 # Changelog
 
+## [0.2.0] - 2025-09-30
+
+### 🚀 **Major Release: Folder-Based Prompts & Comprehensive Version Management**
+
+This is a **major architectural release** that fundamentally transforms how Promptix manages prompts, introducing a Git-native, folder-based structure and comprehensive version management system. This release enhances developer experience, improves Git integration, and provides professional version control for AI prompts.
+
+### 🎯 Breaking Changes
+
+#### **Folder-Based Prompt Storage**
+- **Migration from `prompts.yaml` to `prompts/` directory structure**
+- Each prompt now lives in its own folder with dedicated configuration and version history
+- **Migration is automatic** - existing `prompts.yaml` files are automatically migrated to the new structure
+- New structure provides:
+  - Better Git diffs (changes to individual files instead of large YAML)
+  - Clearer version history with dedicated version files
+  - Improved readability and organization
+  - Easier collaboration and code review
+
+**New Structure:**
+```
+prompts/
+├── CustomerSupport/
+│   ├── config.yaml          # Prompt metadata and configuration
+│   ├── current.md           # Current active version
+│   └── versions/
+│       ├── v1.md            # Version history
+│       ├── v2.md
+│       └── v3.md
+```
+
+**Old Structure (deprecated):**
+```
+prompts.yaml                 # All prompts in one file
+```
+
+### Added
+
+#### **Comprehensive Version Management System**
+- **Automatic Version Creation**: Pre-commit hooks automatically create new versions when `current.md` changes
+- **Version Switching**: Switch between different prompt versions with CLI or config
+- **Version Tracking**: `current_version` field in `config.yaml` tracks active version
+- **Version Header Removal**: Automatic removal of version metadata from prompt content
+- **Dual Support**: Backward compatibility with legacy `is_live` flags while supporting new `current_version` tracking
+
+#### **Enhanced CLI Tools**
+- **`promptix version` command group**:
+  - `promptix version list <agent>` - List all versions for an agent
+  - `promptix version create <agent>` - Manually create a new version
+  - `promptix version switch <agent> <version>` - Switch to a specific version
+  - `promptix version get <agent>` - Get current active version
+  
+- **`promptix hooks` command group**:
+  - `promptix hooks install` - Install pre-commit hook for automatic versioning
+  - `promptix hooks uninstall` - Remove pre-commit hook
+  - `promptix hooks status` - Check hook installation status
+  - Automatic backup/restore of existing hooks
+  - Safe hook installation with error handling
+
+#### **Git Pre-commit Hook**

-## 🌟 Why Promptix?
+</div>
 
-Managing prompts across multiple applications, models, and use cases can quickly become chaotic. Promptix brings order to this chaos:
+---
 
-- **No more prompt spaghetti** in your codebase
-- **Version and test prompts** with live/draft states
-- **Dynamically customize prompts** based on context variables
-- **Edit and manage** through a friendly UI with Promptix Studio
-- **Seamlessly integrate** with OpenAI, Anthropic, and other providers
+## 🎯 What is Promptix?
 
-## ✨ Key Features
+Stop hardcoding prompts in your Python code. **Promptix** is a powerful prompt management system that gives you **version control**, **dynamic templating**, and a **beautiful UI** for managing LLM prompts—all stored locally in your repository.
 
-### 🔄 Static Prompt Retrieval and Version Control
-Fetch your static prompts and manage different versions without dynamic templating:
+### 💡 Prompts Are Code
 
-```python
-# Get the latest live version of a static prompt
-live_prompt = Promptix.get_prompt("CustomerSupportStatic")
+In modern LLM applications, **your prompts are just as critical as your code**. A prompt change can alter your application's behavior, break functionality, or introduce bugs—just like a code change.
 
