[bot] Missing instrumentation for Amazon Q Business Java SDK (qbusiness)

[braintrust-bot]

Summary

The Braintrust Java SDK instruments software.amazon.awssdk:bedrockruntime (direct model invocation via Converse/ConverseStream), but does not instrument software.amazon.awssdk:qbusiness — the official AWS SDK v2 module for Amazon Q Business, AWS's "fully managed, generative-AI powered enterprise chat assistant." This is a distinct AWS service and Maven artifact from all currently-instrumented Bedrock/OpenAI/Anthropic/GenAI modules, with its own conversational-agent execution surface.

What is missing

The software.amazon.awssdk:qbusiness SDK provides these execution-oriented surfaces, none of which are instrumented:

API	Client	Description
chat() / chatAsync()	QBusinessClient / QBusinessAsyncClient	Streaming, agentic conversation turn — retrieval-augmented generation over enterprise data sources, plugin/action invocation, attributed source citations
chatSync()	QBusinessClient / QBusinessAsyncClient	Non-streaming conversation turn (ChatSyncRequest/ChatSyncResponse)
putFeedback()	QBusinessClient	Feedback on a generated response (execution-adjacent, tied to a specific chat turn)

These are genuine model-execution/agent-run surfaces (not admin/CRUD) — Chat/ChatSync invoke Amazon Q's underlying generative model with retrieval, tool/plugin actions, and conversation state, analogous in kind to Bedrock's Converse/ConverseStream that this repo already instruments.

Why existing instrumentation does not cover this

• aws_bedrock_2_30_0 (instrumented) targets only BedrockRuntimeClientBuilder/BedrockRuntimeAsyncClientBuilder — a different client hierarchy and Maven artifact (bedrockruntime, not qbusiness).
• No other module references qbusiness or QBusiness classes.
• Amazon Q Business is a separate managed AWS product from Bedrock (own IAM actions, own API endpoint, own SDK artifact), so it is not reachable through any Bedrock instrumentation.

Braintrust docs status

• AWS Bedrock is listed as a supported cloud platform at https://www.braintrust.dev/docs/integrations/ai-providers, but Amazon Q Business is not mentioned anywhere in Braintrust's docs: not_found

Upstream sources

• API reference: https://docs.aws.amazon.com/amazonq/latest/api-reference/API_Chat.html and https://docs.aws.amazon.com/amazonq/latest/api-reference/API_ChatSync.html
• Java SDK client reference: https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/qbusiness/QBusinessClient.html
• Maven Central: software.amazon.awssdk:qbusiness — actively released alongside the rest of the AWS SDK for Java v2 suite

Local repo files inspected

• settings.gradle (lines 28–33) — lists all six instrumentation modules (openai_2_15_0, anthropic_2_2_0, genai_1_18_0, langchain_1_8_0, springai_1_0_0, aws_bedrock_2_30_0); no qbusiness module present
• braintrust-sdk/instrumentation/aws_bedrock_2_30_0/src/main/java/dev/braintrust/instrumentation/awsbedrock/v2_30_0/auto/AWSBedrockInstrumentationModule.java — instanceof checks limited to BedrockRuntimeClientBuilder/BedrockRuntimeAsyncClientBuilder
• Full-repo grep for qbusiness, QBusiness — zero matches
