%M%S)

# Initial commit if there are uncommitted changes
git add .
git commit -m "Baseline: Pre-refactoring state (on $current_branch)"

4. Generate Refactoring Manifest

Create a priority-ordered list:

Phase 1 Output:

• ✓ Baseline git commit/tag created
• ✓ Anti-patterns detected and prioritized
• ✓ Manifest table generated
• ✓ Ready for automatic refactoring

Phase 2: Automatic Refactoring (Five Operations)

Process anti-patterns in priority order: Data → Scenes → Signals → Scripts → Conflicts

CRITICAL - After Each Operation:

1. Git commit the changes
2. Run automatic validation test
3. If test fails: Auto-revert and report error
4. If test passes: Continue automatically to next operation
5. No user prompt unless test fails or user confirmation needed

Automatic Testing Procedure:

# Quick validation test (runs after each git commit)
echo "Running validation test..."
godot --headless --quit-after 5 project.godot 2>&1 | tee test_output.log

# Check for errors
if grep -q "ERROR\|SCRIPT ERROR\|Parse Error" test_output.log; then
    echo "⚠️  Tests failed - reverting operation"
    git reset --hard HEAD~1
    echo "❌ Operation reverted. Error details:"
    grep "ERROR\|SCRIPT ERROR\|Parse Error" test_output.log
    # STOP and report to user
else
    echo "✓ Tests passed - continuing"
    rm test_output.log
    # CONTINUE to next operation automatically
fi

Note: If test fails, STOP workflow and report to user. Otherwise, continue automatically through all operations.

Operation A: Extract Code-Created Objects to Modular Components

Target: Any .new() calls that create nodes

Enhanced Process:

1. Detect and Analyze

   • Find .new() calls for node types
   • Extract 30 lines of context (properties, methods, signals)
   • Analyze variable names, properties, methods
   • Consult node-selection-guide.md decision trees
   • Calculate confidence score for node type
   • Select optimal node from godot-node-reference.md

2. Check Component Library

   • Does components/{category}/ exist? (e.g., components/timers/)
   • If YES: Reuse base component, skip to Step 4
   • If NO: Generate full component structure (Steps 2-3)

3. Generate Component (First Time Only)

   • Create {type}_config.gd (Resource class with @export properties)
   • Create configurable_{type}.gd (Script that extends node, applies config)
   • Create configurable_{type}.tscn (Base scene with script)
   • Creates modular, reusable foundation

4. Generate Preset Resource

   • Extract properties from analyzed code
   • Create presets/{preset_name}.tres (specific configuration)
   • Each detected instance gets unique preset
   • Presets reference the base component

5. Update Parent Scene

   • Add ext_resource entries for base scene and preset
   • Instance base component with preset resource
   • Same scene reused, different presets = ZERO duplication

6. Update Parent Script

   • Add @onready reference to component instance
   • Keep signal connections
   • Remove .new(), add_child(), static property assignments
   • Configuration now comes from preset resource

7. Git Commit & Validate

   • Commit all component files and parent changes
   • Run validation test
   • Ensure behavior unchanged

Example Transformation:

Before (Code-Created):

func _ready():
    _damage_timer = Timer.new()
    _damage_timer.wait_time = 0.5
    _damage_timer.one_shot = false
    add_child(_damage_timer)
    _damage_timer.timeout.connect(_on_damage)

    _cooldown_timer = Timer.new()
    _cooldown_timer.wait_time = 2.0
    _cooldown_timer.one_shot = true
    add_child(_cooldown_timer)
    _cooldown_timer.timeout.connect(_on_cooldown)

After (First Timer - Full Component Created):

Files created:
✓ components/timers/timer_config.gd (resource class)
✓ components/timers/configurable_timer.gd (reusable script)
✓ components/timers/configurable_timer.tscn (reusable base scene)
✓ components/timers/presets/damage_timer.tres (configuration preset)

parent.gd:
@onready var _damage_timer: ConfigurableTimer = $DamageTimer

func _ready():
    _damage_timer.timeout.connect(_on_damage)

