Last30Days — AI Trend Research Across 10 Platforms

What it is

Last30Days is a Claude Code skill that researches any topic across 10+ platforms from the last 30 days. It searches Reddit, X (Twitter), YouTube, Hacker News, Polymarket, Bluesky, TikTok, and other sources to synthesize grounded summaries with citations. The skill has 18,600+ GitHub stars and works with both Claude Code and Gemini CLI.

The skill targets developers, researchers, and product teams who need to quickly understand what the community is saying about a topic. Instead of manually checking each platform, the skill aggregates recent discussions and surfaces the most relevant insights.

How it saves time or tokens

Last30Days replaces the manual process of visiting 10 platforms, searching for a topic, reading through threads, and synthesizing findings. The skill handles multi-platform search, relevance filtering, and summary generation in a single command. Citations link back to original discussions so you can verify any claim. This reduces a multi-hour research task to a single agent invocation.

Common pitfalls

• Results depend on the search APIs available. Some platforms may rate-limit or require authentication for deeper access.
• The 30-day window means the skill misses longer-term trends. For historical analysis, combine with other research methods.
• Citation URLs may expire or be deleted. Save important references when you receive the research output.
• Always check the official documentation for the latest version-specific changes and migration guides before upgrading in production environments.
• For team deployments, establish clear guidelines on configuration and usage patterns to ensure consistency across developers.
