+# AI Folder Files Analysis
+## Which Files Are Actually Needed for 3 Active Functions
+
+### ✅ **REQUIRED FILES** (All needed for active functions)
+
+#### 1. **tasks.py** - ✅ REQUIRED
+- **Purpose:** Unified Celery task entrypoint
+- **Used by:** All views (planner/views.py, writer/views.py)
+- **Dependencies:** engine.py, registry.py
+- **Status:** KEEP
+
+#### 2. **engine.py** - ✅ REQUIRED
+- **Purpose:** Central orchestrator for all AI functions
+- **Used by:** tasks.py
+- **Dependencies:** base.py, tracker.py, ai_core.py, settings.py, models.py
+- **Status:** KEEP
+
+#### 3. **base.py** - ✅ REQUIRED
+- **Purpose:** Abstract base class for all AI functions
+- **Used by:** All function classes (AutoClusterFunction, GenerateIdeasFunction, GenerateContentFunction)
+- **Dependencies:** None
+- **Status:** KEEP
+
+#### 4. **registry.py** - ✅ REQUIRED
+- **Purpose:** Function registry with lazy loading
+- **Used by:** tasks.py
+- **Dependencies:** base.py, function modules
+- **Status:** KEEP
+
+#### 5. **ai_core.py** - ✅ REQUIRED
+- **Purpose:** Centralized AI request handler
+- **Used by:** engine.py, all function classes
+- **Dependencies:** constants.py, tracker.py
+- **Status:** KEEP
+
+#### 6. **prompts.py** - ✅ REQUIRED
+- **Purpose:** Centralized prompt management
+- **Used by:** All function classes (build_prompt methods)
+- **Dependencies:** None
+- **Status:** KEEP
+
+#### 7. **settings.py** - ✅ REQUIRED
+- **Purpose:** Model configurations per function
+- **Used by:** engine.py
+- **Dependencies:** constants.py (via ai_processor import)
+- **Status:** KEEP
+
+#### 8. **validators.py** - ✅ REQUIRED
+- **Purpose:** Validation functions
+- **Used by:** All function classes (validate methods)
+- **Dependencies:** constants.py, models
+- **Status:** KEEP
+
+#### 9. **tracker.py** - ✅ REQUIRED
+- **Purpose:** Progress tracking utilities
+- **Used by:** engine.py, ai_core.py
+- **Dependencies:** types.py (imported but NOT USED), constants.py
+- **Status:** KEEP (but can remove types.py import)
+
+#### 10. **constants.py** - ✅ REQUIRED
+- **Purpose:** AI constants (model rates, valid models)
+- **Used by:** ai_core.py, settings.py, validators.py
+- **Dependencies:** None
+- **Status:** KEEP
+
+#### 11. **models.py** - ✅ REQUIRED
+- **Purpose:** AITaskLog database model
+- **Used by:** engine.py (for logging), admin.py
+- **Dependencies:** AccountBaseModel
+- **Status:** KEEP
+
+#### 12. **apps.py** - ✅ REQUIRED
+- **Purpose:** Django app configuration
+- **Used by:** Django (app registration)
+- **Dependencies:** admin.py
+- **Status:** KEEP
+
+#### 13. **admin.py** - ✅ REQUIRED (Optional but recommended)
+- **Purpose:** Django admin interface for AITaskLog
+- **Used by:** apps.py (auto-imported)
+- **Dependencies:** models.py
+- **Status:** KEEP (useful for debugging/admin)
+
+---
+
+### ❌ **UNUSED FILES** (Can be removed)
+
+#### 1. **types.py** - ❌ NOT USED
+- **Purpose:** Type definitions (StepLog, ProgressState, AITaskResult dataclasses)
+- **Used by:** tracker.py (imported but never instantiated)
+- **Actual usage:** None - tracker.py uses plain Dict types instead
+- **Status:** **SAFE TO REMOVE**
+- **Action:** Remove file and remove import from tracker.py
+
+---
+
+## Summary
+
+### Files to KEEP (13 files):
+1. ✅ tasks.py
+2. ✅ engine.py
+3. ✅ base.py
+4. ✅ registry.py
+5. ✅ ai_core.py
+6. ✅ prompts.py
+7. ✅ settings.py
+8. ✅ validators.py
+9. ✅ tracker.py
+10. ✅ constants.py
+11. ✅ models.py
+12. ✅ apps.py
+13. ✅ admin.py
+
+### Files to REMOVE (1 file):
+1. ❌ **types.py** - Imported but never used
+
+---
+
+## Action Items
+
+1. **Remove types.py** - File is not used
+2. **Remove import from tracker.py** - Remove `from igny8_core.ai.types import StepLog, ProgressState` (line 8)
+
+---
+
+## Verification
+
+All other files are actively used in the execution flow:
+- **tasks.py** → **registry.py** → **engine.py** → **base.py** (function classes)
+- **engine.py** → **ai_core.py** → **constants.py**
+- **engine.py** → **tracker.py** → **constants.py**
+- **engine.py** → **settings.py** → **constants.py**
+- **engine.py** → **models.py** (AITaskLog)
+- **function classes** → **prompts.py**, **validators.py**
+- **apps.py** → **admin.py** → **models.py**
