## PostHog Instrumentation Skill

Help users add PostHog analytics, event tracking, and feature flags to their code.

## When to Use

* User asks to "add PostHog" or "add analytics"

* User wants to track events or user actions

* User needs to implement feature flags

* User asks about instrumenting their code

## Workflow

* Identify the framework (React, Next.js, Python, Node.js, etc.)

* Check for existing PostHog setup

* Add appropriate instrumentation

## Code Patterns

### JavaScript/TypeScript

```
`// Event tracking
posthog.capture('button_clicked', { button_name: 'signup' })

// Feature flags
if (posthog.isFeatureEnabled('new-feature')) {
// Show new feature
}

// User identification
posthog.identify(userId, { email: user.email })
`
```

### Python

```
`from posthog import Posthog
posthog = Posthog(api_key='<ph_project_api_key>')

# Event tracking
posthog.capture(distinct_id='user_123', event='purchase_completed')

# Feature flags
if posthog.feature_enabled('new-feature', 'user_123'):
# Show new feature
`
```

### React

```
`import { usePostHog } from 'posthog-js/react'

function MyComponent() {
const posthog = usePostHog()

const handleClick = () => {
posthog.capture('button_clicked')
}
}
`
```

## Best Practices

* Use consistent event naming (snake_case recommended)

* Include relevant properties with events

* Identify users early in their session

* Use feature flags for gradual rollouts

Use it when the user wants a summary of everything broken , not a deep-dive on one sync. The deep-dive on individual failures is diagnosing-failed-warehouse-syncs ; this skill is the scan that tells them where to look first.
