Buck2 Target Determination

概要

Streamline development cycles within Buck2 monorepos by pinpointing exactly which targets are impacted by code changes. This skill leverages the quicktd tool and Jujutsu (jj) revsets to compute file deltas and map them to the target graph, allowing for incremental testing and building that can be significantly faster than full repository scans. Whether optimizing local pre-commit checks or refining CI/CD pipelines, it provides the precise command patterns and troubleshooting guidance needed to handle large-scale target lists efficiently using at-file syntax and the quicktd_helper script.
