Summary
The article discusses how Meta leveraged AI to enhance the understanding and navigation of its large-scale data pipelines, which span multiple repositories and programming languages. By implementing a pre-compute engine with specialized AI agents, they were able to document tribal knowledge that was previously undocumented, resulting in a significant increase in AI context coverage and efficiency. The approach involved a structured orchestration of tasks among various AI agents to create concise context files that guide developers in navigating complex codebases. The system is designed to maintain itself, ensuring that the context remains relevant and up-to-date.
