You don't make a good skill by writing a skill. You make it by doing the thing, fixing it 20 times, then telling the AI to bottle up everything you just did.

A viral product has a founder people can see and hear People buy from people. A screen recording from the founder beats a corporate promo video or a wall of features. Show your face.

We talk a lot about how important it is to set up self-verification loops. Especially in the age of powerful models that can run for long periods of time, self-verification is a key ingredient that enables the model to run for much longer, delivering a result that is closer to what you intended, so you can do more without having to constantly check in on Claude as it works. @delba_oliveira gives a great breakdown of what that looks like and why it matters
How do you get Claude Code to check its own work before handing it back? Watch how you can encode your manual checks so Claude closes its own feedback loop:

RT @levelsio: I think the challenge is that everyone can now build apps But 1) almost nobody has distribution (like an audience), or 2)…

Virtually nobody is pricing in what's coming in AI. I wrote an essay series on the AGI strategic picture: from the trendlines in deep learning and counting the OOMs, to the international situation and The Project. SITUATIONAL AWARENESS: The Decade Ahead

Almost every AI power user I know is MORE stressed and busier after using AI, not less What people thought AI would do: 10x productivity so that we can finish work earlier & relax more What it’s actually doing: 10x productivity so that we end up with 20x more things to do cos of the sheer possibilities

As someone who builds institutional level quant systems for prediction markets, this is the closest thing to a quant desk simulation I have ever seen publicly shared. Runnable code for every model. Read it before someone takes it down.

Everyone is talking about the death of consumer apps in the vibe coding era. But at @a16z, I see B2C AI startups growing and retaining users better than every before. My takeaways on how consumer founders succeed in the AI era 👇

We just went from horse-and-carriage to car. The old manuals still have truth in them, but the whole map of effort, speed, and leverage changed overnight. Building used to mean holding an entire system in your head. A fragile memory palace. A house of cards in biological primate RAM. If you stop, the palace collapses. Dinner, a meeting, a context switch. You come back and it’s glass dust on the floor. That’s why builders can look “antisocial.” It’s not vibes. It’s survival. You’re trying to get the palace out of your head and into code before it evaporates. Then the weird miracle: I type a few paragraphs that barely make sense on reread, and the machine builds the palace anyway. It mirrors the structure. It fills the gaps. It hands it back. The feeling is not “wow productivity.” The feeling is: I am seen. Like the part of you that has been translating yourself for 20 years finally gets understood on first contact. This is why the new skill is not “code faster.” It’s taste, direction, and leadership. Managing a swarm of agents. Running tight loops. Knowing what to ask for. And it brings back something old-school: apprenticeship. We forgot how to teach. Now teaching matters again, because the tools are insane but the mind behind them still has to be trained.

how to use obsidian claude code to build a 24/7 personal operating system and build your startup: 1. write everything in markdown (daily notes, projects, beliefs, people, meetings) 2. link your notes together so they mirror how your brain actually thinks. 3. install obsidian cli so claude code can read your entire vault the relationships. 4. stop reexplaining projects every session. use reference files instead. 5. build custom slash commands: /context → load your full life work state /trace → see how an idea evolved over months /connect → bridge two domains you’ve been circling /ideas → generate startup ideas from your vault /graduate → promote daily thoughts into real assets 6. keep a strict rule: human writes the vault. agents read it, suggest, execute. 7. let claude aka clode surface patterns you’ve been unconsciously circling for years. 8. delegate from inside your notes. one sentence in obsidian → agent handles the rest. 9. treat writing as leverage.the more you write, the more context your agents have. 10. understand this:markdown files are the oxygen of llms. i really enjoyed seeing how to use obsidian thanks to @internetvin vin uses ai like a thinking partner wired into his life’s work. 99.99% of people won’t do this because it requires reflection setup. but once the vault exists, the agent stops being generic. it starts thinking in your voice. episode is live on @startupideaspod (more there) this one is different. send this tweet to a friend. im still processing how game changer obsidian claude code is, maybe you too watch

Apple will either acquire this or sherlock it within 18 months. They can’t let a third party own the fastest path from idea to App Store. Rork just abandoned their entire React Native stack for native Swift. This company raised $2.8M from a16z building cross-platform apps from prompts. Rork Max throws that away and bets everything on Apple-native. That’s a complete technical pivot, not an iteration. The “replaces Xcode” line is the real announcement. Xcode is a 21-year-old IDE that Apple has zero competitive pressure to modernize. Every iOS developer complains about it. Nobody builds against it because Apple controls the entire toolchain from compiler to App Store submission. Rork is betting that Claude Code can generate Swift well enough to bypass that monopoly entirely. The timing tells you something. They chose Claude Code and Opus 4.6 over GPT-5, which means they tested both and Anthropic’s code generation won for native Swift output. That’s a live benchmark result disguised as a partnership announcement. If Rork Max can actually one-shot native Swift apps for iPhone, Watch, iPad, TV, and Vision Pro from a browser, the IDE, the build system, the simulator, the provisioning profiles… all of that complexity collapses into a website. There are 34 million registered Apple developers. Most of them hate Xcode. Rork just showed them the exit, and Apple can’t afford to let someone else own the door.

Now that I've been through being a kid, growing up, and then having kids, it's clear that the main thing that differentiates people is simply whether they make an effort. Whether they're content to drift along with the current, or whether they try to swim.
