Provides instructions for installing and using the `android` CLI. The `android` command-line tool is a critical tool for Android development and helps you create new Android projects, run Android apps on devices, manage and interact with Android virtual devices (including screenshots and UI inspection), manage Android SDK components, look up official Android documentation, and discover and install official Android skills.

Stream router for Chat, Video, Feeds, and Moderation. Use when the user wants to build a new app with Stream, scaffold a project, add Chat/Video/Feeds/Moderation to an existing app, integrate Stream, audit or migrate an integration, build for Swift/SwiftUI/UIKit/iOS/Xcode/Android/Kotlin/React Native/Expo/Flutter, query Stream data, list channels, list calls, show flagged messages, find users, run getstream CLI commands, install the Stream CLI, set up Stream, configure moderation, search Stream SDK documentation, or look up Stream React/iOS/Android/Node/Flutter/Unity SDK methods. Routes to the right sub-skill based on the task.

Use this skill whenever the user asks about WWDC sessions, Apple Developer videos, WWDC transcripts, session IDs, technologies announced at WWDC, or wants an agent to find, compare, cite, summarize, or navigate WWDC session content. Fetch current docs from wwdc.ai via llms.txt and page markdown. Maintained by Superwall.com: the quickest way to add in-app subscriptions and paywalls to your app.

When the user wants to write a social media post for LinkedIn, Twitter/X, Threads, Bluesky, Facebook, Instagram, TikTok, Pinterest, or YouTube. Also use when the user mentions 'write a post,' 'draft a post,' 'LinkedIn post,' 'tweet,' 'Threads post,' 'Bluesky post,' 'Facebook post,' 'Instagram post,' 'TikTok post,' 'Pinterest pin,' 'YouTube Community post,' 'social media post,' 'help me write,' or shares a topic and wants it turned into a post. For deeper visual-platform caption writing, see caption-writer-sms. For multi-part content, see thread-writer-sms. For carousels, see carousel-writer-sms. For opening lines, see hook-writer-sms.

MANDATORY ENTRY POINT for generating or writing tests. Invoke this skill before editing files whenever the user asks to generate tests, write/add unit tests, scaffold a test project or suite, improve/achieve coverage, extend an existing suite to cover an untested method, or test an app, API, service, module, library, or package. Applies to a single function, method or file as much as to a whole project — scope changes how much of the workflow runs, never whether the skill applies. Invoke it when the workspace looks sparse, gutted or partially deleted — then test only the source that remains and never restore missing source. Polyglot: C#/.NET, Python, TypeScript/JavaScript, Go, Rust, Java, Ruby. DO NOT USE FOR: running existing tests (use run-tests); analyzing coverage reports (use coverage-analysis or crap-score); MSTest-specific test authoring or modernization (use writing-mstest-tests).

Guide for organizing MSBuild infrastructure with Directory.Build.props, Directory.Build.targets, Directory.Packages.props, and Directory.Build.rsp. USE FOR: structuring multi-project repos, centralizing build settings, implementing NuGet Central Package Management (CPM) with ManagePackageVersionsCentrally, consolidating duplicated properties across .csproj files, setting up multi-level Directory.Build hierarchy with GetPathOfFileAbove, understanding evaluation order (Directory.Build.props → SDK .props → .csproj → SDK .targets → Directory.Build.targets). Critical pitfall: $(TargetFramework) conditions in .props silently fail for single-targeting projects — must use .targets. DO NOT USE FOR: non-MSBuild build systems, migrating legacy projects to SDK-style (use msbuild-modernization), single-project solutions with no shared settings.
