+# Global Pi Instructions
+
+## Version Control
+
+Prefer Jujutsu (`jj`) over Git for source-control operations.
+
+- Use `jj status` instead of `git status`.
+- Use `jj diff` instead of `git diff`.
+- Use `jj log` instead of `git log`.
+- Use `jj describe` for change descriptions.
+- Use `jj new`, `jj split`, and `jj squash` for change management.
+- Avoid `git add`, `git commit`, and direct index/staging workflows unless explicitly requested.
+- Git commands are acceptable only for operations that `jj` cannot perform or when the user asks for Git specifically.
+- When reporting changes, mention the active `jj` change/workspace state rather than Git staging state.
