Awesome Agent Skills is a curated repository of over 1,100 agent skills from official development teams and the open-source community, organized for use with Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot, Windsurf, OpenCode, and more. Maintained by VoltAgent, the collection explicitly rejects AI-generated filler — everything is hand-picked. The library spans every corner of the modern developer stack: frontend frameworks (React, Next.js, Angular, React Native), cloud platforms (Cloudflare Workers, Netlify, Vercel, Google Cloud), databases (PostgreSQL, ClickHouse, MongoDB, Firebase), infrastructure (Terraform, HashiCorp), CMS (Sanity, WordPress), APIs (Stripe, Composio, Firecrawl), AI/ML (Replicate, Gemini, OpenAI), and design (Figma, Remotion). Skills from Stitch, Remotion, and dozens of official vendor teams are included. As agent-native development becomes the default workflow, having the right skills loaded into your agent is as important as having the right VS Code extensions was in 2020. This is becoming the npm registry of agent capabilities — 18k+ stars and still climbing.

Libretto
Deterministic browser automations for AI agents — 95% success rate

Libretto is an open-source browser automation toolkit built by Saffron Health to solve a critical problem with AI-driven web agents: non-determinism. Standard agent-controlled browsers using Playwright or Puppeteer routinely fail 20-30% of the time on production workflows because they rely on LLM judgment for timing and element selection. Libretto replaces that with a record-replay system that captures precise interaction timing and DOM fingerprints, achieving a reported 95% success rate on identical workflows. The library works by recording a "golden path" of a browser session — capturing not just actions but the exact CSS selectors, visual context, and timing windows during which those actions are valid. On replay, it verifies each step against expected page state before proceeding, and falls back to an LLM-assisted recovery mode when pages drift (e.g., after a UI update). Saffron Health built it to maintain integrations with EHR portals that change frequently and where failure has compliance consequences. Saffron open-sourced Libretto after using it internally for 18 months across 40+ healthcare software integrations. The HN thread highlighted the appeal for fintech, legal, and healthcare automation where reliability, not just capability, is the product. The toolkit targets TypeScript/Node.js environments and integrates cleanly with existing Playwright infrastructure.
Reviewer scorecard
“This is the package registry equivalent for agent skills. Instead of hunting across 30 different repos, everything is here and organized. The fact that official vendor teams like Stripe and Cloudflare are contributing their own skills means quality stays high.”
“Record-replay with LLM fallback is the right architecture for production browser automation. The 95% vs 70% success rate gap is enormous when you're running 1000+ workflows. The Playwright integration means zero migration cost for existing projects — just wrap your sessions.”
“1,100 skills sounds impressive but quantity isn't quality. Keeping skills current as APIs evolve is a massive maintenance burden — today's Stripe skill becomes tomorrow's broken context blob. Absent a strong contributor community, this risks becoming stale fast.”
“The 95% figure is from Saffron's own healthcare-specific workflows — your mileage may vary significantly on SPAs, infinite scroll, or JS-heavy sites. Recording golden paths also means maintenance overhead whenever target sites update their UI, which can be frequent.”
“The aggregation layer for agent tooling will be enormously valuable. Whoever owns the canonical skills registry wins developer distribution the way npm and pip did before — Awesome Agent Skills has first-mover positioning in a winner-take-most market.”
“The AI agent reliability problem is underrated. Most agent failures aren't reasoning failures — they're execution failures in the browser layer. Libretto's approach of constraining the non-determinism surface is exactly the right abstraction for enterprise adoption of browser agents.”
“Having Figma and Remotion skills officially in here means designers can plug into agentic workflows without translating their tools into developer language. Exactly the kind of cross-discipline thinking that makes agent tooling accessible beyond pure coders.”
“Less exciting for creators than developers, but the reliability angle matters: tools like this enable the kind of reliable web automation that could power content pipelines (research, scraping, form submission) that currently break too often to trust in production.”
