Using AI agents like Claude to design architecture can be problematic as they lack context and may produce generic solutions that don't fit a team's specific needs. To avoid this, it's essential to keep humans accountable for architectural decisions and use AI agents to implement designs, not create them, to ensure that the final product is tailored to the team's unique constraints.
