I created a small wrapper around gh models run which was inspired by gh copilot suggest but written in plain bash/shell script and taking advantage of persisted system prompts (and a nice german term "dingens" 🇩🇪 - silent "h" 😀 )

alias dingen.sh='function _dingens() { bash -c "$(curl -fsSL https://dingen.sh/script)" -- "$@"; }; _dingens'
dingen.sh <system_prompt_file> [--max-tokens <number>] <user_prompt>
