I fixed Claude Code for you in 30 seconds

I sit down with Matt Van Horn, creator of the "Last 30 Days" skill for Claude Code, as he demonstrates how this tool turns anyone into a real-time research expert. By pulling trending data from X, Reddit, and the web, Last 30 Days supercharges Claude Code prompts with current intelligence. Matt walks through live demos, from discovering popular rap songs to generating cold emails to building a Moltbot competitor, showing how non-engineers can ship products using AI tools with almost no coding background.

The tool requires Claude Code access, an OpenAI API key (for Reddit data), and an XAI key (for X/Twitter access). Matt demonstrates using minimal prompts to generate cold email frameworks, research trending topics, and kickstart new product builds. Compound Engineering serves as a planning tool to turn research into structured project roadmaps. Non-engineers can ship functional products by combining Claude Code with ChatGPT for troubleshooting errors via screenshots.

  There's a way to tune your Claude code so you get absolute superpowers. Some of my smartest friends are using this tool and it's called Last 30 Days. It just came out and I had the founder, Matt Van Horn, come on the podcast to show how to use it. What Last 30 Days does is it uses trending data on places like X and Reddit as the starting point for your prompts on Claude code. The cool part is you end up getting way more out of Claude code because the prompts are way more dialed and optimized. Enjoy the episode. Let me know if you think this is cool and I'll see you in there.

• 0:44Greg Isenberg?

  I feel like I'm in, I know I'm in for a treat. Matt Van Horn is on the podcast and he's gonna demo something very special. Matt, by the end of this episode, what are people gonna learn?

• 0:56Speaker 01

  They will have a new superpower in Claude code. It's called Slash Last 30 Days and it's gonna, for any topic you could possibly imagine, from best prompting techniques for a particular tool to how should I use Claude Bot? To what are the greatest rap songs right now? It's gonna search X, Twitter and the web for only things that have happened in the last 30 days and give you a great result and help you be expert.

• 1:22Greg Isenberg?

  My smartest friends are using this right now, so I had to ask Matt to come on and showcase how to use this. So thank you, Matt. I say we just get right into it.

• 1:32Speaker 01

  All right. Yolo. Let's, uh, let's go. I can just dive in. So we are in Claude code and so this is a skill for Claude code. And so, once you install it, you just type in Last 30 Days. So research any topic from the last 30 days. So.

• 1:53Speaker 01

  Can be anything. So let's say I want, let's kick one off right here.

• 2:01Speaker 01

  Most popular rap songs. So let's kick that one off. And so, and then I'll show someone some pre can ones I've done. So using the last 30 day school, it's research most popular rap songs. Let me research a popular rap songs in the last 30 days. And so right here, it's Reddit, reading what Redditors are saying, X, reading the timeline. And then it's also running a web search. So.

• 2:27Greg Isenberg?

  So is the, is the thinking like, is the reason why you created this is there's so much good data on the internet and you want to use that as like the jumping off point? Is that why?

• 2:36Speaker 01

  The, the reason that I built this tool is I feel like everything is moving so quickly in AI. And it's nearly impossible to keep up with the conversation on X, on Reddit, on GitHub. And I wanted a tool that gives you superpowers to be able to just become expert on any topic based on what's happening on Reddit, X and the web very, very quickly. Because the prompts are changing so quickly. What's happened? Like, look at, you know, malt bot. What's happened there? It's changing so quickly. And so being able to just become expert in something, it kind of reminds me in The Matrix when he gets plugged in and it's like, I know Kung Fu, right?

• 3:21Speaker 01

  So to be able to do that for any topic very, very quickly is, is why I built this. And honestly, so I could use it for myself. Looks like our, our rap research. So I found one Reddit thread, 19 expos and the most popular rap songs right now.

• 3:39Speaker 01

  So it kind of dug in and into hip hop heads, some expos, billboard data, some Spotify data, hip hop heads, hip hop all day, rap complex, and created this, this reply. So someone in the comment section is going to be like, well, I could have used perplexity or chat GPT to do that. Why should I use this? Yeah, so you absolutely could, but it's, and again, I'm not fully up to date on which, which tools have what access, but to set up last 30 days, so you need Claude code, right? So you're already paying for Claude code, right? So you need that account. You need a OpenAI key because OpenAI has a deal with Reddit that gives you that Reddit access.

