I spec out everything in excruciating detail with spec docs. Then I actually read them. Finally, we create granular tasks called "beads" (see https://github.com/steveyegge/beads). The beads allows us to create epics/tasks/subtasks and associated dependency structure down to a granular bead, and then the agents pull a "bead" to implement. So, mostly we're either creating spec docs and creating beads or implementing, quality checking, and testing the code created from an agent implementing a bead. I can say this produces better code than I could write after 10yrs of focused daily coding myself. However, I don't think "vibe coders" that have never truly learned to code, have any realistic chance of creating decent code in a large complex code base that requires a complex backend schema to be built. They can only build relatively trivial apps. But, I do believe what I am building is as solid as if I had a millions of dollars of staff doing it with me.
