From 4e6a03ba9350c31786e1d6ae7101c6c7558e6851 Mon Sep 17 00:00:00 2001 From: prajapatiy9826 Date: Thu, 28 May 2026 13:27:15 +0530 Subject: [PATCH] feat(nodejs): add Google ADK sample agent with Microsoft OpenTelemetry distro Adds a Node.js/TypeScript sample using Google ADK (Agent Development Kit) with Gemini models, integrated with Microsoft Agent 365 SDK for hosting, MCP tooling, notifications, and @microsoft/opentelemetry for observability. --- nodejs/google-adk/sample-agent/.env.example | 139 +++++++ nodejs/google-adk/sample-agent/.gitignore | 36 ++

Gemini LLM (with MCP tools) + → response → Teams +``` + +## 🔍 Core Components Deep Dive + +### 1. instrumentation.ts — OpenTelemetry Setup + +**Must be imported before all other modules** so the SDK can patch libraries (HTTP, Express). + +- Loads `.env` via `configDotenv()` before `@microsoft/opentelemetry` reads `A365_OBSERVABILITY_LOG_LEVEL` +- Configures `useMicrosoftOpenTelemetry()` with `AgenticTokenCacheInstance` token resolver +- Enables console exporters in dev mode for local debugging +- Patches `Agent365Exporter.postWithRetries` to log HTTP response bodies (like the Python distro) + +### 2. index.ts — Express Server + +- Loads auth config via `loadAuthConfigFromEnv()` — always, not just in production +- Registers health endpoints (`/`, `/api/health`, `/robots933456.txt`) **before** JWT middleware +- `authorizeJWT(authConfig)` protects all routes after health endpoints +- Routes `POST /api/messages` through `CloudAdapter.process()` → `AgentApplication.run()` + +### 3. hosting.ts — AgentApplication + Handlers + +**MyAgent** extends `AgentApplication` and configures: + +- `authorization: { agentic: { type: 'agentic' } }` — enables OBO token exchange +- `onActivity(ActivityTypes.Message, ...)` — message handling with baggage + typing loop +- `onAgentNotification("agents:*", ...)` — email, Word comment, lifecycle notifications +- `preloadObservabilityToken()` — refreshes exporter token via `AgenticTokenCacheInstance.refreshObservabilityToken()` +- `BaggageBuilderUtils.fromTurnContext()` — auto-populates tenant, agent, channel, conversation + +### 4. agent.ts — Google ADK Agent + +**GoogleADKAgent** implements the agent interface: + +- **Personalized instructions**: Injects user display name per turn +- **MCP tool initialization**: Delegates to `McpToolRegistrationService` with 10s timeout +- **Google ADK Runner**: `runner.runEphemeral()` with `InMemorySessionService` +- **InferenceScope**: Wraps invocations with `recordInputMessages`, `recordOutputMessages`, `recordFinishReasons` +- **Baggage**: `BaggageBuilderUtils.fromTurnContext()` for auto-populated observability context + +### 5. mcpToolRegistrationService.ts — MCP Tool Discovery + +- Exchanges OBO token with MCP platform scope (`ea9ffc3e-.../.default`) via `ToolingConfiguration` +- Calls A365 gateway directly (bypasses SDK's `listToolServers` which has a response parsing bug) +- Handles both response shapes: raw array and `{ mcpServers: [...] }` +- Creates `MCPToolset` with `type: "StreamableHTTPConnectionParams"` + `header` auth + +### 6. agentInterface.ts — Interface Contract + +```typescript +export interface AgentInterface { + invokeAgent(message, auth, authHandlerName, context): Promise; + invokeAgentWithScope(message, auth, authHandlerName, context): Promise; +} +``` + +## 🔧 Observability + +The sample uses the **Microsoft OpenTelemetry Distro** (`@microsoft/opentelemetry`) for end-to-end observability: + +- **Token resolver**: `AgenticTokenCacheInstance.getObservabilityToken()` — built-in singleton +- **Token refresh**: `AgenticTokenCacheInstance.refreshObservabilityToken()` on each turn +- **Baggage**: `BaggageBuilderUtils.fromTurnContext()` auto-populates all identity fields +- **InferenceScope**: Wraps LLM calls with input/output messages and finish reasons +- **A365 Exporter**: Sends spans to the A365 backend (flashpoint, sentinel, esp sinks) +- **Console exporters**: Enabled in dev mode for local debugging +- **A365_OBSERVABILITY_LOG_LEVEL**: Set to `info|warn|error` for exporter diagnostics + +## 🔐 Authentication + +| Mode | Config | Description | +|------|--------|-------------| +| **Teams/dev

