Switching between mcoding agents has its own problems Skills go stale, MCP servers drift, and every new tool demands the same setup all over again. skills-sync manages your skills, MCP servers, and config from one workspace, then syncs them across Claude, Codex, Gemini, Cursor, and Copilot automatically. Essentially 1 command to install an MCP everywhere. 1 command to refresh stale skills. 1 command to detect drift and fix it.
