Development Claude Skills
8 676 development skills from 759 authors. They write and change code. Half of them fit into 1 830 tokens or less — that is what one costs your context window when the agent loads it. 1 213 ship runnable scripts rather than instructions alone. 42 of them cannot work without an MCP server, most often rube. We also found 1 172 copies of these same skills sitting in other people's repositories — counted once here, not 1 172 times.

Use when creating a feature, designing folder structure, adding repositories/services/view models, wiring dependency injection, or deciding which layer owns logic.
Use when calling callable functions (httpsCallable), passing data to server-side logic, handling function errors/timeouts, configuring regions, or testing with the Emulator Suite.
Use when setting up Data Connect, writing GraphQL queries/mutations, configuring generated SDKs, handling offline, or applying security rules.
Use when scaffolding a project, refactoring into layers, creating view models/repositories, configuring dependency injection, or implementing unidirectional data flow (MVVM).
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 Azure DevOps connector to a Power Apps code app. Use when querying work items, creating bugs, managing pipelines, or making ADO API calls.
Adds Excel Online (Business) connector to a Power Apps code app. Use when reading or writing Excel workbook data from OneDrive or SharePoint.
Adds OneDrive for Business connector to a Power Apps code app. Use when uploading, downloading, listing, or managing files in OneDrive.
Adds Microsoft Teams connector to a Power Apps code app. Use when sending Teams messages, posting to channels, or integrating with Teams chat.
Creates Power Apps code apps using React and Vite. Use when building code apps, scaffolding projects, or deploying to Power Platform.
Adds SharePoint Online connector to a Power Apps code app. Use when reading lists, managing documents, or integrating with SharePoint sites. Can also create new SharePoint lists.
> 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 code-apps plugin to the GitHub repository.
Use when adding a Power Platform connector to an Expo/React Native Power Apps mobile app and no dedicated mobile connector skill exists.
Use when adding an unspecified data source to an Expo/React Native Power Apps mobile app; routes to Dataverse, SharePoint, or another connector.
> 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 mcp-apps plugin to the GitHub repository.
Use when the user wants to seed Dataverse tables with realistic sample records so a freshly-scaffolded code app shows real-looking data on first launch. Generates contextually appropriate rows from each table's schema and inserts them in dependency order. Mirrors microsoft/power-platform-skills/power-pages/add-sample-data, adapted for mobile apps.
Use when the user wants to read or write SharePoint lists, manage documents in a SharePoint document library, or create a new SharePoint list from a Power Apps mobile app.
Use when the user has finished building a mobile app, started it with `npm run dev`, and wants the running app monitored for runtime errors AND silent failures (empty lists, blank screens, swallowed network errors) and fixed autonomously. Accepts a free-text symptom (e.g., `/debug-app "todos not appearing on home screen"`) to drive terminal-log diagnostics — injects temporary console.log statements at data-path boundaries, reads Metro terminal output, and cleans up logs after the root cause is fixed. Otherwise polls the Metro terminal every 5s, classifies errors using an 8-category table, fixes inline or routes to the right skill, verifies each fix from terminal output, and exits after 3 consecutive clean polls. Foreground loop — blocks the conversation while running. Run only after the app is loaded.
Use when the user wants to start a new Power Apps mobile app (Expo / React Native / TypeScript, targeting iOS and Android) from scratch.
Use to find or create a Power Platform connection ID or reference for an Expo/React Native Power Apps mobile app.
> 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 model-apps plugin to the GitHub repository.
Creates, updates, and deploys Power Apps generative pages for model-driven apps using React v17, TypeScript, and Fluent UI V9. Orchestrates specialist agents for planning, entity creation, and code generation. Use it when user asks to build, retrieve, or update a page in an existing Microsoft Power Apps model-driven app. Use it when user mentions "generative page", "page in a model-driven", or "genux". This skill stands alone and does not require /app-builder — but if the user wants a whole app built (tables, forms, views, sitemap) rather than pages for an app that already exists, use /app-builder instead.
Debug a failed Power Automate flow run. Use when a flow failed, has errors, or the user wants to troubleshoot a run.
> 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 power-automate plugin to the GitHub repository.
>- Activates and provisions a Power Pages website in a Power Platform environment via the Power Platform REST API. Use when the user wants to activate, provision, turn on, or enable a Power Pages website or portal.
>- Integrates Power Automate cloud flows into a Power Pages site. Lists available flows, suggests relevant ones based on intent, identifies scenarios and web roles, creates metadata files, and generates client-side code to call flows. Handles both new flow registration and adding already-registered flows to additional pages without re-creating metadata. Use when the user wants to add, connect, register, or link a Power Automate cloud flow to their site.
>- Creates, edits, and manages Power Pages Server Logic files — server-side JavaScript that requirements, fetching documentation, implementing code, configuring site settings, and deploying. Use when the user wants to add server-side code, create API endpoints, or move logic from the browser to the server in their Power Pages site.
>- Creates a new Power Pages code site (SPA) using React, Angular, Vue, or Astro. Guides through component planning, design, implementation, validation, and deployment. Use when the user wants to create, build, or scaffold a new Power Pages website or portal.
>- Creates and configures web roles for a Power Pages code site. Web roles control access and permissions for site users, including authenticated and anonymous roles. Use when the user wants to create, add, set up, or manage web roles for their site.
>- Integrates Power Pages Web API into a site's frontend code with proper permissions and setup, and deployment for Dataverse CRUD operations. Use when the user wants to add Web API calls, connect to Dataverse, or add data fetching to their frontend.
>- Analyzes the user's business problem and recommends the right backend integration approach — Web API, AI Web API (generative summaries / grounded search), Server Logic, Cloud Flows, or a combination — for a Power Pages site, then routes to the appropriate specialized skill. Use when the user wants to add backend integration, connect to data, add AI summaries, or needs help deciding which backend approach to use.
> 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 power-pages plugin to the GitHub repository.
>- Scans a Power Pages site project for security issues in source code and dependencies. Runs static analysis and dependency scanning, then surfaces findings by category (code patterns, vulnerable packages, secrets, license issues). Use when the user wants to review code for security problems, check for vulnerable packages, find hard-coded secrets, run a code scan, or asks "is my code safe?", "check my dependencies", "find security issues in my source" — even if they say "audit my code" without mentioning specific tools.
