PostHog Analytics Skill

Query and manage PostHog product analytics for Mediar applications.

Configuration

Host: https://eu.i.posthog.com Project Key (SDK): phc_NFSaZUao49XckpqaeyB3lIEKrFXhhXbKaI81jqZ8yn9

Personal API Key: Required for API operations. Read POSTHOG_API_KEY from .env.local

Getting a Personal API Key

  1. Go to https://eu.posthog.com/settings/user-api-keys
  2. Click "Create personal API key"
  3. Name it (e.g., "claude-code")
  4. Select scopes: insight:read, insight:write, dashboard:read, dashboard:write, query:read
  5. Add to .env.local: POSTHOG_API_KEY=phx_xxx...

PowerShell Queries (Windows)

Use PowerShell for all queries to avoid bash escaping issues.

Useful Filters

Event Properties

  • $pageview - Page view event
  • $autocapture - Auto-captured clicks
  • $referrer - Referring URL
  • $pathname - Page path
  • $current_url - Full URL
  • $browser - Browser name
  • $os - Operating system
  • $device_type - desktop/mobile/tablet

Filter Operators

  • exact - Exact match
  • icontains - Case-insensitive contains
  • regex - Regular expression
  • is_set - Property exists
  • is_not_set - Property doesn't exist
  • gt, lt, gte, lte - Comparisons

Insight Types

  • TRENDS - Time series charts
  • FUNNELS - Conversion funnels
  • RETENTION - User retention
  • PATHS - User journey paths
  • STICKINESS - Feature stickiness
  • LIFECYCLE - User lifecycle

Rate Limits

  • Analytics endpoints: 240/min, 1200/hour
  • Query endpoint: 2400/hour

AI Crawler User Agents (for server-side tracking)

These crawlers won't show in PostHog (JS-based), but you can track them server-side:

GPTBot, ChatGPT-User, ClaudeBot, Claude-Web, PerplexityBot,
Google-Extended, Applebot-Extended, CCBot, anthropic-ai

To track these, add server-side events in Next.js middleware or API routes.

Important Notes

  1. API Key required: Personal API key needed (not the public project key)
  2. EU Region: Mediar uses eu.i.posthog.com (not app.posthog.com)
  3. Project ID: Get from /api/projects/ endpoint first
  4. HogQL: Use for complex queries not supported by filters
  5. AI traffic: Client-side PostHog tracks referrals, not crawler bots
  6. Rate limits: 240 requests/min for analytics endpoints
