Git quality practices
Keep history useful through atomic commits, good commit messages, release tags, and review-friendly change structure.
Git quality practices make history useful after the merge. Atomic commits, clear messages, and release tags turn repository history into operational documentation for reviews, incidents, audits, and releases.
Subtopics: atomic commits, good commit messages, release tags.
On interviews: why history quality matters, how to split changes, what a good message contains, how tags support release traceability.
Common pitfalls: vague commits; overly strict rules that slow teams without benefit; mutable release tags.
The trade-off is history discipline versus flow — optimize for future maintainers and incident response.
Checklist:
- Split logical changes at commit time.
- Explain intent in messages.
- Treat published release tags as immutable anchors.
- Connect tags to artifacts and changelogs.
