Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 79 566 files from 1 758 authors, of which 61 913 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Raise test coverage for the microsoft/microsoft-ui-reactor repo with non-vacuous tests, picking the right tier (headless unit / selftest / E2E). Activate when a contributor asks to "improve test coverage", "add tests for X", "raise coverage", "cover the uncovered lines", "write selftests / e2e for this", "close coverage gaps", or "add unit tests". Baselines with tools/coverage, classifies each gap by tier, writes narrowly-scoped tests whose assertions fail if the target code is deleted, mutation-checks the key oracles, and runs the pr-review multi-model cross-check on the final commit. Applies changes (adds tests); does NOT change product code to chase coverage.
Reactor commanding — actions that appear in multiple surfaces (menu + toolbar), need keyboard shortcuts, or need `CanExecute`. `Command`, `StandardCommand`, `UseCommand`, `CommandHost`. Use when wiring shared actions or shortcuts.
Reactor charts and data visualization — choosing a chart type (line, bar, area, donut, `TreeChart`, `ForceGraph`), the chart DSL, `LabelView` / `XTickLabelView` / `YTickLabelView` for icon-plus-text and rich labels, and the visualization-best-practices rules. Use when adding charts or designing visualizations.
Reactor navigation — `UseNavigation` hook, `NavigationHost` renderer, `NavigationView` sidebar, `TabView` tabs, route params, stack operations, page lifecycle, deep linking, transitions, caching. Use when building multi-page apps or wiring sidebar/tab navigation.
Pointer to the full Reactor API signatures index (`references/reactor.api.txt`). The 90% of DSL content — hooks, components, common factories, modifiers, theme tokens, gotchas, React-to-Reactor mapping — already lives in `reactor-getting-started`. Load this skill only when you need to verify a less-common signature against the alphabetized full index.
Windows 11 design rules for Reactor — theme tokens, High Contrast, typography (`Heading`/`SubHeading`/`Caption`), 4px grid, acrylic surfaces, accessibility, animation, and a code-review checklist. Use when authoring, reviewing, or fixing visual styling.
Driving a running Reactor app via `mur devtools` — screenshot, inspect visual tree, click/type/scroll, read hook state. Use when diagnosing visible bugs (layout, contrast) or verifying a UI change landed.
Reactor input — gestures (`OnPan`, `OnPinch`, `OnRotate`), pointer events, drag-and-drop (`OnDragStarting`), focus management (`UseElementFocus`, `UseFocus`, `UseFocusTrap`). Use when implementing direct manipulation or custom focus behavior.
Reactor forms and validation — `UseValidationContext`, built-in validators (`Validate.Required`, `Validate.Email`, `Validate.MinLength`, etc.), `FormField` helper, masked input via `MaskEngine`, `InputFormatter`. Use when building data-entry screens, validation flows, or controlled-input forms.
Reactor docking windows — `DockManager`, `DockSplit`/`DockTabGroup`/`Document`/`ToolWindow`, drag-to-float/redock, roles (`DocumentArea`/`ToolWindowStrip`), persistence. Use when building IDE-/Office-shaped layouts with dockable, tear-out tool windows and document wells. READ THIS BEFORE wiring `DockManager` — the content-vs-shape ownership model is the #1 thing people get wrong.
Reactor essentials in one place — React-to-Reactor mental model, minimal app shape, hooks, the most-used factories, the critical gotchas, and project setup. This is the only skill you need loaded for typical Reactor work; load topical skills (`reactor-async`, `reactor-design`, etc.) only when the task explicitly calls for them.
Reactor top-level windowing cookbook: WindowSpec, OpenWindow, draggable windows, borderless/tool windows, placement persistence, taskbar visibility, z-order, aspect ratio, SizeToContent, displays, taskbar integration, and picker HWND wiring.
Paste-ready single-file Reactor recipes indexed by intent — list with add/delete/toggle, sidebar navigation between pages, form with validation + submit gating, async fetch with loading/error/data states, themed Win11 card surface. Use a recipe instead of synthesizing from prose: copy, adjust, ship.
Turn ANY WinUI control — a vendor/third-party control, your own custom Control, or a Windows Community Toolkit one — into a first-class declarative Reactor element with the [GenerateReactorWrapper] source generator, zero hand-written wrapper code. Covers auto-inference (props, content, two-way pairs, panel/items children, events), the [Wrap*] annotation cheat-sheet, imperative-lifecycle controls, diagnostics, and when to fall back to a hand-written ControlDescriptor.
Web 视觉设计 SKILL。输入 PRD / 参考 URL / 截图 / 关键词（任意组合），先产出一份标准化 DESIGN.md 设计规范，用户确认后据此生成 UI/UX、视觉、动效、响应式全部达标的 web 代码。专攻 web 端：Landing Page、Portfolio、产品页、博客、个人站、SaaS 介绍页等。当用户说"帮我做个网站""设计一个页面""参考 XX 做一个""把这个截图/PRD 做成网页""做一个 landing page""出一份 design 规范"时触发。不用于后端、数据库、纯逻辑 bug 修复。
Adds Dataverse tables to a Power Apps code app with generated TypeScript models and services. Can also create new Dataverse tables. Use when connecting to Dataverse, adding tables, creating schema, or querying Dataverse data.
Adds any Power Platform connector to a Power Apps code app. Generic fallback for connectors not covered by a specific skill.
Adds Azure DevOps connector to a Power Apps code app. Use when querying work items, creating bugs, managing pipelines, or making ADO API calls.
Configure the Canvas Authoring MCP server for the current coauthoring session. USE WHEN "configure MCP", "set up MCP server", "MCP not working", "connect Canvas Apps MCP", "canvas-authoring not available", "MCP not configured", "set up canvas apps".
Creates or edits a Power Apps Canvas App through the Canvas Authoring MCP coauthoring session. Handles new app generation from requirements, simple inline edits, and complex multi-screen changes with parallel screen builders. Triggers on requests to create, build, generate, modify, update, change, or edit a Canvas App or .pa.yaml files.
> Use this skill when the user wants to "report a bug", "file an issue", "report an issue", "submit a bug report", or report any problem with the canvas-apps plugin to the GitHub repository.
Adds a data source or connector to a Power Apps code app. Asks what the user wants to accomplish and routes to the appropriate specialized skill.
Guide the user to add a data source, connection, or API connector to a Canvas App via Power Apps Studio, then verify and continue. USE WHEN the user asks to add a data source, add a connection, add an API, add a connector, connect to SharePoint / Dataverse / SQL / Excel / OneDrive / Teams / Office 365, or any similar request to make new data available to the app. DO NOT USE WHEN the user is asking to list or describe existing data sources — call list_data_sources or list_apis directly instead.
