Development

Scaffold a new Android app with SDLC and Play-safe defaults — Kotlin/Compose Gradle project with version catalog, convention plugins, module layout, a targetSdk that meets the Play mandate, R8 on release, and git-ignored signing so it passes the pre-flight checker from day one. Use when starting a new Android project.

Validated Google Play release — runs the pre-flight checks and clears the Play policy gates, builds a signed app bundle with a git-stamped versionCode, uploads to a track, and walks staged rollout (with halt/roll-forward). Use when releasing an Android app to Play.

Generate a GitHub Actions workflow for Android — JDK + Gradle caching, build, unit + instrumented tests, Android Lint, run the Android pre-flight checks, and (optionally) sign + upload a signed app bundle to a Play track. Use when setting up CI for an Android app.

Manage the project's layer vocabulary — list allowed layers with file counts, add new layers, or safely remove unused layers. Reads the shelf-index for usage data; writes CLAUDE.md atomically. No agent dispatch.

Configure SDLC team formation and SDLC method for this project. Asks the four-option SDLC method question (solo / single-team / programme / assured), then recommends and installs team plugins based on project type, language, tech stack, and support needs.

Generate a GitHub Actions workflow for SDLC validation. Use when setting up CI/CD for a new project.

Package source files into plugin directories using release-mapping.yaml. Use when preparing a plugin release.

Render module-scoped human-readable traceability for a single module — REQs, DESs, TESTs, code locations with anchor links, plus the module-dependency graph as a markdown edge-list.

Generate boilerplate `# implements:` annotation for a function based on the artefact ID, inserting it as the first line of the function body.

Drawer component for React by Emil Kowalski — bottom sheets, snap points, nested drawers, clean API

Add loading, empty, error, and success feedback states to StyleSeed components and pages with practical mobile-first rules.

Generate reusable UI patterns such as card sections, grids, lists, forms, and chart wrappers using StyleSeed Toss primitives.

Scaffold a new mobile-first page using StyleSeed Toss layout patterns, section rhythm, and existing shell components.

Converts Stitch designs into modular Vite and React components using system-level networking and AST-based validation.

Planificar una feature compleja antes de implementarla. Genera un PRP (Product Requirements Proposal) con objetivo, comportamiento esperado, modelo de datos, y fases de implementación. Activar SIEMPRE antes de bucle-agentico, cuando la tarea involucra múltiples archivos/fases coordinadas, o cuando el usuario dice: planea esto, dame un plan, quiero agregar algo grande, necesito un sistema de X, blueprint esto.

Expert skill for converting any codebase (React/HTML/Next.js) into a pixel-perfect, SEO-optimized, and dynamic WordPress theme.

React and Next.js frontend development standards for Retail-Agentic-Commerce. Use when creating or modifying UI pages, components, hooks, styling, tests, or Apps SDK widget browser behavior in src/ui or related frontend surfaces.

Use when creating or editing documentation pages in docs/content/guides/ - covers YAML frontmatter, page structure, framework-specific example embedding, writing style, and sidebar registration

Use when writing tests for the Walkontable rendering engine - has its own separate test pipeline, runner, and configuration distinct from main Handsontable E2E tests

Use when modifying the Walkontable rendering engine in src/3rdparty/walkontable/ - overlay system, viewport calculations, scroll handling, DOM management, or the TableView bridge between core Handsontable and Walkontable

Use when developing or modifying the @handsontable/vue3 wrapper package - Vue 3 SFC components, deep watchers, and provide/inject patterns for settings propagation

Use when writing Playwright visual regression tests or adding a demo route for one - covers the decision rule (what earns a capture, and that a visual spec is in addition to a Playwright assertion), the custom tablePage fixture, the screenshot workflow, reg-suit comparison, and the demo routes in examples/next/visual-tests/

Use when writing, fixing, or reviewing tests for any Handsontable change (unit, E2E, or wrapper), and whenever a test is red during feature work. Enforces that tests prove intended behavior — not just execute code, and never "green for the sake of green". Covers intent-first (write the test from the requirement, ideally before the code), deciding whether the code or the test is wrong when red (default: the code), the banned ways of faking green, write-the-failing-test-first, verify-with-a-rea...

Use when refactoring Handsontable code - applying SOLID principles, Law of Demeter, plugin extraction, performance optimization, code modernization, and API redesign with backward compatibility preservation