-# Test a new draft version in development
-draft_prompt = Promptix.get_prompt(
-    prompt_template="CustomerSupportStatic", 
-    version="v2"
-)
-```
+**Think about it:**
+- Your app's business logic lives in BOTH your Python code AND your prompts
+- A poorly tested prompt in production can cause customer-facing issues
+- You need to test the **combination** of code + prompts together
+- Rollback capabilities are essential when a prompt change goes wrong
+
+Yet most teams treat prompts as "just text"—no versioning, no testing, no staging environment.
+
+**Promptix brings software engineering rigor to prompts:**
+
+| Traditional Code | Prompts with Promptix |
+|------------------|----------------------|
+| ✅ Version control (Git) | ✅ Version control (built-in) |
+| ✅ Testing before deploy | ✅ Draft/Live states for testing |
+| ✅ Staging environment | ✅ Test versions in dev, promote to prod |
+| ✅ Rollback on issues | ✅ Revert to previous versions instantly |
+| ✅ Code review process | ✅ Visual diff and review in Studio |
+| ✅ CI/CD integration | ✅ File-based storage works with CI/CD |
+
+**Your prompts deserve the same engineering practices as your code.**
+
+> **Real-World Scenario:** Your customer support chatbot starts giving incorrect refund information. Was it a code bug or a prompt change? With prompts scattered in code, you can't easily tell. With Promptix, you see exactly which prompt version was live, can diff changes, and rollback instantly—just like you would with code.
 
-### 🎯 Dynamic Templating with Builder Pattern
-Create sophisticated, context-aware system instructions using the fluent builder API:
+### The Problem
 
 ```python
-# Generate a dynamic system instruction
-system_instruction = (
-    Promptix.builder("CustomerSupport")
-    .with_customer_name("Jane Doe")
-    .with_department("Technical Support")
-    .with_priority("high")
-    .with_tool("ticket_history")
-    .with_tool_parameter("ticket_history", "max_tickets", 5)
-    .system_instruction()  # Returns the system instruction string
-)
+# ❌ Before: Prompts scattered everywhere in your code
+def get_response(customer_name, issue):
+    system_msg = f"You are a helpful support agent. Customer: {customer_name}..."
+    # Copy-pasted prompts, no versioning, hard to maintain
 ```
 
-### 🤖 Model Configuration for API Calls
-Prepare complete configurations for different LLM providers:
+### The Solution
 
 ```python
-# OpenAI integration
-openai_config = (
-    Promptix.builder("AgentPrompt")
-    .with_customer_context(customer_data)
-    .with_issue_details(issue)
+# ✅ After: Clean, versioned, dynamic prompts
+from promptix import Promptix
+
+config = (
+    Promptix.builder("CustomerSupport")
+    .with_customer_name("Jane Doe")
+    .with_issue_type("billing")
     .for_client("openai")
     .build()
 )
-openai_response = openai_client.chat.completions.create(**openai_config)
 
-# Anthropic integration
-anthropic_config = (
-    Promptix.builder("AgentPrompt")
-    .with_customer_context(customer_data)
-    .with_issue_details(issue)
-    .for_client("anthropic")
-    .build()
-)
-anthropic_response = anthropic_client.messages.create(**anthropic_config)
+response = client.chat.completions.create(**config)
 ```
 
-### 🎨 Promptix Studio
-Manage prompts through a clean web interface by simply running:
+---
+
+## 🚀 Quick Start in 30 Seconds
 
+### 1. Install Promptix
 ```bash
-promptix studio
+pip install promptix
+```
+
+### 2. Create Your First Prompt
+```bash
+promptix studio  # Opens web UI at http://localhost:8501
 ```
 
-When you run this command, you'll get access to the Promptix Studio dashboard:
+This creates a clean, organized structure in your repository:
 