• 4:25Speaker 01

  I'm actually looking into Reddit API keys, if that's an option, to make the product better. That's what I was, that's one of the things, my weekend projects. And then the, the third is you can't search X using your X account. You have to use an XAI key. And so Last30Days pulls in all these API keys and pulls it all together, if that makes sense. So this is one that I did right before we started. So I said, Last30Days: Highest Performing Cold Email Frameworks for ICP Output 3 Email Variants, Subject Line. So it went on X, went on Twitter, found Reddit threads, X posts, webpages. And what's

• 5:09Speaker 01

  interesting, how I use this tool, is I often don't even read what it says. Like, sure, it's interesting to see what it learned, but mostly I just wanted to write a good email. So I said, can you write me some cold emails for getting on Greg Isenberg's podcast? Sorry, I spelled your name wrong. Good target. Startup ideas later. It's all about unconventional startup ideas. Community building and founders' unique relevance. What's your angle? What's your credibility signal? Any connection points to Greg. Mutual follows. What timely? Talk about AI tools I'm working on. And I once made a smart oven. Smart oven details: Gold. Unexpected founders who shipped hardware and software. That's your hook. Here are three email variants. Subject: Smart oven AI tools, not the path of Greg. I went from building smart oven to building AI tools. That might sound weird until you hear it.

• 5:54Speaker 01

  Turns out the hardest part of hardware taught me exactly what's broken and how people interact with AI and I'm building the fix. Katrina, what a smart oven taught me about AI. So anyway, I literally did nothing here. I barely gave it any context and it had become expert in different cold emailing concepts. The three Ps framework, praise, picture push, Ada, attention. I've never written any of these in my life. Intention based data trigger framework. And then it just did it for me, if that makes sense, without even me having to read the research.

• 6:25Greg Isenberg?

  Yeah, I think what's really cool about this is these frameworks. I mean, Ada has been around forever, like, you know, OG David Ogilvy days. But other than, you know, the other ones, like, it feels like those are timely frameworks. Like, these emails, like, I'm reading these emails and they're, I get a lot of cold email and these are actually ones that would break through the noise. So that's what's really cool about this.

• 6:51Speaker 01

  And I didn't even give it much effort. I literally said, I'm a former smart oven entrepreneur.

• 6:58Greg Isenberg?

  You couldn't have given it, like, less context.

• 7:01Speaker 01

  And it did okay. And then another one, I just tried, last 30 days, how to get X followers. Our research people are actually saying. And what I learned, replies the number one growth strategy. Multiple X power users, all credit, becoming a reply guy as the fastest path to growth. Shows 30, 80 thoughtful replies, daily engagement, 40 minutes before posting. Find larger accounts, reply first consistently. Post at least one X a day, five days a week. Reddit threads, X threads, Instagram marketing, Facebook ads. And share your vision, what's your account and what's the followers? I'm Van Horn and I made an AI tool for Claude code.

• 7:44Speaker 01

  I don't know what it's gonna do now.

• 7:48Greg Isenberg?

  That's the exciting part.

• 7:49Speaker 01

  One, one other, let's spin off another last 30 days window. Sorry for all the, all the windows. So, all right, so last 30 days of research.

• 8:05Speaker 01

  Claude, Claude Bot, so I can build an enterprise competitor to make money and not give it away for free. Maybe I'm giving too much context, but I should have just said research Claude Bot. Actually, I'm going to do that.

• 8:26Greg Isenberg?

  I mean, what do you recommend when you're, you know, is it shorter prompts, medium prompts, long prompts, like getting the most out of?

• 8:34Speaker 01

  I think it's, it's kind of, you prime the engine by first doing just research Claude Bot, top use cases. So what my, my vision for this thread of what we're going to do is it's going to learn about Claude Bot, right? Check X, check Reddit. And then what I'm going to do is actually load one of my favorite tools, Compound Engineering. Shout out to Kevin Rose for introducing me to it. And Compound Engineering is when I'm starting a new project is where I do my planning. And so what I want to do here is take this research on from last 30 days from Claude Bot and use that as the starting point to

• 9:16Speaker 01

  kick off a enterprise version of Claude Bot and to build it. So let's, let's let this run and see how our other stuff is going. All right. I remember I'm in AI tools for Claude code. AI tools are hot right now. Here's a growth playbook for you. Morning, 40 minutes for your first post. Reply to TED from Anthropic, Alex Alber, Birch Labs, Claude Power users at genuine value. Share a tip, ask a smart question, content type, tool demo, build X today, what it does, Claude code tip, five things I learned X, build in public, shit. By the way, I'm not going to do this. I think this was just, I actually asked chat GPT for suggestions of what I should demo on your show and it gave me this one. But quickest wins, pin your best demo tweet, show the tool in action, bio formula,

• 9:59Speaker 01

  I build tool, one line of shipping AI tools for Claude code.

