Capturing Events with PostHog SDKs

posthog-hello-world

jeremylongshore/claude-code-plugins-plus-skills

This guide provides minimal working examples demonstrating the three core PostHog functionalities: event capture, user identification, and feature flag evaluation. It covers both server-side (Node.js, Python) and client-side (JavaScript) SDK usage, as well as direct API calls, making it perfect for initial integration setup, testing, and learning basic product analytics patterns.

Optimizing PostHog Performance and Data Collection

posthog-performance-tuning

jeremylongshore/claude-code-plugins-plus-skills

This comprehensive guide outlines advanced strategies for optimizing PostHog in production environments. Key techniques covered include implementing local feature flag evaluation to eliminate network latency, optimizing event batching for network efficiency, utilizing strategic event sampling, and writing efficient HogQL queries. Master these methods to dramatically improve data collection reliability and query speed.

PostHog Webhook and Event Analysis

posthog-webhooks-events

jeremylongshore/claude-code-plugins-plus-skills

This skill guides you through integrating PostHog's Customer Data Platform (CDP) features. It covers setting up webhooks to trigger real-time actions (e.g., syncing to CRM, sending notifications) when specific user events occur. Furthermore, it demonstrates how to query event data using the Events API and perform complex funnel analysis using HogQL, allowing for deep, custom insights into user behavior.

Prefect Flow Builder Guide

prefect-flow-builder

jeremylongshore/claude-code-plugins-plus-skills

Guides and automates Prefect Flow Builder tasks for data pipelines, offering best-practice patterns, production-ready code, configuration templates, and validation advice whenever you mention the tool or request pipeline help.

Pyspark Transformer Guide
