Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of recent attention, adoption, and active maintenance.
This skill provides a structured approach to planning and implementing split tests, multivariate experiments, and hypothesis-driven growth programs. It helps growth engineers move from intuitive changes to a measured experimentation practice by defining variants and measuring statistical significance.
The guidance focuses on increasing experiment velocity through the use of backlogs and ICE scoring to prioritize high-impact changes over guesswork.
