Claude Skills Collection (Rezvani)

223 production-ready skills for Claude Code and 10 other AI coding agents. Not toy prompts — full agent plugins covering engineering, marketing, product management, compliance, and C-level advisory. Built by Alireza Rezvani, this is the largest curated skill library for AI coding tools available today. The skills span 9 domains. Engineering alone has 61 skills across two tiers: core (36 skills for architecture, frontend, backend, QA, DevOps, SecOps) and POWERFUL (25 advanced skills including agent design, RAG architecture, and security auditing). Marketing gets 43 skills organized into 7 pods — content, SEO, CRO, growth, channels, intelligence, and sales enablement. There are 28 C-level advisory skills covering full C-suite roles. Cross-tool compatibility is the real differentiator. These skills work natively with Claude Code, OpenAI Codex, Gemini CLI, Cursor, Windsurf, Aider, Kilo Code, OpenCode, Augment, Antigravity, and OpenClaw. Conversion scripts deploy across all 11 platforms simultaneously. That portability means your skill investments are not locked into one vendor. The collection includes 298 Python CLI tools using standard library only (zero external dependencies), 3 pre-configured agent personas (Startup CTO, Growth Marketer, Solo Founder), and an orchestration protocol for coordinating personas across multi-domain workflows. A built-in Security Auditor scans for malicious code, command injection, and data exfiltration before installation. 8.4K GitHub stars. MIT licensed. 612 commits on main.