-![Promptix Studio Dashboard](https://raw.githubusercontent.com/Nisarg38/promptix-python/refs/heads/main/docs/images/promptix-studio-dashboard.png)
+```
+prompts/
+├── CustomerSupport/
+│   ├── config.yaml          # Prompt metadata and settings
+│   ├── current.md           # Current live version
+│   └── versions/
+│       ├── v1.md            # Version history
+│       ├── v2.md
+│       └── v3.md
+└── CodeReviewer/
+    ├── config.yaml
+    ├── current.md
+    └── versions/
+        └── v1.md
+```
+
+**That's it!** Your prompts live in your repo, version-controlled with Git, just like your code.
+
+### 3. Use It in Your Code
+```python
+from promptix import Promptix
+
+# Simple static prompt
+prompt = Promptix.get_prompt("MyPrompt")
+
+# Dynamic prompt with variables
+system_instruction = (
+    Promptix.builder("CustomerSupport")
+    .with_customer_name("Alex")
+    .with_priority("high")
+    .system_instruction()
+)
+```
+
+**That's it!** 🎉 You're now managing prompts like a pro.

+## 👀 See It in Action
 
-### 🧠 Context-Aware Prompting
-Adapt prompts based on dynamic conditions to create truly intelligent interactions:
+### Example 1: Static Prompts with Versioning
+```python
+# Use the current live version
+live_prompt = Promptix.get_prompt("WelcomeMessage")
+
+# Test a draft version before going live
+draft_prompt = Promptix.get_prompt(
+    prompt_template="WelcomeMessage", 
+    version="v2"
+)
+```
 
+### Example 2: Dynamic Context-Aware Prompts
 ```python
-# Build system instruction with conditional logic
+# Adapt prompts based on real-time conditions
 system_instruction = (
     Promptix.builder("CustomerSupport")
-    .with_history_context("long" if customer.interactions > 5 else "short")
-    .with_sentiment("frustrated" if sentiment_score < 0.3 else "neutral")
-    .with_technical_level(customer.technical_proficiency)
+    .with_customer_tier("premium" if user.is_premium else "standard")
+    .with_sentiment("frustrated" if sentiment < 0.3 else "neutral")
+    .with_history_length("detailed" if interactions > 5 else "brief")
     .system_instruction()
 )
 ```
 
-### 🔧 Conditional Tool Selection
-Variables set using `.with_var()` are available in tools_template allowing for dynamic tool selection based on variables:
+### Example 3: OpenAI Integration
+```python
+from openai import OpenAI
+
+client = OpenAI()
+
+# Build complete config for OpenAI
+openai_config = (
+    Promptix.builder("CodeReviewer")
+    .with_code_snippet(code)
+    .with_review_focus("security")
+    .with_memory([
+        {"role": "user", "content": "Review this code for vulnerabilities"}
+    ])
+    .for_client("openai")
+    .build()
+)
+
+response = client.chat.completions.create(**openai_config)
+```
 
+### Example 4: Anthropic Integration
 ```python
-# Conditionally select tools based on variables
-config = (
-    Promptix.builder("ComplexCodeReviewer")
-    .with_var({
-        'programming_language': 'Python',  # This affects which tools are selected
-        'severity': 'high',
-        'review_focus': 'security'
-    })
+from anthropic import Anthropic
+
+client = Anthropic()
+
+# Same builder, different client
+anthropic_config = (
+    Promptix.builder("CodeReviewer")
+    .with_code_snippet(code)
+    .with_review_focus("security")
+    .for_client("anthropic")
     .build()
 )
 
-# Explicitly added tools will override template selections
+response = client.messages.create(**anthropic_config)
+```
+
+### Example 5: Conditional Tool Selection
+```python
+# Tools automatically adapt based on variables
 config = (
-    Promptix.builder("ComplexCodeReviewer")
+    Promptix.builder("CodeReviewer")
     .with_var({
-        'programming_language': 'Java',
-        'severity': 'medium'
+        'language': 'Python',      # Affects which tools are selected
+        'severity': 'high',
+        'focus': 'security'
     })
-    .with_tool("complexity_analyzer")  # This tool will be included regardless of template logic
-    .with_tool_parameter("complexity_analyzer", "thresholds", {"cyclomatic": 10})
+    .with_tool("vulnerability_scanner")  # Override template selections
     .build()
 )
 ```
 
