kungfu vs agent-bridge

kungfu: Kungfu keeps a unit of Work outside any single agent session, recording its objective, progress, evidence, next action and completion state, so the same Work can move between Codex, Claude, OpenCode, Amp or your own agent without re-explaining context. Each Agent attempt is recorded under the Work, a second live writer is blocked, and an Agent cannot approve its own result: completion goes through independent review. It is in Alpha.; 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.
