Summary

The video presents 20 practical lessons for using Claude Code, from choosing an interface and setting up a project to checking results, saving reusable instructions, and connecting other tools. It emphasizes giving Claude a way to verify its work, using plan mode when a task is unclear, and keeping context and project notes manageable. More advanced workflows include skills, hooks, sub-agents, parallel sessions, cloud-based tasks, and scheduled jobs. It closes with seven common mistakes and recommends starting with one routine task.

Key points

Claude Code can inspect and edit files, run commands, and check whether the result meets the request.
It is available through the desktop app, terminal, code editors, the web, and a phone; the video recommends starting in the desktop app if the terminal feels intimidating.
Give each project its own folder and use /init to create a Claude.md file with persistent project context and rules.
For important work, ask Claude to verify its own output, such as by checking a phone-sized preview or comparing prices against a list.
Use plan mode for tasks that are not yet clear; for a job that can be described in one sentence, the video suggests letting auto mode run.
Manage context with /clear, /compact, and /context, and keep Claude.md short.
Turn repeated instructions into skills, and use hooks for actions that must happen every time.
MCP connectors can give Claude access to external tools and data, while sub-agents can research or review work independently.
Parallel sessions, work trees, web tasks, and scheduled jobs can extend Claude Code beyond a single chat session.
The video warns against giant chats, repeated corrections, overly long Claude.md files, unverified output, uncontrolled exploration, excessive effort settings, and having no backup.

Full transcript (original language)

00:00 Here’s a thousand hours of Claude code squeezed into 20 minutes and you don’t need to know how to code. >> When we first released Claude code, it was like a little video and I remember posting it to Slack and there was like two people that gave like that reaction. >> [laughter] >> Like people were like excited. That’s like a really nice way to say that it wasn’t really good. >> That was Claude code’s first demo inside Anthropic. Two reactions. Today, Anthropic says more than 80% of the code it merges was written by Claude.

00:32 And the people using it aren’t just engineers. >> I’ve never written a single line of code before in my life. I literally had to Google how do I [music] open terminal on Mac? >> Abracadabra. It’s kind of magical. I’m not an engineer. I’m non-technical. I don’t know how to code, but with Claude code, you don’t have to know how to code. >> So here’s the deal. 20 lessons in 20 minutes. What Anthropic’s own team says, plus what this channel learned the hard

01:03 way. By the end of this video, you’ll go from never opening Claude code to running a team of AI workers that keep going after you close your laptop. And stick around for lesson 16 where one of the people who built Claude code admits he stopped using the feature every tutorial tells you to use. Lesson one. Normal Claude chat gives you an answer and then you do the work.

01:33 Claude code does the work. It can open the files on your computer, create new ones, run them, and check that they actually work. >> Claude code is an agentic [music] coding tool that understands your code base, edits your files, run commands, and integrates with your existing developer [music] tools to help you get things done faster. >> Under the hood, it runs a simple loop. Look around, do something, check the result. If it isn’t right, go around again. >> Claude Code will then gather contacts

02:05 required to complete your prompt. Then, it takes action. Finally, it verifies those results and determines if they achieve what your prompt set out to do in the first place. And if they don’t, Claude goes back and runs the loop again until the results are complete and verifiable. >> That last step, checking its own work, is the whole secret. Hold on to it. It comes back in lesson six. And coding is just the start. People use it to rename and sort a thousand messy files, clean up a

02:36 spreadsheet, turn a pile of receipts into a report, or build the little tool they always wished existed. Remember the marketer who had to Google how to open the terminal? >> Now, this previously would have taken me maybe [music] 30 minutes. We’re able to do this process in around 30 seconds. So, the gap between I wish this existed and wow, I can actually build this myself is actually much smaller than people realize. >> Lesson two, Claude Code lives in five places.

03:07 The Claude desktop app, the terminal, code editors like VS Code, the web, and your phone. It’s the same Claude Code behind every door. If the black terminal screen scares you, start in the desktop app. Open the code tab, pick a folder, and type like you’re texting a smart friend. You also get this, a live preview of what it builds, and a clear before and after of every change.

