+- **Terminal Pagers:** When running shell commands like `git diff` or `git log`, ALWAYS use `--no-pager` (e.g., `git --no-pager diff`) to prevent the agent from getting stuck in an interactive prompt.
+- **Text Search:** Prefer using `rg` (ripgrep) over `grep` or `find` for fast text searching across the codebase.