After (Second Timer - Reuses Base):

Files created:
✓ components/timers/presets/cooldown_timer.tres (NEW preset only!)

parent.gd:
@onready var _damage_timer: ConfigurableTimer = $DamageTimer
@onready var _cooldown_timer: ConfigurableTimer = $CooldownTimer

func _ready():
    _damage_timer.timeout.connect(_on_damage)
    _cooldown_timer.timeout.connect(_on_cooldown)

Key Benefits:

• ✅ Intelligent node selection (no arbitrary choices)
• ✅ Modular components (reusable across project)
• ✅ Zero duplication (same base, different presets)
• ✅ Inspector-configurable (edit presets in editor)
• ✅ Automatic library building (grows organically)
• ✅ Signal connections preserved
• ✅ Behavior unchanged (Iron Law maintained)

Success Criteria:

• Component structure created (if first of type)
• Preset resource created with extracted values
• Parent scene instances component with preset
• Parent script has @onready reference
• Signal connections work
• Old code removed
• Behavior unchanged

Operation B: Split Monolithic Scripts

Target: Scripts >150 lines with multiple responsibilities

Detection:

find . -name "*.gd" -exec wc -l {} + | awk '$1 > 150'

For each detected script:

1. Analyze script structure

   • Identify logical sections (look for comment headers, function groups)
   • Find responsibilities (input, physics, abilities, UI, etc.)
   • Determine dependencies between sections

2. Plan split

   • Main script keeps core responsibility
   • Extract secondary responsibilities to components
   • Define signal interface between components

3. Create component scripts

   Example: Split player_movement.gd (287 lines)

   Extract to player_abilities.gd:

   extends Node
   class_name PlayerAbilities
   
   signal ability_used(ability_name: String)
   signal cooldown_started(duration: float)
   
   # Ability-related functions moved here
   

4. Update main script

   @onready var abilities: PlayerAbilities = $Abilities
   
   func _ready():
       abilities.ability_used.connect(_on_ability_used)
   

5. Implement signal communication

   • Replace direct function calls with signals
   • Connect signals in _ready()
   • Remove tight coupling

6. Git commit

   git add player_movement.gd player_abilities.gd
   git commit -m "Refactor: Split abilities from player_movement.gd"
   

7. Run automatic test (see Phase 2 header for test procedure)

Success criteria:

• Main script <150 lines
• Component scripts focused (80-120 lines optimal)
• Signal-based communication
• No direct dependencies
• Behavior unchanged

Operation C: Implement Signal-Based Decoupling

Target: Direct coupling via get_node(), has_method(), direct calls

Detection:

grep -rn "get_node\|has_method" --include="*.gd" .

For each detected coupling:

1. Identify the relationship

   • What is being accessed?
   • What information is being exchanged?
   • Is this event-based or state query?

2. Create/use Events autoload

   If not exists, create events.gd:

   extends Node
   # Global event bus
   
   signal player_entered_safe_zone(zone: Node2D)
   signal enemy_spawned(enemy: Node2D)
   signal score_changed(new_score: int)
   

   Add to project settings: Project → Project Settings → Autoload

3. Replace direct coupling with signals

   Before:

   func _on_body_entered(body):
       if body.has_method("set_beam_enabled"):
           body.set_beam_enabled(false)
   

   After (emitter):

   func _on_body_entered(body):
       if body.is_in_group("player"):
           Events.player_entered_safe_zone.emit(self)
   

   After (receiver):

   func _ready():
       Events.player_entered_safe_zone.connect(_on_safe_zone)
   
   func _on_safe_zone(zone):
       set_beam_enabled(false)
   

4. Remove coupling code

   • Delete get_node() calls
   • Delete has_method() checks
   • Delete direct property access

5. Git commit

   git add events.gd base_station.gd player_movement.gd
   git commit -m "Refactor: Decouple base_station from player via signals"
   

6. Run automatic test (see Phase 2 header for test procedure)

Success criteria:

• No get_node() for behavior access
• No has_method() checks
• Events.gd exists and is used
• Signal connections established
• Behavior unchanged

Operation D: Extract Data to .tres Resources

Target: const declarations with game data

Detection:

grep -rn "^[[:space:]]*const.*\[" --include="*.gd" .

