âClean code always looks like it was written by someone who cares.â â Robert C. Martin
âAnd deterministic cleanups show they cared every day.â â You
đ± What Is Hygiene-Driven Refactoring?
Hygiene-Driven Refactoring is the practice of making small, consistent, and intentional improvements to codeânot just when features demand it, but as a habit. It treats code hygiene as non-negotiable, like brushing your teeth: you donât do it only when thereâs a cavity.
Itâs not yak-shaving. Itâs code stewardship.
đ§ The Deterministic Principle
Deterministic Cleanups are predictable, repeatable, and reviewable.
- đ Predictable: Everyone knows when and why the cleanup is happening.
- đ Reviewable: It produces low-noise, high-trust diffs.
- đ§© Repeatable: Itâs not a âdrive-byâ refactor, itâs part of your sprint hygiene.
Think of it as DevOps for your code quality.
đ The Manifesto
1. Refactor with Purpose, Not Panic
Donât wait for tech debt to cause pain. Eliminate mold, not just termites.
2. Small Is Strategic
One rename. One extraction. One fix. Thatâs hygiene. Thatâs momentum.
3. Automate What You Can
Use linters, formatters, code analyzers. Determinism loves tools.
4. Treat Hygiene Like Testing
Hygiene isn’t a “nice to have”âit’s a pillar of reliability.
5. Leave the Campground Cleaner
You donât need to fix everythingâjust fix something.
6. Codify and Share Patterns
Create refactoring checklists. Write before/after examples. Make it a team sport.
7. Make Hygiene Trackable
Track refactoring PRs. Measure code churn vs. quality. Give hygiene visibility.
8. No Feature Left Behind
Every feature PR should include a hygiene pass. Just like writing docs or tests.
9. Refactor Out Loud
Say what youâre cleaning and why. Reviewers will thank you.
10. Celebrate Cleanups
A great refactor deserves a high five. Or at least a GIF in the Slack thread.
đ§ Starter Kit: Hygiene Practices You Can Adopt Today
đ§ Remember: Hygiene â Perfection
This isnât about âperfectâ code. Itâs about continuously cared-for code. The goal is not to rewrite everythingâit’s to keep the system in a perpetually healthier state than yesterday.
đ„ A Call to Teams
Letâs normalize a culture where:
- Hygiene commits are praised.
- Cleanups are part of every sprint.
- Refactoring is routine, not rare.
- New team members inherit clean baselines, not messes.
đ§ Your Hygiene-Driven Workflow
1. Start feature branch 2. Refactor (if needed) â Commit: âchore: hygiene pass before featureâ 3. Implement feature â Commit: âfeat: implement user avatar uploadâ 4. Final hygiene sweep â Commit: âchore: tighten API naming & remove unused importsâ 5. Submit PR â Include hygiene summary
đ§Œ Make It a Habit, Not a Project
Because the best time to refactor was yesterday. The second best time is every day.
