ideavim

JetBrains/ideavim/CLAUDE.md

Guidance for Claude Code when working with IdeaVim. Essential commands: - ./gradlew runIde - Start dev IntelliJ with IdeaVim - ./gradlew test -x :tests:property-tests:test -x :tests:long-running-tests:test - Run standard tests Avoid running all tests, this takes too long. It's preferred to run specific test. When running gradle tasks, use --console=plain for cleaner output without progress bars. See CONTRIBUTING.md for architecture details and a complete command list. This project uses YouTrack for issue tracking, NOT GitHub Issues. - Tickets are prefixed…

Exposed

JetBrains/Exposed/CLAUDE.md

Exposed is a lightweight ORM framework for Kotlin that provides two APIs: - DSL API: Type-safe SQL-wrapping Domain Specific Language (in exposed-core) - Works with both JDBC (exposed-jdbc) and R2DBC (exposed-r2dbc) - DAO API: Lightweight Data Access Object API - JDBC: exposed-dao - R2DBC: exposed-dao-r2dbc (experimental preview, suspending API) Tests are organized by database and dialect. Each module has database-specific test tasks:

koog / a2a

JetBrains/koog/a2a/CLAUDE.md

The A2A (Agent-to-Agent) module is a meta-module within the larger Koog project that implements a comprehensive client and server library for the A2A protocol, a standardized communication protocol for AI agents based on the specification at https://a2a-protocol.org/latest/specification/. Important: Since this is a meta-module inside a bigger root project, the Gradle wrapper executable is located one directory up. All Gradle commands must use ../gradlew when running from the a2a directory.

koog / simple-examples

JetBrains/koog/examples/simple-examples/CLAUDE.md

This is the simple-examples project within the Koog Framework repository. It contains executable examples demonstrating various AI agent patterns and capabilities, from basic calculator agents to advanced features like persistence, streaming, and agent-to-agent communication. Examples require API keys for LLM providers. Configure them via: Each example has a dedicated Gradle task: All available tasks follow the pattern runExample*. See build.gradle.kts for the complete list. This project uses Gradle composite build to depend on the parent Koog framework (settings.gradle.kts:). Changes in…

kotlinconf-app

JetBrains/kotlinconf-app/CLAUDE.md

The official KotlinConf app — a Kotlin Multiplatform project serving Android, iOS, JVM desktop, and WebAssembly clients, backed by a Ktor server. All client UI is shared via Compose Multiplatform. Android uses the app.androidApp run configuration in IDE; iOS uses KotlinConfAppScheme. Dependency Injection — Metro The app uses Metro (not Koin) for DI on the client. Key interfaces: ViewModels are registered into Metro's map multibinding: ConferenceService ConferenceService is the central app singleton. It: - Fetches AppConfig (current year) from the…

MPS

JetBrains/MPS/CLAUDE.md

This project is a mixed JetBrains MPS + plain Java/Kotlin codebase. Developers typically use two environments against the same checkout: - IntelliJ IDEA for editing, debugging, testing, and inspecting Java/Kotlin code, including code generated by MPS. - JetBrains MPS for editing languages, models, generators, and other MPS artifacts. Agents must adapt to the tools available in the current session. Use this file as the cross-environment entry point. For detailed MPS node, model, language, generator, validation, and MCP workflows, load the…

compose-hot-reload

JetBrains/compose-hot-reload/CLAUDE.md

JetBrains open-source project enabling instant UI code changes without restarting a Compose Multiplatform application. Orchestration — Communication between Gradle, the devtools, the Application, and the IDE. The devtools starts an orchestration server; all connected clients exchange broadcast messages (e.g., ReloadClassesRequest). Agent — JVM agent added at launch in hot reload mode. Runs in the premain phase and uses java.lang.instrument.Instrumentation.redefineClasses to apply class updates on demand. Runtime — A dev variant of the runtime added to the classpath in hot reload…
