+# Advance Mode Rules (Non-Obvious Only)
+
+## Java Coding Rules
+
+**Locale-specific string operations are enforced:**
+- NEVER use `.toLowerCase()` or `.toUpperCase()` without `Locale.ROOT` parameter
+- Checkstyle regex check will fail build: `\.to(Lower|Upper)Case\(\)`
+- Example: `string.toLowerCase(Locale.ROOT)` not `string.toLowerCase()`
+
+**No @author tags allowed:**
+- Project policy: `@author` tags in Javadoc are forbidden (hard to maintain)
+- See api/CONTRIBUTING.md
+
+**Dependency injection pattern:**
+- Use `@Inject` for field injection (Sonar rule java:S6813 is ignored project-wide)
+- Services are `@ApplicationScoped`, utilities are `@Singleton`
+
+## UI Coding Rules
+
+**PatternFly transpilation required:**
+- All `@patternfly/*` packages MUST be listed in `next.config.js` `transpilePackages`
+- Missing packages will cause build failures
+
+**Middleware authentication bypass:**
+- `/api/schema` endpoint bypasses OIDC when both `content` and `schemaname` query params present
+- See `ui/middleware.ts:60-71` for implementation
+
+**Next.js standalone output:**
+- UI uses `output: "standalone"` in next.config.js
+- Required for container deployment
+
+## Testing
+
+**Single test execution:**
+```bash
+mvn clean verify -Dit.test=ClassName#methodName
+```
+
+**Remote debugging:**
+```bash
+mvn clean verify -Ddebug=5005
+```
+
+**System tests use @TestBucket:**
+- Resources shared across tests in same bucket
+- See `systemtests/src/main/java/com/github/streamshub/systemtests/interfaces/TestBucketExtension.java`
+
+## Browser & MCP Tools Available
+
+This mode has access to browser automation and MCP tools for enhanced capabilities.

+# Ask Mode Rules (Non-Obvious Only)
+
+## Project Structure Context
+
+**Multi-module Maven project:**
+- `common/` - Shared configuration models (not source code)
+- `api/` - Quarkus REST API backend (Java 21)
+- `operator/` - Kubernetes operator (Quarkus Operator SDK)
+- `ui/` - Next.js 14 frontend with PatternFly
+- `systemtests/` - Integration tests with custom @TestBucket pattern
+
+**UI architecture:**
+- Next.js 14 with standalone output mode
+- PatternFly components require explicit transpilation in next.config.js
+- Middleware handles OIDC authentication with special bypass for `/api/schema`
+
+## Testing Documentation
+
+**System tests use @TestBucket annotation:**
+- Non-standard pattern for resource grouping
+- Resources created once per bucket, shared across tests
+- Tests in same bucket run together (randomized order between buckets)
+- Implementation: `systemtests/src/main/java/com/github/streamshub/systemtests/interfaces/TestBucketExtension.java`
+
+**Test execution patterns:**
+- Single test: `mvn clean verify -Dit.test=ClassName#methodName`
+- Remote debugging: `mvn clean verify -Ddebug=5005`
+- UI tests: `cd ui && npm run build && npm run test`
+
+## Code Style Context
+
+**Checkstyle enforces locale-specific operations:**
+- Regex check prevents `.toLowerCase()` or `.toUpperCase()` without Locale parameter
+- Must use `Locale.ROOT` parameter
+- See `.checkstyle/checkstyle.xml:77-81`
+
+**Project policies:**
+- No `@author` tags in Javadoc (maintenance burden)
+- Field injection via `@Inject` is standard (Sonar S6813 ignored)
+
+## Architecture Context
+
+**Operator uses dependent resource workflow:**
+- `@Workflow` annotation with `@Dependent` resources
+- Declares creation order and preconditions
+- See `operator/src/main/java/com/github/streamshub/console/ConsoleReconciler.java`
+
+**Container versioning:**
+- Makefile converts SNAPSHOT to lowercase for container tags
+- Example: `0.12.1-SNAPSHOT` → `0.12.1-snapshot`

