I use code2prompt (https://github.com/mufeedvh/code2prompt) with the following zsh wrapper:

  function code2prompt() {

    # wrap the code2prompt command in a function that sets a number of default excludes
    # https://github.com/mufeedvh/code2prompt/

    local arguments excludeFiles excludeFolders templatesFolder excludeExtensions
    
    templatesFolder="${HOME}/git/code2prompt/templates"
