Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@cuylabs/agent-foundry-agentserver-core

Shared host utilities for TypeScript Foundry Agent Server protocol packages.

This package mirrors the protocol-agnostic parts of Python azure-ai-agentserver-core: configuration resolution, request/session ID sanitization, request correlation IDs, server-version header formatting, standard error envelopes, common Express host middleware, readiness/liveness handlers, request logging, graceful shutdown helpers, and startup configuration logging. Protocol packages such as @cuylabs/agent-foundry-agentserver-invocations build their HTTP surface on top of these helpers.

Observability

Core always creates OpenTelemetry-compatible request spans and installs the Node async context manager so protocol handlers can read active baggage. It sets the Foundry baggage keys used by the Python host:

azure.ai.agentserver.invocation_id
azure.ai.agentserver.session_id
azure.ai.agentserver.response_id
azure.ai.agentserver.conversation_id
azure.ai.agentserver.streaming
azure.ai.agentserver.x-request-id

Exporter setup is optional and is driven by the same environment variables used by hosted agents:

| Variable | Behavior | | --- | --- | | APPLICATIONINSIGHTS_CONNECTION_STRING | Enables Azure Monitor export through the package's optional @azure/monitor-opentelemetry dependency | | OTEL_EXPORTER_OTLP_ENDPOINT | Enables OTLP HTTP trace export through the package's optional OpenTelemetry exporter dependencies |

Protocol packages call configureAgentServerObservability() by default. Apps that already own OpenTelemetry setup can disable package-managed exporter setup at the protocol layer and keep the span/baggage helpers.

Python Comparison

Compare this package to Python azure-ai-agentserver-core, not to a protocol package. Python exposes an AgentServerHost built on ASGI, Starlette, and Hypercorn. This TypeScript package exposes the equivalent protocol-agnostic host pieces for Express and Node HTTP, then protocol packages compose those pieces into their own server entry points.

@cuylabs/agent-foundry-agentserver-responses depends on this package in the same way Python azure-ai-agentserver-responses depends on azure-ai-agentserver-core. The local @cuylabs/agent-foundry-hosting package is different: it is agents-ts runtime glue, not a direct Python SDK peer.
