Use this skill when implementing data validation, data quality monitoring, data lineage tracking, data contracts, or Great Expectations test suites. Triggers on schema validation, data profiling, freshness checks, row-count anomalies, column drift, expectation suites, contract testing between producers and consumers, lineage graphs, data observability, and any task requiring data integrity enforcement across pipelines.
Use this skill when writing Playwright tests, implementing visual regression, testing APIs, or automating browser interactions. Triggers on Playwright, page object model, browser automation, visual regression, API testing with Playwright, codegen, trace viewer, and any task requiring Playwright test automation.
Use this skill when deploying ML models to production, setting up model monitoring, implementing A/B testing for models, or managing feature stores. Triggers on model deployment, model serving, ML pipelines, feature engineering, model versioning, data drift detection, model registry, experiment tracking, and any task requiring machine learning operations infrastructure.
Use this skill when implementing structured data markup using JSON-LD and Schema.org vocabulary for rich search results. Triggers on adding schema markup for FAQ, HowTo, Product, Article, Breadcrumb, Organization, LocalBusiness, Event, Recipe, or any Schema.org type. Covers JSON-LD implementation, Google Rich Results eligibility, validation testing, and framework integration (Next.js, Nuxt, Astro).
Spring Modulith for modular architecture in Spring Boot 3.x. Covers module structure, API vs internal packages, inter-module events, module testing, documentation generation, and observability. USE WHEN: user mentions "spring modulith", "modular monolith", "@ApplicationModule", "module boundaries", "inter-module events", "@ApplicationModuleTest", "modular architecture" DO NOT USE FOR: simple applications - unnecessary complexity, microservices - use proper service boundaries, existing tightly coupled monoliths - requires significant refactoring
Records completed work progress to .trellis/workspace/ journal files after human testing and commit. Captures session summaries, commit hashes, and updates developer index files for future session context. Use when a coding session is complete, after the human has committed code, or to persist session knowledge for future AI sessions.
Identify and fix common testing mistakes across unit, integration, and E2E test suites. Use when tests are flaky, brittle, over-mocked, order-dependent, slow, poorly named, or providing false confidence. Use for "test smell", "fragile test", "flaky test", "over-mocking", "test anti-pattern", or "skipped tests". Do NOT use for writing new tests from scratch (use test-driven-development), refactoring architecture (use systematic-refactoring), or performance profiling without a specific test quality symptom.
User personas, customer journey maps, interview guides, usability testing, and card sorting. Use when building user understanding, mapping customer experiences, planning user research sessions, or defining Jobs-to-Be-Done.
Browser QA — Automated Visual Testing & Interaction
Guides idiomatic Lua 5.4 programming, module design, and project maintenance for Neovim plugin/config ecosystems (LazyVim, lazy.nvim) and macOS bar tools (SketchyBar/SbarLua). Covers style, tooling (StyLua, Selene, LuaLS), module patterns, and testing. Use when writing Lua code, configuring Neovim plugins, working with SketchyBar Lua configs, debugging Lua require/module errors, or when the user mentions Lua, .lua files, LazyVim, lazy.nvim, SbarLua, SketchyBar, luarocks, LuaLS, StyLua, or Selene.
When the user wants to build or improve a sales bot's ability to test individual message variants. Also use when the user mentions "message testing," "A/B testing messages," "variant testing," "message optimization," or "reply testing."
Use when setting up TYPO3 extension test infrastructure, writing unit/functional/E2E tests, configuring PHPUnit, mutation testing, mocking, CI/CD test pipelines, or debugging CI failures. Also triggers on: ensure proper testing, test matrix, integration testing, e2e testing, coverage, test generation.
