kai vs agent-bridge

kai: Kai is a semantic infrastructure for code change that understands code meaning—functions, dependencies, behavior impact—not just line diffs. It powers precise CI, context-aware IDEs, and verifiable AI coding agents.; agent-bridge: AgentBridge uses a two-process architecture with a foreground MCP client (bridge.ts) and a persistent background daemon (daemon.ts). It enables bidirectional communication between Claude Code and Codex via a control WebSocket and proxy, with automatic reconnection and message loop prevention.