03:38 Lesson three, the money. Claude Code isn’t on the free plan. It starts with Pro at $20 a month, or 17 if you pay yearly. Max is 100 or 200 for heavy users. Your usage resets every 5 hours, and there’s a weekly cap, too. Type {slash} usage anytime to see how much you have left and what’s eating it.

04:09 Lesson four, give every project its own folder. Ours is a small bike repair shop called Spoke & Chain. Open the folder and the first thing you type is {slash} init. Claude reads everything in there and writes itself a note called Claude.md. >> When you open up Claude Code without a Claude.md file, it’s like it has to start fresh every single time. It’s like an onboarding script for your codebase. >> Think of it as the note Claude reads at

04:41 the start of every session. So, you never explain your business twice. Ours says things like we’re closed Sundays, a basic tune-up is $65, and always write like a friendly local shop, never like a bank. Open it and edit it like any other note. It’s your rulebook. Lesson five, Claude Code now starts in auto mode. Before each action, a second model checks it and blocks anything risky. So, you aren’t clicking yes 200 times.

05:11 Anthropic found people approve almost every prompt anyway. >> In our research, 97% of emission prompts in Claude Code get approved. With probes in auto mode enabled, the attack success rate in our evaluations dropped to zero. >> One more control? Press shift and tab to cycle the modes. Ask me first, auto accept edits, or plan only.

05:44 Lesson six, and if you remember one thing, make it this one. Give Claude a way to check its own work. Anthropic puts it first in their best practices guide. Don’t just say build me a website. Say build it, then open it at phone size, take a screenshot, and make sure every price matches my price list. >> I remember with with Opus 4, Claude tested itself. And we we we just like hooked it up to Opus 4, and then I was like, Claude,

06:16 build the feature and then test yourself in like bash. And it opened a little Claude CLI and tested its own feature. And I was just like, woah. It’s crazy. >> Watch. It checked the phone view, caught a missing icon, fixed it, and checked again. That’s the difference between

06:46 babysitting an AI and walking away from one. >> So on a Friday night, I downloaded the tool that would become Claude Code. I was carrying around my laptop with me all weekend. Um but what I didn’t know is that the Claude Code team had built this internal like leaderboard. And over the weekend, I’d shot to the top. >> That’s hour 100. You can’t put it down. And this is exactly where most people pick up the bad habits. Here are the

07:16 five that separate the pros. >> If you take one thing away from Claude Code, let it be this workflow. Explore, plan, code, and commit. >> Lesson seven. For anything bigger than a quick fix, switch to plan mode first. Claude reads around, asks you questions, and writes a plan without touching a single file. You fix the plan, not the mess. >> And this re-here is the best place to course correct because it’s before any code is written.

07:57 >> Remember that feature? In lesson 16, its own creator says something surprising about it. Lesson eight. Claude going the wrong way? Press escape once and it stops, keeping the work so far. Press escape twice and you can rewind to any earlier message, code and all. One warning from Anthropic’s docs. This isn’t a real backup. For anything you care about, ask Claude to save a version with Git.

08:37 >> Context is Claude’s working memory. >> Lesson nine. Every message, every file it reads, fills up that memory. And as it fills, Claude gets worse. So, type {slash} clear when you switch to a new job. {slash} compact squeezes a long chat into a summary. And {slash} context shows you exactly what’s taking up the space. Got a quick side question? Start it with {slash} BTW and it won’t clutter the main job.

09:19 >> better. And a lot of people that I watch uh using Claude code just type make it better. Um make no mistakes. Yeah. Yeah, that’s not good prompting. >> Lesson 10. Make it better is not a prompt. Drag in a screenshot of a site you love, a photo of a sketch, or point at a file with the at sign. And for anything big, flip it around. Tell Claude to interview you first. It’s better at pulling out what you want than you are at explaining it.

