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.

Benchmark your CLAUDE.md files against real PRs to see if they actually help

MDArena is an open-source benchmarking tool that answers a question every Claude Code user eventually asks: do my CLAUDE.md context files actually improve agent performance, or am I just adding tokens? It mines merged PRs from your repository, strips or injects context files, runs your actual test suite, and measures success rates with statistical significance tests. The methodology mirrors SWE-bench: use `git archive` to create history-free checkpoints so agents can't peek at future commits, detect test commands from CI/CD configs automatically, and run paired t-tests to determine whether differences are real or noise. The project was motivated by academic research showing many CLAUDE.md files reduce agent success rates by 20% while consuming more tokens. For any team investing heavily in Claude Code infrastructure, MDArena provides empirical feedback that most developers currently lack. It's a small, focused tool that solves an annoying but real problem in the emerging AI coding workflow.
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.”
“I've spent real time crafting CLAUDE.md files with no way to know if they help. A tool that uses my actual test suite against real PRs to measure context file effectiveness is exactly the feedback loop I've been missing. The `git archive` anti-cheat approach shows this was built by someone who's thought carefully about methodology.”
“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.”
“Benchmarking on merged PRs is circular — the agent is being tested on tasks that were already solved by humans, which may not reflect the actual distribution of tasks you need it for. Statistical significance from your codebase's PR history also doesn't generalize: what works in one repo will vary wildly in another. Interesting research tool, limited practical signal.”
“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.”
“Context engineering is becoming a real discipline as AI coding agents proliferate, and right now it's entirely vibes-based. MDArena represents the first step toward empirical context optimization — within two years, running something like this before shipping an agent configuration will be standard practice.”
“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.”
“The audience here is squarely developer teams with established test suites and PR histories — not a tool for creators or smaller codebases without CI/CD. The value proposition is real, but only lands for teams already deep in Claude Code infrastructure.”
