Multi-Agent Dev in Action: Transforming a Classical Music App
Ok_Significance_9109 · reddit · 2026-07-20
An indie developer shared their 8-year journey of building an iPad sheet music page-turner app. Initially mediocre, its performance surged after integrating Claude Opus to test various algorithmic approaches.
Recently, they adopted a multi-agent collaboration model for further optimization: using Fable as a "supervisor" to identify over 50 deep code issues, themselves as the "domain expert" for business logic, and Opus as the "executor" for code refactoring. The app eventually reached highly stable, performance-grade reliability. At the end of the task, Fable even auto-generated a warm farewell message, praising the efficiency of this collaborative model and the developer's domain expertise.
