+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+ComfyUI-KikoTools is a planned modular collection of custom ComfyUI nodes that will provide essential tools missing from the standard ComfyUI release. All nodes will be grouped under "ComfyAssets" in the ComfyUI interface. The project is designed for extensibility, allowing new tools to be added easily while maintaining clean separation of concerns.
+
+**Current Status**: Project is in initial planning phase. Only documentation and licensing files exist.
+
+## Architecture
+
+### Design Principles
+- **Modular Design**: Each tool is a separate, self-contained module
+- **ComfyAssets Grouping**: All nodes appear under the "ComfyAssets" category
+- **Test-Driven Development**: Every tool includes comprehensive tests
+- **Clean Interfaces**: Standardized input/output patterns across tools
+
+### Core Components
+- **Tool Registry**: Central registration system for all KikoTools nodes
+- **Base Classes**: Shared functionality for consistent tool behavior
+- **Individual Tools**: Self-contained modules for specific functionality
+
+### Current Tools
+
+#### 1. Resolution Calculator (First Tool)
+- **Purpose**: Calculate upscale resolution from image or latent inputs
+- **Inputs**: 
+  - Image or Latent tensor
+  - Scale factor (1, 2, 3, 1.2, 1.5, 2.0)
+- **Outputs**: 
+  - Width (INT)
+  - Height (INT)
+- **Target Models**: Flux and SDXL optimized
+- **Use Case**: Connect calculated dimensions to upscaler nodes
+
+## Technology Stack
+
+- **Backend**: Python with ComfyUI node patterns
+- **Node Framework**: ComfyUI INPUT_TYPES, RETURN_TYPES, execute() patterns
+- **Testing**: pytest with ComfyUI test fixtures
+- **Code Quality**: black, flake8, mypy
+- **Integration**: ComfyUI execution queue and tensor systems
+
+## Development Commands
+
+**Note**: These commands are planned for when the project structure is implemented.
+
+### Initial Setup
+```bash
+# Create basic project structure
+mkdir -p kikotools/{base,tools} tests/{unit,integration,fixtures} scripts examples
+
+# Create entry point files
+touch __init__.py kikotools/__init__.py
+```
+
+### Code Quality (Future)
+```bash
+# Format Python code
+black .
+
+# Python linting
+flake8 .
+
+# Type checking
+mypy .
+```
+
+### Testing (Future TDD Workflow)
+```bash
+# Run all tests
+pytest tests/
+
+# Run tests for specific tool
+pytest tests/unit/tools/test_{tool_name}.py
+
+# Test coverage
+pytest --cov=kikotools tests/
+```
+
+## Project Structure (Planned)

+
+## Key ComfyUI Integration Points
+
+### Node Registration Pattern
+```python
+# Each tool follows this pattern in kikotools/tools/{tool_name}/node.py
+class ResolutionCalculatorNode:
+    @classmethod
+    def INPUT_TYPES(cls):
+        return {
+            "required": {
+                "scale_factor": ("FLOAT", {"default": 2.0, "min": 1.0, "max": 8.0, "step": 0.1}),
+            },
+            "optional": {
+                "image": ("IMAGE",),
+                "latent": ("LATENT",),
+            }
+        }
+    
+    RETURN_TYPES = ("INT", "INT")
+    RETURN_NAMES = ("width", "height")
+    FUNCTION = "calculate_resolution"
+    CATEGORY = "ComfyAssets"  # All tools use this category
+    
+    def calculate_resolution(self, scale_factor, image=None, latent=None):
+        # Implementation here
+        pass
+```
+
+### Base Node Class
+- Provides consistent "ComfyAssets" categorization
+- Standardizes error handling and logging
+- Implements common validation patterns
+- Ensures consistent return type handling
+
+### Tool Registry System
+- Automatic discovery of tools in `kikotools/tools/`
+- Dynamic node registration during ComfyUI startup
+- Version compatibility checking
+- Dependency validation
+
+## Test-Driven Development (TDD) Workflow
+
+### 1. Write Tests First
+```python
+# tests/unit/tools/test_resolution_calculator.py
+def test_resolution_calculator_with_image():
+    """Test resolution calculation with image input."""
+    # Arrange
+    node = ResolutionCalculatorNode()
+    test_image = create_test_image(512, 512)  # fixture
+    scale_factor = 2.0
+    
+    # Act
+    width, height = node.calculate_resolution(scale_factor, image=test_image)
+    
+    # Assert
+    assert width == 1024
+    assert height == 1024
+
+def test_resolution_calculator_with_latent():
+    """Test resolution calculation with latent input."""
