Key Points Last 30 Days searches X, Reddit, and the web for content from the past month, creating highly optimized prompts for Claude Code. 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. Numbered Section Summaries 1. What Is "Last 30 Days"Matt explains the core problem: AI and online conversations move too fast to track manually. Last 30 Days solves this by aggregating real-time data from X, Reddit, and web searches into a single Claude Code skill, letting users become instant experts on any topic. 2. API Setup and How It WorksThe skill pulls together multiple API connections—OpenAI for Reddit access, XAI for X/Twitter search, plus standard web search. Matt notes he is exploring direct Reddit API integration to improve results further. 3. Cold Email Frameworks DemoMatt prompts the tool to research high-performing cold email techniques from the last 30 days, then uses that research to generate personalized outreach emails. The tool surfaces frameworks like AIDA, Three Ps (Praise-Picture-Push), and Intention Data Triggers—all without Matt reading the underlying research. 4. From Research to Product BuildThe episode moves into building a Moltbot competitor. Matt shows how he uses Last 30 Days to research Moltbot use cases, then feeds that intelligence into Compound Engineering to plan an enterprise-grade product from scratch. 5. Trending Web Design for Landing PagesMatt queries what website designs are getting the most love on X right now. Results include the Shopify "Winner Edition" page and a praised YC landing page. He then prompts Claude Code to generate a Figma-ready design spec for a SaaS productivity app. 6. Building Without Engineering SkillsMatt emphasizes he has not shipped production code since high school. His workflow involves running Claude Code in the terminal, taking screenshots of errors, pasting them into ChatGPT for debugging help, and iterating. The biggest unlock: learning to paste screenshots with Control+V instead of Command+V. 7. Getting Started RecommendationsMatt advises signing up for Claude Code's $20 plan, using ChatGPT as a troubleshooting copilot, and experimenting with skills like Last 30 Days and Compound Engineering. Trial and error, combined with lots of terminal windows, is the path forward.
