AgentsKit is a one-time-purchase kit that installs 89 specialist agents, 103 skills, and 181 slash commands directly into Claude Code. It turns a solo developer into a full product team—covering engineering, testing, security, SEO, content, and launch planning. With a single npx command, you get a private repo with agents, skills, and commands that adapt to your stack via CLAUDE.md. No subscription, lifetime updates, and it works with any Claude Code plan.
