Documenting lessons, failures, and insights gained through building, learning, and solving complex problems

I’m the actual human who made every single one of these videos they keep gluing together without asking. They love calling me ‘ex-Google engineer’ or ‘this guy’. Follow this guy and let’s actually chat. Original post is right here: xitter.cf/shenseanchen/status/20… Want the real AI Agent Harness System (Loop + Memory + Eval) instead of the mash-up? Grab my open-source Waku Agent (almost 1k stars): GitHub.com/shenseanchen/waku… Original YouTube channel: yt.seanchen.io (Better for your eyes. Trust me:)))) I also run a community where I host live biweekly Q&As and share all the original system-design files: whop.com/sean-ai-community-d… @X @elonmusk @benjitaylor @singhai @dinkin_flickaa please fix the theft on X. @vattybear thanks so much for the constant support my friend! 🔥
THIS GUY MAKES COMPLEX AI AGENT CONCEPTS RIDICULOUSLY EASY TO UNDERSTAND. No jargon wall. No assuming you already know what a reward model or an evaluation harness is. Just a straight line from "I have no idea how agents actually work" to "oh, that's genuinely simple." The best explainers do not simplify by cutting corners. They simplify by finding the one analogy that makes the whole thing click.

MiniMax (official)

$0.07 for M3, $3.39 for Opus. Both caught 13 of 17 bugs. Really interesting breakdown from @kilocode Definitely worth the read
We gave the same code audit to Claude Opus 4.8 and MiniMax M3. Same codebase. Same prompt. 17 known bugs planted in advance. MiniMax M3 caught 13 of them for $0.07. The cheapest Claude run caught the same 13 for $1.30. Here's the breakdown. 🧵

You already have auth working in your Expo app. Clerk 3.1 is about what it looks like. AuthView, UserButton, and UserProfileView — native components built on SwiftUI and Jetpack Compose. The part your users actually see, rebuilt from the platform up.

We've changed the trigger word from "workflow" to "ultracode". You can still say "use a workflow for this", but when you're clearly referring to something else, Claude won't kick off a dynamic workflow. For an explicit trigger, use "ultracode". We appreciate the feedback!

New in Claude Code (research preview): dynamic workflows. Claude writes an orchestration script on the fly, then spins up a large fleet of coordinated subagents in parallel to take on your most complex tasks. Use the word "workflow" in a prompt to get started.
