- **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**
