Agent Skills by mattpocock

Agent Skills is an open-source collection of reusable skills for AI coding assistants, installable via npx skills@latest add. Created by Matt Pocock, the library extends agent capabilities across planning, development, tooling setup, and writing workflows. Each skill is a self-contained unit that can be added to your .claude directory and invoked during AI-assisted development sessions.

• Planning & Design skills — Use to-prd, to-issues, grill-me, design-an-interface, and request-refactor-plan to think through problems, generate PRDs, break work into GitHub issues, and explore interface designs before writing code.
• Development skills — Use tdd, triage-issue, improve-codebase-architecture, and others to write, refactor, and fix code using test-driven development and structured investigation workflows.
• Tooling & Setup skills — Use setup-pre-commit and git-guardrails-claude-code to configure Husky hooks, lint-staged, Prettier, and safety guardrails for dangerous git commands.
• Writing & Knowledge skills — Use write-a-skill, edit-article, ubiquitous-language, and obsidian-vault to create new skills, improve articles, extract DDD glossaries, and manage Obsidian notes.
• CLI installation — Install any skill with a single npx skills@latest add mattpocock/skills/<skill-name> command; no global install required.
• Open-source & MIT licensed — The entire repository is freely available on GitHub under the MIT License, with over 18,000 stars and 1,500 forks.
• Parallel sub-agent support — Skills like design-an-interface leverage parallel sub-agents to generate multiple radically different design options simultaneously.
• GitHub integration — Several skills (e.g., to-prd, to-issues, triage-issue) automatically file GitHub issues as part of their workflow.