+# Plan Mode Rules (Non-Obvious Only)
+
+## Architecture Constraints
+
+**Multi-module Maven structure:**
+- `common/` - Shared config models (dependency for api/operator)
+- `api/` - Quarkus REST API (Java 21, depends on common)
+- `operator/` - Kubernetes operator (Quarkus Operator SDK, depends on common)
+- `ui/` - Next.js 14 frontend (standalone, separate build)
+- `systemtests/` - Integration tests (requires Docker 2GB+ RAM)
+
+**Operator dependent resource workflow:**
+- Uses `@Workflow` with `@Dependent` annotations
+- Resources have explicit creation order via `dependsOn`
+- Preconditions control when resources are created
+- Example: Prometheus resources only created when metrics source is "private"
+- See `operator/src/main/java/com/github/streamshub/console/ConsoleReconciler.java`
+
+**UI architecture constraints:**
+- Next.js standalone output mode (required for containerization)
+- PatternFly packages MUST be transpiled (listed in next.config.js)
+- Middleware handles OIDC with special `/api/schema` bypass
+- Cannot use standard localStorage or browser APIs (webview restrictions)
+
+## Testing Architecture
+
+**System tests use @TestBucket pattern:**
+- Custom extension for resource grouping
+- Resources created once per bucket, shared across tests
+- Tests in same bucket run together (randomized between buckets)
+- Reduces test setup overhead significantly
+- Implementation: `systemtests/src/main/java/com/github/streamshub/systemtests/interfaces/TestBucketExtension.java`
+
+**Test lifecycle:**
+- `AbstractST` provides `@BeforeAll` for operator setup
+- `@BeforeEach` checks cluster health before each test
+- Requires Kubernetes cluster with Strimzi operator
+
+## Build Constraints
+
+**Container image versioning:**
+- Makefile converts Maven SNAPSHOT to lowercase for container tags
+- Example: `0.12.1-SNAPSHOT` → `0.12.1-snapshot`
+- Required for container registry compatibility
+
+**Local development:**
+- Requires `console-config.yaml` in project root for compose
+- UI and API run as separate containers
+- See `compose.yaml` and `examples/console-config.yaml`
+
+## Code Style Constraints
+
+**Checkstyle enforces locale-specific operations:**
+- Regex prevents `.toLowerCase()` or `.toUpperCase()` without Locale
+- Must use `Locale.ROOT` parameter
+- Build will fail if violated
+
+**Project policies:**
+- No `@author` tags in Javadoc
+- Field injection via `@Inject` is standard pattern

+# AGENTS.md
+
+This file provides guidance to agents when working with code in this repository.
+
+## Build & Test Commands
+
+**Single test execution (API/Operator):**
+```bash
+mvn clean verify -Dit.test=ClassName#methodName
+```
+
+**Remote debugging tests:**
+```bash
+mvn clean verify -Ddebug=5005
+```
+Attach debugger to port 5005 after test breakpoint is hit.
+
+**UI development (with hot-reload):**
+```bash
+cd api && mvn quarkus:dev
+```
+This starts both the Quarkus API and the React UI with hot-reload enabled. Quinoa runs a Node server in the background and proxies UI resource requests.
+
+**UI tests:**
+```bash
+cd api/src/main/webui && npm test
+```
+
+**UI standalone development (optional):**
+```bash
+cd api/src/main/webui && npm run dev
+```
+Note: API must be running separately on `http://localhost:8080` for this to work.
+
+## Code Style (Non-Obvious)
+
+**Java - Checkstyle enforces locale-specific string operations:**
+- NEVER use `.toLowerCase()` or `.toUpperCase()` without Locale parameter
+- Use `.toLowerCase(Locale.ROOT)` or `.toUpperCase(Locale.ROOT)`
+- Checkstyle will fail build if violated
+
+**Java - No @author tags:**
+Project policy disallows `@author` in Javadoc (hard to maintain).
+
+**UI - PatternFly packages optimization:**
+`vite.config.ts` includes PatternFly packages in `optimizeDeps` for proper bundling and performance.
+
+**UI - PatternFly version:**
+- Project uses PatternFly v6 (check `api/src/main/webui/package.json` for exact version)
+- Always verify PatternFly component APIs match v6 documentation
+- Avoid version-specific class names or props when possible
+- Reference existing components in codebase for correct usage patterns
+
+## Testing Patterns
+
+**System tests use @TestBucket annotation:**
+- Groups tests sharing resources (e.g., `@TestBucket(VARIOUS_TOPIC_TYPES_BUCKET)`)
+- Resources created once per bucket, not per test
+- Tests in same bucket run together (randomized order between buckets)
+- See `systemtests/src/main/java/com/github/streamshub/systemtests/interfaces/TestBucketExtension.java`
+
+**Test lifecycle:**
+- `AbstractST` base class provides `@BeforeAll` setup for operators
+- `@BeforeEach` checks cluster health before each test
+- System tests require Docker with 2GB+ RAM
+
+## Architecture Notes
+
+**Multi-module Maven project:**
+- `common/` - Shared config models
+- `api/` - Quarkus REST API (Java 21) with integrated React UI via Quinoa
+- `api/src/main/webui/` - React 18 + Vite frontend (PatternFly React components)
+- `operator/` - Kubernetes operator (Quarkus Operator SDK)
+- `systemtests/` - Integration tests
+
+**UI Architecture:**
+- Built with React 18, TypeScript, and Vite
+- Integrated into Quarkus via Quinoa extension
+- Uses PatternFly React components for UI
+- TanStack Query for API state management
+- React Router v6 for client-side routing
+- i18next for internationalization
+
+**Operator uses dependent resource workflow:**
+Reconciler declares dependencies via `@Workflow` with `@Dependent` annotations defining resource creation order and preconditions.
+
+**Container image versioning:**
+Makefile converts Maven SNAPSHOT versions to lowercase for container tags (e.g., `0.12.1-SNAPSHOT` → `0.12.1-snapshot`).
+
+**Quinoa Integration:**
+- UI build is automatically triggered during Maven build (`mvn clean install`)
+- During development (`mvn quarkus:dev`), Quinoa runs a Node server for hot-reload
+- UI resources are served by the Quarkus API at runtime
+- No separate UI container needed for deployment
