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.

Euphony is an open-source, browser-based visualization tool from OpenAI that transforms raw Harmony JSON/JSONL chat data and Codex CLI session logs into interactive, filterable timelines. Paste JSON, upload a file, or point it at a public URL — Euphony auto-detects the format and renders a structured conversation view. The tool surfaces conversation-level and message-level metadata through a dedicated inspection panel, supports JMESPath-based filtering for querying large datasets, includes translation support, and can run entirely in the browser without any server dependency. For developers debugging Codex agent runs or analyzing large conversation datasets, it replaces manual JSON parsing. Euphony ships as a web component library so it can be embedded in other tools, and includes a FastAPI backend mode for remote loading and Harmony rendering. It's MIT licensed and available on GitHub at openai/euphony.
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.”
“Debugging Codex agent sessions used to mean manually reading JSON in a text editor. Euphony is what that developer experience should have always been — structured timelines, metadata inspection, and JMESPath filtering that actually works on large session files.”
“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.”
“This is purpose-built for OpenAI's Harmony format and Codex sessions, which means it's primarily useful if you're already deep in the OpenAI ecosystem. Developers using other agent frameworks get limited value here unless they adapt the format.”
“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.”
“Observability tooling for AI agents is a nascent but critical category. Euphony is a first step toward treating agent session logs with the same rigor we apply to application traces and logs — we'll see a whole category of tools like this emerge over the next two years.”
“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.”
“This is deep dev tooling with a specific niche — valuable for AI engineers but not directly applicable to creative workflows. The visualization quality is clean, but most creators won't interact with raw Harmony JSON.”