• 10:03Greg Isenberg?

  That's not bad.

• 10:04Speaker 01

  No, it's, it's not bad. So all right, let's close this one out. All right, we got Claude code, best use overnight coding agent manager, daily briefing some morning. Do you want to dive deeper? Okay, so now I'm going to call in another tool. Let's plan, throw in workflows plan. Take the context above about Claude Bot and

• 10:28Speaker 01

  Propose an enterprise version that could make a lot of money. Just do that. Keep it simple.

• 10:39Greg Isenberg?

  Yeah, I mean, this is, this is interesting, right? Like, you know, you're taking a trend, open source trend, and you're like, okay, how can I build a product that, you know, gets me paid? And it's interesting because there's so many trends that are happening right now on X as like a data source and Reddit as a data source that, you know, if this, if this is actually good, is going to help give you ideas and sort of eventually a PRD, right?

• 11:07Speaker 01

  Yep. Anyway, so it's still making our plan. It's researching still, doing an analysis. So we'll, we'll see where that adds up. But anyway, do you want to try a last 30 day prompt?

• 11:19Greg Isenberg?

  Yeah, I mean, I'm curious, like, I mean, you're seeing all the, all these prompts. So like the people that listen to this show, these are people, these are founders, entrepreneurs, people building businesses. They're always looking for unfair advantages. Like what sort of, what sort of prompt do you, would you suggest that type of person? Someone who wants to build a business? You know, is it competitive research? Is it, you know, what are some ideas you have?

• 11:52Speaker 01

  Ooh, good, good question. I mean, I think it's, it's very good for competitive research. I think it's very good for looking at, at hot topics. I think it's, you know, we could probably do something like, you know, let's try it for your, your web design idea, right? You kind of described poke.com, which I missed, right? So what webpage designs are getting the most love right now?

• 12:23Greg Isenberg?

  Yeah, because that's interesting because if we, you know, knowing the trend is just so important. And

• 12:32Greg Isenberg?

  It also helps like give, you know, when I'm, when I'm designing something, it helps give me ideas. It gives, it's so overwhelming sometimes when you have like a blank page and you don't know where to start.

• 12:43Speaker 01

  Yep.

• 12:44Greg Isenberg?

  We've all been there.

• 12:46Speaker 01

  And I kind of my, kind of the, the, the thing that inspired this tool was I used to before I would jump into any type of vibe coding session, I would go on chat GPT 5.2 and I would just say in thinking mode and be like, go, uh, this was for design. I would say, go on Reddit and research Nano Banana Pro best, best prompting techniques. And I would do that at the beginning and then I wouldn't even read what it would say. And then I would just be like, okay, give me a prompt. And so it's, it's kind of this like hack of, you know, learning Kung Fu, learning the prompts that everyone's using without actually needing to

• 13:31Speaker 01

  read about it, if that makes sense. You could kind of just like, okay, let's just trust the, the, the mind crowd, the, the world that's out there and, and use those best practices. All right. We've got a plan. Let's, uh, I guess let's open the plan in BB edit. All right.

• 13:53Greg Isenberg?

  So this is the plan for, for the audio listeners. So this is the plan for the, the

• 13:58Speaker 01

  Moltbot enterprise commercial SaaS platform. So again, this is not a business plan. This is actually a plan to how to build the software architecture. And I could just then tell compound engineering to just go build it. So transform Moltbot, formerly called into an open source AI person, into a multi-tenant enterprise SaaS platform called Moltbot Enterprise or Claude Cloud. This capitalizes on the viral growth, GitHub stars, B2B adoption, enterprise AI assistance, R30, blah, blah, blah. Why enterprise can't use Moltbot today, no multitasking, no R, eh, security vulnerabilities, no audit logging, like, uh, the move vice required by service now for market validation, proposed solution of fully managed enterprise grade Moltbot

• 14:43Speaker 01

  commercial. I really don't like the name Claude Cloud. Come on. Come on, LLM, Cloud Architecture, Slack Webbook, Discord Gateway, Teambooks, Message Reader, Core Technical Components. And so it used last 30 days as the basis for its expertise to learn about Moltbot, and then it did the rest. And now I could just say, "Okay, build it."

• 15:10Greg Isenberg?

  Dude, that's crazy. And also, that was a pretty, that was pretty dialed. Like, that was pretty dialed.

• 15:17Speaker 01

  And again, like, I'm impressed. And LLMs knew nothing about Claudebot, because it didn't exist before. It didn't exist till very, very recently. All right. Phase one only, build a multi-tenant foundation, postgressql, full MVP. I guess let's build the proof of concept.

