Changing the command line usually involves changing an environment variable in your shell. Since processes can't change each others' environment variables directly, you can't change a prompt from another process.
What I'd recommend is having the tool wrapper write a status line to a file, then using shell-escapes to insert a `cat /whatever/the/file/is` into your prompt. See your shell documentation for details.
