OP / Author here, I started closer to where you are but ended up realizing I've led a few eng teams and was never satisfied with code quality. What I COULD be satisfied by was moving our metrics in the right direction. Testing coverage, use cases covered by E2E / integration tests, P99/backend efficiency metrics, cost of infrastructure and obviously user growth along with positive feedback from Users.

That said, I don't "vibe" because it creates great code I love reading, but I can monitor and move the same metrics I would if I was managing a team.

I also use code tours a bit, and one of my first tools I needed and built (intraview.ai) was to support this need to get deep in the code the Agents were claiming was ready to ship.
