✅ Strengths

• Exceptional test coverage: 1,457 test lines across 43 test functions (2.71:1 ratio) demonstrates strong commitment to quality
• Clear orchestration architecture: Well-defined phases with typed result structures for data flow
• Excellent separation of concerns: Orchestration split into 5 focused modules (orchestrator.go, orchestrator_engine.go, orchestrator_frontmatter.go, orchestrator_tools.go, orchestrator_workflow.go)
• Strong error handling: 5 instances of proper error wrapping with fmt.Errorf and %w
• Comprehensive documentation: Package-level comments clearly explain the orchestration architecture
• Consistent logging: Uses structured logger (orchestratorWorkflowLog) throughout

⚠️ Issues Identified

1. Comment density (Low Priority)

### 2. `compiler_yaml.go` - Score: 76/100 ✅

**Rating**: Good  
**Size**: 633 lines  
**Git Hash**: `bcfb18a9f404718920dc1608ba3d1b4ddf7f7b28`

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 20/25 | Good |
| Readability | 15/20 | Acceptable |
| Error Handling | 16/20 | Good |
| Testing & Maintainability | 13/20 | Acceptable |
| Patterns & Best Practices | 12/15 | Good |
| **Total** | **76/100** | **Good** |

#### ✅ Strengths

- **Focused YAML generation**: Clean separation of header generation, job building, and validation
- **String builder pattern**: Efficient YAML construction using `strings.Builder`
- **Good error handling foundation**: Contextual error messages in validation functions
- **Consistent logging**: Uses `compilerYamlLog` for debugging YAML generation
- **Organized imports**: Clean dependency management

#### ⚠️ Issues Identified

1. **File size (Medium Priority)**
   - Current: 633 lines (slightly over 600-line ideal target)
   - Recommendation: Consider splitting into `compiler_yaml_generation.go` (header, prompt, job building) and `compiler_yaml_helpers.go` (utility functions, validation)
   - Estimated effort: 2-3 hours

2. **Error wrapping gaps (Medium Priority)**
   - Current: Only 4 instances of `fmt.Errorf` with `%w`
   - Issue: Some errors are passed through without additional context
   - Example: Errors from helper functions may lack workflow-specific context
   - Recommendation: Audit error return paths and add contextual wrapping

3. **High string literal count (Low Priority)**
   - Current: 228 string literals
   - Context: YAML generation naturally requires many strings, but consider extracting constants for repeated patterns
   - Recommendation: Extract common YAML keys and patterns into named constants

4. **Test coverage (Medium Priority)**
   - Current: Moderate test coverage
   - Recommendation: Add tests for edge cases in YAML generation, especially for complex expression handling

#### 💡 Recommendations

1. **Split file for maintainability**:
   - `compiler_yaml_generation.go`: Core YAML generation logic (header, jobs, workflow structure)
   - `compiler_yaml_helpers.go`: Utility functions (splitContentIntoChunks, expression handling, validation)
   - Benefits: Easier navigation, clearer responsibility boundaries

2. **Enhance error context**: Review all error return paths and ensure proper wrapping:
   ```go
   // Instead of:
   return err
   
   // Use:
   return fmt.Errorf("failed to generate YAML header for workflow %s: %w", data.Name, err)
   ```

3. **Improve test coverage**: Focus on:
   - Edge cases in content chunking (very long lines, empty content)
   - Expression extraction and replacement
   - YAML header generation with various frontmatter combinations

4. **Add inline comments**: Document complex YAML generation decisions, especially:
   - Why specific YAML structure choices were made
   - How expressions are processed and why
   - Chunk size calculations and rationale

#### 📊 Analysis Details

```
Function Count: 10
Nesting Depth: 54 conditionals
String Literals: 228 (expected for YAML generation)
Error Wrapping: 4 instances (could be improved)
Test Coverage: Moderate (needs enhancement)
```

### 3. `compiler_safe_outputs.go` - Score: 81/100 ✅

**Rating**: Good  
**Size**: 491 lines  
**Git Hash**: `bcfb18a9f404718920dc1608ba3d1b4ddf7f7b28`

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 21/25 | Excellent |
| Readability | 16/20 | Good |
| Error Handling | 15/20 | Acceptable |
| Testing & Maintainability | 16/20 | Good |
| Patterns & Best Practices | 13/15 | Excellent |
| **Total** | **81/100** | **Good** |

#### ✅ Strengths

- **Well-sized file**: 491 lines is comfortably under the 600-line target, leaving room for future enhancements
- **Modular structure**: Clear separation between parsing on-section, merging safe-jobs, and applying defaults
- **Strong separation of concerns**: Each function has a focused responsibility
- **Consistent logging**: Uses `compilerSafeOutputsLog` throughout for debugging
- **Good test coverage**: Dedicated test file with comprehensive test scenarios

#### ⚠️ Issues Identified

1. **Error wrapping deficit (High Priority)**
   - Current: Only 2 instances of `fmt.Errorf` with `%w`
   - Issue: Most errors are passed through without additional context
   - Impact: Debugging safe-outputs issues becomes harder without contextual error messages
   - Recommendation: Add error wrapping to all error return paths
   - Estimated effort: 1-2 hours

2. **High nesting depth (Medium Priority)**
   - Current: 74 conditionals (highest among analyzed files)
   - Issue: Complex nested if/else logic reduces readability
   - Functions affected: `parseOnSection`, `applyDefaultTools`, merge functions
   - Recommendation: Extract validation logic into separate helper functions:
     ```go
     // Instead of deeply nested if/else:
     if condition1 {
         if condition2 {
             if condition3 {
                 // logic
             }
         }
     }
     
     // Use early returns and helper functions:
     if !condition1 {
         return defaultValue, nil
     }
     return processCondition2And3(value)
     ```

3. **Multiple responsibilities (Low Priority)**
   - Some functions handle parsing, validation, AND merging
   - Example: `parseOnSection` extracts reaction, validates it, and sets workflow data
   - Recommendation: Consider separating extraction, validation, and application into distinct phases

4. **Comment density (Low Priority)**
   - Current: Estimated 3-4% comment density
   - Recommendation: Add inline comments for complex safe-outputs configuration logic

#### 💡 Recommendations

1. **Add comprehensive error wrapping** (High Priority):
   ```go
   // Add context to all error returns
   func (c *Compiler) parseOnSection(frontmatter map[string]any, workflowData *WorkflowData, markdownPath string) error {
       if err := validateReaction(reaction); err != nil {
           return fmt.Errorf("invalid reaction in on-section for workflow %s: %w", workflowData.Name, err)
       }
       // ... more error wrapping
   }
   ```

2. **Reduce nesting depth** (Medium Priority):
   - Extract nested validation logic into helper functions
   - Use early returns to flatten control flow
   - Consider using helper functions like `extractWithDefault`, `validateAndSet`

3. **Split responsibilities** (Low Priority):
   - Separate extraction logic: `extractReactionFromOn`, `extractLockForAgentFromOn`
   - Separate validation logic: `validateReaction`, `validateLockForAgent`
   - Separate application logic: `applyReactionToWorkflow`, `applyLockForAgentToWorkflow`

4. **Add inline comments**: Document complex configuration merging logic, especially:
   - Why certain defaults are applied
   - How conflicts are detected and resolved
   - The interaction between safe-outputs, safe-jobs, and GitHub tool configuration

#### 📊 Analysis Details

```
Function Count: 7
Nesting Depth: 74 conditionals (highest complexity)
String Literals: 137
Error Wrapping: 2 instances (needs significant improvement)
Test Coverage: Good (dedicated test file exists)
