Public repository for Agent Skills

View on GitHub

What it does

This is Anthropic's official library of 'skills' — pre-built capabilities that can be plugged into Claude AI agents, allowing them to perform specific tasks like browsing the web, writing code, or managing files. Think of it as an app store of abilities for AI assistants, where each skill is a ready-made module that gives an AI agent a new power without having to build it from scratch.

Why it matters

With over 122,000 stars, this is one of the most-watched repositories on GitHub, signaling that AI agents with modular, composable capabilities are becoming a serious building block for products — not just a research concept. Builders and investors should pay attention because whoever controls the standard for how AI agents acquire and share skills could have significant influence over how the next generation of AI-powered software is architected.

Why it's trending

Anthropic just made it significantly easier to build AI agents that actually do things, and the developer community noticed fast — this repository pulled in nearly 5,000 stars this week alone and is generating serious conversation on Hacker News, with 20 mentions this week as part of a broader 79-mention month. The appeal is straightforward: instead of every team building their own file-writing, web-browsing, or search logic from scratch, Claude can now pull from a shared, officially maintained library of pre-built actions. Worth noting that star growth actually slowed 38% from last week's peak of nearly 8,000, so the initial viral spike may be cooling — but with only 6 commits in the last 30 days and 11 contributors managing a 120,000+ star project, builders watching this space should track whether Anthropic ramps up development velocity to match the clear market demand.

This is Google's official collection of tutorials, code examples, and ready-to-run notebooks showing builders how to create AI-powered applications using Google's Gemini models on its cloud platform. It covers everything from basic AI conversations to complex multi-step AI agents that can reason and take actions autonomously.

// why it matters With over 15,000 stars and nearly 300 contributors, this repository signals where serious enterprise AI development is heading — Google's cloud ecosystem is positioning itself as a primary destination for teams building production AI products. For founders and PMs evaluating AI infrastructure, this gives a clear picture of Google's capabilities and provides a fast track to building on the same models powering consumer Google products.

Hermes Agent is an AI assistant that gets smarter the more you use it — it remembers past conversations, learns new skills from experience, and builds a profile of who you are over time, all without being tied to any single AI provider or device. It runs in the cloud and connects to messaging apps like Telegram, Slack, and WhatsApp, so you can interact with it anywhere while it handles complex tasks in the background.

// why it matters As AI assistants become a core part of how teams and products operate, the ability to avoid vendor lock-in while building a continuously improving, memory-rich agent is a significant competitive advantage — this is the kind of infrastructure layer that could sit underneath entire products or workflows. With nearly 9,000 stars and over 100 contributors, it signals strong developer demand for agents that persist, learn, and work autonomously rather than resetting with every session.

AITER is AMD's open-source library of high-performance building blocks that make AI models run faster on AMD hardware, supporting everything from basic AI operations to complex training and multi-GPU coordination. Think of it as a toolbox that lets AI software teams tap into AMD's chip capabilities without having to write low-level hardware code themselves.

// why it matters As AI infrastructure costs soar, builders are actively exploring alternatives to Nvidia's dominant GPU ecosystem, and AMD is positioning AITER as the key compatibility layer that makes switching or diversifying hardware more practical. For founders and PMs building AI products, this means AMD GPUs become a more credible option for cost reduction or supply chain diversification — especially relevant as demand for AI compute continues to outpace supply.

Last30Days is a plug-in skill for the Claude AI coding assistant that automatically researches any topic across Reddit, X, YouTube, Hacker News, Polymarket, and Bluesky, then produces a cited summary of what people are actually talking about right now. Think of it as a one-command briefing tool that scans the social web for the past 30 days and distills the signal into a readable report, saved automatically to your computer.

// why it matters As AI tools and markets shift weekly, founders and product teams who can quickly validate what's gaining traction — before it becomes mainstream knowledge — have a real edge in prioritization and positioning. The 15,000+ stars suggest strong demand for ambient, automated trend intelligence baked directly into developer workflows rather than requiring separate research tools.
