I simply ask Claude Sonnet, using claudecode, to use opencode. That's it! Example:

  We need to clean up code lint and format errors across multiple files. Check which files are affected using cargo commands. Please use opencode, a coding agent that is installed. Use `opencode run <prompt>` to pass in a per-file prompt to opencode, wait for it to finish, check and ask again if needed, then move to next file. Do not work on files yourself.
