v2.0.0MIT

The Duolingo playbook as agent skills — retention, streaks, gamification, learning science, curriculum, efficacy measurement, metrics, experimentation, growth, brand, voice, culture, hiring, platform and mobile engineering, observability, and LLM feature design. Distilled from 750 posts on blog.duolingo.com plus the Duolingo Handbook and Design System. Start at the /duolingo router; design and UI craft routes out to design-engineering.

Design a shipped feature so it actually gets used — lower the cost of starting, give one obvious next step, and plan for the moment the user stalls, is embarrassed, is in the wrong place, or gets it wrong. Draws the pattern library from Duolingo's public record (path redesign, guided calls, Game Review, Practice Hub, Friends Quests, Year in Review migration) and restates each move for any product. Use when you hear "we shipped it and nobody uses it", "users say they're not sure they're doing it right", "should this be free choice or a fixed order", "our activation is bad", "people open the feature and bounce", "how do we onboard without a tutorial", "should we gate the recap", "nobody finishes the session", "users are abusing this feature", or "power users keep asking for a way to skip ahead".
