The author name "Named by [YeonGyu Kim]" in the Sisyphus role section
causes LLMs to sometimes infer Korean language output, even when the
user's locale is en-US.
This happens because the model sees a Korean name in the system prompt
and may interpret it as a signal to respond in Korean.
Removing the author attribution from the runtime prompt fixes this issue.
The attribution is preserved in README, LICENSE, and package.json.