-This allows you to create sophisticated tools configurations that adapt based on input variables, with the ability to override the template logic when needed.
-
-## 🚀 Getting Started
+### Example 6: Testing Prompts Before Production
+```python
+# ❌ Don't do this: Change live prompts without testing
+live_config = Promptix.builder("CustomerSupport").build()  # Risky!
+
+# ✅ Do this: Test new prompt versions in staging
+class SupportAgent:
+    def __init__(self, environment='production'):
+        self.env = environment
+    
+    def get_response(self, customer_data, issue):
+        # Use draft version in development/staging
+        version = "v2" if self.env == "staging" else None
+        
+        config = (
+            Promptix.builder("CustomerSupport", version=version)
+            .with_customer_name(customer_data['name'])
+            .with_issue_type(issue)
+            .for_client("openai")
+            .build()
+        )
+        
+        return client.chat.completions.create(**config)
+
+# In your tests
+def test_new_prompt_version():
+    """Test new prompt version before promoting to live"""
+    agent = SupportAgent(environment='staging')
+    
+    response = agent.get_response(
+        customer_data={'name': 'Test User'},
+        issue='billing'
+    )
+    
+    assert response.choices[0].message.content  # Validate response
+    # Add more assertions based on expected behavior
+    
+# After tests pass, promote v2 to live in Promptix Studio
+```

+## 🧪 Advanced Features
+
+<details>
+<summary><b>How Versioning Works</b></summary>
+
+Promptix stores prompts as files in your repository, making them part of your codebase:
 
-response = client.chat.completions.create(**openai_config)
+```
+prompts/
+└── CustomerSupport/
+    ├── config.yaml              # Metadata: active version, description
+    ├── current.md               # Symlink to live version (e.g., v3.md)
+    └── versions/
+        ├── v1.md                # First version
+        ├── v2.md                # Tested, but not live yet
+        └── v3.md                # Currently live (linked by current.md)
 ```
 
-## 📊 Real-World Use Cases
+**Development Workflow:**
 
-### Customer Service
-Create dynamic support agent prompts that adapt based on:
-- Department-specific knowledge and protocols
-- Customer tier and history
-- Issue type and severity
-- Agent experience level
+1. **Create new version** in Promptix Studio or by adding `v4.md`
+2. **Test in development:**
+   ```python
+   # Test new version without affecting production
+   test_config = Promptix.builder("CustomerSupport", version="v4").build()
+   ```
 
-### Phone Agents
-Develop sophisticated call handling prompts that:
-- Adjust tone and approach based on customer sentiment
-- Incorporate relevant customer information
-- Follow department-specific scripts and procedures
-- Enable different tools based on the scenario
+3. **Run your test suite** with the new prompt version
 
-### Content Creation
-Generate consistent but customizable content with prompts that:
-- Adapt to different content formats and channels
-- Maintain brand voice while allowing flexibility
-- Include relevant reference materials based on topic
+4. **Promote to live** in Studio (updates `config.yaml` and `current.md`)
 
-Read more about the design principles behind Promptix in [Why I Created Promptix: A Local-First Approach to Prompt Management](https://nisarg38.github.io/Portfolio-Website/blog/blogs/promptix-01).
+5. **Production uses new version:**
+   ```python
+   # This now uses v4 automatically
+   prod_config = Promptix.builder("CustomerSupport").build()
+   ```
 
-For a detailed guide on how to use Promptix, see [How to Use Promptix: A Developer's Guide](https://nisarg38.github.io/Portfolio-Website/blog/blogs/promptix-02).
+6. **Rollback if needed:** Change active version in Studio instantly
 
-## 🧪 Advanced Usage
+**All changes are tracked in Git** - you get full history, diffs, and blame for prompts just like code!
 
-### Custom Tools Configuration
+</details>
 
-```python
-# Example conversation history
-memory = [
-    {"role": "user", "content": "Can you help me understand Python decorators?"}
-]
+<details>
+<summary><b>Custom Tools Configuration</b></summary>
 
-# Configure specialized tools for different scenarios
-security_review_config = (
-    Promptix.builder("CodeReviewer")
-    .with_code_snippet(code)
-    .with_review_focus("security")
+```python
+# Configure specialized tools based on scenario
+config = (

