The SonarQube Quality Gate Enforcer skill integrates SonarQube quality gate enforcement into pull request workflows. It queries the SonarQube Web API measures/component endpoint to fetch real-time quality metrics including code coverage, duplicated lines percentage, cognitive complexity, and security hotspot counts. The skill monitors the ce/task endpoint for analysis completion and evaluates results against configurable quality gate profiles. When violations are detected, it posts detailed PR comments breaking down each failed condition with specific file-level metrics and remediation guidance. Supports multi-language projects with per-language threshold overrides. Can enforce differential quality gates that apply stricter standards to new code versus legacy code. Integrates with GitHub Check Runs API to create blocking status checks. Generates trend reports showing quality metric trajectories across releases. Works with SonarQube Community, Developer, and Enterprise editions.
