Fable 5 in Action: Redesigning a Website Frontend with Unknown Unknowns
AGI Hunt · wechat · 2026-07-05
John, author of AGIHunt, shares Anthropic engineer Thariq's Fable 5 methodology—the upper limit of Fable 5's capabilities depends on how many "unknown unknowns" you can discover. Ahead of Fable's removal from subscription plans, Thariq spent his final weekend using Fable 5 to completely overhaul the frontend of the AGIHunt website, a project he hand-coded three years ago and uses daily.
Instead of guiding the AI or constraining it to familiar territory, he let it diverge: Fable 5 read the project blueprint and existing frontend, pulled real data from the server for mocks, launched multiple agents in parallel, and generated a dozen completely different HTML design drafts, each viewable directly in a browser.
The author ultimately chose a newspaper editorial style (AI Daily Editorial), discarding the overused card-based layout for a more readable newspaper format. The piece serves as a complete engineering workflow case study for frontend redesigns using Fable 5, reducing the proportion of hand-written code from around 50% in the past to 0% today.
