 *   **Test-Driven Development (TDD):** Wherever possible, Test-Driven Development principles should be followed. Write tests before writing the code they are intended to validate.
 *   **Pre-commit Hooks:** Ensure that `pre-commit` hooks are installed and active before making any commits. This can be done by running `pre-commit install` in your local repository.
+    *   **Note for Gemini:** Git commits trigger pre-commit hooks, which can take several seconds (or minutes) to complete. Checking the command status for git commit is only appropriate every 120s.
