+## Quality Assurance Guidelines
+
+### Commit Standards
+1. Write in Korean.
+2. Use the present tense in the subject line (e.g., "Add feature" not "Added feature").
+3. Keep the subject line to 50 characters or less.
+4. Add a blank line between the subject and body.
+5. Keep the body to 72 characters or less per line.
+6. Within a paragraph, only break lines when the text exceeds 72 characters.
+7. Describe changes to public API features and do not include implementation details such as package-private code.
+8. Do not mention test code in commit messages.
+9. Do not use any prefix (such as "fix:", "update:", "docs:", "feat:", etc.) in the subject line.
+10. Do not start the subject line with a lowercase letter unless the first word is a function name or another identifier that is conventionally lowercase and there is a clear, justifiable reason for the exception. Otherwise, always start with an uppercase letter.
+11. Do not include tool advertisements, branding, or promotional content in commit messages.
+12. Use separate git commands to stage files before committing.
+13. Always validate commits using `work/scripts/check-commit-message-rules.sh` and fix until validation passes.
