Most agent frameworks put safety rules in the system prompt and hope the model follows them. Wrong layer — one injection and they're gone.

OpenShell enforces policy via a YAML file.

A supervisor sits outside the agent and controls:
🌐 network — default deny
📁 filesystem — sandboxed workspace
🧠 inference — managed endpoint
🔑 credentials — injected at runtime

Compromise the agent, the policies still hold.

[Sam Witteveen @Sam_Witteveen]

OpenShell is key for Agents - NemoClaw is a blueprint:

- Harness (swappable)
- Model (swappable)
- Runtime — always OpenShell

The runtime is the part doing the security work. Swap everything else, that stays. That's the piece worth understanding.

DeepAgents can be that harness!

NVIDIA released Nemotron 3 Nano Omni.

Open with a full paper of recipes for their data and SFT.

One Open model. Text, images, video, audio — all in one. Mamba-MoE backbone, Vision encoder, Parakeet audio encoder.

7 things every team needs locked down before shipping a multi-user agent to production.

Rogue agents can run up a $10K bill overnight. Agents can hallucinate for 100s of users. Most builders don't notice. Here's what you should be monitoring.

TL;DR 📋
🔀 Model control - unified layer between your code and models, swap providers without breaking your stack
📝 Prompt registry - version your prompts, keep them out of the codebase, treat them like a second tier of code
🛡️ Guardrails - pre and post LLM, pre and post tool calls. Handle PII, PHI, prompt injection, and output filtering
💰 Budget limiting - hard caps per model and project. The cloud providers won't do this for you
🔧 Tools & MCPs - central auth, granular permissions, test every one
📊 Monitoring & Tracing - trace every request, response, error, and latency spike
✅ Evals - before go-live and after. Catch the silent failures before your users do

LangChain's CEO refused to let employees install OpenClaw on company laptops — then called it one of the most important agent projects in years. The paradox explains everything about where enterprise AI is heading. https://t.co/9T36UkYGXD

It's true: the web is not built for AI agents. But that's changing. @Sam_Witteveen summarizes the emerging WebMCP toolset from @googlechrome, @Microsoft, et al.

Web browsing is expensive and inconsistently effective for agents. WebMCP changes that.

Anthropic launched Cowork last week.
One competing startup's response? Pivot their product and open-source EVERYTHING.

The tweet announcing it hit 1.7M views.

Here's the @Eigent_AI story 🧵

Apple going with fine tuning of Gemini (Flash? / Flash Lite?) is probably smarter for them than jumping in to a fully "make your own models" strategy at this point in the game.

🧵 Google just dropped UCP (Universal Commerce Protocol) at NRF with @sundarpichai himself announcing it 🛒
This is Google's play for agentic commerce - and it's built with Shopify, Etsy, Target, Walmart & Wayfair. Here's what you need to know 👇

Kimi K2 Thinking by @Kimi_Moonshot just dropped and it's very impressive. This model is now beating OpenAI, Anthropic, and Google on major benchmarks. The LLM landscape just shifted dramatically.
