The 7 AI Skills Every Software Developer Should Have Installed in 2026
After testing dozens of developer-focused AI skills, these are the seven that have proven genuinely useful across different tech stacks and workflows β not just impressive demos, but tools that hold up under daily use.
Rationality extends your AI assistant with the ability to apply Critical Fallibilism to make decisions by binary testing ideas for decisive flaws, managing complexity, embracing criticism, and avoiding overreach. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly β and it will take care of the task end-to-end, using Rationality as its underlying capability.
Rationality works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) β an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Rationality once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.
Rationality installs like any other MCP skill: drop the folder into `~/.claude/skills/rationality/` for global access, or `.claude/skills/rationality/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/rationality`, or let the AI decide when it's the right tool for your request.
Rationality has been installed 2,571 times, making it one of the more actively used skills in the Developer & DevOps category. The install rate suggests it solves a real, recurring need rather than a niche edge case. 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/rationality/ for personal use (all projects), or .claude/skills/rationality/ for project-specific use. Restart your AI client, then invoke with /rationality or let the AI discover it automatically.
Rationality supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
Rationality is free to install. Check the repository for licensing information.
