## Overview

This is a monorepo of independent open-source plugins distributed with IntelliJ-based IDEs, not one application with a shared runtime workflow. A user invokes an IDE feature—such as cloud-report highlighting, code generation, linting, or device access—and the relevant plugin handles it. The graph preserves the sampled Qodana flow and other major plugin capabilities visible in the tree and source index. Many subsystems are unsampled, so their internal connections are omitted rather than inferred.

Main entry points: [`qodana/core/src/org/jetbrains/qodana/highlight/QodanaHighlightedReportService.kt`](https://github.com/jetbrains/intellij-plugins/blob/master/qodana/core/src/org/jetbrains/qodana/highlight/QodanaHighlightedReportService.kt) (Report highlighting), [`qodana/core/src/org/jetbrains/qodana/cloud/project/QodanaCloudProjectLinkService.kt`](https://github.com/jetbrains/intellij-plugins/blob/master/qodana/core/src/org/jetbrains/qodana/cloud/project/QodanaCloudProjectLinkService.kt) (Project linking), [`javascript/eslint/src/com/intellij/lang/javascript/linter/eslint/service/ESLintBasedLanguageService.kt`](https://github.com/jetbrains/intellij-plugins/blob/master/javascript/eslint/src/com/intellij/lang/javascript/linter/eslint/service/ESLintBasedLanguageService.kt) (ESLint service), [`gauge/src/com/thoughtworks/gauge/GaugeBootstrapService.java`](https://github.com/jetbrains/intellij-plugins/blob/master/gauge/src/com/thoughtworks/gauge/GaugeBootstrapService.java) (Gauge bootstrap)