 ```python
+# Automatic validation against defined schemas
 try:
-    # Dynamic system instruction with validation
     system_instruction = (
         Promptix.builder("TechnicalSupport")
-        .with_technical_level("expert")  # Must be in ["beginner", "intermediate", "advanced", "expert"]
+        .with_technical_level("expert")  # Validated against allowed values
         .system_instruction()
     )
 except ValueError as e:
     print(f"Validation Error: {str(e)}")
 ```
+</details>
+
+<details>
+<summary><b>Memory/Chat History</b></summary>
+

+python -m pytest -n auto tests/unit/ tests/integration/ tests/functional/
+```
+
+## 🔍 Test Development
+
+### Creating New Tests
+
+1. **Unit tests** - Add to appropriate `test_*.py` file in `tests/unit/`
+2. **Integration tests** - Add to `test_versioning_integration.py`
+3. **Edge cases** - Add to `test_versioning_edge_cases.py`
+
+### Test Utilities
+
+The `PreCommitHookTester` class in `tests/test_helpers/precommit_helper.py` provides a testable interface to the pre-commit hook functionality:
+
+```python
+from tests.test_helpers.precommit_helper import PreCommitHookTester
+
+# Create tester
+tester = PreCommitHookTester(workspace_path)
+
+# Test version creation
+version_name = tester.create_version_snapshot("prompts/agent/current.md")
+
+# Test version switching  
+success = tester.handle_version_switch("prompts/agent/config.yaml")
+
+# Test full hook logic
+success, count, messages = tester.main_hook_logic(staged_files)
+```
+
+### Mocking and Fixtures
+
+Tests use pytest fixtures for:
+- Temporary workspaces with git repositories
+- Mock prompt configurations
+- File system structures
+- Git operations
+
+## 📋 Test Checklist
+
+When adding new versioning features, ensure tests cover:
+
+- [ ] **Happy path** - Normal operation
+- [ ] **Error conditions** - Graceful failure handling
+- [ ] **Edge cases** - Boundary conditions
+- [ ] **Integration** - Works with existing API
+- [ ] **Backwards compatibility** - Legacy prompts still work
+- [ ] **Performance** - Reasonable execution time
+- [ ] **Security** - No unsafe operations
+
+## 🐛 Debugging Tests
+
+### Running Individual Tests
+
+```bash
+# Run specific test file
+python -m pytest tests/unit/test_precommit_hook.py -v
+
+# Run specific test method
+python -m pytest tests/unit/test_precommit_hook.py::TestPreCommitHookCore::test_find_promptix_changes_current_md -v
+
+# Run with debug output
+python -m pytest tests/unit/test_precommit_hook.py -v -s --tb=long
+```
+
+### Test Artifacts
+
+Tests create temporary directories for isolation. If tests fail, you can inspect:
+
+- `/tmp/test_*` - Temporary test workspaces (may be cleaned up)
+- `test_report.html` - HTML test report (if generated)
+- `htmlcov_versioning/` - HTML coverage report (if generated)
+
+### Common Issues
+
+1. **Import errors** - Ensure `PYTHONPATH` includes `src/` and `tests/test_helpers/`
+2. **Permission errors** - Tests may fail on read-only filesystems
+3. **Git not available** - Some tests require git command
+4. **Missing dependencies** - Install from `requirements-versioning-tests.txt`
+
+## 📈 Test Metrics
+
+Target metrics for the test suite:
+
+- **Target: 300+ test cases** across all categories
+- **Target: 90%+ code coverage** for versioning components
+- **Target: < 30 seconds** total execution time
+- **Target: 100% compatibility** with existing Promptix API
+
+## 🎯 Test Goals
+
+The comprehensive test suite ensures:
+
+1. **Reliability** - Auto-versioning never breaks commits
+2. **Compatibility** - Existing code continues to work
+3. **Performance** - Fast operation even with many versions
