KARPATHY JUST HANDED EVERY DEVELOPER THE EXACT FILE CLAUDE CODE NEEDED FROM DAY ONE.
65 lines. 110K stars. the cheat code for every broken workflow you've been blaming on the model.
if I had this a year ago, I would've shipped twice as fast.
make sure to bookmark it before it gets lost in your feed.
I was losing 2 hours a day to Claude rewriting code I didn't ask it to touch.
then I found CLAUDE. md.
90 seconds to set up. changed everything.
Karpathy identified 4 failure patterns Claude Code repeats constantly, in his own words:
→ silent assumptions: Claude makes decisions without checking with you
→ code bloat: 1000 lines written when 100 would do
→ collateral damage: Claude edits code unrelated to the task
→ no success criteria: Claude loops with no finish line
these aren't model failures. they're missing instructions.
CLAUDE. md gives Claude the 4 rules it needed from day one:
→ think before coding, state assumptions. ask before assuming.
→ simplicity first, minimum code. nothing speculative.
→ surgical changes, touch only what is required. nothing adjacent.
→ goal-driven execution, define success before starting. loop until verified.
65 lines. no build step. no framework. no dependencies.
just the 4 principles every developer already knew, but needed Karpathy to write down.
ClaudeKit is the only team you need to build something like this (https://t.co/aW94IVKzGN)

the labor market is not ready for what codex is becoming
today i gave codex an api key and it:
> pulled 100k rows
> figured out the endpoints
> cleaned the data
> answered questions that would’ve taken a $250k data scientist 2-3 business days
> sanity checked it
it did this in 2-3 minutes
btw these were not simple sql queries
messy questions where it was unclear what formula to use, what data was missing, and how to iterate based on prior experience working directly with me
could see the unhobbling, CoT, and mechanistic interpretability all working in tandem
absolutely fantastic
2026 is incredible
With @framer Agents, I designed, built, launched and packaged one of my largest templates, as part of the 24hr Hackathon ⏰
In just 24 hours, using Agents and connecting Claude Code, I built Selene, a template built for AI SAAS companies.
🔗 Link to submission below
@Teknium Ok you win on the timeline, however. you have whole teams and endless tokens
I have me and a couple tokens. i didnt even know what Agentic AI was 2 months ago. and i built mine on 26b and 120b models with zero coding experience
Soooo, i win by default haha
THIS GUY AUTOMATES HIS ENTIRE YOUTUBE WORKFLOW BY TALKING TO CLAUDE. IT BUILDS THE FULL N8N PIPELINE FOR HIM, NODE BY NODE, FROM ONE PLAIN-ENGLISH PROMPT
Building automation in n8n normally means dragging nodes, wiring them by hand, and editing JSON for hours. With one MCP connection, Claude does all of that for you, you describe the YouTube workflow you want, and it builds it inside n8n node by node.
Here's the setup:
1. Install the n8n-MCP server. Search "n8n-mcp czlonkowski" on GitHub. Clone it, then run npm install, npm run build. (There's also a one-line Docker option in the readme if you'd rather skip the build.)
2. Connect it to Claude. Add the MCP server to your Claude config (the readme gives you the exact block to paste). Restart Claude. Now it has full knowledge of every n8n node, 1,800+ of them, including the AI ones
3. Point it at your n8n. Add your n8n instance URL and API key so Claude can build directly into your account, not just describe workflows
4. Describe the automation. In Claude, just say what you want in plain English. Something like: "Build an n8n workflow that takes a topic, generates a script, sends it to ElevenLabs for voiceover, assembles a video, and uploads it to YouTube on a schedule with title and description filled in."
5. Let Claude build and validate. It searches existing templates first, pulls the exact node docs, wires the workflow, and validates it, catching its own mistakes before handing it back. What took an afternoon of node-dragging is done in minutes
Then you open n8n and your workflow is sitting there, built and ready. Tweak the parts only you care about and switch it on
One honest note: this builds the machine, not the magic. The automation handles the repetitive pipeline, the script, the voiceover, the upload, the scheduling. What still decides whether the channel works is the idea and the quality you point it at

Claude Code is changing how software gets built in 2026.
Not gradually. All at once.
THE GOOD:
✅ Reads your ENTIRE project (not just the open file)
✅ Generates + runs + fixes errors in one session
✅ One dev refactored 40 files, 28 bugs — single session
✅ Lives in terminal + VS Code + JetBrains
✅ One developer alone = what used to take a whole team
THE BAD (nobody talks about this):
❌ No free tier. You're paying from day one
❌ Pro plan ($20/mo) burns out fast on heavy sessions
❌ Learning curve is real — it lives in the terminal
❌ AI-generated code still needs human review. Always.
Not magic. It's a tool. You gotta know how to use it.
WHAT CHANGES FOREVER:
The question isn't "Can you code?" anymore.
It's "Can you tell the AI what to build?"
In 2026 those are NOT the same thing.
The dev who gets system design + uses Claude Code
= the team that used to cost $50K/month
Are you learning to be that developer?
Or are you still coding line by line?
🚨 This AI Agent generated $57,340 for one of my clients.
✅ 1,248 tasks completed
✅ 312 hours saved
✅ Runs 24/7
Most businesses are still hiring people for work AI can already do.
