// Simple: inspect results
useOnTickEnd((result) => {
  console.log(`Tick ${result.tick} complete, tokens: ${result.usage?.totalTokens}`);
});

// Control continuation with boolean return
useOnTickEnd((result) => !result.text?.includes("<DONE>"));

// Control continuation with methods (includes reasons)
useOnTickEnd((result, ctx) => {
  if (result.text?.includes("<DONE>")) {
    result.stop("task-complete");
  } else {
    result.continue("still-working");
  }
});

// Async verification
useOnTickEnd(async (result) => {
  const verified = await checkWithModel(result.text);
  return !verified; // continue if not verified
});
