Use cases

• Identify functions with high complexity and low coverage
• Prioritize refactoring by churn frequency
• Enforce coverage and complexity gates in CI via GitHub Action

Pros

• Combines complexity and coverage into a single score
• Offers multiple integration points: CLI, MCP, and GitHub Action
• Focuses on per-function granularity for targeted improvements

Cons

• Limited adoption (1 star) suggests an immature ecosystem
• Python-only, not language-agnostic
• Requires existing coverage data to compute scores
