How to supercharge Claude Code with the Last 30 Days skill

The smartest developers aren't just using Claude Code - they're using it with a secret weapon called Last 30 Days. This simple skill transforms Claude from a helpful coding assistant into something much more powerful: a research supercomputer that knows exactly what's trending right now.

While most people struggle to keep up with the lightning-fast pace of AI development, Last 30 Days gives you an unfair advantage. It scans Reddit, X, and the web for the latest discussions from the past 30 days, then injects that trend-aware context directly into your Claude prompts.

What makes Last 30 Days different from regular research?

Traditional research is broken in the AI world. By the time someone writes a blog post about a new technique, shares it on social media, and you finally read it - the landscape has already shifted. AI tooling moves faster than documentation. Faster than blog posts. Faster than most humans can keep up with. Prompting advice from six months ago is already stale.

Last 30 Days does exactly one thing, and does it aggressively well. It searches X, Reddit, and the web for only content from the last 30 days, then uses that data as the starting context for your Claude prompts. Actual, opinionated, trend-aware context injected directly into your prompt. The result: Claude stops sounding like a textbook and starts sounding like someone who has been online recently.

You're not getting summaries to read or links to click through. The skill delivers copy-paste-ready prompts that work today, not six months ago.

How does Last 30 Days actually work?

The magic happens in three steps: search, synthesize, and inject. Last 30 Days researches your topic across Reddit, X, and the web from the last 30 days, finds what the community is actually upvoting and sharing, and writes you a prompt that works today, not six months ago.

To get started, you need Claude Code, plus API keys for OpenAI (Reddit access) and XAI (X/Twitter access). To set up 'Last 30 Days', you need a Claude Code account, an OpenAI API key (for Reddit access), and an XAI key (for searching X). The skill integrates these API keys to pull data from various sources.

Installation is straightforward:

1. Clone the Last 30 Days repository
2. Set up your API keys in the configuration
3. Type /last30days followed by your research topic

The skill automatically searches across platforms and returns actionable insights with engagement metrics that tell you what people actually care about.

What kinds of problems does this solve?

The use cases are surprisingly broad. Best for prompt research: discover what prompting techniques actually work for any tool (ChatGPT, Midjourney, Claude, Figma AI, etc.) by learning from real community discussions and best practices. But also great for anything trending: music, culture, news, product recommendations, viral trends, or any question where "what are people saying right now?" matters.

For developers: Research emerging frameworks, discover community-developed workflows for combining AI tools, and find real patterns that aren't in official documentation yet. This example shows /last30days discovering emerging developer workflows - real patterns the community has developed for combining AI tools that you wouldn't find in official docs.

For marketers: Track viral trends, get example prompts for current memes, and create timely content with minimal iteration. Marketers track the dog-as-human meme trend, get example prompts, and instantly create their own content with minimal iteration.

For content creators: Find what music tracks are hot, learn the structure of viral songs, or discover the latest techniques for image generation tools. Music producers discover what rap tracks are hot this week, learn the structure of viral songs, and even generate their own song prompts using the skill's Suno-specific suggestions.

What's the secret to getting better results?

Smart users follow a two-step approach: prime first, then execute. Before diving into specific tasks, use Last 30 Days to research general topics related to your goal. This helps the tool learn and provide better, more informed outputs.

Start with shorter prompts to get initial research, then build on those results with more detailed requests. Start with shorter, simpler prompts to get initial research and then iterate with more detailed prompts based on the results.

The most effective approach combines Last 30 Days with other Claude Code skills to create comprehensive workflows based on trending insights.

Why aren't more people using this approach?

The skill has already gained significant traction - Last30Days has already amassed 1.5k stars on GitHub, showing strong community interest. But many developers still don't realize how much the landscape has changed.

Most people use Claude Code like autocomplete. Some use it like a junior developer. But the power users understand something different: the real competitive advantage isn't in the AI itself, but in feeding it the right context at the right time.

In a recent podcast episode, founder Matt Van Horn demoed how this simple Claude Code skill changes prompting from guesswork into something closer to cheating — in a socially acceptable way.

What does this mean for non-technical users?

You don't need to be a software engineer to benefit from this approach. The creator, Matt, emphasizes that he is not a software engineer and has been able to use Claude Code and 'Last 30 Days' effectively. He recommends using ChatGPT alongside Claude Code for troubleshooting and guidance, making it accessible for non-engineers to build and experiment with AI tools.

The setup requires some technical configuration, but once installed, using the skill is as simple as typing a command and describing what you want to research.

The bigger shift is conceptual: instead of asking AI tools generic questions, you're asking them to build on real, current conversations happening in your field. This turns every prompt into a conversation with the collective intelligence of your industry's most active communities.

The AI world moves so fast that yesterday's techniques are already outdated. Last 30 Days gives you a way to stay current without spending hours scrolling through forums and social media. It's not just about better prompts - it's about having access to the collective knowledge of communities that are solving problems right now, today, in real time.
