I use Claude with the Codex plugin as a critic (sometimes I switch and manually review with Claude). With the Superpowers skill (which I am trying to get rid of), it designs expensive models and implementations, uses cheaper ones for other, less important stuff, including Haiku, sometimes upgrading if it hits a roadblock, and then, finally, reviews with expensive ones. Why would I need Composer unless I'm a poor hobbyist? I care about value created, not about the affordable costs. So far, Claude and Codex have given me a huge ROI and are worth every penny. I don't even use an IDE, although I pay for Zed, or the terminal anymore - Claude and ChatGPT desktop apps give me everything and keep things simple. I just watched Theo yesterday [0], and I realized I'm not alone.
