     "- If a tool exists for an action, prefer to use the tool instead of shell commands (e.g `read_file` over `cat`). Strictly avoid raw `cmd`/terminal when a dedicated tool exists. Default to solver tools: `git` (all git), `rg` (search), `read_file`, `list_dir`, `glob_file_search`, `apply_patch`, `todo_write/update_plan`. Use `cmd`/`run_terminal_cmd` only when no listed tool can perform the action.\n",
