Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.
Index Cards installs like any other MCP skill: drop the folder into `~/.claude/skills/index-cards/` for global access, or `.claude/skills/index-cards/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/index-cards`, or let the AI decide when it's the right tool for your request.
Index Cards has 811 installs and is part of the growing Communication skill ecosystem on DiscoverAISkills. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
Place the skill folder at ~/.claude/skills/index-cards/ for personal use (all projects), or .claude/skills/index-cards/ for project-specific use. Restart your AI client, then invoke with /index-cards or let the AI discover it automatically.
