PBE Extractor extends your AI assistant with the ability to extract invariant principles from any text β find the ideas that survive rephrasing. 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 PBE Extractor as its underlying capability.
PBE Extractor 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 PBE Extractor 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 PBE Extractor takes about two minutes. Place the skill at `~/.claude/skills/pbe-extractor/` (personal, all projects) or `.claude/skills/pbe-extractor/` (project-specific), then restart your AI client. From that point, typing `/pbe-extractor` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.
PBE Extractor has been installed 1,705 times, making it one of the more actively used skills in the Documents & Notes 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/pbe-extractor/ for personal use (all projects), or .claude/skills/pbe-extractor/ for project-specific use. Restart your AI client, then invoke with /pbe-extractor or let the AI discover it automatically.
PBE Extractor supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
PBE Extractor is free to install. Check the repository for licensing information.
