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.

Structured Output Benchmark
The benchmark that tests whether LLMs get JSON values right, not just syntax

Interfaze's Structured Output Benchmark (SOB) exposes a gap that has been quietly breaking production AI pipelines: models can produce syntactically valid JSON while getting the actual values wrong. SOB measures value accuracy across 21 models using 5,000 text passages, 209 OCR documents, and 115 meeting transcripts — scoring each on seven metrics including value accuracy, faithfulness (grounding vs. hallucination), type safety, and perfect-response rate. The benchmark reveals some sobering findings. Even top models like GPT-5.4 and Claude Sonnet 4.6 achieve ~83% on text but drop to 67% on images and only 23.7% on audio. No single model dominates all modalities — GPT-5.4, GLM-4.7, Qwen3.5-35B, and Gemini 2.5 Flash cluster within one point of each other on text. Perfect response rates (all seven metrics correct) rarely exceed 50% for even the best performers. For developers building data extraction pipelines, agents that read invoices, or any system where "correct JSON" means more than syntactically valid JSON, this is required reading. The dataset is on Hugging Face, the paper is on arXiv, and the playground lets you test your own model's structured output capability directly.
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.”
“This is the benchmark I've been waiting for. 'Valid JSON' is table stakes — the real question is whether field values are correct. This plugs a genuine gap in how we evaluate extraction pipelines.”
“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 23.7% audio accuracy stat sounds alarming but the test data is text-normalized before scoring, meaning ASR errors are excluded. It's a better benchmark than most but the methodology choices deserve more scrutiny before you rely on it for vendor selection.”
“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.”
“No universal winner across modalities is the real story here. As agentic systems increasingly handle mixed-media inputs, this exposes that model selection needs to be task-specific. Benchmarks like SOB are how the industry gets smarter about that.”
“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.”
“For anyone automating content workflows that extract structured data from documents, briefs, or meeting recordings, this tells you which model to actually trust for each media type. Genuinely useful before you commit to an architecture.”
