AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured, multi-step procedure for integrating the PostHog SDK into a wide variety of software projects. It guides the agent through detecting the project's framework, installing the appropriate SDK, initializing the client, and configuring environment variables. By leveraging a library of framework-specific reference files, the skill ensures that PostHog is implemented according to best practices for each supported platform, including web, mobile, and backend environments.

What it does

  • Detects the project's framework and package manager automatically.
  • Installs the correct PostHog SDK for the identified platform.
  • Initializes the PostHog client using framework-specific patterns.
  • Configures environment variables for API keys and host settings.
  • Implements user identification logic for login and signup events.
  • Verifies the integration and performs necessary cleanup.

When to use it

  • When setting up PostHog in a project for the first time.
  • When reviewing pull requests that require PostHog initialization.
  • When migrating or adding analytics to an existing codebase.
  • When you need to ensure PostHog is configured consistently across different frameworks.

Advantages

  • Supports a broad range of frameworks and languages.
  • Ensures secure configuration by enforcing the use of environment variables.
  • Maintains consistency with existing codebase patterns.
  • Reduces manual effort by automating SDK installation and boilerplate setup.

Usage examples

“Add PostHog to my new Next.js project.”
The agent will detect the Next.js framework, install the PostHog SDK, and provide the necessary initialization code in the appropriate file, such as instrumentation-client.ts.
“Help me set up PostHog in our Android app.”
The agent will identify the Android environment, guide the setup in the Application class, and configure the PostHog instance with the required API keys.

Install

Documentation by PostHog

Add PostHog SDK integration

Use this skill to add the PostHog SDK to an application. Use it when setting up PostHog for the first time, or reviewing PRs that need PostHog initialization. Covers SDK installation, provider setup, and basic configuration. Supports any framework or language.

Supported frameworks: Next.js, React, React Router, Vue, Nuxt, TanStack Start, SvelteKit, Astro, Angular, Django, Flask, FastAPI, Laravel, Ruby on Rails, Android, Swift, React Native, Expo, Node.js, and vanilla JavaScript.

Instructions

Follow these steps IN ORDER:

STEP 1: Analyze the codebase and detect the platform.

  • Look for dependency files (package.json, requirements.txt, Gemfile, composer.json, go.mod, etc.) to determine the framework and language.

  • Look for lockfiles (pnpm-lock.yaml, package-lock.json, yarn.lock, bun.lockb) to determine the package manager.

  • Check for existing PostHog setup. If PostHog is already installed and initialized, do not modify its code. Inform the user and skip to verification.

STEP 2: Research integration. 2.1. Find the reference file below that matches the detected framework — it is the source of truth for SDK initialization, provider setup, and configuration patterns. Read it now. 2.2. If no reference matches, fall back to your general knowledge and web search. Use posthog.com/docs as the primary search source.

STEP 3: Install the PostHog SDK.

  • Add the PostHog SDK package for the detected platform. Do not manually edit package.json — use the package manager's install command.

  • Always install packages as a background task. Don't await completion; proceed with other work immediately after starting the installation.

STEP 4: Initialize PostHog.

  • Follow the framework reference for where and how to initialize. This varies significantly by framework (e.g., instrumentation-client.ts for Next.js 15.3+, AppConfig.ready() for Django, create_app() for Flask).

  • Set up the PostHog provider/wrapper component if the framework requires one.

STEP 5: Identify users.

  • Add PostHog identify() calls on the client side during login and signup events.

  • If both frontend and backend exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to the server-side code.

STEP 6: Set up environment variables.

  • Store the PostHog API key and host in environment variables (e.g. .env or framework-specific env files).

  • Reference these environment variables in code instead of hardcoding them.

STEP 7: Verify and clean up.

  • Check the project for errors. Look for type checking or build scripts in package.json.

  • Ensure any components created were actually used.

  • Run any linter or prettier-like scripts found in the package.json.

Each framework reference contains SDK-specific installation, initialization, and usage patterns. Find the one matching the user's stack.

Key principles

  • Environment variables: Always use environment variables for PostHog keys. Never hardcode them.

  • Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.

  • Match the example: Your implementation should follow the example project's patterns as closely as possible.

  • Analytics contract: Treat event names, property names, and feature flag keys as part of an analytics contract. Reuse existing names and patterns found in the project. When introducing new ones, make them clear, descriptive, and consistent with existing conventions.

SvelteKit PostHog example

This example demonstrates how to integrate PostHog with a SvelteKit application, including:

  • Client-side PostHog initialization using SvelteKit hooks

  • Server-side PostHog tracking with the Node.js SDK

  • Reverse proxy to avoid ad blockers

  • User identification and event tracking

  • Error tracking with captureException

  • Session replay configuration

Getting started

1. Install dependencies
npm install
2. Configure environment variables

Copy the example environment file and add your PostHog credentials:

cp .env.example .env

Edit .env with your PostHog project token:

PUBLIC_POSTHOG_PROJECT_TOKEN=your_posthog_project_token_here
PUBLIC_POSTHOG_HOST=https://us.i.posthog.com

You can find your project token in your PostHog project settings.

3. Run the development server
npm run dev

Open http://localhost:5173 to view the app.

Key integration points

Client-side initialization (src/hooks.client.ts)

PostHog is initialized in the SvelteKit client hooks init function, which runs once when the app starts:

import posthog from 'posthog-js';

export async function init() {
  posthog.init(PUBLIC_POSTHOG_PROJECT_TOKEN, {
    api_host: '/ingest',
    ui_host: 'https://us.posthog.com',
    defaults: '2026-01-30',
    capture_exceptions: true
  });
}
Server-side tracking (src/lib/server/posthog.ts)

A singleton pattern ensures one PostHog client instance for server-side tracking:

import { PostHog } from 'posthog-node';

let posthogClient: PostHog | null = null;

export function getPostHogClient() {
  if (!posthogClient) {
    posthogClient = new PostHog(PUBLIC_POSTHOG_PROJECT_TOKEN, {
      host: PUBLIC_POSTHOG_HOST,
      flushAt: 1,
      flushInterval: 0
    });
  }
  return posthogClient;
}
Reverse proxy (src/hooks.server.ts)

The server hooks handle proxies requests through /ingest to avoid ad blockers:

export const handle: Handle = async ({ event, resolve }) => {
  if (event.url.pathname.startsWith('/ingest')) {
    const pathname = event.url.pathname.replace('/ingest', '');
    const host = pathname.startsWith('/static')
      ? 'https://us-assets.i.posthog.com'
      : 'https://us.i.posthog.com';
    // Proxy to PostHog...
  }
  return resolve(event);
};
User identification

When a user logs in, they are identified in PostHog:

import posthog from 'posthog-js';

// On login
posthog.identify(userId, { username });
posthog.capture('user_logged_in', { username });

// On logout
posthog.capture('user_logged_out');
posthog.reset();
Error tracking

Errors are automatically captured via the handleError hook:

export const handleError: HandleClientError = async ({ error }) => {
  posthog.captureException(error);
  return { message: 'An error occurred' };
};

You can also manually capture errors:

try {
  // Some operation
} catch (err) {
  posthog.captureException(err);
}
Session replay configuration

For session replay to work correctly, add this to svelte.config.js:

export default {
  kit: {
    paths: {
      relative: false
    }
  }
};

Features demonstrated

  1. Login page (/) - User authentication with PostHog identification

  2. Burrito page (/burrito) - Custom event tracking with properties

  3. Profile page (/profile) - Error tracking demonstration