09:58 Lesson 11. Claude can think harder or faster. /effort turns it up or down. And the word ultra think in a message gives you one extra deep answer without changing anything else. Higher effort burns your limit faster. So, keep the big brain for hard problems and let easy stuff run on medium. If this is useful, hit subscribe because it’s free. And if you want to back the work, hit join here or the supporter button on Facebook. Now, the part where it starts

10:30 working for you. >> If you told me I was going to be a go-to-market architect Anthropic a year ago, I would be pretty surprised. I don’t think I’ve ever had the technical chops to be in these conversations. I would say Claude is saving probably me at least two to three hours a day for answering emails. >> Two to three hours a day from someone who says he never had the technical chops. That doesn’t come from better prompts. It comes from teaching Claude once so it remembers forever.

11:01 Four lessons. >> Every single time Claude makes a mistake, I don’t tell Claude to do it differently. I tell it to write it to the Claude.md or to like make a skill or or something to do it differently. And if you can do this, then Claude can just like run forever. >> Lesson 12. The habit that compounds. When Claude gets something wrong, don’t just correct it. Tell it, “Add this to Claude.md so it never happens again.” Claude also keeps its own memory notes now automatically. One catch. Keep that file short.

11:32 Anthropic warns that if it’s too long, Claude ignores half of it. >> A skill is a markdown file that teaches Claude how to do something [music] once. If you find yourself explaining the same thing to Claude repeatedly, well, that’s a skill waiting to be written. >> Lesson 13.

12:02 A skill is a recipe. Claude follows the same way every time. You don’t even write it yourself. Just say, “Turn what we just did into a skill called quote now {slash} quote plus a customer’s message.” Gives you a repair quote in your exact format with your prices every time.

12:33 >> A lot of your contacts lives elsewhere like your databases, your productivity apps, or [music] in public repositories. This is where MCP comes [music] in. >> Lesson 14. Your real work lives in other apps, your calendar, your docs, your spreadsheets, your browser. Connectors called MCP plug those straight into Claude code. Notion, Google Drive, Slack, your database, even a real web browser. Once it’s connected, Claude can read from it and act on it the same way it works with your files.

13:03 >> You don’t need to know how to write SQL. You just need to be a human interpreter of that data and that result. >> Type {slash} MCP to see what’s connected. A browser connector, for example, lets Claude actually click through your site like a customer would. >> Hey. something needs to happen every time without fail, don’t put it at a

13:33 prompt. Put it in a hook. >> Lesson 15. Claude follows instructions most of the time. A hook makes something happen every single time. Ping my phone when you finish. Never touch the bookings file. Run the price check after every edit. Ask Claude to set the hookup for you. And slash hooks shows what’s running.

14:05 And when you want all of this pre-made slash plugin installs, bundles of skills, connectors, and hooks that other people built in one go. Here’s a quick story. We used Claude code and these same habits to build our own product. It’s called Make Viral Reels. Paste a link or pick a story going viral in your niche and you get a finished reel with voice, captions, and music. Your first one is free and the link is below. Now, the last stretch.

14:44 >> [sighs] >> Back in time, rewind back to 2013, I was, you know, writing all the code directly myself in our dorm room at Stanford. I kind of stopped coding. It wasn’t until I was using Claude code that I actually like was shipping production code in our code base again. So, I like had a major comeback. >> The last stretch is where one person starts working like a team. And it starts with the lesson I promised you. >> Okay, what they used to be is plan mode. I don’t use that anymore. I

15:14 >> What do you use instead? >> Auto mode. >> Auto mode? >> It’s the best. >> Instead of plan mode? >> Instead of plan mode. Yeah, cuz I The newer models, they don’t actually need like a planning step anymore. >> Lesson 16, the man who built Claude code barely uses plan mode anymore. Newer models plan in their head. So, here’s the rule after a thousand hours. If you can describe the job in one sentence, just say it and let auto mode run. If you can’t, plan first. Plan mode isn’t training wheels. It’s for jobs you

