🔍 Compiler Code Quality Analysis Report

Analysis Date: 2026-06-24 · Git Commit: 433c534 · Overall Status: ✅ All 3 files meet quality standards

---

Executive Summary

Today's analysis covered compiler_safe_outputs_job.go, compiler_yaml.go, and compiler_yaml_main_job.go — 3,103 source lines total. All three files improved over their previous scores (batch avg: +7 pts), and all exceed the 75-point human-written quality threshold with a batch average of 80/100.

Universal strengths: every fmt.Errorf in all three files uses %w wrapping (15/15 — perfect), average comment density is 27.7%, and two of three files have ≥1.4× test-to-source ratios. The primary concern is generator function size: YAML-builder functions regularly grow past 100 lines, reducing readability and testability.

Historical Trends

File	Previous	Today	Change
compiler_safe_outputs_job.go	78	83	+5 ⬆️
compiler_yaml.go	73	78	+5 ⬆️
compiler_yaml_main_job.go	67	78	+11 ⬆️
Batch average	72.7	79.7	+7.0 ⬆️

compiler_yaml_main_job.go saw the largest single-session improvement (+11 pts) due to the new phased decomposition pattern and highest comment density (33.5%) in the updated commit.

Repository-wide average (all 9 tracked files): 81.2/100

Actionable Recommendations

High Priority

1. Split generatePrompt in compiler_yaml.go (294 lines): extract chunk splitting, expression substitution, and bash step emission into sub-helpers — largest readability gain available (~1-2 hrs)

Medium Priority

2. Extract insertAppTokenStep from buildSafeOutputsJobFromParts (239 lines) in compiler_safe_outputs_job.go (~1 hr)
3. Increase test coverage for compiler_yaml_main_job.go from 0.87× to ≥1.0× — focus on multi-checkout, MCP gateway, guard variable paths (~2-4 hrs)

Long-term

4. Extract compiler_yaml_prompt.go: move generatePrompt, extractPromptChunksFromMarkdown, splitContentIntoChunks, writePromptBashStep (~400 lines) out of compiler_yaml.go
5. Function-length lint rule: 120-line ceiling for YAML generators, 50-line ceiling for logic functions

Conclusion

All analyzed files meet quality standards. Error handling is perfect (15/15 %w wraps), test coverage is strong on 2/3 files, and compiler_yaml_main_job.go showed the biggest improvement (+11 pts) this cycle. The single highest-leverage action is splitting generatePrompt (294 lines) in compiler_yaml.go.
