[bot] Missing instrumentation for Azure AI Foundry Agents Java SDK (azure-ai-agents-persistent)

[braintrust-bot]

Summary

The Braintrust Java SDK instruments the Azure OpenAI-adjacent surface only indirectly via unrelated modules and has an open gap issue for com.azure:azure-ai-openai (#68) and com.azure:azure-ai-inference (#118), but does not instrument — and no open issue tracks — com.azure:azure-ai-agents-persistent, Microsoft's official Java SDK for Azure AI Foundry Agent Service. This is a distinct Maven artifact and client hierarchy (PersistentAgentsClient) providing a stateful, server-side agent-run execution surface (threads, runs, tool calls) comparable in kind to OpenAI's Assistants/Responses agent-run APIs.

What is missing

The com.azure:azure-ai-agents-persistent SDK provides these execution-oriented surfaces, none of which are instrumented:

API	Class	Description
createAgent()	PersistentAgentsClient	Defines a server-hosted agent (model, instructions, tools)
createThread() / createMessage()	PersistentAgentsClient	Manages a persistent conversation thread that an agent run executes over
createRun() / createRunAsync() / streaming run updates	PersistentAgentsClient	Executes an agent run against a thread — the core "agent execution" surface, including tool-call submission (submitToolOutputsToRun) and run status polling/streaming
createThreadAndRun()	PersistentAgentsClient	Combined thread-creation-and-run execution

Why existing instrumentation does not cover this

• No existing module (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) references com.azure.ai.agents or PersistentAgentsClient.
• This SDK is unrelated to com.azure:azure-ai-openai (issue [BOT ISSUE] Missing instrumentation for Azure OpenAI Java SDK #68, direct chat/embeddings calls) and com.azure:azure-ai-inference (issue [bot] Missing instrumentation for Azure AI Inference Java SDK #118, model-catalog inference) — it targets Azure AI Foundry's separate stateful Agent Service (threads/runs), not a one-shot completion endpoint, so neither existing gap issue covers its run-execution semantics.

Braintrust docs status

• Azure AI Foundry is listed as a supported cloud platform at https://www.braintrust.dev/docs/integrations/ai-providers, but no mention of the Agents/persistent-agent Java SDK, threads, or runs exists anywhere in Braintrust's docs: not_found

Local repo files inspected

• settings.gradle (lines 28–33) — lists all instrumentation modules; no Azure Agents module present
• braintrust-sdk/instrumentation/ — contains 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 Azure directory
• Full-repo grep for azure.ai.agents, azure-ai-agents, PersistentAgent — zero matches
