From 560b042c5a70670fa38d2af5c877a10c85e7eba3 Mon Sep 17 00:00:00 2001 From: Antonio Carlos Carvalho de Oliveira Date: Tue, 23 Dec 2025 18:48:41 +0000 Subject: [PATCH 01/20] feat: add ACP (Agent Client Protocol) support for OpenCode Implement ACP client for standardized communication with OpenCode agent. This provides a cleaner alternative to the custom JSON format parsing. New files: - src/main/acp/types.ts - ACP protocol type definitions - src/main/acp/acp-client.ts - JSON-RPC client for ACP agents - src/main/acp/acp-adapter.ts - Convert ACP events to ParsedEvent format - src/main/acp/index.ts - Module exports Tests: - src/__tests__/integration/acp-opencode.integration.test.ts - Connect and initialize with OpenCode ACP - Create new sessions - Send prompts and receive streaming updates - Adapter converts ACP events to Maestro's internal format Key features: - JSON-RPC 2.0 over stdio - Session management (new/load) - Streaming message chunks - Tool call support - Permission request handling - Terminal and file system methods All 8 ACP integration tests pass with OpenCode v1.0.190. --- .../acp-opencode.integration.test.ts | 217 ++++++++ src/main/acp/acp-adapter.ts | 193 +++++++ src/main/acp/acp-client.ts | 526 ++++++++++++++++++ src/main/acp/index.ts | 18 + src/main/acp/types.ts | 451 +++++++++++++++ 5 files changed, 1405 insertions(+) create mode 100644 src/__tests__/integration/acp-opencode.integration.test.ts create mode 100644 src/main/acp/acp-adapter.ts create mode 100644 src/main/acp/acp-client.ts create mode 100644 src/main/acp/index.ts create mode 100644 src/main/acp/types.ts diff --git a/src/__tests__/integration/acp-opencode.integration.test.ts b/src/__tests__/integration/acp-opencode.integration.test.ts new file mode 100644 index 000000000..e77f322a7 --- /dev/null +++ b/src/__tests__/integration/acp-opencode.integration.test.ts @@ -0,0 +1,217 @@ +/** + * ACP OpenCode Integration Tests + * + * Tests for ACP (Agent Client Protocol) communication with OpenCode. + * These tests verify that Maestro can communicate with OpenCode via ACP + * instead of the custom JSON format. + */ + +import { describe, it, expect, beforeAll, afterAll, vi } from 'vitest';

This is behind a feature flag because: 1. ACP is still experimental 2. Some features may behave differently 3. Users can choose their preferred interface OpenCode is the only agent with native ACP support (supportsACP: true).
