##### ✅ Strengths

- **Excellent error wrapping** - 16 instances of `fmt.Errorf` with `%w`, enabling proper error chain inspection
- **Comprehensive documentation** - 17 documented functions with clear explanations
- **Good function decomposition** - Most functions stay under 50 lines (average: 37 lines)
- **Consistent logging** - Uses `compilerJobsLog` throughout for debugging
- **Clear responsibility** - Job building logic is well-isolated

##### ⚠️ Issues Identified

1. **Long Function - buildCustomJobs (High Priority)**
   - **Lines**: ~150 lines (353-503)
   - **Issue**: Complex nested logic for extracting job properties (needs, permissions, outputs, steps, secrets)
   - **Impact**: Difficult to test, understand, and modify
   - **Recommendation**: Break into focused helpers:
     - `extractJobDependencies()` - Handle needs extraction
     - `extractJobPermissions()` - Handle permissions
     - `extractJobOutputs()` - Handle outputs
     - `extractJobSteps()` - Handle steps
     - `validateCustomJob()` - Validation logic

2. **Missing Test Coverage (High Priority)**
   - ❌ **No `compiler_jobs_test.go` file found**
   - **Impact**: Critical job-building logic lacks test coverage
   - **Risk**: Changes to job generation could introduce bugs undetected
   - **Recommendation**: Create test file with coverage for:
     - `buildCustomJobs()` - Test various job configurations
     - `buildPreActivationAndActivationJobs()` - Test dependency resolution
     - `referencesCustomJobOutputs()` - Test pattern matching
     - `jobDependsOnAgent()`, `jobDependsOnPreActivation()` - Test dependency detection

3. **No Error Recovery (Low Priority)**
   - Functions fail entirely on first error
   - Consider graceful degradation for non-critical errors

##### 💡 Recommendations

1. **URGENT: Create test file** - Add `compiler_jobs_test.go` with table-driven tests for all public functions
2. **Refactor `buildCustomJobs()`** - Split into 4-5 smaller helpers (estimated effort: 3-4 hours)
3. **Document error conditions** - Add examples of error cases in godoc comments
4. **Add validation helpers** - Create reusable validation functions for job configuration

- **ANSI code sanitization** - Properly strips escape codes from YAML output

##### ⚠️ Issues Identified

1. **Very Long Functions (High Priority)**
   
   **`generateCreateAwInfo` - 155 lines (393-547)**
   - **Issue**: Generates complex JavaScript object for aw_info.json with extensive conditionals
   - **Impact**: Difficult to understand, test individual sections, and modify safely
   - **Recommendation**: Extract into focused generators:
     - `generateAwInfoCore()` - Basic metadata
     - `generateAwInfoRuntimes()` - Runtime configuration
     - `generateAwInfoTools()` - Tool configuration
     - `generateAwInfoPermissions()` - Permissions handling
     - `generateAwInfoCustomFields()` - Optional fields
   
   **`generatePrompt` - 131 lines (237-367)**
   - **Issue**: Processes imports, generates runtime-import macros, handles expressions
   - **Impact**: Multiple responsibilities in one function
   - **Recommendation**: Split into:
     - `processImports()` - Import handling
     - `generateRuntimeMacros()` - Macro generation
     - `processPromptExpressions()` - Expression handling

2. **Missing Documentation (Low Priority)**
   - `generateYAML` - Public method lacks godoc comment
   - `splitContentIntoChunks` - Utility function needs documentation
   - **Recommendation**: Add godoc comments explaining purpose and parameters

3. **File Size (Medium Priority)**
   - Current: 636 lines
   - With refactoring of two long functions, could reduce to ~450 lines
   - Consider splitting into:
     - `compiler_yaml_generation.go` - Main YAML structure
     - `compiler_yaml_awinfo.go` - aw_info.json generation
     - `compiler_yaml_prompts.go` - Prompt generation

##### 💡 Recommendations

1. **Refactor `generateCreateAwInfo`** (155 lines) - Split into 5 focused helper functions (estimated effort: 4-6 hours)
2. **Refactor `generatePrompt`** (131 lines) - Extract import/macro/expression handling (estimated effort: 2-3 hours)
3. **Add missing documentation** - Document `generateYAML` and `splitContentIntoChunks` (estimated effort: 15 minutes)
4. **Consider file split** - If refactoring doesn't reduce size sufficiently, split into 3 focused files

##### 📊 Quality Metrics

   • Approach: Split into compiler_yaml_generation.go, compiler_yaml_awinfo.go, compiler_yaml_prompts.go
   • Benefit: Improved navigability, clearer module boundaries

7. Standardize function length guidelines

   • Proposal: Enforce 50-line soft limit, 100-line hard limit for new code
   • Tooling: Consider adding a linter rule (e.g., funlen linter)
   • Exceptions: Document any exceptions with justification comments

8. Establish minimum test coverage

   • Target: 80% coverage for compiler package
   • Tool: Add coverage checks to CI pipeline
   • Policy: Require tests for all new functions >20 lines
