Develop A2A Communication for Adversarial Simulation

Enhance your LangGraph system to include A2A communication between a 'Red Team Attack Strategist' and a 'Blue Team Defense Architect'. The Attack Strategist should communicate a specific, identified threat vector and a proposed attack sequence. The Defense Architect, upon receiving this A2A message, must process it, identify critical vulnerabilities (using RAG for context), and then formulate an initial set of counter-measures. Log the A2A message exchange and the Defense Architect's immediate response.
