#### ✅ Strengths

- **Excellent error handling**: Consistent error wrapping with context using `fmt.Errorf` with `%w` format
- **Clear naming**: Function names clearly describe intent (`CompileWorkflow`, `validateWorkflowData`, `generateAndValidateYAML`)
- **Good separation of concerns**: Distinct phases for validation, generation, and output writing
- **Helpful error formatting**: Custom `formatCompilerError` provides consistent, user-friendly error messages
- **Documentation**: Exported functions have godoc comments explaining purpose and usage

#### ⚠️ Issues Identified

1. **Oversized Functions** (High Priority)
   - `validateWorkflowData()`: **255 lines** - Far exceeds 50-line guideline
   - `generateAndValidateYAML()`: **82 lines** - Should be split
   - **Impact**: Difficult to understand, test, and modify

2. **Repetitive Error Handling** (Medium Priority)
   - 16+ instances of `if err != nil { return formatCompilerError(...) }`
   - **Recommendation**: Consider validation framework to reduce boilerplate

3. **Concrete Types Over Interfaces** (Low Priority)
   - Heavy use of concrete types limits testability
   - **Recommendation**: Introduce interfaces for compiler dependencies

#### 💡 Recommendations

1. **Split validateWorkflowData()** into focused validation functions:
   ```go
   - validateEngine() 
   - validateTools()
   - validatePermissions()
   - validateTriggers()
   ```

2. **Extract YAML generation steps** from `generateAndValidateYAML()`:
   ```go
   - prepareYAMLStructure()
   - applyWorkflowOptions()
   - validateYAMLSchema()
   ```

3. **Create validation helpers** to reduce error handling repetition
