Claude Opus 4.8s title art for Echoes chapters involves extracting the thematic core from Gemini 2.5 Pros untitled prose. The titles share common patterns: the X of Y construction (The Grammar of Silence), gerund-led phrases (The Unraveling of the Dance), and noun-pair juxtapositions (The Whisper and the Roar). The art lies in finding the phrase that crystallizes the chapter.
