Pulling labs, repos, and the catch-up path…
Harnesses, graphs, loops, APIs you call this week — tagged with Ng’s application skills. Not a training desk. New here is the decoder. Starting a project this week? Catch up is the four-skill map — not more news.
No splash for Production. The lanes below still scan.
Cookbooks for building AI apps: context, harness, graphs, cloud.

Next.js App Router: a streaming AI app with the AI SDKBuild the chat UI and the route handler this week. Cloud lab for shipping an application, not wiring a network.

Deploy a Python ADK agent to Cloud Run this weekGCP lab: Vertex/ADK as an agent app on Cloud Run. Ship the product, not a TPU blog.

MCP client on Cloudflare WorkersPut the harness on the edge: Workers talking MCP. A lab you take this week, not a training run.

OpenAI Agents SDK in a Modal sandboxCloud lab: run the coding-agent harness in Modal, not on a training cluster. Wrap, eval, ship.

Harness
Effective harnesses for long-running agentsLoops, tools, permissions: the wrapper you ship around the model. Take this workshop before you write another agent from a model drop.

Harness, loops, graphs, MCP, permissions, evals as acceptance.
Harness
Managed agents: decouple the brain from the handsAnthropic’s engineering note on splitting the planner from the tools is the production version of a harness. Same idea whether you like Claude or not.

browser-use’s Mac harness is the app on the laptop in front of you: Accessibility, a computer-use loop, tool permissions.

Paper
RedEvoAgent: red-team the execution harness, not the promptProduct-shaped red teaming: agents attacking the loop you ship, not unsafe-text evals on a chatbot.

Paper
Persona vs execution: govern the hands, not the voicePersona-Execution Separation is the audit story for agents at work: a character in the window, a separate, logged loop that actually acts.
arXiv 2608.274272d agoEditorial
If your agent cannot checkpoint, it is a demo. This is the open-source default for state, retries, and human-in-the-loop.

A hosted harness, not a new model. The news is that “deep agent” is becoming a product category.

Anthropic’s production MCP path: admins provision connectors through the identity provider. This is how you ship tools at a customer, not a demo OAuth loop.

Clone-to-ship: RAG, eval harnesses, agent wrappers. Not train-a-model.

No /dev/kvm, so the agent shipped a GitHub ActionHarness permissions are the product: the agent shipped a CI sandbox because it lacked /dev/kvm.

Drew Breunig: model cost stopped papering over a weak harness. Context and routing are the job again.

Harness
How to design an agent harness: work inside the system of recordAgents share data and policy with humans in one continuously updated view, with an audit trail. Harness design, not a valuation hook.
