Skills is a curated library of AI agent prompts and workflows for real software engineering, created by TypeScript educator Matt Pocock. The project trended to 28,000 GitHub stars with its blunt tagline: "Agent skills for real engineers — not vibe coding." It's a deliberate pushback against chaos-first AI coding in favor of structured, methodical engineering. The library organizes into four categories: Planning & Design (to-prd for converting conversations into PRDs, grill-me for stress-testing plans), Development (tdd for test-driven AI assistance, triage-issue for bug investigation), Tooling & Setup (pre-commit hooks, git safety guards), and Writing & Knowledge (documentation utilities, Obsidian integration). Each skill installs with a single npx command — npx skills@latest add mattpocock/skills/tdd — and plugs into Claude agent setups. With 28,000 stars and 2,200 forks after trending on GitHub on April 27, 2026, Skills has clearly struck a nerve. It's as much a cultural statement as a product: AI coding tools should be used deliberately, with tests, with planning, and with guardrails. The TDD and triage-issue skills address real gaps in how current AI coding agents handle existing codebases rather than greenfield projects.

OpenAI's API provides access to GPT-4, DALL-E, Whisper, TTS, and embeddings. The largest AI API ecosystem with the most third-party integrations.
Reviewer scorecard
“The tdd skill alone is worth the install. Watching a Claude agent plan tests before writing implementation is exactly how I want AI to assist me. Matt's framing of 'real engineering vs. vibe coding' is the right cultural correction for 2026.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“These are sophisticated markdown prompts, not magic. If you're already a disciplined engineer, the skills add ceremony without much acceleration. The 28K stars partly reflect Matt's Twitter following — evaluate the actual skills before star-chasing.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“Community-curated skill libraries installed via package managers will become standard infrastructure — as natural as installing a linting config. Skills is the early prototype of a skills ecosystem that will matter at scale.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
“The writing and knowledge skills are underrated. The article-editing and Obsidian integration skills bring structured AI assistance to documentation workflows that most agent tools ignore entirely. Install even if you're not primarily a developer.”
