Iynx – uses your idle Cursor Composer tokens to open PRs on open source repos

I use Cursor daily with Sonnet and other frontier models, but Composer and Auto just sat unused. Those tokens expire anyway.

So I built Iynx — an autonomous agent that uses Cursor’s Composer to find trending GitHub repos, pick an open issue it can handle, write the fix, run tests in Docker, and open a real PR. Fully automated.

Two reasons I built it:

  1. I was already paying for Composer and not using it
  2. I want to contribute to open source but never have the time

Happy to answer questions about the architecture.
