Claude Code Project Structure: The Complete Map

People think learning Claude takes days. It doesn't. I wrote 17 free guides that teach it in hours: Claude 101: ruben.substack.com/p/claude-for-d… Claude Code: ruben.substack.com/p/the-claude-c… Claude Skills: ruben.substack.com/p/claude-skills Claude Design: ruben.substack.com/p/claude-design Claude for Excel: ruben.substack.com/p/how-to-make-… How to Prompt: ruben.substack.com/p/prompt-47 Claude + Linkedin: ruben.substack.com/p/claude-linke… Be good at Claude: ruben.substack.com/p/s Stop writing like AI: ruben.substack.com/p/its-not-x-it… Claude Certificates: ruben.substack.com/p/im-claude-ce… Claude for your team: ruben.substack.com/p/claude-for-t… Claude Connectors: ruben.substack.com/p/claude-conne… Set up Claude Cowork: ruben.substack.com/p/claude-cowor… Stop Prompting Claude: ruben.substack.com/p/stop-prompti… Claude to sound like you: ruben.substack.com/p/youre-just-a… Stop hitting Claude limits: ruben.substack.com/p/how-to-stop-… Stop using Claude at work: ruben.substack.com/p/how-to-use-y… ___ PS: I'm Ruben Hassid, and I want us to master AI before it masters us, with simple instructions.

🚨BREAKING: PEOPLE KNOW WHEN YOU'RE USING CHATGPT AND CLAUDE. The structure, the tone, the excessive polish. It all gives you away. 7 prompts that fix this:

@_david_brg Ich bin aktuell selbst vor Ort und kann das zu 100 Prozent bestätigen.

Ich bin dieses Wochenende in Stettin, Polen. 🇵🇱 Migrationsquote: Nur rund 0,2 Migranten pro 1.000 Einwohner. Man sieht sofort den Unterschied: Ein Land, das seine Grenzen schützt und seine Identität bewahrt. Deutschland 🇩🇪 sollte endlich aufwachen und sich ein Beispiel nehmen.

Founders spend $200,000 relocating to San Francisco hoping to get close to Paul Graham. He just flew to Stockholm and gave you 22 minutes for FREE. Founder of YC, $600 billion portfolio, the most powerful man in startups. The article below, my 25 prompts that put you 10x ahead from anywhere.

Claude Code isn't a coding tool. (It's a programmable dev environment) Engineers open it, type a prompt, and let it write code. But the real leverage is in the system around the prompt. Here are 12 features that make Claude Code programmable: 𝟭) 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱: The project's persistent memory. Stack details, conventions, and constraints load automatically at every session start. 𝟮) 𝗥𝘂𝗹𝗲𝘀: Behavioral guardrails beyond 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱. Project-wide do's and don'ts that apply across sessions and contributors. 𝟯) 𝗦𝗸𝗶𝗹𝗹𝘀: Reusable instruction files stored in .claude/skills/. Write once, and Claude follows them automatically every time the task matches. 𝟰) 𝗛𝗼𝗼𝗸𝘀: Shell scripts that fire on events like PreToolUse and PostToolUse. Auto-lint, run tests, or validate output without manual intervention. 𝟱) 𝗦𝗹𝗮𝘀𝗵 𝗖𝗼𝗺𝗺𝗮𝗻𝗱𝘀: Workflow shortcuts stored in .claude/commands/. Multi-step flows triggered with a single keystroke. 𝟲) 𝗣𝗹𝘂𝗴𝗶𝗻𝘀: Bundles of skills, hooks, commands, and MCP servers packaged into one installable unit. Over 100 official plugins are in the marketplace today. 𝟳) 𝗠𝗖𝗣: Connects Claude to databases, APIs, and external services. This is how it gets real-world access beyond the codebase. 𝟴) 𝗣𝗹𝗮𝗻 𝗠𝗼𝗱𝗲: Claude drafts a step-by-step plan before touching any code. Approve or reject before anything runs. 𝟵) 𝗣𝗲𝗿𝗺𝗶𝘀𝘀𝗶𝗼𝗻𝘀: Whitelist or block specific tools on a per-session basis. Non-negotiable for anything production-facing. 𝟭𝟬) 𝗦𝘂𝗯𝗮𝗴𝗲𝗻𝘁𝘀: Spawn parallel Claude instances that divide and conquer multi-step workflows simultaneously. 𝟭𝟭) 𝗩𝗼𝗶𝗰𝗲 𝗠𝗼𝗱𝗲: Talk to Claude hands-free via /voice. Push-to-talk with the spacebar, and the command goes straight to the input field. 𝟭𝟮) 𝗥𝗲𝘄𝗶𝗻𝗱: Step back to any checkpoint in the session and restart cleanly from that point. Features 1-5 define the environment. 6-7 extend it. 8-9 control it. 10-12 change how it runs. That framing matters because the gap between using Claude Code as a chatbot and using it as a programmable system is enormous. 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱 + Skills + Hooks alone can automate half the repetitive decisions in a codebase. If you want to go deeper, I wrote a detailed article covering the anatomy of the .claude/ folder, a complete guide to 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱, hooks, skills, subagents, and permissions, and how to set them all up properly. The article is quoted below.

