The Mechanics of Oversight

• The build process for Elsa Hunison—a deaf-blind Hugo-winning author launching her new book, Dear Blind Lady, in October 2026—utilized Claude Fable 5 as a foreman that never wrote code, but instead managed cheaper worker models through 34 distinct tasks.3:44
• The system corrected four significant failure modes during the build, including hallucinated quote retrieval, accessibility-harming layout shortcuts, and a CSS dark-mode bug in the pre-order button introduced by the 'boss' model itself.8:56
• Verification was not based on model trust; independent checker agents validated every task against live browser environments, catching 12 tasks for rework before they reached the finished site.7:12
• Disputes flowed in both directions: a checker falsely rejected legitimate short news posts as too brief, which were subsequently validated after an escalation to the boss model.10:36

Quality and Cost

• The project was guided by 171 protected passages preserved verbatim from the original site and a 14-point accessibility constitution centered on a blind-reader persona named 'Maya,' who requires navigable headings and precise image descriptions.12:55
• The system dramatically shifted the economic profile of the work: while a single-agent build was estimated to cost over $85, the multi-agent orchestration was completed for roughly $8, demonstrating a 10x savings on cloud compute tokens.5:57
