What this question tests
AI and technical metrics for code quality produced by an agentic coding assistant, extending beyond simple pass/fail checks.
How to approach it
- Define quality across layers: functional correctness (tests pass, no regressions), code health (follows existing style and architecture), and reviewer trust (how much rework a human needs).
- Track automated signals: percentage of Cascade-generated changes that pass the project's existing CI pipeline without modification.
- Track human-review signals: lines changed by a human reviewer after the agent's output, as a proxy for how close to done the work was.
- Track downstream signals: bug and rollback rate specifically tied to agent-authored changes over the following weeks.
- Combine into a composite quality score tracked over time to evaluate whether model or prompting changes improve real output quality.
- Segment by task type, since a simple refactor and a multi-file feature addition have very different baseline quality expectations.
What a strong answer includes
- Defines quality with concrete, checkable criteria across automated, human, and downstream layers.
- Uses post-generation human edit volume as a practical, hard-to-game proxy for closeness to production-ready.
- Adds downstream bug and rollback tracking to catch issues that pass initial review but surface later.
- Segments by task complexity to avoid a misleading blended score.
- Frames the composite score as a feedback tool for improving Cascade over time, not just a static report.
Common mistakes
- Using CI pass rate alone as the quality bar, ignoring maintainability and reviewer trust.
- Not segmenting by task complexity, which skews the aggregate quality number.
Likely follow-up questions
- How would you weight the different quality signals into one score?
- How would you validate the edit-volume proxy against true code quality?
- How would you use this metric to guide product improvements?
