## The read

The harness is commoditizing — compaction, skills, hosted deploy, and orchestration primitives are the new electricity. When every vendor ships a harness, the moat is how humans wire judgment, guardrails, and institutional context into the loop.

## What moved

- **Microsoft Agent Framework ships Agent Harness, CodeAct, and Handoff orchestration at BUILD 2026** — [Microsoft Agent Framework Blog](https://devblogs.microsoft.com/agent-framework/microsoft-agent-framework-at-build-2026-announce/)
  MAF (1.0 GA April 2026) adds Agent Harness via AsHarnessAgent() with automatic context compaction, filesystem memory, todo tracking, plan/execute modes, AgentSkillsProvider, BackgroundAgentsProvider, shell execution (.NET), ToolApprovalAgent, and OpenTelemetry. Foundry Hosted Agents deploy local MAF agents as containers with scale-to-zero, per-session VM isolation, and persistent filesystem. CodeAct (alpha) runs multi-tool Python in Hyperlight micro-VMs, cutting benchmark latency 52% and tokens 64%. HandoffBuilder adds directed multi-agent routing with developer-defined topology and guardrails. **Builder angle:** One method turns a chat client into a production harness with compaction, skills, sub-agents, and hosted deployment — collapsing what teams typically stitch from separate OSS pieces.

- **NVIDIA releases NemoClaw orchestration blueprints and OpenShell secure agent runtime** — [NVIDIA Newsroom](https://nvidianews.nvidia.com/news/enterprise-software-leaders-build-ai-agents-with-nvidia)
  NVIDIA Agent Toolkit ships NemoClaw blueprints (available now) connecting popular harnesses for long-running agents, plus OpenShell early preview for policy/privacy controls and routing queries to local vs cloud models. Nemotron 3 Ultra (550B MoE) targets agent harnesses including LangChain Deep Agents, OpenHands, and OpenCode. CUDA-X libraries (cuDF, cuOpt, NeMo, PhysicsNeMo, CUDA-Q) are exposed as domain-specific agent skills. Microsoft partners on Windows security primitives plus OpenShell; Canonical and Red Hat integrate OpenShell into Ubuntu and Red Hat AI. **Builder angle:** NemoClaw plugs orchestration blueprints into existing harnesses while OpenShell adds a policy-controlled runtime layer for cross-platform agent deployment.

- **Amazon Agent-Ops multi-agent framework automates SOPs with 85–97% accuracy in production** — [Amazon Science](https://www.amazon.science/publications/agent-ops-a-multi-agent-orchestration-framework-for-end-to-end-sop-automation-in-e-commerce-operations)
  Agent-Ops orchestrates three agents for e-commerce SOP automation: SOP Groomer converts ambiguous docs into automation-ready specs, WebAgent hits 91.3% task completion via demonstration-based learning on dynamic web UIs, and Document Verification Agent validates invoices and certificates at 94.2% accuracy across languages. Deployed across seven SOP categories in three regions with 83% case-resolution time reduction, used by 100 account managers. **Builder angle:** Demonstrates a supervisor plus specialized-worker orchestration pattern with measurable production accuracy on incomplete SOPs and unpredictable UIs — not just lab demos.
