We moved a whole codebase onto TypeScript with a fleet of subagents

The article describes how the company migrated an entire JavaScript codebase to TypeScript by deploying a fleet of AI-powered "subagents" to automate the process, significantly reducing manual effort and time compared to a traditional manual migration.

Background

The article describes an experiment by startup Cirrcles (a community-driven commerce platform). They migrated a large JavaScript codebase to TypeScript using a "fleet" of AI subagents — small, narrowly-focused AI tasks that each handled one file, coordinated by a parent agent — rather than doing it manually or with a single LLM prompt. - **TypeScript** is Microsoft's typed superset of JavaScript; it catches bugs at compile time and is standard in professional web development. - Migrating real codebases to TypeScript is tedious and error-prone (thousands of files, implicit types, edge cases). Most teams do it by hand. - Using coordinated AI subagents is novel and shows a practical, non-hypothetical use of LLMs to automate a gnarly software-engineering task, hinting at a future where developers orchestrate AI workers rather than write everything themselves.