+    # Similar pattern for latent inputs
+    pass
+```
+
+### 2. Run Tests (Should Fail)
+```bash
+pytest tests/unit/tools/test_resolution_calculator.py -v
+```
+
+### 3. Implement Minimal Code
+```python
+# kikotools/tools/resolution_calculator/logic.py
+def calculate_upscale_resolution(input_tensor, scale_factor):
+    """Calculate new resolution based on input and scale factor."""
+    # Minimal implementation to pass tests
+    pass
+```
+
+### 4. Refactor and Expand
+- Add error handling
+- Optimize for Flux/SDXL specific requirements
+- Add comprehensive validation
+- Implement edge case handling
+
+### 5. Integration Testing
+```python
+# tests/integration/test_workflow_execution.py
+def test_resolution_calculator_in_workflow():
+    """Test resolution calculator in full ComfyUI workflow."""
+    workflow = load_test_workflow("resolution_calculator_example.json")
+    result = execute_comfyui_workflow(workflow)
+    assert result.success
+```
+
+## Tool-Specific Implementation Notes
+
+### Resolution Calculator
+- **Input Validation**: Handle both image and latent tensors
+- **Scale Factors**: Support integer (1, 2, 3) and float (1.2, 1.5, 2.0) multipliers
+- **Model Optimization**: Consider Flux and SDXL specific resolution requirements
+- **Output Format**: Integer width/height suitable for upscaler node connections
+- **Error Handling**: Graceful handling of invalid inputs or edge cases
+
+### Future Tools (Planned)
+- Batch Image Processor
+- Advanced Prompt Utilities
+- Model Management Tools
+- Custom Sampling Methods
+
+## Development Workflow
+
+### Adding a New Tool
+1. **Plan**: Define tool purpose, inputs, outputs, and test cases
+2. **Generate**: Use `python scripts/create_tool.py --name "NewTool"`
+3. **Test**: Write comprehensive tests following TDD principles
+4. **Implement**: Build tool logic with proper ComfyUI integration
+5. **Register**: Add tool to registry and validate registration
+6. **Document**: Update examples and documentation
+7. **Validate**: Test in real ComfyUI environment with actual workflows
+
+### Code Quality Standards
+- **Type Hints**: Full type annotation for all functions
+- **Documentation**: Docstrings for all public methods and classes
+- **Testing**: Minimum 90% test coverage for all tools
+- **Linting**: Pass all flake8 and mypy checks
+- **Formatting**: Auto-formatted with black
+
+### Release Process
+1. Run full test suite: `pytest tests/`
+2. Validate in ComfyUI: `python scripts/validate_nodes.py`
+3. Update version numbers and changelog
+4. Create example workflows demonstrating new features
+5. Update ComfyUI-Manager compatibility metadata

+```bash
+pip install google-generativeai
+```
+
+### 3. Configure API Key
+
+Choose one of these methods:
+
+1. **Environment Variable** (Recommended):
+   ```bash
+   export GEMINI_API_KEY="your-api-key-here"
+   ```
+
+2. **Config File**:
+   Create `gemini_config.json` in your ComfyUI root directory:
+   ```json
+   {
+     "api_key": "your-api-key-here"
+   }
+   ```
+
+3. **Node Input**:
+   Enter the API key directly in the node's `api_key` field
+
+## Inputs
+
+- **image** (IMAGE): The image to analyze
+- **prompt_type** (DROPDOWN): Type of prompt to generate
+  - `flux`: Detailed artistic prompts with quality markers
+  - `sdxl`: Positive/negative prompt pairs with weight emphasis
+  - `danbooru`: Anime-style booru tags with underscores
+  - `video`: Motion and temporal descriptions for video generation
+- **api_key** (STRING, optional): Gemini API key if not set elsewhere
+- **custom_prompt** (STRING, optional): Override template with custom system prompt
+
+## Outputs
+
+- **prompt** (STRING): Generated prompt text
+- **negative_prompt** (STRING): Negative prompt (only populated for SDXL format)
+
+## Prompt Type Details
+
+### FLUX Format
+Generates detailed prompts optimized for FLUX models:
+- Starts with main subject and action
+- Includes style and medium descriptors
+- Adds lighting and atmosphere details
+- Uses quality markers like "4K", "highly detailed", "award-winning"
+
+Example output:
+```
+majestic mountain landscape at golden hour, oil painting style, dramatic lighting with sun rays piercing through clouds, wide angle composition, warm color palette with orange and purple hues, highly detailed, 4K resolution, trending on ArtStation, photorealistic rendering
+```
+
+### SDXL Format
+Generates positive and negative prompt pairs:
+- Detailed positive prompts with weight emphasis
+- Comprehensive negative prompts to avoid common issues
+- Uses parentheses for emphasis: `(detailed eyes:1.2)`
+
+Example output:
+```
+Positive: beautiful woman, (detailed eyes:1.2), flowing red dress, golden hour lighting, professional photography, 85mm lens, shallow depth of field, bokeh, high resolution, masterpiece
