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.
Prompt Injection Guard extends your AI assistant with the ability to prompt injection defense. Detect and block malicious prompts, protect system instructions, sanitize user input. 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 Prompt Injection Guard as its underlying capability.
Prompt Injection Guard 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 Prompt Injection Guard 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 Prompt Injection Guard takes about two minutes. Place the skill at `~/.claude/skills/prompt-injection-guard/` (personal, all projects) or `.claude/skills/prompt-injection-guard/` (project-specific), then restart your AI client. From that point, typing `/prompt-injection-guard` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.
Prompt Injection Guard has been installed 7,612 times, making it one of the more actively used skills in the AI Agent & Automation 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/prompt-injection-guard/ for personal use (all projects), or .claude/skills/prompt-injection-guard/ for project-specific use. Restart your AI client, then invoke with /prompt-injection-guard or let the AI discover it automatically.
Prompt Injection Guard supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
Prompt Injection Guard is free to install. Check the repository for licensing information.
