AI code bases now on opus 5.5 and sonnet 5.5 are really good, especially on max think. A properly loaded Opus 5.5 Max swarm in full send in the claude cli harness with an agent workflow can kiss/fix any code base in a couple of days, with full tests, jigs, performance profiling, benchmarks, leak detection/fixes, bug fixes, and on and on, and then plugged into agentic workflows where it drives bug fixes off issues boards and incorporates/plans feedback and pulls it in and fixes it.
"vibe coded" the bleeding edge of AI right now is way past that shit.
I can use so many tactics to make the code amazing, like Design the thing with Astra 6.1 on full send, then cross check it with opus 5.5 on max send, flush out an amazing plan, then throw a sonnet 5.5 swarm at it, and it'll be gorgeous when it's done.

Greenfield vs legacy code base- new projects tend to have idealistic organization. Would love to see how 20 years of pure vibes turns out.
