I've had a really terrible experience with codex so far. It tries to code by issuing patches. The problem is the patches are always wrong, so they never apply. It just spins and spins and spins and spins... AND you have to press 'y' for every. single. little. diff. Patch fails. Missing the right directory structure. Create the directory. Approve the patch again. Maybe it succeeds. Next tile. Approve patch. Patch fails. Missing the right directory structure. Create the directory. Approve the patch again. Again. Again.
