Code Quality Scoring

A vendor-neutral framework for quantifying and communicating software quality at the application and portfolio level. Most quality skills tell you how to fix one finding; this skill tells you how to score an entire codebase, estimate the cost of its debt, and explain both to people who do not read code.

Source note: The scoring frameworks below are derived from CAST Highlight's code quality indicators and methodology (https://doc.casthighlight.com/). They are paraphrased and re-expressed as a vendor-neutral model. Threshold bands and debt-density figures are CAST's proprietary calibration from their AppMarq benchmark dataset; they are presented here as attributed reference ranges, not as universal standards. Where CAST defers to open standards (COCOMO II for effort, SPDX/choosealicense for licenses, CWE/CVE for security), cite those primary sources.

When to Use This Skill

Use it when the question is "how healthy is this codebase, and what should we do first?" — for example:
