From 2e8d589dffc3c50ebacd16134e46d3184438ef5f Mon Sep 17 00:00:00 2001 From: CleverThis Date: Mon, 20 Apr 2026 06:59:20 +0000 Subject: [PATCH 1/8] feat(tui): TuiMaterializer A2A integration layer Implement TuiMaterializer class that integrates TUI output with the A2A (Agent-to-Agent) communication system, enabling structured output streaming and event-based communication between agents. - Add TuiMaterializer class implementing MaterializationStrategy protocol - Add TuiA2aIntegration class for converting TUI events to A2A events - Add TuiA2aAdapter class for bridging TUI output and A2A infrastructure - Add comprehensive Behave tests for all components - Support event buffering, serialization, and A2A response creation - Implement lazy imports to avoid circular dependencies ---
