# Coding Guidelines

# Code Length and Structure Guidelines
- **Reuse code blocks whenever possible.** If similar functionality exists in previously generated files within this project, reference and extend that code rather than rewriting from scratch. Build incrementally on existing code patterns.
- **Do not fallback anywhere.** Raise errors and terminate program rather than silently falling back to default values. Always require explicit configuration values rather than silently using defaults. 

# Code Review and Testing Guidelines

### Core Principles
- **Review-Only Mode**: When conducting code reviews, analyze and provide feedback without modifying the existing code
- **Isolated Testing**: Write standalone, focused tests for individual components rather than executing the entire codebase
- **Documentation**: Document all findings systematically for future reference

### Review Process
1. **Analysis Phase**

   - Examine code structure, logic, and patterns
   - Identify potential issues, bugs, or areas for improvement
   - Assess code quality, readability, and maintainability

   - **Mathematical Verification**: If the code implements mathematical derivations or formulas, carefully verify that the implementation faithfully represents the mathematical concepts, including:
     - Correct formula translation
     - Proper handling of edge cases and numerical stability
     - Appropriate precision and rounding considerations
     - Accurate implementation of mathematical operations and their order

   - **Performance Considerations**
      - Identify computational bottlenecks
      - Review memory usage patterns

2. **Testing Phase**
   - **Test Strategy**
      - Create minimal, isolated test cases for specific functions or modules
      - Focus on unit tests that validate individual pieces of functionality
      - Avoid running the full application unless explicitly necessary
   
   - **Test Coverage**
      - Ensure critical paths are tested
      - Include edge cases and boundary conditions
      - Test error handling scenarios
      - Validate expected exceptions are raised
   
   - **Test Organization**
      - Place all tests in `tests/` directory
      - Follow naming convention: `test_<module_name>.py`
      - Group related tests in test classes
      - Use descriptive test method names

3. **Documentation Phase**
   - Summarize findings in a markdown file within `Development/CodeReview/`
   - Use descriptive filenames: `<component>-review-YYYY-MM-DD.md`
   - **Important**: Never overwrite existing review documents; always create new files with unique names


# Planing Guideline

Sometimes you will be asked to assist with planning. In such cases, first complete the comprehensive analysis outlined below. Do not revise any existing code until you are explicitly directed to do so.

#### 1. Requirements Analysis
- **Understand the Goal**
  - Clearly define what needs to be achieved
  - Identify success criteria and metrics
  - List functional and non-functional requirements

#### 2. Design Phase
- Break down into manageable tasks
- Define clear, step-to-step milestones, but no need to estimate time requirements. 
- Identify potential risks and mitigation strategies
- **Important:** in full-scale training, I will use a cluster without Internet connection. Please take this into account, e.g., when using tools like wandb. 

#### 3. Documentation
- **File Organization**
  - Create plan documents in `Development/Plan/`
  - Use descriptive filenames: `<feature>-plan-YYYY-MM-DD.md`
  - Never overwrite existing plans; create new versions

- **Plan Document Structure**
  ```markdown

# Debugging Guideline

Occasionally, you will receive a bug report and be asked to assist with debugging. In such cases, first complete the comprehensive analysis outlined below. Do not revise any existing code until you are explicitly directed to do so.

#### 1. Problem Analysis
- **Issue Documentation**
  - Record exact error messages and stack traces
  - Document reproduction steps
  
- **Root Cause Investigation**
  - Form hypotheses about potential causes
  - Identify affected components

#### 2. Debugging Strategy
- **Isolation Approach**
  - Create minimal reproducible examples
  - Isolate the problem to specific components
  
- **Diagnostic Tools (if necessary)**
  - Add strategic logging statements
  - Use debugger breakpoints effectively
  - Employ profiling tools for performance issues
  - Utilize memory analysis for leak detection

#### 3. Testing & Validation
- **Test Creation**
  - Write tests that reproduce the bug in `tests/debug/`
  - Create tests that verify the fix
  - Ensure no new issues are introduced
  - Test edge cases around the fix

#### 4. Documentation
- **File Organization**
  - Create debug documents in `Development/Debug/`
  - Use descriptive filenames: `<issue>-debug-YYYY-MM-DD.md`
  - Link to related test files
  
- **Debug Document Structure**
  ```markdown
  # Debug Report: [Issue Description]
