When I use amazon-q for this, I make it write a plan into a markdown file, then I clear context and tell it to read that file and execute that plan phase by phase. This is with Sonnet 4. Sometimes I also yeet that file to Codex and see which implementation is better. Clear context, read that file again, give it a diff that codex produce and tell it do a review.
