Stratus SDK

Every TypeScript agent SDK I tried treated Azure OpenAI as a second-class citizen. Stratus flips that. It's built Azure-first and includes everything you'd expect: tools, subagents, handoffs, sessions, streaming, structured output with Zod, guardrails, hooks, tracing, and MCP client support. Plus Code Mode, which lets the model write code to orchestrate tools in a loop instead of one call per turn. If you're on Azure and tired of adapter tax, this is for you.
