Orchestrates end-to-end interview preparation for senior ML/AI engineers targeting Anthropic and peer companies. Use for prep timeline generation, story coherence across rounds, mock scheduling, and debrief analysis. Activate on "interview prep", "interview loop", "Anthropic interview", "prep timeline". NOT for resume writing, career narratives, or individual round-type practice.
Analyze existing code and write comprehensive unit and integration tests for it. Detects the test framework, identifies untested code paths, and generates tests with proper mocking, edge cases, and assertions. Use when the user asks to add tests, improve coverage, or test a specific module.
Use when jest testing patterns including unit tests, mocks, spies, snapshots, and assertion techniques for comprehensive test coverage.
TDD London School workflow -- mock-first, outside-in test development
Sketch a UI design as a throwaway `.openui` file in `docs/prototype/` for the developer to render live in the Genui VS Code extension. Use when the user wants to see a design, sketch a screen, mock up a layout, compare a few options, or says "genui this", "sketch a [page]", "mock up [thing]", "let me see a few options", "prototype this design", "draft a UI". This is specifically for visual UI mockups rendered by the Genui extension, not terminal logic prototyping.
Master iOS testing - XCTest, UI testing, mocking, debugging, performance
Test authenticated routes in the your project using cookie-based authentication. Use this skill when testing API endpoints, validating route functionality, or debugging authentication issues. Includes patterns for using test-auth-route.js and mock authentication.
Generates interactive HTML visualizations — UI mockups, ERDs, flowcharts, charts, slides, architecture diagrams, dashboards, timelines, mindmaps, kanban boards, tables, wireframes. Use when the user asks to visualize, mock up, diagram, chart, create ERD, generate slides, architecture diagram, dashboard, timeline, mindmap, kanban, table, wireframe, or interactive HTML.
Use vision models to self-review screenshots against design intent. Catches spacing issues, alignment problems, color inconsistencies, responsive bugs, and accessibility gaps. Use when reviewing designs, comparing implementations to mockups, or doing pre-ship QA.
Create factory fixture patterns for customizable test setup with variations. Use when building reusable test fixtures with multiple configurations, creating parameterizable mocks, or implementing test data builders. Works with pytest fixtures, mock objects, and test utilities. Enables DRY test setup while maintaining flexibility for edge cases.
Use when you need to write or improve integration tests — including Testcontainers with @ServiceConnection, @DataJdbcTest persistence slices, TestRestTemplate or MockMvcTester for HTTP, data isolation, and container lifecycle management for Spring Boot 4.0.x. Part of the skills-for-java project
PHPUnit testing best practices and conventions guide. This skill should be used when writing, reviewing, or refactoring PHPUnit tests to ensure consistent, maintainable, and effective test suites. Triggers on tasks involving test creation, test refactoring, test configuration, code coverage, data providers, mocking, or PHPUnit XML configuration.
