Building a C compiler with a team of parallel Claudes

This post details the development of an 'agent team' harness that enabled 16 Claude instances to autonomously build a C compiler capable of compiling the Linux kernel. Key contributions include: a loop-based harness for sustained autonomous progress, a synchronization algorithm using Git locks to manage parallel task execution, and a robust testing environment with continuous integration to prevent regressions. The post also describes strategies for handling context window limitations, time blindness, and the challenge of large, monolithic tasks by introducing an oracle-based comparison with GCC for compiler development. Specialization of agents for tasks like code duplication, performance optimization, and documentation was also demonstrated.
