AI Skill Tracks 30-Day Trends Across Social and Tech Platforms 🔗
Comprehensive research agent delivers grounded insights from recent online conversations to keep builders informed and competitive
The mvanhorn/last30days-skill is an AI agent skill that researches any topic across Reddit, X, YouTube, Hacker News, Polymarket, Bluesky and the wider web from the last 30 days, then synthesizes a grounded summary complete with real citations. In an industry where new frameworks, techniques and paradigms emerge constantly, the skill solves a fundamental developer problem: how to stay current without spending hours manually trawling disparate platforms.
Rather than relying on static training data or generic web searches that mix old and new information, last30days deliberately limits its scope to the most recent month of activity.

Rather than relying on static training data or generic web searches that mix old and new information, last30days deliberately limits its scope to the most recent month of activity. It identifies what the community is actually upvoting, discussing in comments, betting on through prediction markets, and demonstrating on camera. The result is a narrative that reflects real sentiment instead of recycled hype.
Recent releases have significantly expanded its power. Version 2.9.5 adds full Bluesky support through the AT Protocol, requiring only a handle and app password. The new comparative mode lets users query topics such as "cursor vs windsurf" and receive three parallel research passes that produce a side-by-side analysis, strengths and weaknesses breakdown, head-to-head table, and data-driven verdict. Configuration improvements include per-project .claude/last30days.env files and automatic validation when Claude Code sessions begin.
The technical implementation reveals careful attention to data quality. Reddit now defaults to the ScrapeCreators API, which also covers TikTok and Instagram under a single key, eliminating the need for separate OpenAI credentials. Smart subreddit discovery replaces simple frequency counts with a weighted score of frequency × recency × topic match, while a UTILITY_SUBS blocklist filters out irrelevant communities. Top comments receive explicit 10% weight in engagement scoring and appear prominently with upvote counts and 💬 indicators, acknowledging that Reddit's real value often lives in the discussion threads.
Every run automatically saves the complete briefing as a topic-named Markdown file in ~/Documents/Last30Days/, creating a personal research library without extra effort. The project ships with more than 455 tests covering all modules, demonstrating a commitment to reliability that matches its ambition.
For developers working at the cutting edge of AI, this skill functions as an intelligence amplifier. It captures signals across different mediums — the rapid chatter of X, the visual demonstrations on YouTube and TikTok, the market wisdom of Polymarket, and the thoughtful discourse on Hacker News — then distills them into coherent insight. The temporal focus ensures summaries reflect the current moment rather than last year's consensus.
The skill's approach highlights a maturing category of AI tooling: specialized agents that excel at information synthesis rather than general code generation. By grounding outputs in verifiable recent community activity, it helps builders make better decisions about which technologies deserve attention and which are merely noise.
As the pace of AI innovation continues to accelerate, tools that efficiently surface what engaged practitioners already know become essential infrastructure. The last30days-skill achieves this by combining broad platform coverage, intelligent filtering, comparative analysis, and seamless integration into existing developer workflows. Its automatic archiving feature further turns one-off questions into a cumulative knowledge asset that grows more valuable over time.
Key technical capabilities:
- Multi-source engagement scoring with temporal filtering
- Smart community discovery and noise reduction
- Comparative analysis with structured tables and verdicts
- Automatic local Markdown archiving for personal knowledge bases
In essence, this project changes how developers maintain awareness in a chaotic information ecosystem, replacing manual effort with reliable, citation-backed intelligence that keeps them plugged into the living conversation of their field.
- Developers synthesizing latest AI trends from multiple platforms
- Engineers comparing competing tools through community data analysis
- Builders creating automatic personal research libraries over time
- Perplexity - provides general AI search but lacks this skill's strict 30-day community focus and multi-platform synthesis
- CrewAI - offers frameworks for building custom agents whereas this delivers a ready-to-use, opinionated research pipeline for Claude Code
- AutoGen - enables multi-agent collaboration while this specializes in timely social listening and grounded narrative generation
