True, but I think people are also missing the trick behind markdowns that reference each other and are used for context window management. They go in your source control, they are reusable, extendable, and composable in the same way code is. So planning is not a one-off effort. It compounds over time. If you're doing it right your plan is referencing automation techniques - testing, CI/CD, etc. This further compounds so that the agents verify their own work against the standards that you set.

To be honest, the models are getting so good that they do most of this unprompted now.
