Testing & Quality skills
Browse reusable Agent Skills, each with a clear purpose and practical guidance.
engine-debugging
Run Dagger repo tests and debug Dagger engine, core, dagql, filesync, cache, CI trace, panic, hang, leak, and performance issues. Use whenever an agent needs to run tests, choose a test command, or interpret test output in this repository, even before a failure is diagnosed; also use for engine-dev tests, Dagger Cloud trace replay, debug endpoints or pprof, goroutine dumps, panics, hangs, leaks, performance issues, and /debug/dagql/cache snapshots.
clang-tidy-check
Run clang-tidy on newly added/modified BE C++ code
doris-docker-regression
Run Doris docker-based regression tests from a clean package
docs-e2e-tests
Write or update Playwright example.spec.ts tests for AG Grid documentation examples, then run them with docs-e2e.sh to verify. Use when asked to write, add, extend, or fix e2e/Playwright tests for a docs page or a specific example, or when a docs example needs meaningful (non-placeholder) test assertions.
playwright-testing
Use when writing Playwright tests, fixing flaky tests, debugging failures, implementing Page Object Model, configuring CI/CD, optimizing performance, mocking APIs, handling authentication or OAuth, testing accessibility (axe-core), file uploads/downloads, date/time mocking, WebSockets, geolocation, permissions, multi-tab/popup flows, mobile/responsive layouts, touch gestures, GraphQL, error handling, offline mode, multi-user collaboration, third-party services (payments, email verification), console error monitoring, global setup/teardown, test annotations (skip, fixme, slow), test tags (@smoke, @fast, @critical, filtering with --grep), project dependencies, security testing (XSS, CSRF, auth), performance budgets (Web Vitals, Lighthouse), iframes, component testing, canvas/WebGL, service workers/PWA, test coverage, i18n/localization, Electron apps, or browser extension testing. Covers E2E, component, API, visual, accessibility, security, Electron, and extension testing.
create-mre
Create or reduce a Minimally Reproducible Example (MRE) for a Nuitka bug from a larger reproducer. Use when the user asks to isolate, minimize, or shrink Python code while preserving a compiler, optimization, or packaging issue.
agui-dotnet-code-review
Review C#/.NET code changes to the AG-UI .NET SDK (sdks/dotnet/) against its specific conventions and architectural rules — AOT serialization, the "no ASP.NET in src/" boundary, the PublicAPI analyzer workflow, wire compatibility with the TypeScript reference, and the house style (sealed/no-records/ConfigureAwait). Runs a phased, rule-by-rule review. USE FOR: reviewing a PR, diff, or branch that touches sdks/dotnet/; checking a new event/message type; verifying serialization, package placement, or public-API changes in the .NET SDK. DO NOT USE FOR: generic C# style nits already enforced by analyzers/EditorConfig; reviewing the TypeScript SDK (sdks/typescript/) or Python SDK (sdks/python/); writing new features (only flag violations, never rewrite code).
agui-dotnet-cross-language-tests
Author cross-language interop tests that verify the AG-UI .NET SDK is wire-compatible with the TypeScript SDK — a Vitest TS client driving a C# CrossLanguage.TestServer over HTTP, both directions, including protobuf byte-parity against @ag-ui/proto. USE FOR: adding or modifying cross-language interop coverage, CrossLanguage.TestServer routes, the CrossLanguage.Vitest suite, protobuf wire parity tests, TS-client-to-C#-server or C#-client-to-TS-server scenarios. DO NOT USE FOR: .NET-only unit tests (use agui-dotnet-unit-tests), ASP.NET Core hosting integration tests (use agui-dotnet-integration-tests).
agui-dotnet-integration-tests
Write integration tests for the AG-UI .NET SDK. USE FOR: adding a new AG-UI event type and covering it end-to-end, testing SSE or protobuf streaming through the hosting pipeline, verifying AGUIChatClient maps events to ChatResponseUpdate, multi-turn conversation tests, parameterizing a test over Json/Protobuf transports, adding or updating a GettingStarted sample replay/Verify snapshot. Covers: WebApplicationFactory + DelegatingStreamingChatClient setup, IChatClient-based assertions with Assert.Collection, TransportFormat [Theory] (Json/Protobuf), recording/replay capture infrastructure, and the 8-capture-point Verify baselines. DO NOT USE FOR: unit tests of event serialization (use tests/AGUI.Abstractions.UnitTests) or stream-conversion unit tests (use tests/AGUI.Server.UnitTests).
