Anthropic has updated Claude's system prompt with a new section that explicitly forbids reproducing song lyrics, poems, and book passages—even short excerpts, choruses, or melodies written note by note. Once Claude declines such a request, it persists in refusing even reworded or narrowed attempts within the same conversation.
Background
Anthropic regularly publishes the system prompts for its Claude consumer applications, allowing researchers and developers to track changes over time. This transparency has become a notable practice in the AI industry.
