accessibility-audit

Audits actual components and routes against applicable WCAG 2.2 A/AA criteria using consumer-owned design-system evidence and repository tools. Use when asked for an accessibility audit, a11y check, keyboard or focus review, contrast check, or screen-reader verification.

add-seed-data

Creates or updates believable deterministic raw fixture scenarios without breaking an existing prototype. Use when asked to add or change fixtures, seed data, sample data, scenarios, or cross-record relationships. Not for UI redesign, live-data infrastructure, or unrelated commands.

agent-browser

Use for explicit agent-browser CLI checks or a named browser capability neither the Copilot canvas nor configured Playwright MCP can supply. Ordinary rendered checks and browser selection belong to browser-canvas-validation.

browser-canvas-validation

Use the Copilot browser canvas first for rendered route checks, interaction tests, screenshots and visual, responsive or accessibility evidence. Use configured isolated Playwright MCP only when the canvas is unavailable for a required check.

component-design-system-review

Reviews existing UI components for design-system consistency, states, responsiveness and accessibility using consumer-owned context. Use when asked to review component quality, check design-system adherence or audit component consistency.

context-templates

Shared context template library for setup-skills. Read when discovering context documents or their ownership. This library supplies research inputs, not active product context or a separate authoring workflow.

coreai-ds-fluentui-react

Find and apply CoreAI design-system documentation. Use when choosing or reviewing @coreai-ds/react-components components, props, tokens, themes, templates, or UI patterns.

create-prototype

Builds new UI prototypes and makes targeted changes to existing prototypes using consumer-owned context. Use when asked to build a prototype, mock up a UI, or add, change, refine or recreate part of an existing prototype. Do not use for unrelated tasks, routine commands, Git lifecycle actions, acknowledgements or infrastructure work.

css-styling

CSS Modules conventions, design tokens, container queries, and CSS-vs-component boundaries. USE WHEN: editing any `*.css` / `*.module.css` file in this repo, or writing styles for a new component.

developer-handoff

Writes a lightweight Markdown concept handoff from existing decisions and evidence. Use when explicitly asked for a developer handoff, to transfer a prototype or concept to another team, or to prepare a brief for implementation. Not for ordinary prototype completion, building, reviewing or publishing.

features-variants

Definitive guide to the app-local prototype feature/variant system: configuration, `useFeature()`, URL params, and anti-patterns. USE WHEN: editing `app/features.json`, using `useFeature()` in routes, creating design alternatives, A/B comparisons, layout options, alternate versions, or switching between design proposals. Trigger keywords: feature, variant, version, option, alternate, prototype, design option, A/B, comparison, switch between, try a different, another way, layout option, explore, side by side.

icons

Conventions for picking, sizing, and bundling Fluent icons. USE WHEN: adding or changing an icon in a `*.tsx` file, or picking an icon name.

interpreting-html

Map rendered/pasted HTML class names back to source code (CSS Modules, Fluent UI, Griffel). USE WHEN: inspecting Playwright DOM output, debugging styles in the browser, or reverse-engineering pasted HTML.

lint

Type-check and lint the CoreAI app. USE WHEN: the user asks to "lint", "fix lint", "run the linters", "check types", or after making code changes that need verification.

new-variant

Create a new design variant or alternative for a page using the built-in feature/variant system. USE WHEN: a designer wants to try a different layout, create an "option B" or "version 2", compare designs side by side, add an A/B alternative, or explore an alternate version. Do NOT build a custom toggle solution.

prepare-feedback-proposals

Prepare reusable repository-guidance improvements from selected Hub feedback findings when the user requests proposals or solutions after a review. Present each solution before edits; apply only explicitly approved proposals. Environment changes and prototype fixes are out of scope.

product-design

Guides product-design decisions using the consuming repository's design-system, product, and repository context. Use when designing UI, choosing layout or navigation, handling states and forms, messaging, disclosure, onboarding, visualization, copy, delete, filter, or search interactions. Triggers on 'design guidance', 'how to design', 'UI pattern', 'product design', 'scenario pattern', 'confirmation dialog', 'delete flow', 'copy to clipboard', 'filter', and 'search'.

prototype-controls

Create and wire Replica prototype controls. Use when asked to add or change dropdowns, sliders, input fields, toggles or action buttons that configure variants, scenarios, visible UI, app state or data sources, even without canvas terminology. Covers declarations, typed bindings, defaults, conditions, resets and actions. Product UI form fields and filters alone belong to create-prototype.

react-components

CoreAI Sandbox component usage: import boundaries, published CoreAI documentation, and local adapter inspection. USE WHEN: editing any `*.tsx` file, picking a component, or writing component imports.

replica-pick-and-polish

Implements a captured Pick & polish batch from the Replica prototype canvas. Use for Fix all requests with verified checkout, branch, batchId and noteCount, including pending follow-ups.

replica-publish-prototype

Publishes a Replica prototype through its existing workflow and Hub Build. Use for prototype canvas publishing requests that include verified target JSON and a publishing mode.

responsive-audit

Audits UI layout, overflow and navigation across product-defined viewports using consumer context and browser tools. Use when asked to check responsiveness, test mobile layout or audit breakpoint behavior.

review-hub-feedback

Review Hub feedback for reusable design themes through discovery, independent judging and synthesis. No diagnosis or optimization.

routing

React Router v7 routing conventions for this SPA. USE WHEN: editing `app/routes.ts`, adding/removing a route, or changing navigation.

setup-skills

Configures shared sources and drafts context with independent writers. Plain/fresh setup offers installation of user-named packages and reuses built-in browser capabilities, adding browser tooling only for an evidenced required-check gap. Use for setup, source repair, writing context or refreshing drafts. Configure-only skips tooling and authoring; installations and activation require separate approval.

start-app

Start the CoreAI Sandbox dev server and open it using available browser tools. USE WHEN: the user asks you to "start the app", "run the dev server", "open the app", or "launch CoreAI Sandbox".

state-management

CoreAI Sandbox's TanStack Query + mock-JSON data layer. USE WHEN: editing data-fetching hooks (`app/hooks/use*.ts`), adding mock data in `app/data/`, or wiring a component to query state.

visual-design-review

Reviews page hierarchy, grouping, density, actions and state design using consumer-owned product and design-system guidance. Use when asked for a visual design review, page critique or whether a new page communicates its task clearly.

write-tests

Write meaningful Replica tests. Use when adding regression coverage, testing new behavior, or changing existing automated tests.
