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.

Euphony
OpenAI's open-source browser tool for visualizing Codex and agent session logs

Euphony is an open-source browser-based visualization tool released by OpenAI for inspecting Harmony chat data and Codex agent session logs. It renders structured conversation timelines from JSON/JSONL files, clipboard data, or public URLs, making multi-step agentic sessions navigable instead of a wall of nested JSON. An optional FastAPI backend enables loading logs from remote sources. Licensed Apache 2.0. The debugging problem Euphony solves is real and growing: as AI agents execute increasingly long horizon tasks — dozens of tool calls, branching decision trees, nested sub-agent invocations — understanding what actually happened during a session becomes genuinely hard. Standard log formats are machine-readable but not human-comprehensible. Euphony renders them as interactive conversation timelines that preserve the temporal structure of the agent's reasoning. OpenAI releasing this as open-source is slightly surprising — it signals genuine investment in developer tooling transparency rather than keeping all agent debugging inside a proprietary platform. The timing aligns with broader industry pressure to make agentic systems more auditable and interpretable. For teams running Codex in production or building on OpenAI's agent APIs, Euphony is immediately useful as a debugging and post-session review tool.
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.”
“I've been pasting agent logs into jq and manually grepping for the relevant steps — Euphony makes that process human. The timeline rendering of nested tool calls is exactly what I needed to debug a multi-step research agent that was hallucinating intermediate results. The FastAPI backend for remote log loading is a nice touch for team debugging 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.”
“This is useful only if you're already deep in the OpenAI ecosystem — Harmony and Codex session formats are proprietary, so the tool doesn't generalize to Anthropic, Google, or open-weight model logs. OpenAI releasing this as open-source might be more about ecosystem lock-in than genuine altruism. Multi-framework support would make it genuinely universal.”
“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.”
“Agent observability is one of the most underinvested areas in the AI stack right now. Euphony is a step toward standardizing how we inspect and audit agentic behavior — and open-sourcing it creates pressure on the whole ecosystem to raise their tooling standards. Expect this to inspire multi-model equivalents from the community within months.”
“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 creators using Codex to automate content workflows, seeing a visual timeline of what the agent actually did versus what you expected is invaluable for improving prompts and pipeline design. The browser-based nature means you don't need to install anything — paste your log file, get instant clarity.”
