Best alternatives to USB — Universal Skill Bridge in 2026
If you've built a custom skill or workflow for one AI coding assistant, getting it working in another usually means rewriting it from scratch — different formats, different plugin systems. USB (Universal Skill Bridge) is an open-source project that lets you define a skill once and install it into 16 different AI agent runtimes, including Claude Code, Cursor, and anything that speaks MCP. It ships a CLI (usb install/search/list/info), an SDK for building skills, a compiler that converts one skill definition into native formats per runtime, and an MCP server exposing search/install/audit tools. The project includes a catalog of 529 pre-built skills across engineering domains (audit, plan, build, script, diagnose, harden), with sha256-verified downloads and a dry-run mode to inspect a skill before installing it. It's MIT-licensed, free, and very early — beta v0.4.6 with 1 GitHub star and daily commits as of this writing.