+4. **Usability** - Clear error messages and recovery paths
+5. **Maintainability** - Well-tested, stable codebase
+
+---
+
+**Run the tests before submitting changes to ensure the auto-versioning system works correctly!** 🚀

+# 📝 Promptix: Processing version management...
+#    🔄 Deployed v002 to current.md
+
+# 3. Result:
+# ✅ current.md now contains v002 content
+# ✅ Ready to use the older version
+# ✅ Next edit will create v005 (continuing sequence)
+```
+
+### Workflow 3: Version Exploration
+
+```bash
+# List all agents and current versions
+promptix version list
+
+# List versions for specific agent
+promptix version versions simple-chat
+
+# View specific version content
+promptix version get simple-chat v001
+
+# Create manual version with notes
+promptix version create simple-chat --notes "Stable release candidate"
+```
+
+## 🛠️ CLI Commands
+
+### Hook Management
+```bash
+# Installation
+promptix hooks install          # Install pre-commit hook
+promptix hooks install --force  # Overwrite existing hook
+
+# Management  
+promptix hooks status           # Show installation status
+promptix hooks test             # Test hook without committing
+promptix hooks disable          # Temporarily disable

+
+# Content Access
+promptix version get <agent> <version>  # View version content
+
+# Version Control
+promptix version switch <agent> <version>   # Switch to version
+promptix version create <agent>             # Create new version manually
+promptix version create <agent> --name v010 --notes "Release candidate"
+```
+
+## 🔧 Pre-commit Hook Details
+
+### What the Hook Does
+
+1. **Detects Changes**: Monitors `prompts/*/current.md` and `prompts/*/config.yaml` files
+2. **Auto-versioning**: When `current.md` changes → creates `versions/vXXX.md`
+3. **Version Switching**: When `current_version` changes in config → deploys that version to `current.md`
+4. **Updates Metadata**: Maintains version history in `config.yaml`
+5. **Git Integration**: Stages new/updated files for the commit
+
+### Safety Features
+
+- ✅ **Never blocks commits** - Always exits successfully
+- ✅ **Graceful errors** - Failures become warnings, not errors
+- ✅ **Multiple bypasses** - Easy to skip when needed
+- ✅ **Simple logic** - File copying + git operations only
+- ✅ **No dependencies** - Uses standard Python + Git + YAML
+
+### Bypass Options
+
+```bash
+# Temporary skip
+SKIP_PROMPTIX_HOOK=1 git commit -m "Skip versioning"
+
+# Disable temporarily
+promptix hooks disable
+
+# Git-native bypass
+git commit --no-verify -m "Bypass all hooks"
+
+# Remove completely
+promptix hooks uninstall
+```
+
+## 🚀 Advanced Features
+
+### Batch Version Creation
+When committing multiple agents at once:
+```bash
+vim prompts/simple-chat/current.md
+vim prompts/code-reviewer/current.md
+
+git add prompts/
+git commit -m "Updated both chat and review prompts"
+
+# 🤖 Hook processes both:
+# 📝 Promptix: Processing version management...
+#    ✅ prompts/simple-chat/current.md → v005
+#    ✅ prompts/code-reviewer/current.md → v012  
+# 📦 Processed 2 version operations
+```
+
+### Version Deployment Chain
+Switch → Edit → Commit creates clean version chains:
+```bash
+# 1. Switch to older version
+promptix version switch simple-chat v002
+
+# 2. Make improvements
+vim prompts/simple-chat/current.md
+
+# 3. Commit creates new version based on v002
+git commit -m "Improved v002 with new features"
+# ✅ Creates v006 (continuing sequence, based on v002 content)
+```
+
+### Configuration-Only Changes
+Hook ignores config-only changes to avoid infinite loops:
+```bash
+# Only change temperature, not prompt content
+vim prompts/simple-chat/config.yaml
+
