Building a better Bugbot

This post details the evolution of Bugbot from a prototype to a production system, highlighting the transition to a fully agentic design. Key contributions include the development of a "resolution rate" metric for quantitative evaluation, the implementation of a multi-pass, majority-voting approach for initial bug detection, and the integration of codebase-specific rules. The agentic architecture enabled more aggressive prompting and dynamic context utilization, leading to significant improvements in bug detection rates and a doubling of resolved bugs per PR. The post also introduces Bugbot Autofix for automatic bug fixing and future plans for code execution verification.
