### PostHog Swift Integration - Configure PostHog using environment variables for project tokens and hosts, ensuring they are set within the Xcode scheme settings. - Add SPM dependencies by creating unique PBXBuildFile, XCSwiftPackageProductDependency, and XCRemoteSwiftPackageReference objects. - Enable outgoing network connections in macOS App Sandbox settings and use headers to maintain user correlation across client sessions.

### PostHog Integration for Nuxt 3.6 - Follow the four-step setup workflow to initialize PostHog analytics within your Nuxt 3.0 to 3.6 application. - Use environment variables for all PostHog keys and maintain consistency by following the provided example project patterns. - Identify users during authentication events and use specific headers to correlate client-side sessions with backend requests.

### PostHog React Native Integration - Install posthog-react-native and react-native-svg, then wrap your app with PostHogProvider inside the NavigationContainer. - Use react-native-config to securely load POSTHOG_PROJECT_TOKEN and POSTHOG_HOST from environment variables at build time. - Identify users during login and signup, using custom headers to maintain session correlation between frontend and backend.

### PostHog Integration for React and Vite - Follow the four-step workflow to initialize, configure, and finalize PostHog analytics within your React application. - Use environment variables for API keys and implement analytics capture directly within event handlers rather than useEffect hooks. - Identify users during authentication and maintain session correlation by passing distinct IDs via headers in API requests.

### PostHog Integration for React Router v7 - Implement PostHog analytics using the declarative pattern by following the four-step setup workflow and referencing the example project. - Use environment variables for API keys and trigger analytics capture directly within event handlers rather than inside useEffect hooks. - Identify users during authentication and maintain session correlation by passing distinct IDs via headers for backend-integrated flows.

### PostHog PHP Feature Flags - Install the posthog/posthog-php SDK and initialize it once using PostHog::init() with environment variables for API keys. - Implement server-side flag checks to prevent UI flickering, defaulting to boolean flags unless multivariate logic is required. - Use PostHog MCP tools to manage flags directly and ensure all SDK methods utilize associative arrays for distinct IDs and properties.

### PostHog Integration for Nuxt 4 - Follow the four-step setup workflow to integrate PostHog analytics into your Nuxt 4 application. - Use environment variables for all PostHog keys and follow the provided example project patterns for implementation. - Identify users during authentication and use specific headers to maintain session correlation between frontend and backend.

### omnibus-instrument-error-tracking Overview - >- - Use this skill to add PostHog error tracking that captures and monitors exceptions in your application. Use it after implementing features o - Supported platforms: React, Next.js, Web (JavaScript), Node.js, Python, Ruby, Ruby on Rails, Go, Angular, Svelte, Nuxt, React Native, Flutte

### PostHog Integration for Next.js App Router - Initialize PostHog using instrumentation-client.ts and secure all API keys using environment variables. - Trigger analytics events directly within user action handlers rather than using useEffect hooks. - Identify users during authentication and maintain session correlation by passing distinct IDs via custom request headers.

### HogQL Query Development - Use properties.$name for event data and person.properties.$name for person attributes, utilizing bracket notation for special characters. - Include the {filters} placeholder in WHERE clauses to enable dynamic UI-based filtering and dashboard date range integration. - Optimize performance by using uniq() instead of count(distinct) and always include a timestamp-based filter to limit data scans.
