Validates operator chart contribution practices (helm template, ct lint, docs generation) before committing changes.

Captures a team convention or best practice and adds it to the appropriate .claude/rules/ or .claude/agents/ file

UI/UX design intelligence with searchable database

Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".

UI/UX design intelligence. 50 styles, 21 palettes, 50 font pairings, 20 charts, 9 stacks.

Comprehensive guide to Antigravity Manager architecture, workflows, and development. Use this to understand how to work on the project.

Assistance with triage of unprioritized issues. Use when the user asks for help with triage.

Ensure the plugin remains compatible with the latest IntelliJ Platform releases and EAP (Early Access Program) builds.

Eliminate plugin verification warnings and errors (Internal API usage, Override-only API usage, etc.) identified by ./gradlew verifyPlugin.

Remove support for an older IntelliJ Platform / Android Studio version from the project and clean up obsolete code, baselines, and CI configurations.

Optimize memory usage, consistency, and performance by migrating standard Java/Kotlin classes to IntelliJ's specialized com.intellij.util implementations.

Perform a pedantic, multi-perspective code review on the current diff or git changes against the styleguide and software engineering best practices.

Reduce plugin size by scanning resources/icons and removing unreferenced assets.

Reduce technical debt and improve code quality by systematically resolving static analysis warnings.

Prevent UI freezes and ensure a responsive user experience by validating threading rules and migrating blocking calls off the Event Dispatch Thread (EDT).

Optimize plugin size and security by removing unused dependencies and updating outdated libraries.

Ensure the plugin's custom UI components are accessible to users with screen readers and other assistive technologies.

Add a new unit test for a class that currently lacks one or add a new test case to an existing test file, verifying improvement with Kover.

Use when writing, editing, refactoring, or debugging tests anywhere under `tests/**` (unit, integration, or end-to-end); authoring NUnit 4 test classes (`*Test`, `*IntegrationTest`); using NSubstitute mocks, AutoFixture with `[AutoMockData]` / `[InlineAutoMockData]` / `[Frozen]`, or AwesomeAssertions (NOT FluentAssertions); working with `CliIntegrationFixture`, `IntegrationTestFixture`, `MockFileSystem`, `TestableLogger`, `NUnitAnsiConsole`, or `New*` factory helpers; adding or updating E2E fixtures under `tests/Recyclarr.EndToEndTests/Fixtures/` (`recyclarr.yml`, `settings.yml`, `custom-formats-*`, `trash-guides-override/`); running `Run-E2ETests.ps1` or `scripts/coverage.py`; investigating flaky tests, coverage gaps, or Testcontainers setup. Triggers on phrases like "write a test", "fix this test", "improve coverage", "add an E2E case", "mock this dependency", or any edit to `*.Tests.csproj` or files under `tests/**`.

Use when writing, editing, or reviewing C# code that uses System.Reactive (Rx.NET); working with `IObservable`, `IObserver`, `Subject`, `BehaviorSubject`, `ReplaySubject`, or `AsyncSubject`; composing operators like `Select`, `Where`, `Merge`, `Switch`, `Publish`, `RefCount`, `Catch`, `Retry`, `ObserveOn`, or `SubscribeOn`; managing subscription lifecycle with `CompositeDisposable`, `SerialDisposable`, or `DisposeWith`; testing time-dependent reactive code with `TestScheduler` from `Microsoft.Reactive.Testing`; designing hot vs cold observables or enforcing the Rx serial-notification contract. Triggers on phrases like "observable stream", "reactive pipeline", "Rx.NET", "subject leak", "OnNext on wrong thread", "test scheduler", or edits touching files that import `System.Reactive`. Do NOT use for plain `IEnumerable` LINQ, `IAsyncEnumerable`, or TPL `Task`-based async.
