🎯 Overview

Sistema progettato per automatizzare la creazione e l'aggiornamento della documentazione tecnica di sistemi infrastrutturali complessi (VMware, Kubernetes, Linux, Cisco, ecc.) utilizzando un Large Language Model locale (Qwen).

Caratteristiche Principali

• ✅ Raccolta dati asincrona da molteplici sistemi infrastrutturali
• ✅ Isolamento di sicurezza: LLM non accede mai ai sistemi live
• ✅ Change Detection: Documentazione generata solo su modifiche rilevate
• ✅ Redis Cache per storage dati e performance
• ✅ LLM locale on-premise (Qwen) tramite MCP Server
• ✅ Human-in-the-loop validation con workflow GitOps
• ✅ CI/CD automatizzato per pubblicazione

🏗️ Architettura

Il sistema è suddiviso in 3 flussi principali:

1. Raccolta Dati (Background): Connettori interrogano periodicamente i sistemi infrastrutturali tramite API e aggiornano Redis
2. Change Detection: Sistema di rilevamento modifiche che attiva la generazione documentazione solo quando necessario
3. Generazione e Pubblicazione (Triggered): LLM locale (Qwen) genera markdown leggendo da Redis, seguito da review umana e deploy automatico

Principio di Sicurezza: L'LLM non ha mai accesso diretto ai sistemi infrastrutturali. Tutti i dati sono letti da Redis.

Principio di Efficienza: La documentazione viene generata solo quando il sistema rileva modifiche nella configurazione infrastrutturale.
