Original Reddit post

Opus has just written a design doc. Opus can’t wait to start coding. Instead, ask: write a prompt for an adversarial reviewer. You’ll probably get a carefully considered prompt with excellent context you can paste straight into a fresh claude (or better yet, Codex/GPT 5.4) session. It’ll almost certainly find at least a few things that would’ve cost you much more time later. Half of them might even be right there in the prompt from your Opus design / plan agent. When I skip this, I nearly always come to regret it. submitted by /u/davblaster