• 15:43Greg Isenberg?

  So, so basically, you know, it asked if you wanted to do an MVP. It asked if you wanted to do a bigger build. Is that, is that what I saw?

• 15:50Speaker 01

  Yeah, exactly. And so I just said, "Okay, let's just do the demo."

• 15:55Greg Isenberg?

  Yeah.

• 15:56Speaker 01

  "Type something else. New repo. Also, can you please give it a better name?" Greg, you're, you're, you live in this world. What should we call this thing?

• 16:05Greg Isenberg?

  I mean, why not? I actually don't hate Claude Cloud. It just,

• 16:12Speaker 01

  Well, they got in trouble for using Claude.

• 16:15Greg Isenberg?

  Exactly. So why not just call it Molt Cloud?

• 16:18Speaker 01

  But then we're getting in trouble with Molt.

• 16:21Greg Isenberg?

  Molt? Okay, so why don't we call it?

• 16:24Speaker 01

  Should we go Lobster?

• 16:29Greg Isenberg?

  I was gonna say, why don't we call it Red Lobster?

• 16:32Speaker 01

  But I think that name is already pretty good. All right, let's go, let's go with lead speak.

• 16:38Speaker 01

  Let's go with Red Lobster.

• 16:40Greg Isenberg?

  That's cool.

• 16:41Speaker 01

  This describes a 40-week product survey. What scope do you want to do? I don't know. Just do it.

• 16:47Greg Isenberg?

  Just do it. Why are you asking me so many questions?

• 16:51Speaker 01

  All right. All right. What do we ask here? What web designs are getting the most love right now? The most loved Shopify winner edition. Yes, I remember. I saw that one. That was really nice.

• 17:01Greg Isenberg?

  That was really awesome. That was beautiful.

• 17:04Speaker 01

  Look, 3,000 likes, 320 retweets, the YC landing page. So what's funny is I saw this. I didn't actually look at it yet, but I saw that it was getting love and hype. Praise for scrappy home of beginnings, shop, web landing, all were like jewelry, craft works, design. All ages reported back. Reddit didn't find anything. Topic too visual for text discussions, but found, what tool do you want to use to create design? So it's like, okay, now that I've researched these things, what do you want to design in? Right?

• 17:36Speaker 01

  So it's kind of, it's kind of pushing you to be like, okay, I've now learned this expertise. Now let's do something with it.

• 17:44Greg Isenberg?

  So this could literally pump out a Figma design? Is that possible?

• 17:49Speaker 01

  I haven't spent enough time in Figma in the AI era. All my Figma time was pre-AI. So I don't know what like prompting Figma even means in 2026. But I don't know. I could just say one and see what happens.

• 18:04Speaker 01

  Now what are you designing? All right, now it's diving in.

• 18:09Speaker 01

  A portfolio of landing page for productivity app is fine. One of the suggestions.

• 18:20Greg Isenberg?

  This is what are you designing? A SaaS landing page, a portfolio site, an e-commerce homepage for skincare brand, agency website hero.

• 18:28Greg Isenberg?

  And so I keep coming back to this, but it's, it is impressive how little you're giving, like how short your prompts are.

• 18:38Speaker 01

  Here we go. Here's a prompt for Figma. Apparently, that's the thing. 2026 Forward Trend. Design a language that feels warm and human, not cold, sassafer. Layout anti-grid composition. Hero section uses asymmetrical balance. Headline left, product screenshots floating right at angle. Section will flow organic with varied spacing, not rigid, 12-column uniformity. Typography: One oversized display headline paired with small-body text. Add a single hand-drawn underline or circle accent on the keyword. Consider variable font like Satoshi or General Sans. Nature-distilled, warm-cream background, charcoal text, one muted accent. Avoid harsh, pure white or saturated blues. Glass morphism element, feature card.

• 19:18Speaker 01

  I want to see this. It's too bad I don't have Figma AI setup. But that was pretty cool.

• 19:27Greg Isenberg?

  Let's see if it can do this for like a nano banana prompt. Like, hey, I wonder if it can do that. Can you make this a nano banana pro prompt?

• 19:39Speaker 01

  Yep, but I didn't ask it to become expert in it.

• 19:43Greg Isenberg?

  A nano banana.

• 19:45Speaker 01

  I didn't ask it to become a nano banana prompt expert, so who knows what's gonna happen?

• 19:49Greg Isenberg?

  Yeah. Back to Telegram, and let's see what happens. We should get three images. Your malt bot is typing. That's a cool feeling, like watching your malt bot type.

