Beyond Productivity: Scoring Claude Code Effectiveness with Anthropic's Research Data

Most developers using Claude Code lack visibility into whether they're using it effectively—and productivity isn't the same as effectiveness. This new scoring tool, based on Anthropic's analysis of 132 engineers and 200,000 sessions, provides the first concrete benchmark for AI collaboration quality. The underlying research reveals that better engineers give Claude more autonomy while steering less, enabling 27% more work that wouldn't otherwise happen.
