Design e Frontend

Canonical overlay for graphical UI and web frontend work that is redesign-heavy, frontend-polish-heavy, or UX-review-heavy. Use alongside the repo's implementation skill when visual direction, accessibility, interaction quality, responsive behavior, forms, navigation, or data presentation need stronger design discipline; use `ui-guidance` for routine UI changes.

Next.js App Router patterns including server components, route handlers, middleware, parallel routes, intercepting routes, streaming, and caching strategies. Use when the user is building with Next.js 13+/14+/15+, asking about the App Router, server components vs client components, route handlers, Next.js middleware, or Next.js caching and revalidation. Trigger on any mention of Next.js, App Route

Project-aware unit testing guide with mock patterns, TDD discipline, and best practices. Auto-detects test framework (Jest/Vitest) and provides appropriate examples. Use when: (1) writing or fixing unit tests, (2) user says "寫測試", "write test", "補測試", "add test", (3) user encounters mock patterns or test failures, (4) user asks how to test a composable, component, or store, (5) user says "mock imp

Use when the user asks about the Shariah compliance of an ETF (SPY, QQQ, VTI, sector ETFs, etc.) or asks for halal ETF alternatives. Screens all underlying holdings, returns overall compliant %, purification, and suggests halal ETF alternatives when the ETF fails.

Python type checking expertise using ty - the extremely fast type checker by Astral. Use when: (1) Adding type annotations to Python code, (2) Fixing type errors reported by ty, (3) Migrating from mypy/pyright to ty, (4) Configuring ty for projects, (5) Understanding advanced type patterns (generics, protocols, intersection types), (6) Setting up ty in editors (VS Code, Cursor, Neovim, PyCharm).

Use when writing libGDX Java/Kotlin code involving 3D rendering — ModelBatch, ModelInstance, Model loading (G3DJ/G3DB/OBJ), ModelBuilder procedural meshes, Environment and lighting (DirectionalLight/PointLight), PerspectiveCamera, Materials and Attributes (ColorAttribute/TextureAttribute/BlendingAttribute), AnimationController, or camera controllers (CameraInputController/FirstPersonCameraControll

Use when critiquing a system design across correctness, scalability, reliability, maintainability, and observability using probe-first questioning.

QA agent: executes Epic AC (Acceptance Criteria) verification against an AC ticket or Epic. Runs all AC steps, classifies each as PASS/FAIL/MANUAL_REQUIRED/UNCERTAIN, and presents observed vs expected as pure facts (no root-cause judgement). On FAIL, surfaces human disposition gate (spec issue vs implementation drift); on PASS, it may transition the AC ticket to Done only after verification artifa

Overlay for environment-sensitive diagnosis — service startup, install issues, platform integration, headless/container behavior, and runtime smoke checks. Portable across repos where build, install, or runtime behavior depends on the local platform.

Patterns for multi-agent systems including orchestrator, pipeline, consensus, delegation, supervisor, and swarm patterns. Use when the user is building multi-agent workflows, coordinating multiple AI agents, implementing agent delegation or supervision, or designing systems where agents collaborate on complex tasks.

Use when writing, reviewing, or hardening Go tests that rely on stretchr/testify — `assert`, `require`, `mock`, and `suite` — including table-driven tests, subtests, parallel tests, mocks versus hand-written fakes, error-wrap assertions, and flaky test triage with `-race` and `-count`.
