+## Git Workflow
+
+### Committing Completed Work
+
+Every completed job or feature must be committed to the git repository.
+
+When preparing git commits, always use the `conventional-commit` skill to create proper commit messages following conventional commit conventions.
+
+This ensures:
+- Clean git history with proper commit message formatting
+- No work is left uncommitted
+- Consistent commit message style across the project
+
+### Advanced Git Operations
+
+For advanced Git workflows (rebasing, cherry-picking, bisect, worktrees, reflog, history recovery), use the `git-advanced-workflows` skill.
+
+This skill provides:
+- Master advanced Git workflows including rebasing, cherry-picking, bisect, worktrees, and reflog
+- Maintain clean history and recover from any situation
+- Manage complex Git histories, collaborate on feature branches, or troubleshoot repository issues
+
