OpenClaw Launches ACP: Agent Client Protocol for Stateful IDE-to-Agent Sessions

OpenClaw launched ACP (Agent Client Protocol) for stateful IDE-to-agent sessions, but developers building ACP integrations have no way to test, replay, or debug sessions without running the full stack. The protocol is new and documentation is sparse, leaving builders to guess at message formats and state transitions. This tool provides a local ACP test harness with session recording, replay, protocol validation, and a visual inspector for debugging agent-to-client communication.
