📋 Sumário


🔍 Visão Geral

Este servidor MCP atua como um Analista de Impacto Técnico, conectando-se à API GraphQL do GitHub para:

  1. Extrair contribuições (Commits, PRs, Reviews) de um usuário
  2. Analisar o conteúdo contra o framework Karpathy Skills
  3. Classificar o tipo e impacto arquitetural de cada contribuição
  4. Gerar relatórios executivos semanais com tradução técnico → negócio

🧠 Karpathy Skills Framework

O framework é baseado nas observações de Andrej Karpathy sobre pitfalls de engenharia de software, estruturado em 4 princípios:

1. Think Before Coding

"Don't assume. Don't hide confusion. Surface tradeoffs."

Mapeado para: Deep Understanding + Problem Solving

2. Simplicity First

"Minimum code that solves the problem. Nothing speculative."

Mapeado para: Technical Clarity

3. Surgical Changes

"Touch only what you must. Clean up only your own mess."

Mapeado para: Attention to Detail

4. Goal-Driven Execution

"Define success criteria. Loop until verified."

Mapeado para: Building from Scratch + Problem Solving
