✅ Strengths

• Exemplary documentation: Comprehensive package-level documentation explaining the orchestrator module architecture
• Clear architectural vision: Documents the 5-module split with clear purpose statements for each module
• Maintainability focus: Explicitly states the design goal of making the codebase "easier to understand and maintain"
• Shared resource management: Clean separation of shared logger used across orchestrator modules
• High test coverage: 682 lines of tests demonstrate thorough validation of orchestrator functionality

📊 Analysis Details

This file serves as the architectural documentation hub for the compiler orchestrator modules. The package comment provides excellent guidance on the module structure:

// The compiler orchestrator is split into 5 focused modules for maintainability:
//
//   - orchestrator.go: Shared logger and constants used across orchestrator modules
//   - orchestrator_engine.go: Engine detection, validation, and setup logic
//   - orchestrator_frontmatter.go: Frontmatter parsing and validation
//   - orchestrator_tools.go: Tool configuration and MCP server setup
//   - orchestrator_workflow.go: Main workflow orchestration and YAML generation
```

The only code is a shared logger declaration, keeping this file purely focused on documentation and shared resources.

#### 💡 Recommendations

No significant improvements needed. This file exemplifies good architectural documentation practices.

### 2. `compiler_jobs.go` - Score: 83/100 ✅

**Rating**: Good  
**Size**: 528 lines  
**Git Hash**: `78b0516525b3b50c919ec7bd5f1c9865c70986d2`  
**Test File**: compiler_jobs_test.go (1,968 lines)

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 21/25 | Good |
| Readability | 17/20 | Good |
| Error Handling | 20/20 | Excellent |
| Testing & Maintainability | 18/20 | Good |
| Patterns & Best Practices | 7/15 | Acceptable |
| **Total** | **83/100** | **Good** |

#### ✅ Strengths

- **Excellent error handling**: All 16 error returns use `fmt.Errorf` with `%w` for proper error wrapping
- **Clear separation of concerns**: Functions are well-organized by responsibility (job building, dependency management, helper utilities)
- **Comprehensive testing**: Test-to-source ratio of 3.7x indicates thorough test coverage
- **Good logging**: Uses debug logger consistently for troubleshooting (`compilerJobsLog`)
- **Helper functions**: Utility functions like `jobDependsOnPreActivation`, `jobDependsOnAgent` are well-documented and focused

#### ⚠️ Issues Identified

1. **File Size (Low Priority)**
   - Current: 528 lines
   - While under the 800-line guideline, approaching medium size
   - Recommendation: Consider future split if significantly more functions are added

2. **Documentation Completeness (Low Priority)**
   - Most functions have clear documentation
   - Some helper functions could benefit from more detailed examples
   - Recommended: Add examples for complex dependency resolution functions

3. **Pattern Consistency (Medium Priority)**
   - Mix of receiver methods and helper functions
   - 14 receiver methods vs 2 helper functions
   - Recommendation: Consider if helper functions should be receiver methods for consistency

#### 📊 Function Analysis

**Total Functions**: 16
- **Receiver Methods** (`*Compiler`): 14 functions
- **Helper Functions**: 2 functions
- **Average Function Complexity**: Medium

**Key Functions**:
- `buildJobs()`: Main orchestration function (45 lines)
- `buildPreActivationAndActivationJobs()`: Complex dependency management (45 lines)
- `buildCustomJobs()`: Custom job processing with dependency inference (60+ lines)

#### 💡 Recommendations

1. **Maintain current structure**: File size is manageable; don't split unless growth continues
2. **Document dependency logic**: Add diagrams or comments explaining job dependency graph
3. **Extract configuration logic**: Consider extracting job config parsing into dedicated helpers

### 3. `compiler_yaml.go` - Score: 78/100 ✅

**Rating**: Good  
**Size**: 633 lines  
**Git Hash**: `78b0516525b3b50c919ec7bd5f1c9865c70986d2`  
**Test File**: compiler_yaml_test.go (1,113 lines)

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 18/25 | Acceptable |
| Readability | 15/20 | Acceptable |
| Error Handling | 20/20 | Excellent |
| Testing & Maintainability | 16/20 | Good |
| Patterns & Best Practices | 9/15 | Acceptable |
| **Total** | **78/100** | **Good** |

#### ✅ Strengths

- **Excellent error handling**: All error returns properly wrapped with context
- **ANSI code sanitization**: Thorough stripping of ANSI escape codes using `stringutil.StripANSIEscapeCodes()`
- **Good test coverage**: 1,113 test lines (1.8x ratio) ensure YAML generation correctness
- **Performance-conscious**: Pre-allocates string builder capacity (256KB) to minimize reallocations
- **Cross-platform compatibility**: Normalizes paths to Unix format using `filepath.ToSlash()`

#### ⚠️ Issues Identified

1. **File Size (Medium Priority)**
   - Current: 633 lines
   - Recommendation: Consider splitting into smaller focused modules:
     - `compiler_yaml_header.go`: Header and metadata generation
     - `compiler_yaml_prompt.go`: Prompt generation and chunking
     - `compiler_yaml_core.go`: Main YAML structure generation

2. **Function Complexity (Medium Priority)**
   - `generatePrompt()`: Long function handling multiple concerns (100+ lines)
   - `generateWorkflowHeader()`: Multiple responsibilities (metadata, imports, hashes)
   - Recommendation: Extract sub-functions for each responsibility

3. **Documentation Gaps (Low Priority)**
   - Comment density could be improved
   - Complex logic (especially in `generatePrompt`) needs more inline explanation
   - Recommendation: Add examples for runtime-import macro generation

4. **Magic Numbers (Low Priority)**
   - `maxChunkSize = 20900` in `splitContentIntoChunks` lacks explanation
   - `yaml.Grow(256 * 1024)` capacity allocation not documented
   - Recommendation: Add comments explaining size constraints

#### 📊 Function Analysis

**Total Functions**: 10
- **Receiver Methods** (`*Compiler`): 9 functions
- **Helper Functions**: 1 function (`splitContentIntoChunks`)

**Complex Functions Needing Attention**:
- `generatePrompt()`: Handles imports, chunking, expression extraction, runtime-import macros (~150 lines estimated)
- `generateWorkflowHeader()`: Multiple metadata concerns (description, source, imports, hash) (~60 lines)

#### 💡 Recommendations

1. **High Priority: Refactor `generatePrompt()`**
   - Extract into focused sub-functions:
     - `processImportedMarkdown()`
     - `generateRuntimeImportMacros()`
     - `extractMainWorkflowExpressions()`
     - `generateUnifiedPromptStep()`
   - This would improve readability and testability

2. **Medium Priority: Split File if Growth Continues**
   - Current size is acceptable but near the threshold
   - Future additions should trigger a split

3. **Low Priority: Improve Documentation**
   - Add examples for runtime-import macro format
   - Explain chunk size limits (GitHub Actions constraints)
   - Document expression extraction and substitution flow

### Common Patterns Across Files

#### ✅ Strengths

1. **Consistent Error Handling**: All files use proper error wrapping with `fmt.Errorf` and `%w`
2. **Strong Testing Culture**: All files have comprehensive test coverage (avg 1,254 test lines)
3. **Debug Logging**: Consistent use of logger package for troubleshooting
4. **Clear Naming**: Function and variable names clearly communicate intent
5. **Separation of Concerns**: Each file has a focused responsibility

#### ⚠️ Common Areas for Improvement

1. **Documentation Density**: Could benefit from more inline comments in complex functions
2. **Function Length**: Some functions exceed 50 lines and could be extracted
