This repository is automatically kept up to date. Every week, an AI agent researches the latest Claude, Anthropic, MCP, and AI news โ then opens a PR with updates across all guides, skills, and templates. I review and merge it manually. You're always reading current information.
This repo runs on API credits โ every coffee keeps it alive and updated.
Perplexity + Anthropic APIs power the weekly research agent that keeps every guide current.
If this guide saved you time, a coffee goes a long way.
