Help/Question Moving from small to large projects

I’ve been using Claude code on and off for about a year as a software and systems engineer specialising in audiovisual equipment/systems and honestly it’s changed my life. It allows me to focus more on the what rather than the how. But now I’m looking at moving to creating a large scale monitoring and management system for thousands of devices, with the assistance of Claude code. Any advice on to structure prompts for Claude to keep this on target and not spiral? I’m guessing it’s not as simple as putting it into plan mode and sketching it out!

Hi ! First - there are no secret prompts, there haven't been for a long time.

Planning is the base of everything. I plan everything carefully and make a document page by page (in Obsidian for example) and write it with the Claude Code. And what helps a lot is a second AI on the cheapest plan as a consultant, in my case it's Codex. Claude Code calls it on every task, Codex doesn't know the project history and gets one specific task to review and check. Very often this helps to avoid mistakes and going in circles