@satoshiNa21 @NoaMagid Wer behauptet es?

@NoaMagid @the_code_doctor da schau an die friedlichen Palis 🤦‍♂️

This is what Hamas did to Israeli Muslim civilians on October 7.

@Vervielfacher1 @MitAktien Die Billion ist bei einer 7% Beteiligung bereits vollständig im aktuellen Aktienpreis berücksichtigt. Leider zu spät.

@MitAktien $SMT Scottish Mortgage Investment Trust wäre vielleicht auch ein Blick wert. SpaceX gehört zu den Top Positionen, das IPO könnte deutliche Auswirkungen auf den NAV haben.

Minimum eine halbe Mio werde ich in den Spacex IPO investieren, eventuell auch mehr! Es ist einfach die heftigste Firma der Welt. Optimal wäre natürlich, wenn die Börsenstimmung zum IPO nicht all zu optimistisch ist, und die Bewertung unter 1,5 Bio Dollar bleibt. Frage ist, ob dann der IPO stattfindet. #moon-and-beyond" target="_blank" rel="nofollow noopener">spacex.com/updates#moon-a…

@SebastianG_De @luckysatoshi21 Sind es nicht 6.5 Prozent? Also eher 26.000? Aber auch extrem viel

Wenn ich ein Haus in NRW für ~400.000€ kaufen will, dann zahle ich fast 30.000€ Grunderwerbsteuer. Hat man euch eigentlich ins Gehirn geschissen? Die Steuer muss abgeschafft werden! 😠

@HeimatliebeDE Sogar im billigsten Sessel. Schaut euch Erdogan an. 😂😂😂

Deutschland (Merz) in der letzten Reihe. Mehr muss man nicht wissen.

@satoshiNa21 @AndreasFW888 @bitcoin_hotel Haha. Ja genau

@AndreasFW888 @bitcoin_hotel @the_code_doctor die Jacke die du meintest 🤣🤣🤣

Nach der Roadshow - erster Tag - und hier ist alles an Vitaminen und Spurenelementen drin, die ein junger Mann zum Heranwachsen braucht! ⁦@bitcoin_hotel⁩

@mine_eins @luckysatoshi21 @VR_BayernMitte Fand's auch richtig klasse.

Alles Macher!!! Die Zukunft ist jetzt! @VR_BayernMitte

@AdamBLiv Wie krank ist bitte das? OMG

Strategy vs. the top corporate treasuries over the next 20 years. BTC at a 35% CAGR vs. 8% USD debasement. Strategy is becoming a company of totally unparalleled financial strength.

@xLumin0x @TimKoffiziell Dito

@TimKoffiziell Ich war mein Leben lang Dortmund Fan! Das ist jetzt vorbei, Dauerkarte und Mitgliedschafft gekündigt! Und ich kenne viele die es mir gleich tun!

So einen Rotz postet man allen Ernstes einen Tag nach dem Attentat auf Charlie Kirk? Wie kaputt im Schädel muss man sein?! Tretet vor euren Ball und haltet euch aus der Politik raus! Da habt ihr eh keine Ahnung von.

@SC2Jira @donaldtusk It was not Ukraine that warned Poland. But what sense does it make that Belarus first warns Poland and then shoots down drones?

@SC2Jira @donaldtusk Either you didn’t listen to the interview, otherwise you wouldn’t be writing this here. Just for your information, the interview comes from Belarus, and Belarus had warned Poland beforehand and at the same time shot down drones.

Last night the Polish airspace was violated by a huge number of Russian drones. Those drones that posed a direct threat were shot down. I am in constant communication with the Secretary General of NATO and our allies.

@Uhlobaron1 @donaldtusk x.com/the_code_docto…

@the_code_doctor @donaldtusk Easy. They came via Belarus.

@SC2Jira @donaldtusk x.com/the_code_docto…

@the_code_doctor @donaldtusk They don't necessarily fly through Ukraine, they could fly through Belarus for example.

@adrianadastra @donaldtusk Is that unnoticed? x.com/the_code_docto…

@the_code_doctor @donaldtusk How do drones fly unnoticed over Belarus ?
