+- **`cli/`** - Standalone CLI package
+- **`packages/`** - Shared packages (`types`, `ipc`, `telemetry`, `cloud`)
+- **`jetbrains/`** - JetBrains plugin (Kotlin + Node.js host)
+- **`apps/`** - E2E tests, Storybook, docs
+
+Key source directories:
+- `src/api/providers/` - AI provider implementations (50+ providers)
+- `src/core/tools/` - Tool implementations (ReadFile, ApplyDiff, ExecuteCommand, etc.)
+- `src/services/` - Services (MCP, browser, checkpoints, code-index)
