GitHubEngineeringRepository Health Score
Repository Health Score is a composite metric that evaluates key health indicators for a GitHub repository, including documentation completeness, test coverage, CI configuration, dependency freshness, branch protection rules, and recent maintenance activity. It provides a single number for comparing repository maturity across an organisation.

Full guide: definition, formula, and benchmarksWhy Repository Health Score matters for GitHub users
Organisations with dozens or hundreds of repositories need a way to prioritise maintenance investment. A health score surfaces repositories that are well-maintained and those that are accumulating risk through neglect.
For GitHub teams, the health score helps platform teams identify repositories missing branch protection, lacking CI configuration, or falling behind on dependency updates - any of which could become a security or reliability incident.

Understand and act on Repository Health Score with KPI Tree
Aggregate repository metadata from the GitHub API in your warehouse and define a weighted composite score in KPI Tree. Place it at the top of a repository-level metric tree with components like coverage, dependency age, and documentation quality as child nodes.
Assign RACI ownership to repository maintainers and configure quarterly reviews where low-scoring repositories are triaged for improvement.

Code Quality Trend Analysis
EngineeringCode Quality Trend Analysis aggregates signals such as linting violations, cyclomatic complexity, code duplication, and static-analysis findings over time. It provides a longitudinal view of code health across repositories. Consistent improvement indicates maturing engineering practices.
View metricCode Coverage Trend
EngineeringCode Coverage = Lines Covered by Tests / Total Lines of Code × 100
Code Coverage Trend tracks the percentage of code exercised by automated tests over time, measured per commit or release. It highlights whether new code is being adequately tested and whether coverage is improving or regressing. Sustained downward trends signal growing risk.
View metricSecurity Vulnerability Trends
EngineeringSecurity Vulnerability Trends tracks the number, severity, and type of security vulnerabilities discovered across repositories over time. It encompasses Dependabot alerts, code scanning findings, and secret scanning detections. Improving trends indicate maturing security practices and proactive dependency management.
View metricTechnical Debt Accumulation
EngineeringTechnical Debt Accumulation measures the rate at which technical debt grows across a codebase, using proxies such as TODO/FIXME comment count, aged open issues labelled as tech-debt, increasing cyclomatic complexity, and dependency staleness. Rising accumulation signals that short-term trade-offs are compounding into long-term burden.