For each detected data constant:

1. Analyze data structure

   const ENEMY_TYPES = [
       {"type": "basic", "health": 100, "speed": 200},
       {"type": "fast", "health": 50, "speed": 400}
   ]
   

2. Create Resource class

   Create enemy_type_data.gd:

   extends Resource
   class_name EnemyTypeData
   
   @export var type_name: String
   @export var health: int
   @export var speed: float
   

3. Generate .tres files

   Create enemy_types/basic.tres:

   [gd_resource type="EnemyTypeData" load_steps=2 format=3]
   
   [ext_resource type="Script" path="res://enemy_type_data.gd" id="1"]
   
   [resource]
   script = ExtResource("1")
   type_name = "basic"
   health = 100
   speed = 200.0
   

4. Update script to use resources

   @export var enemy_types: Array[EnemyTypeData]
   
   # In scene, assign resources via inspector
   

5. Remove const declaration

6. Git commit

   git add enemy_type_data.gd enemy_types/*.tres enemy_spawner.gd
   git commit -m "Refactor: Extract enemy data to .tres resources"
   

7. Run automatic test (see Phase 2 header for test procedure)

Success criteria:

• Resource class created
• .tres files generated with correct data
• Script updated to use resources
• Const declaration removed
• Behavior unchanged

Operation E: Clean Conflicting/Ineffective Operations

Target: Code that runs without errors but has no effect or conflicts with other code

IMPORTANT: This operation runs after Operations A-D are complete, as refactoring may introduce or remove conflicts.

Detection:

# Run comprehensive conflict detection
bash << 'EOF'
echo "=== Detecting Conflicting Operations ==="

# Self-assignments
echo "Self-assignments:"
grep -rn "position\s*=\s*position\|scale\s*=\s*scale\|rotation\s*=\s*rotation" --include="*.gd" .

# Redundant defaults
echo "Redundant defaults:"
grep -rn "modulate\s*=\s*Color\.WHITE\|scale\s*=\s*Vector2\.ONE" --include="*.gd" .

# Duplicate property assignments (common properties)
echo "Checking for duplicate assignments..."
for prop in "scale" "position" "rotation" "modulate" "visible"; do
    grep -rn "\.$prop\s*=" --include="*.gd" . | \
    awk -F: -v prop="$prop" '{
        file=$1; line=$2;
        if (file==prev_file && line-prev_line<20) {
            print file":"prev_line" and "line" - Duplicate "prop
        }
        prev_file=file; prev_line=line
    }'
done

# Conflicting tweens
echo "Conflicting tweens:"
grep -n "tween_property" --include="*.gd" -r . | \
awk -F: '{
    file=$1; line=$2;
    if (match($0, /tween_property.*"([^"]+)"/, arr)) {
        prop=arr[1];
        key=file":"prop;
        if (key in seen && line-seen[key]<15) {
            print file":"seen[key]" and "line" - Conflicting tweens on "prop
        }
        seen[key]=line
    }
}'

# Code after queue_free
echo "Code after queue_free:"
grep -A2 "queue_free()" --include="*.gd" . | grep -v "^--$"

EOF

For each detected conflict:

1. Auto-fix (no user input):

   • Self-assignments: Remove entirely
   • Code after queue_free(): Move code before queue_free
   • Obvious redundant defaults: Remove

2. User confirmation (ask user):

   • Duplicate assignments: Which value to keep?
   • Conflicting tweens: Which to keep or chain?
   • Multiple process calls: Final intended state?

3. Example fixes:

   Self-assignment:

   # Before
   position = position
   
   # After (remove line)
   

   Duplicate assignment:

   # Before
   sprite.scale = Vector2(2, 2)  # Line 45
   sprite.scale = Vector2(1, 1)  # Line 52
   
   # After (keep last)
   sprite.scale = Vector2(1, 1)  # Line 52
   

   Conflicting tweens (user chose "chain"):

   # Before
   var tween1 = create_tween()
   tween1.tween_property(self, "scale", Vector2(2,2), 1.0)
   var tween2 = create_tween()
   tween2.tween_property(self, "scale", Vector2(0.5,0.5), 1.0)
   
   # After
   var tween = create_tween()
   tween.tween_property(self, "scale", Vector2(2,2), 1.0)
   tween.tween_property(self, "scale", Vector2(0.5,0.5), 1.0)
   

4. Git commit

   git add <modified files>
   git commit -m "Refactor: Clean conflicting/ineffective operations
   
   - Removed self-assignments
   - Fixed duplicate property assignments
   - Resolved conflicting tweens
   - Cleaned up redundant operations
   
   No functional changes - code cleanup only"
   

5. Run automatic test (see Phase 2 header for test procedure)

Success criteria:

• No self-assignments remain
• No obvious duplicate assignments
• Conflicting tweens resolved
• Code after queue_free() moved
• Behavior unchanged

Note: See conflicting-operations-detection.md for comprehensive detection patterns and refactoring-operations.md Operation E for detailed procedures.

Phase 3: Git Commits (Automatic)

After each operation, commit with clear message:

# Template
git add <files>
git commit -m "Refactor: <Operation> in <file> - <specific change>"

# Examples
git commit -m "Refactor: Extract Timer to scene in laser_beam.gd"
git commit -m "Refactor: Split abilities from player_movement.gd (287→142 lines)"
git commit -m "Refactor: Decouple base_station from player via signals"
git commit -m "Refactor: Extract enemy data to .tres resources"
git commit -m "Refactor: Clean conflicting/ineffective operations"

After all operations:

git tag refactor-complete-$(date +%Y%m%d)

Commit history should show:

• Baseline commit
• One commit per refactoring operation (A, B, C, D, E)
• Clear, descriptive messages
• Easy to review
• Easy to rollback individual changes

Push on Demand:

After all operations complete, ask user:

=== Refactoring Complete ===

All operations completed successfully!
5 operations performed, X commits created on current branch.

Would you like to push to remote?
1. Yes, push now
2. No, I'll push manually later
3. Show me the commit log first

Choice [1-3]:

If user chooses 1 (push now):

# Push to current branch's remote
git push origin $(git branch --show-current)

If user chooses 3 (show log first):

git log --oneline --graph baseline-*..HEAD
# Then ask again: Push now? [y/n]

If user says "push" or "push et" at ANY time during the workflow:

# Immediately push current branch
git push origin $(git branch --show-current)
echo "✓ Pushed to remote"

Phase 4: Final Verification (Minimal, Automatic)

Purpose: Ensure no functional or visual regressions.

Steps:

1. Open project in Godot

   godot --editor path/to/project.godot
   

2. Check for errors

   • No red errors in console
   • No yellow warnings about missing nodes
   • All scenes load successfully

3. Visual verification

   • Run main scene
   • Quick visual check (30 seconds)
   • Compare against expected behavior

4. Play test checklist (from verification-checklist.md):

   • Player movement works
   • Abilities trigger correctly
   • Enemies spawn and behave normally
   • UI updates properly
   • No crashes or errors

5. Performance baseline (optional):

   # Compare FPS before/after
   # Should be identical ±2 FPS
   

If verification fails:

# Rollback procedure
git reset --hard baseline-YYYYMMDD-HHMMSS
git tag refactor-failed-$(date +%Y%m%d-%H%M%S)

# Report what broke
# Debug with systematic-debugging skill

If verification succeeds:

Report summary:

✓ Refactoring complete
✓ 8 operations performed
✓ 287 lines reduced to 142 across 3 files
✓ 4 .tscn scenes created
✓ 2 .tres resources created
✓ Signal-based architecture established
✓ No functional changes
✓ All tests passing

Supporting Files

This skill uses modular reference files:

• anti-patterns-detection.md: All grep/find patterns for detection
• refactoring-operations.md: Detailed step-by-step procedures
• godot-best-practices.md: Clean patterns reference
• tscn-generation-guide.md: .tscn file format templates
• verification-checklist.md: Testing procedures

Read these files for detailed implementation guidance.

