Building a C compiler with a team of parallel Claudes

What this post added

This post introduces the concept of 'agent teams' for autonomous software development, detailing a specific experiment where 16 Claude instances built a C compiler. It describes the technical implementation of a harness for these teams, including an infinite loop structure, a file-locking synchronization algorithm for parallel task management, and strategies for designing tests and feedback mechanisms to guide autonomous progress. It also highlights challenges like context window pollution, time blindness, and overcoming monolithic task dependencies, introducing a GCC-based oracle for parallel debugging of large codebases. The post also touches on specialization within agent teams and benchmarks the capabilities of different Claude model versions on this complex task.
