AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a structured workflow for integrating PostHog analytics into Ruby applications. It covers the full lifecycle of implementation, from initial setup and event planning to code modification and error tracking. The skill emphasizes best practices such as using environment variables for configuration, implementing instance-based client initialization, and ensuring proper resource cleanup using Ruby's ensure blocks to prevent event loss.
What it does
- Guides the setup of the posthog-ruby gem within a Ruby project.
- Provides a step-by-step workflow for planning and implementing event tracking.
- Demonstrates how to identify users during authentication flows.
- Includes patterns for capturing exceptions and tracking critical business events.
- Ensures robust resource management by requiring client shutdown in ensure blocks.
- Provides reference examples for CLI and script-based Ruby applications.
When to use it
- When you need to add product analytics to a Ruby-based application.
- When implementing server-side event tracking for critical business operations.
- When you need to track user actions or errors in non-web Ruby scripts or CLIs.
- When you want to follow standardized patterns for PostHog integration in Ruby.
Advantages
- Promotes consistent event tracking patterns across the codebase.
- Reduces the risk of data loss by enforcing proper client shutdown procedures.
- Prevents hardcoding of sensitive API keys through environment variable usage.
- Provides clear separation between event tracking and core application logic.
Usage examples
- “How do I initialize the PostHog client in my Ruby script?”
- The agent will provide the PostHog::Client.new initialization pattern, including the use of environment variables for the API key and host, and the requirement to call client.shutdown.
- “What is the correct way to track a user action in Ruby?”
- The agent will demonstrate the use of the client.capture method, specifying the required distinct_id, event name, and properties hash.

The example project shows the target implementation pattern. Consult the documentation for API details.
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.
Framework guidelines
posthog-ruby is the Ruby SDK gem name (add
gem 'posthog-ruby'to Gemfile) but require it withrequire 'posthog'(NOTrequire 'posthog-ruby')Use PostHog::Client.new(api_key: key, host: host) for instance-based initialization in scripts and CLIs
In CLIs and scripts: MUST call client.shutdown before exit or all events are lost
Use begin/rescue/ensure with shutdown in the ensure block for proper cleanup
capture and identify take a single hash argument: client.capture(distinct_id: 'user_123', event: 'my_event', properties: { key: 'value' })
capture_exception takes POSITIONAL args (not keyword): client.capture_exception(exception, distinct_id, additional_properties) — do NOT use
distinct_id:keyword syntax
Identifying users
Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.
Error tracking
Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.

title: PostHog Setup - Edit description: Implement PostHog event tracking in the identified files, following best practices and the example project
For each of the files and events noted in .posthog-events.json, make edits to capture events using PostHog. Make sure to set up any helper files needed. Carefully examine the included example project code: your implementation should match it as closely as possible. Do not spawn subagents.
Use environment variables for PostHog keys. Do not hardcode PostHog keys.
If a file already has existing integration code for other tools or services, don't overwrite or remove that code. Place PostHog code below it.
For each event, add useful properties, and use your access to the PostHog source code to ensure correctness. You also have access to documentation about creating new events with PostHog. Consider this documentation carefully and follow it closely before adding events. Your integration should be based on documented best practices. Carefully consider how the user project's framework version may impact the correct PostHog integration approach.
Remember that you can find the source code for any dependency in the node_modules directory. This may be necessary to properly populate property names. There are also example project code files available via the PostHog MCP; use these for reference.
Where possible, add calls for PostHog's identify() function on the client side upon events like logins and signups. Use the contents of login and signup forms to identify users on submit. If there is server-side code, pass the client-side session and distinct ID to the server-side code to identify the user. On the server side, make sure events have a matching distinct ID where relevant.
It's essential to do this in both client code and server code, so that user behavior from both domains is easy to correlate.
You should also add PostHog exception capture error tracking to these files where relevant.
Remember: Do not alter the fundamental architecture of existing files. Make your additions minimal and targeted.
Remember the documentation and example project resources you were provided at the beginning. Read them now.
Status