+Negative: low quality, blurry, distorted features, bad anatomy, poorly drawn, amateur, oversaturated, jpeg artifacts
+```
+
+### Danbooru Format
+Generates booru-style tags for anime artwork:
+- Uses underscores for multi-word concepts
+- Includes character count descriptors (1girl, 2boys)
+- Orders tags from most to least important
+
+Example output:
+```
+1girl, solo, long_hair, blue_eyes, blonde_hair, school_uniform, serafuku, pleated_skirt, thighhighs, smile, looking_at_viewer, classroom, sitting, desk, window, sunlight, highres, masterpiece
+```
+
+### Video Format
+Generates prompts for video generation models:
+- Describes motion and camera movements
+- Includes temporal markers and transitions
+- Specifies technical details like fps and duration
+
+Example output:
+```
+Aerial shot slowly descending toward a misty forest at dawn, camera smoothly transitions to tracking shot following a deer through the trees, photorealistic style, soft golden hour lighting with fog, 10 second duration, 4K resolution 24fps, ending with close-up of deer looking at camera
+```
+
+## Custom System Prompts
+
+You can override any template by providing your own system prompt. This is useful for:
+- Specialized use cases
+- Different language outputs
+- Custom formatting requirements
+- Integration with specific workflows
+
+Example custom prompt:
+```
+You are an expert at analyzing images and creating simple, concise descriptions.
+Focus only on the main subject and primary colors.
+Keep your response under 50 words.
+```
+
+## Error Handling
+
+The node provides clear error messages for common issues:
+- Missing API key
+- API request failures
+- Invalid image inputs
+- Rate limiting
+
+Errors are displayed in the prompt output for easy debugging.
+
+## Tips
+
+1. **API Usage**: Gemini has generous free tier limits, but be mindful of rate limits
+2. **Image Quality**: Higher resolution images provide better analysis results
+3. **Prompt Refinement**: You can chain multiple Gemini nodes with different custom prompts
+4. **Caching**: Results are not cached, so identical images will make new API calls
+
+## Example Workflow
+
+1. Load an image using Load Image node
+2. Connect to Gemini Prompt Engineer
+3. Select appropriate prompt_type for your target model
+4. Connect prompt output to your generation model
+5. For SDXL, connect both prompt and negative_prompt outputs
+
+## Troubleshooting
+
+**"API key not found" error**:
+- Check environment variable is set correctly
+- Verify config file path and JSON format
+- Try entering key directly in node
+
+**"No response generated" error**:
+- Check internet connection
+- Verify API key is valid
+- Image might be too large (resize if needed)
+
+**Import error for google-generativeai**:
+- Run `pip install google-generativeai` in your ComfyUI environment
+- Restart ComfyUI after installation

+
+When analyzing an image, systematically observe and document:
+
+1. **Subject & Composition**
+   - Primary subjects and their positions
+   - Background elements and environment
+   - Overall composition and framing
+   - Perspective and camera angle
+
+2. **Visual Style & Technique**
+   - Art style (photorealistic, illustration, painting, etc.)
+   - Rendering technique (digital art, oil painting, watercolor, etc.)
+   - Level of detail and texture quality
+   - Any specific artistic influences or movements
+
+3. **Lighting & Atmosphere**
+   - Light sources and direction
+   - Time of day/lighting conditions
+   - Shadows and highlights
+   - Overall mood and atmosphere
+
+4. **Colors & Tones**
+   - Color palette and dominant colors
+   - Color temperature (warm/cool)
+   - Contrast and saturation levels
+   - Any color grading or filters
+
+5. **Details & Textures**
+   - Surface textures and materials
+   - Fine details and patterns
+   - Quality indicators (4K, 8K, high resolution, etc.)
+
+Format your FLUX prompt following these guidelines:
+- Start with the main subject and action
+- Add style and medium descriptors
+- Include lighting and atmosphere details
+- Specify quality markers and technical aspects
+- Use precise, descriptive language
+- Separate concepts with commas
+- Order from most to least important elements
+
+Example output format:
+"[main subject and action], [style/medium], [lighting/atmosphere], [composition details], [color descriptions], [quality markers], [additional artistic details]"
+
+Remember: FLUX responds well to specific artistic references, quality indicators like "highly detailed," "4K," "award-winning," and style descriptors like "trending on ArtStation" or "photorealistic."