• 20:07Speaker 01

  Someone needs to visualize that with like a lobster on a keyboard.

• 20:16Greg Isenberg?

  Why did you choose Telegram over iMessage or Discord or something else?

• 20:23Speaker 01

  Because my LM told me to. Because I'm on a $4 a month Shell account for my... I don't have the Mac Mini setup, and so the... You can't use iMessage or WhatsApp, I believe, when you're just on a Shell. I think you need to run some sort of Mac software. And so Telegram seems to be the default when you don't have that.

• 20:50Greg Isenberg?

  And for people who don't know what a Shell account is, can you just expand on that?

• 20:54Speaker 01

  Yeah, sorry. By the way, this is our Claude bot competitor that it's building. I don't know what is going on or what it's building. It's adding a demo script showing tenant isolation, then oh, it already set up TypeScript and Node.js. That's nice.

• 21:11Greg Isenberg?

  Wow, that's cool.

• 21:14Speaker 01

  Here we go.

• 21:16Greg Isenberg?

  Oh, yeah.

• 21:18Speaker 01

  Not bad. It better be nicer in Figma. Yeah, that was pretty solid. And again, that was by using slash last 30 days. What are the hottest webpage designs that the world is excited about right now? Like, what's trendy? And then, okay, now use that to for my SaaS productivity app. I like how it like circled random words, flow effortlessly, more.

• 21:39Greg Isenberg?

  That's awesome. Yeah, like it feels like hand drawn.

• 21:42Speaker 01

  It's a, it's pretty wild. It's, it's wild times. It's the rate at what we're, we're able to build things and how fast things change is absolutely wild.

• 21:54Greg Isenberg?

  So Matt, this has been fun. You know, if people want to get started, they want to, like, what advice do you have? You know, in terms of getting the most out of this product?

• 22:09Speaker 01

  Yeah. So one of the things I'll say is I, I am not a software engineer. I have not shipped anything of value since high school and could argue the webpages I was shipping in high school were not of value either, but at least I could write some, some basic HTML or some basic scripts. And so what's,

• 22:29Speaker 01

  what's amazing is being not a software engineer and being able to go into Claude code. Like, it seems intimidating. You're in the terminal, setting up a Claude bot seems intimidating. And my recommendation for starting out is set up, set up Claude code. It's magical. Sign up for the $20 account. If you'll be on the $100 and the $200 account probably real soon if you're, if you're successful. And, and what I, what I do is I.

• 23:05Speaker 01

  Have keep a chat GPT window open to ask questions to. And so I'm kind of moving back and forth and posting lots of screenshots be like, there's some error. I don't know what's going on. Help me. And so chat GPT five two thinking will be like, okay, great. In your in your shell, in your terminal, this is what's going on. This is why it broke. And I'm like, okay, great. What do I do? Help. And then it's just like, copy this into the terminal. I'm like, okay, and I again, don't even have to read it. Don't have to overthink it. And so kind of just like screenshot trial and error back and forth between chat GPT and my terminal. And like, I couldn't figure out actually how to post screenshots into my terminal. So I asked chat GPT. And it's like, oh, you have to use Ctrl V instead of Command V. And the ones that that was the biggest unlock for me in the terminal.

• 23:49Speaker 01

  Figure out that I could post screenshots with Ctrl V. And anyway, so I recommend getting into Claude code and and try last 30 days, obviously, because it gives you superpowers. But use tools like compound engineering, use skills like there's another one called superpowers, which is getting a lot of love right now. And you just kind of enter these plan modes and you try and you build things. And I had this idea for last 30 days. And I've never looked at the code for the skill that I wrote, quote unquote. And it was just a lot of trial and error and running more and more terminal windows and testing it and testing it and being like, hey, figure out how to get access to this API. Hey, figure out how I could do this.

• 24:34Speaker 01

  Hey, how can my users do this? And going from there.

• 24:38Greg Isenberg?

  I love that, man. Well, I'll include a link to last 30 days in the show notes in the description. Link where where you can follow Matt Van Horn on X. And dude, this is this is really cool. And it's crazy that this is just sort of like a project that you started. And it's gaining so much traction. And I think people are just, you know, obsessed with Claude code for, you know, for good reason. But I think people are just trying to get the most out of it. So this this came at a very perfect time and and I can't wait to see how it evolves. And thanks for doing a little show and tell for us.

• 25:16Speaker 01

  Of course, it was fun being here. Thank you so much, Craig.

• 25:18Greg Isenberg?

  I appreciate it, Matt. Until next time.
