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.
Toon extends your AI assistant with the ability to compress JSON data to TOON format for ~40% context savings. Use when fetching APIs, reading JSON files, or any task outputting structured data. Pipe any output through `toon` - JSON gets compressed, non-JSON passes through unchanged. 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 Toon as its underlying capability.
Toon 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 Toon 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.
Getting started with Toon takes about two minutes. Place the skill at `~/.claude/skills/toon/` (personal, all projects) or `.claude/skills/toon/` (project-specific), then restart your AI client. From that point, typing `/toon` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.
Toon has been installed 1,651 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. The source code is open on GitHub β you can inspect it, contribute fixes, or fork it to adapt the skill for your specific setup. 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/toon/ for personal use (all projects), or .claude/skills/toon/ for project-specific use. Restart your AI client, then invoke with /toon or let the AI discover it automatically.
Toon supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
Toon is free to install. Check the repository for licensing information.
