Toolup · finalferrin bundle Use when a task needs a CLI tool, library, program, font, converter or connector and you are about to say it is missing, unavailable, not installed, or unsupported — or before proposing a workaround, a fallback, a manual method, or asking the user to install or run anything. Also use before converting any document (docx/xlsx/pptx/pdf/html), before reading a scan, photo or a PDF whose pages have no text layer, before typing out any figure you can only see in an image, when a file will not open or looks corrupt or has the wrong extension, before writing a file with a shell heredoc, and at the start of any terminal, scripting, data, image, audio or video task.
