Community Skill Claude Code 2,000+ stars

/last30days

30 days of research. 30 seconds of work.

A Claude Code skill that researches any topic across Reddit, X (Twitter), and the web from the past 30 days, synthesizes what communities are actually discussing and upvoting, and delivers copy-paste-ready prompts tailored for any tool.

What It Does

AI guidance becomes outdated quickly. You get stale techniques when you need current best practices. /last30days bridges that gap by discovering what communities are actually discussing and upvoting right now, then synthesizing those findings into actionable prompts.

Reddit

Community discussions & upvotes

X / Twitter

Trending takes & viral threads

Web

Broader search & articles

How It Works

1

You ask a question

Type /last30days best prompting techniques for Midjourney

2

It researches across platforms

Searches Reddit, X, and the web for the last 30 days of real community discussions, weighted by engagement metrics (upvotes, likes, reposts)

3

Synthesizes findings

Extracts specific names, patterns, and insights - not generic advice. Grounds everything in actual research, not prior knowledge.

4

Delivers a copy-paste prompt

Asks what you want to create, then writes one perfect prompt in the format the research recommends (JSON, structured text, natural language, etc.)

Key Features

Prompt Research

Discover what prompting techniques actually work for any tool - ChatGPT, Midjourney, Claude, Cursor, Suno, and more.

Trend Discovery

Find viral trends you didn't know existed. Surfaces threads with 600-900+ upvotes that are shaping how people use AI tools.

Product Research

Get real-world use cases and community sentiment for any tool or product, complete with engagement metrics.

Developer Workflows

Find emerging patterns the community has developed, like the Claude Code + Codex review loop and other cutting-edge workflows.

Real-World Examples

The README includes 10 fully worked examples. Here are some highlights:

1

iOS App Mockup Generation

Researched prompt patterns for Nano Banana Pro, learned JSON-structured prompts work best, then generated a complete JSON prompt for a "SwimMom" app that produced a production-quality mockup.

2

Legal Prompting (Hallucination Prevention)

Discovered hallucination prevention patterns from legal communities, then generated a comprehensive legal research prompt with epistemic humility constraints.

3

Viral Trend Discovery

Found the viral "dog as human" ChatGPT image trend (600-900+ upvote threads), understood the exact prompting pattern, and generated a prompt that transformed a dog photo into a photorealistic human portrait.

4

Claude Code + Codex Workflow

Discovered the emerging "review loop" pattern for combining Claude Code and Codex via MCP integration - a workflow the community developed organically.
