Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/coreai-ds-fluentui-react/SKILL.md
Find and apply CoreAI design-system documentation. Use when choosing or reviewing @coreai-ds/react-components components, props, tokens, themes, templates, or UI patterns.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/css-styling/SKILL.md
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.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/features-variants/SKILL.md
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.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/icons/SKILL.md
Conventions for picking, sizing, and bundling Fluent icons. USE WHEN: adding or changing an icon in a `*.tsx` file, or picking an icon name.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/interpreting-html/SKILL.md
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.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/lint/SKILL.md
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.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/new-variant/SKILL.md
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.
GitHubSkillgithub/replica/starters/coreai/.agents/skills/react-components/SKILL.md
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.

GitHubSkillgithub/replica/starters/coreai/.agents/skills/state-management/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/context-templates/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/accessibility-audit/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/add-seed-data/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/agent-browser/SKILL.md
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.

GitHubSkillgithub/replica/starters/shared/.agents/skills/browser-canvas-validation/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/component-design-system-review/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/create-prototype/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/developer-handoff/SKILL.md
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.
GitHubSkillgithub/replica/starters/shared/.agents/skills/prepare-feedback-proposals/SKILL.md
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.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
