I'm currently working on a combined Aero sim/CAD/CAM software for designing, simulating, and performing DFM optimization specifically for Group 1 to 3 winged UAVs.

What I do is ask Opus/Gemini to explain the parts I don't understand. And I do some of my own research to verify accuracy of the explanations.

In addition:

* Every new feature has a Feature Design document which I review, modify, and approve. And a corresponding Implementation Plan which I also review and approve.

* Every fix has a RCA document and fix Implementation Doc which I review, modify, and approve.

* There's a global high level Architecture and Design document with additional sub component design documents which are always kept in synch after a new feature or bug fix is done. Synching it is always a step in the Implementation plan.

This does adds some overhead but it allows me to have have check point gates. This has often allowed me to catch misunderstandings and align properly before any code gets edited by the AI agent.

Having the above docs also helps when it comes to referencing them as context to properly ground new features or bug fixes.
