awesome-agent-skills is a curated collection of over 1,100 agent skills contributed by official engineering teams — Anthropic, Google, Vercel, Stripe, Cloudflare, Netlify, HashiCorp, Trail of Bits, Sentry, Hugging Face, Figma, Expo, and others. Each skill is vetted and works across Claude Code, OpenAI Codex CLI, Gemini CLI, and Cursor. VoltAgent is explicit that this is "hand-picked, not AI-slop generated." The project fills a gap that's emerged as agentic coding platforms have proliferated: each platform has its own skill/command format, and developers end up rebuilding the same auth flows, API integrations, and test harnesses for each one. awesome-agent-skills provides a universal, cross-platform skill layer maintained by the companies that built the APIs being automated. As of this week, the repo is trending on GitHub with 139 new stars today, bringing the total to 16.9k with 1.8k forks. VoltAgent also maintains companion repos: awesome-openclaw-skills (5,400+ skills for Claude Code specifically) and awesome-ai-agent-papers. For developers building on any agentic coding platform, this is quickly becoming the first stop before writing a custom integration from scratch.

Libretto is an open-source TypeScript toolkit for building and maintaining browser automations that are actually reliable. Unlike most AI-driven browser tools that use probabilistic reasoning to select elements at runtime, Libretto works by having the AI generate deterministic selectors and action sequences upfront — then executing them with zero LLM involvement at runtime. The AI is your authoring tool, not your runtime dependency. The core insight: most AI browser automations fail in production because they call an LLM on every page interaction. Libretto flips this by using AI to write and update the automation scripts, but running them as ordinary code. When a site changes and your automation breaks, Libretto detects the failure and prompts you to let AI update the selector — then it's deterministic again. Built by the team at Saffron Health, the library hit HN's front page today and is generating discussion as a more pragmatic alternative to fully autonomous browser agents. For anyone who's tried Playwright with AI wrappers and found them unreliable in CI/CD, this is the architecture that's been missing.
Reviewer scorecard
“Official skills from the companies that built the APIs are a different category from community-written scripts. When Stripe's own team ships a payments agent skill, I trust it handles edge cases my homegrown version would miss. This is the npm registry for agentic coding.”
“This is the right mental model for production browser automation. Using AI for authoring but not runtime means you get consistency in CI without random failures at 2am. I've been waiting for someone to build this properly.”
“1,100+ skills sounds impressive until you realize most of them are thin wrappers that call the same APIs you'd call directly. 'Official' doesn't mean secure or well-maintained — a star count and corporate logos are not a substitute for auditing skills you're giving your AI agent.”
“The 'AI updates your selectors' workflow sounds great until you're reviewing 50 AI-generated selector changes after a site redesign. You've just moved the flakiness from runtime to the maintenance loop. Also, 37 stars is very early — I'd wait for production case studies.”
“The emergence of a skills marketplace with official vendor buy-in is a structural shift: the agentic coding ecosystem is maturing from 'DIY everything' to 'pull from a curated catalog.' This is the infrastructure layer that makes agentic development teams viable at scale.”
“The deterministic-at-runtime pattern will become the standard architecture for AI-assisted automation. Libretto is arriving exactly as enterprises start demanding reliability SLAs from their AI tooling. Early movers will have a significant advantage.”
“Figma's presence in the contributor list is what gets my attention. Cross-platform creative workflow automation via official agent skills — rather than fragile screen-scraping hacks — is a meaningful step toward AI-assisted design pipelines that actually hold up.”
“As someone who automates repetitive web tasks constantly, this solves my biggest frustration — AI-written automations that fall apart the moment a site updates their CSS. The auto-repair loop is exactly what I need for long-running workflows.”