15:45 haven’t figured out yet. >> Well, without a sub agent, Claude might read 15 files, run several searches, and trace through multiple function calls. With a sub agent, you get the answer without the journey. >> Lesson 17, a sub agent is a helper. Claude with its own fresh memory. Say, use sub agents to research our three nearest competitors’ prices and

16:15 only the answers come back, so your main chat stays clean. My favorite trick from Anthropic big stocks. Before you call anything done, have a fresh sub agent review the work. It hasn’t seen the mess, so it spots what you both missed. Inside Anthropic, this is how a month-long job gets done in days. >> I had been working on our Q4 plans [music] and I was like, okay, we’re going to work on this suppression engine and this is going to take, you know, at [music] least one to two months. One of our new hires built it in a week.

17:06 >> And so, I know people at Anthropic and a few customers that run four Clauds at the same time. There’s I can only do two, but I know people that do four. >> Like, now I just have like armies of agents that are doing stuff. Like, I’m prompting one agent or have like an agent that’s like prompting agents that’s prompting agents and it’s like a tree of like thousands of agents. >> Lesson 18. From two Claude sessions to thousands in 1 year. You don’t need thousands. Start with two. The desktop app runs sessions side by side. And each one can work on its own copy of the

17:37 project called a work tree, so they never step on each other. Then try {slash} goal. Give it a finish line like every page works on a phone. And it keeps going until it’s true.

18:11 >> Watch this. I’m going to give Claude a task and I’m going to close my laptop. Then, I’m going to open the Claude app on my phone. Claude has kept working and now it has a question for me. >> Lesson 19. Start a job on the web version and it runs in the cloud even with your laptop shut. Your phone becomes the remote. >> And the thing that I would not have expected 6 months ago is probably half my engineering now I do on my phone. >> And I remember you responding and you’re like, “Yeah, I’m coding from my couch.”

18:43 >> And the newest door projects lets you add over one big goal. Claude splits it into tasks and runs a whole team on it. It’s in beta for pro and max with a wait list. >> Watch this. I’m going to bring down a large goal for Claude. I’m not going to think about creating sub agents, managing multiple sessions, or work trees. Instead, I’ll just ask. Claude has figured out how to break my goal into smaller tasks and assigned a team to work on them in parallel.

19:14 >> And so someone filed a bug for it and I was going to get it get to the bug that night. And as my Claude was working it said, wait a second, another Claude has already fixed this. And he said he has another routine that just looks for bug reports that haven’t been responded to in 5 hours and puts up a fix. >> Lesson 20, the last one. Another Claude had already fixed it. That’s a scheduled task. Type /schedule and give it a job and a time. Here’s ours. Every Monday at 8:00 read last week’s bookings and send me a one-page summary.

19:46 That’s the moment Claude code stops being a tool you use and becomes a worker that shows up. Now the seven mistakes that cost us the most hours, fast.

20:16 One, one giant chat for everything. Clear between jobs. Two, correcting it over and over. Anthropic says after two failed corrections, start fresh with a better prompt. Three, a Claude.md that reads like a novel. Prune it. Four, trusting without checking. If you can’t verify it, don’t ship it. Five, letting it explore forever. Give it a scope or send it a subagent. Six, max effort on everything. You’ll hit your limit by lunch. And seven, no backup. Checkpoints

20:46 are not Git. That’s 1,000 hours in 20 lessons. Two reactions on a Slack post became a tool that lawyers, marketers, and co-founders use every day. >> Claude Claude has >> [music] >> helped me dream bigger. I felt I was always limited by what [music] programming languages I’m proficient at. >> Don’t try all 20 tonight. Here’s where to start.

21:16 When people reach out to me and ask, “How do I get started?” Uh I tell them to think of their most [music] routine work. Just open up Claude and and give it a shot. You really don’t know what it’s capable of doing until you give it a shot. >> Pick one boring job you do every week. Give it its own folder and run lessons four, six, and 12 on it. I put all 20 lessons, every command, and the seven mistakes on one free map. Comment 1,000 and I’ll send it to you. If you want the full playbooks, my paid
