Does this break your code?

Run this in your project. It compares both releases against the names your code actually imports, locally, with no account and nothing sent to lurq:

npx lurqrun check-upgrade --upgrade fast-check@2.25.0..3.23.2

To have your coding agent check upgrades like this before it writes them, connect lurq to Claude Code, Cursor, VS Code or Codex:

npx lurqrun
