Last30Days: A Claude Code Skill for Real‑Time Trending Prompt Research
Overview
Last30Days is a Claude Code skill that keeps you up‑to‑date by scanning Reddit and X for the latest discussions in the past 30 days. It then synthesizes the community’s favorite techniques, trending content, and real‑world results into a prompt you can copy‑paste straight into your target tool—ChatGPT, Midjourney, Claude, Figma AI, and more.
Why it matters
In the fast‑moving AI world, a prompt that worked last month may be obsolete today. Traditional research methods – reading blogs, watching videos, checking forums – are too slow. Last30Days automates that process, giving you the most current insights:
- Trend‑driven prompts – Find what the community is actually using.
- Tool‑specific best practices – Learn concrete, proven methods for ChatGPT, Remotion, Nano Banana Pro, etc.
- Product and marketplace research – Understand how new skills, plugins, and APIs are being adopted.
- Viral trend discovery – Spot emergent memes, music styles, and creative ideas before they saturate.
Key Features
| Feature | Benefit |
|---|---|
| Reddit + X search | 30‑day coverage across two major platforms |
| Synthesis engine | Identifies patterns, best‑practice clauses, and community opinions |
| Prompt generator | Produces copy‑paste‑ready prompts tailored to the requested tool |

Installation & Setup
Below is a quick start guide. You’ll need Git, Python 3, and at least one API key (OpenAI or xAI). If you want to contribute, fork the repo first.
# Clone the repository into your Claude skills folder
git clone https://github.com/mvanhorn/last30days-skill.git ~/.claude/skills/last30days

Using the Skill
After installing, launch Claude and type:
/last30days [topic] [for] [tool]
Examples:

The skill outputs either a ready‑to‑copy prompt or a concise, expert answer. The output includes:
- Community‑verified best practices (upvotes, likes, engagement scores)
- Concrete examples (code snippets, JSON prompts, video scripts)
- Contextual explanations (why the technique works, risks, limitations)
Real‑World Use Cases
1. Prompt Research for Legal Questions
The skill scans hundreds of legal‑discussion threads, identifies hallucination‑prevention strategies, and spits out a prompt that frames a legal research assistant role. This helps lawyers safely get structured summaries without risking misinformation.
2. Product Discovery for Developers
A dev team needing to evaluate whether a new CLIP‑based image generator is worth integrating can simply run:
/last30days best prompt for image generation with CLAIP
The response shows community‑popular prompts, usage guidelines, and engagement metrics.
3. Trend Tracking in Music
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.
4. Marketing & Social‑Media
Marketers track the dog‑as‑human meme trend, get example prompts, and instantly create their own content with minimal iteration.
