[bot] Strands Agents TypeScript SDK (`@strands-agents/sdk`) not instrumented — no tracing for agent invocation, tool execution, or model calls

[braintrust-bot]

Summary

AWS's Strands Agents SDK has an official TypeScript package (@strands-agents/sdk, v1.0.0-rc.5, released April 30, 2026) for building production AI agents with tool use and multi-agent orchestration. Braintrust documents a Strands Agent SDK integration, but the docs page covers Python only — there are no TypeScript/JavaScript setup instructions and this JavaScript SDK repository has zero Strands instrumentation. Users who run agents with @strands-agents/sdk in Node.js get no Braintrust spans.

What instrumentation is missing

The @strands-agents/sdk package exposes these execution surfaces, none of which are instrumented:

SDK Method	Description
agent.invoke(message)	Execute an agent (agentic loop: model reasons → tools called → results fed back → repeat)
agent.stream(prompt)	Async-iterator streaming variant of agent execution
Tool callbacks (via tool())	Per-tool execution during the agent loop
Model provider calls (via BedrockModel)	Underlying model invocations inside each loop iteration

Users instantiate and run agents as:

import { Agent, tool } from "@strands-agents/sdk";
import { z } from "zod";

const myTool = tool({
  name: "weather",
  description: "Get current weather",
  input: z.object({ location: z.string() }),
  callback: async ({ location }) => `Sunny in ${location}`,
});

const agent = new Agent({ tools: [myTool] });
const result = await agent.invoke("What's the weather in Seattle?");

No coverage in any instrumentation layer:

• No auto-instrumentation config in js/src/auto-instrumentations/configs/
• No wrapper function (e.g. wrapStrandsAgent())
• No channels or plugin in js/src/instrumentation/plugins/
• No e2e test scenarios for Strands
• Grep for strands (case-insensitive) across js/src/ — zero matches

Analogous instrumented frameworks in this repo: OpenAI Agents (openai-agents), Google ADK (google-adk), Claude Agent SDK (claude-agent-sdk), Mastra, OpenRouter Agent — all of which are agent-execution frameworks similar in scope to Strands.

Braintrust docs status

supported for Python — unclear for TypeScript. The Braintrust integrations page at https://www.braintrust.dev/docs/integrations lists "Strands Agent SDK" under Agent Frameworks and links to https://www.braintrust.dev/docs/integrations/agent-frameworks/strands-agent, but that page documents Python-only setup (auto-instrumentation via braintrust.auto_instrument() or setup_strands()). No JavaScript or TypeScript instructions exist.
