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.
Agent Hardening extends your AI assistant with the ability to test your agent's input sanitization against common injection attacks. Runs self-contained checks using synthetic test data only β no local files are accessed. 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 Agent Hardening as its underlying capability.
Agent Hardening 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 Agent Hardening 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.
To install Agent Hardening, copy the skill folder to `~/.claude/skills/agent-hardening/` for use across all your projects, or `.claude/skills/agent-hardening/` for a single project. Restart Claude and the skill is immediately active β invoke it with `/agent-hardening` or just describe your goal and the AI will pick it up automatically.
Agent Hardening has been installed 1,060 times, making it one of the more actively used skills in the Data & Analytics 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/agent-hardening/ for personal use (all projects), or .claude/skills/agent-hardening/ for project-specific use. Restart your AI client, then invoke with /agent-hardening or let the AI discover it automatically.
Agent Hardening supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
