【断定】Claude Codeの真の価値は「指示の仕方」にある。
Y Combinator CEOのGarry Tanが実践する「5つの自作モード」が非常に示唆に富んでいます。
① /plan-ceo-review → 要件を根本から問い直す
② /plan-eng-review → 設計を深く詰める
③ /review → 致命的バグを洗い出す
④ /ship → テストからPRまで自動化
⑤ /browse → ブラウザで最終確認
単にコードを書かせるのではなく、AIに明確な役割を与えて工程を分断するという発想です。
私の視点：
これは単なる便利なプロンプト集ではありません。
AIエージェントを「道具」から「高度に専門分化したチームメンバー」に昇華させる方法論です。
日本の開発現場でも、このような構造化されたワークフローを導入すれば、生産性とコード品質が劇的に向上する可能性があります。
AIの活用レベルが「個人の技量」から「組織の仕組み」に移行する、重要な転換点と言えるでしょう。

Here's a common trap with AI if you're not careful:
1. You ask it to generate some markdown files (maybe to build some skills). You skim them and they look ok. Sure, there's a bit of slop in there, but you're too lazy to edit them manually.
2. Over time you ask it to generate more markdown files. Except now it's referencing the previous files to write the new ones.
3. What started as 5% slop becomes 10% and then more. Before you know it, you've got a pile of AI-generated slop that feels overwhelming and have no idea how any of it actually works.

Forget about simple chatbots that’s yesterday's news. We’re entering the era of personal systems that actually grow with you.
Garry Tan just open-sourced his entire AI OS stack. The most underrated part? The Skillify meta-skill. Instead of repeating manual tasks, he’s teaching the system to extract patterns and write its own "skill files."
100k pages of context + 100 automatic cron jobs = an AI that prepares for meetings better than a human assistant could.

This is the most complete setup I've seen yet to turn Claude Code into your personal OS.
Here's my new episode with @moritzkremb where he shared the system that runs his email, content, and even grocery shopping.
We talked about:
→ The 4 layers: folders, tools, skills, routines
→ Memory: Set up a nightly "dreaming" job
→ Tools: The best CLIs and MCPs to use
→ Skills: Video edits, planning, and more
→ Routines: When to use local vs. remote

The source of the myth is @_KarenHao she wrote a book called Empire of AI claiming a data center would use over 1,000x more water than a nearby city because she misunderstood the units of measurement.
It made international headlines and the mistake / lie has been unstoppable.

France is the only European country that turned nuclear generation into a structural competitive advantage. 57 reactors built between the 1970s and 1990s produce 70% of its electricity today. Wholesale power in France is currently around €52/MWh. In Germany, it runs €30-40/MWh higher. France is also the world's largest net exporter of electricity.

The best AI builders set up systems to help them ship faster.
Here's @moritzkremb's system to create short videos that saves him 10 hours a week:
1. Cron jobs scrape ideas from X and YouTube
2. AI generates rough notes for the script
3. Moritz then iterates with AI on the notes
4. He reads the script into his phone (no AI!)
5. He then uses Postiz CLI to auto-post to YT, IG, TikTok at the same time
📌 Watch him talk more about it here: https://youtu.be/ACRd0Ikg_KI?si=N50M5GQ6WqNdUHQJ&t=1910

My friend @finbarr says: It's like code as memory. You work with your agent in a non deterministic way to figure out how to execute a task. The first time it does a bunch of research and writes a script and then executes the script. Every future time it faces the same task it just executes the script immediately.
The future is already here, it just might not be in your hands unless you decide to build it.

Some personal news: I’ve started a company. It’s called Pops, and I’m excited to share that it’s backed by YC and part of the P26 batch.
Pops is what I believe to be the future of entertainment: AI-native, playful, social experiences and games anyone can create, remix, and play with their friends. Short-form software.
Huge thanks to @Suhail for being an early believer and supporter, and thank you to @garrytan, @greybaker and the YC community for your incredible guidance, support and belief in me — I'm just getting started

Republicans: Dems hate police.
Democrats: Women should have the right to choose.
Republicans: Dems want to kill babies.

Republicans: Dems want open borders.

Chris: Codex made me money without me doing anything..
Huge turning point for me today, I asked Codex to go off and make me $5. It went out, found a small open-source security/audit bounty path, made a legit PR, followed up with the maintainer, kept my payment details private -
This is cool
Nainsi Dwivedi: “I don’t think I’ve typed a line of code since December.”
When Andrej Karpathy said that, most people treated it like a crazy AI quote.
@garrytan treated it like a question:
“What happens when one person operates like an entire software team?”
Then he built gstack.
And
I literally went through this today. OpenClaw messed up its own PATH and I spent the morning going into the guts of Dockerfiles and using Claude code to remove the bug... but then I was flying again by afternoon.

“People have an overwhelming bias to just do the thing they feel like they’re supposed to do.”
“[As a founder], it’s your job to look inside your mental dictionary of language and identify 500 to 1000 words in the right order that are going to jailbreak people and reprogram them to come and join you off the path.”
“It’s very doable. It’s been done to convince an entire nation to continue fighting a war. It’s been done to convince racists to consider the possibility of allowing civil rights. It’s been done to inspire a nation to go to the moon.”
“These things, we’ve seen them, we just don’t really recognize them for what they are, which is packaging 1000 words in the right order, in combination with the right curation, and delivering them such that they jailbreak people at scale.” @lulumeservey
