About this project

Claude Code Skills & Plugins is an open-source library providing 388 modular instruction packages (skills), 118 agents, 7 personas, and 150 commands designed to give AI coding agents domain-specific expertise. It is compatible with 13 AI coding tools including Claude Code, OpenAI Codex, Gemini CLI, Cursor, Aider, Windsurf, and others. Each skill consists of a SKILL.md file with structured workflows, Python CLI scripts (706 total, standard library only), and reference documentation including templates and checklists. A conversion script adapts all skills to native formats for each supported tool. The library covers 20 domains: - Engineering (146 skills): architecture, frontend, backend, DevOps, security auditing, CI/CD pipeline building, RAG architecture, database design, MCP server building, observability, performance profiling, and incident response. - Product (17 skills): product management, UX research, landing pages, SaaS scaffolding, analytics. - Marketing (56 skills): content creation, SEO with Answer Engine Optimization, local SEO, CRO, LinkedIn presence, landing page generation. - Productivity (12 skills): task capture, email triage, journaling, weekly review, deep work scheduling, meeting management. - Research (15 skills): academic literature review, grant writing, patent analysis, deep research, plus enterprise Research Operations covering clinical, market, and product research. - C-Level Advisory (68 skills): full C-suite personas (CEO, CTO, CFO, CMO, etc.) with strategic advisory capabilities. - Regulatory and Compliance (28 skills): ISO 13485, MDR 2017/745, FDA, GDPR, SOC 2, CAPA, audit-readiness workflows. - Business Operations, Commercial, and Finance (20 skills): process mapping, vendor management, pricing strategy, financial analysis, SaaS metrics. - Additional domains: project management, agent launching, loop library design, and markdown-to-HTML conversion. The repository includes a skill security auditor that scans for command injection, data exfiltration, prompt injection, and supply chain risks before installation. It also provides an orchestration protocol for coordinating personas and skills across domain boundaries, with patterns for solo sprints, deep-dives, multi-agent handoffs, and sequential skill chains. Installation is available via Claude Code plugin marketplace, npx CLI for Codex, shell scripts for Gemini CLI and OpenClaw, or manual git clone. The project is MIT licensed.