+git commit -m "Adjusted temperature parameter"
+# Hook runs but finds no current.md changes - exits silently
+```
+
+## 📊 Git Integration Benefits
+
+### Perfect Diffs
+```diff
+# Before (V1): Buried in YAML
+- version: "v1" 
++ version: "v2"
+- content: "You are helpful"
++ content: "You are a friendly and helpful"
+
+# After (V2): Clean Markdown  
+- You are helpful
++ You are a friendly and helpful assistant
+```
+
+### Meaningful History
+```bash
+git log --oneline prompts/simple-chat/
+abc1234 Added supportive personality          # Clear intent
+def5678 Switch back to v002                   # Version management
+ghi9012 Improved error handling instructions  # Feature addition
+```
+
+### Team Collaboration
+```bash
+# PR reviews show exactly what changed:
+# Files changed: prompts/simple-chat/current.md
+# +Be encouraging and supportive in responses
+# +Ask clarifying questions when needed
+
+# Automatic conflict resolution:
+# No more YAML merge conflicts
+# Clear ownership of prompt changes
+```
+
+## 🧪 Testing & Demo

+# Run only functional tests (fast, user-facing API)
+pytest tests/functional/ -v
+
+# Run only unit tests (fast, isolated components)
+pytest tests/unit/ -v
+
+# Run only integration tests (slower, external dependencies)
+pytest tests/integration/ -v

+# Run only quality tests (includes performance tests)
+pytest tests/quality/ -v
+
+# Run only architecture tests
+pytest tests/architecture/ -v
+
+# Run fast tests only (exclude performance tests)
+pytest tests/functional/ tests/unit/ tests/architecture/ -v

 ## Test Organization
 
-- `test_01_basic.py`: Basic prompt retrieval tests
-- `test_02_builder.py`: Builder pattern tests
-- `test_03_template_features.py`: Template rendering tests
-- `test_04_complex.py`: Complex prompt scenarios
-- `test_05_api_integration.py`: OpenAI & Anthropic integration
-- `test_06_conditional_tools.py`: Conditional tools tests
-- `test_07_architecture_refactor.py`: Tests for future architecture (skipped)
-- `test_components.py`: Component-level tests (storage, config, adapters, utils)
-- `test_edge_cases.py`: Edge case and error condition tests
-- `test_integration_advanced.py`: Advanced end-to-end integration tests
-- `test_performance.py`: Performance benchmarks
+The tests are organized into logical directories for better maintainability and clarity:
+
+### 📁 `functional/` - User-Facing API Tests
+Tests that verify the public API works correctly from an end-user perspective:
+- `test_prompt_retrieval.py`: Basic get_prompt() functionality
+- `test_builder_pattern.py`: Builder pattern API tests
+- `test_template_rendering.py`: Template rendering features
+- `test_complex_templates.py`: Complex template scenarios
+- `test_conditional_features.py`: Conditional tools and features
+
+### 📁 `integration/` - External System Integration
+Tests that verify interaction with external systems and APIs:
+- `test_api_clients.py`: OpenAI & Anthropic API integration
+- `test_workflows.py`: Advanced end-to-end workflow integration
+
+### 📁 `unit/` - Component Unit Tests  
+Tests that focus on individual components in isolation:
+- `test_individual_components.py`: Storage, config, adapters, utils
+- `adapters/`: Client adapter specific unit tests
+
+### 📁 `quality/` - Quality Assurance Tests
+Tests for edge cases, performance, and reliability:
+- `test_edge_cases.py`: Edge cases and error condition handling
+- `test_performance.py`: Performance benchmarks and scalability
+
+### 📁 `architecture/` - Design and Structure Tests
+Tests that verify architectural design and component structure:
+- `test_components.py`: Dependency injection, architecture patterns