Red Flags - STOP

These thoughts mean you're rationalizing away discipline:

Quick Reference: Anti-Pattern → Clean Pattern

File Operation Flow

1. Data Extraction
   .gd with const → Resource class .gd + .tres files

2. Scene Extraction
   .gd with .new() → .gd with @onready + new .tscn

3. Signal Decoupling
   .gd with get_node() → events.gd + updated .gd files

4. Script Splitting
   Large .gd → Multiple focused .gd files with signals

Godot Naming Conventions

Scenes (.tscn):

• PascalCase for node names: DamageTimer, AbilitySystem
• snake_case for file names: damage_timer.tscn, ability_system.tscn

Scripts (.gd):

• snake_case for files: player_movement.gd, enemy_spawner.gd
• PascalCase for class_name: class_name PlayerMovement

Resources (.tres):

• snake_case for files: enemy_types/basic.tres
• PascalCase for Resource class: class_name EnemyTypeData

Signals:

• snake_case: signal ability_used, signal player_entered_safe_zone
• Past tense for events: signal enemy_spawned (not enemy_spawn)

@onready variables:

• snake_case with type hint: @onready var _damage_timer: Timer = $DamageTimer
• Private with underscore: _damage_timer, _ability_system

Common Mistakes

Signal Architecture Patterns

Event Bus (Events.gd):

# Use for global events
signal player_died
signal level_completed(level_num: int)
signal score_changed(new_score: int)

Direct Node Signals:

# Use for parent-child communication
signal health_depleted
signal ability_activated(ability_name: String)

When to use which:

• Events.gd: Cross-tree communication, global state changes
• Node signals: Parent-child, local behavior

Real-World Impact

Expected improvements after refactoring:

Code Quality:

• 30-50% reduction in total lines of code
• Scripts average 80-120 lines (down from 150-300)
• Zero direct node dependencies
• Signal-based architecture throughout

Maintainability:

• Changes isolated to single files
• Components reusable across scenes
• Testing individual components possible
• New developers onboard faster

Performance:

• Identical to baseline (±2 FPS)
• Scene loading slightly faster
• Memory usage unchanged

Execution Strategy

This skill runs fully automatically:

1. User invokes skill on Godot project
2. Phase 1: Scan and report findings
3. User approves refactoring
4. Phases 2-3: Execute all operations with commits on current branch
5. Phase 4: Verify and report results

User input required:

• Initial invocation
• Approval after Phase 1 analysis
• Final verification check (30 seconds)

Everything else is automatic:

• Anti-pattern detection
• .tscn file generation
• Script modifications
• Git commits on current branch
• Testing

Success Criteria

Refactoring is complete when:

• ✓ Zero .new() calls for scene nodes
• ✓ All scripts <150 lines
• ✓ Signal-based architecture established
• ✓ No get_node() for behavior access
• ✓ Data in .tres resources
• ✓ Clean git history with descriptive commits on current branch
• ✓ All scenes load without errors
• ✓ Behavior identical to baseline
• ✓ Visual appearance unchanged
• ✓ Performance within ±2 FPS

Post-Refactoring

After successful refactoring:

1. Continue development

   • Changes are already on current branch
   • Push to remote if not already pushed
   • Continue normal development workflow

2. Document architecture

   • Create architecture diagram
   • Document signal flows
   • List component responsibilities

3. Establish standards

   • Use this clean architecture as template
   • Apply patterns to new code
   • Prevent anti-pattern regression

4. Consider further improvements (separate tasks):

   • Add unit tests (use TDD skill)
   • Optimize performance (profile first)
   • Add new features (use brainstorming skill)

Remember: Refactoring changes HOW code works internally, not WHAT it does externally. The Iron Law is absolute.
