The vanilla setup
Boris Cherny, creator of Claude Code, says he no longer writes code at all, and his published setup is deliberately vanilla: Opus 4.5 thinking, five to ten parallel instances, plan mode, no permission-skipping, and one master tip, give Claude a way to verify its own work. The diary's reading: the anti-vibe-coding memes expired around February 2025, the framework peddlers are selling tuned cars, and the verify-your-work loop is life advice wearing an engineering hat.
// trace: where this idea came from
- ↳ video diary @ 27:39 (el creador de Claude Code ya no escribe código)
- ↳ video diary @ 38:52 (el tip final: un feedback loop para Claude)
- ↳ Entry 203-1: The empty shell (la última vez que Google y sus rivales se cruzaron acá)
Severo’s redesign shipped in an afternoon because Claude Opus 4.5 wrote it inside Antigravity ▸ 22:20, compiling the APK itself, reading its own error, fixing it, and recompiling before handing it over ▸ 29:48. His model ranking ignores the scoreboard: “vale mierda lo que dicen los benchmarks”, in reality Claude is simply better for programming ▸ 22:53. Which makes Antigravity itself the curiosity: a Google product offering its rival’s models ▸ 23:51, his theory being that Google, whose appetite for rivals’ assets the diary has covered before, pays for those tokens to learn, to improve its own models, and to fish users, because everyone knows Claude is the default for code ▸ 24:39. The confession rides along, reported here as said: when the low credit limit runs out he switches Google accounts and keeps going, “sorry por estar así todo pirata, pero es lo que tenemos” ▸ 25:08, with paying for Gemini deferred to better days.
The centerpiece is Boris Cherny, creator of Claude Code, saying he no longer writes code: 100% of it is now written by Claude Code ▸ 27:39. That dates the mockery: anti-vibe-coding memes were true up to about February 2025, he can confirm, he was there ▸ 29:10, the way thirty-finger jokes were true of early Midjourney ▸ 28:44; “Claude Opus marca un antes y un después” ▸ 29:32.
el mejor del mundo usa el setup más simple del mundo →
And the man’s setup is pointedly vanilla ▸ 31:21: Opus 4.5 thinking, slow but worth it ▸ 36:10, five to ten parallel instances ▸ 36:24 orchestrated through git so they don’t step on each other ▸ 36:45, always starting in plan mode ▸ 37:16, never skipping permissions, which the diary co-signs from experience: that’s how everything gets deleted ▸ 37:49. Against that, the course-and-framework peddlers of his vibe-coding group are selling tuned cars, pure aesthetics ▸ 32:37; jump in the water first ▸ 34:30 and build your own base before comparing methodologies ▸ 35:22. Cherny’s final tip, give Claude a way to verify its work and quality multiplies ▸ 38:52, gets immediately generalized at Julia: build, show, learn, refine, the feedback loop is also how a life improves ▸ 39:27…