Or for Vertex AI, set `GOOGLE_GENAI_USE_VERTEXAI=TRUE` and fill in `GOOGLE_CLOUD_PROJECT=` and `GOOGLE_CLOUD_LOCATION=`. +4. Press F5 to start debugging which launches your agent in Microsoft 365 Agents Playground using a web browser. Select `Debug in Microsoft 365 Agents Playground`. +5. You can send any message to get a response from the agent. + +**Congratulations!** You are running an agent that can now interact with users in Microsoft 365 Agents Playground. + +## Handling Agent Install and Uninstall + +When a user installs (hires) or uninstalls (removes) the agent, the A365 platform sends an `InstallationUpdate` activity — also referred to as the `agentInstanceCreated` event. The sample handles this in `hosting.ts`: + +| Action | Description | +|---|---| +| `add` | Agent was installed — send a welcome message | +| `remove` | Agent was uninstalled — send a farewell message | + +```typescript +if (context.activity.action === 'add') { + await context.sendActivity('Thank you for hiring me! Looking forward to assisting you in your professional journey!'); +} else if (context.activity.action === 'remove') { + await context.sendActivity('Thank you for your time, I enjoyed working with you.'); +} +``` + +To test with Agents Playground, use **Mock an Activity → Install application** to send a simulated `installationUpdate` activity. + +## Sending Multiple Messages in Teams + +Agent365 agents can send multiple discrete messages in response to a single user prompt in Teams. This is achieved by calling `sendActivity` multiple times within a single turn. + +> **Important**: Streaming responses are not supported for agentic identities in Teams. The SDK detects agentic identity and buffers the stream into a single message. Use `sendActivity` directly to send immediate, discrete messages to the user. + +The sample demonstrates this in `hosting.ts`: + +```typescript +// Message 1: immediate ack — reaches the user right away +await context.sendActivity('Got it — working on it…'); + +// ... LLM processing ... + +// Message 2: the LLM response +await context.sendActivity(response); +``` + +Each `sendActivity` call produces a separate Teams message. You can call it as many times as needed to send progress updates, partial results, or a final answer. + +### Typing Indicators + +The agent sends typing indicators in a loop every ~4 seconds to keep the `...` animation alive while the LLM processes the request: + +```typescript +let typingInterval: ReturnType | undefined; +const startTypingLoop = () => { + typingInterval = setInterval(() => { + context.sendActivity({ type: 'typing' } as Activity).catch(() => {}); + }, 4000); +}; +const stopTypingLoop = () => { clearInterval(typingInterval); }; +``` + +> **Note**: Typing indicators are only visible in 1:1 chats and small group chats — not in channels. + +## Running the Agent + +To set up and test this agent, refer to the [Configure Agent Testing](https://learn.microsoft.com/en-us/microsoft-agent-365/developer/testing?tabs=nodejs) guide for complete instructions. For a detailed explanation of the agent code and implementation, see the [Agent Code Walkthrough](Agent-Code-Walkthrough.md). + +For local Teams testing through a dev tunnel, keep the service connection values in `.env` populated. Bot Framework sends signed JWTs to `/api/messages` even in local development, so the server loads auth configuration from environment variables before accepting message activities. + +## Support + +For issues, questions, or feedback: + +- **Issues**: Please file issues in the [GitHub Issues](https://github.com/microsoft/Agent365-nodejs/issues) section +- **Documentation**: See the [Microsoft Agents 365 Developer documentation](https://learn.microsoft.com/en-us/microsoft-agent-365/developer/) +- **Security**: For security issues, please see [SECURITY.md](../../../SECURITY.md) + +## Contributing + +This project welcomes contributions and suggestions.
