Most "AI email agent" demos quietly assume the agent answers everything. Point a model at the inbox, generate a reply, send it, repeat. That's a fine loop right up until the model hits a message it shouldn't touch — an angry customer, a legal question, a refund the agent has no authority to approve — and confidently fires off a reply anyway. The expensive failures in agent email aren't the threads the agent gets wrong. They're the threads the agent answers at all when it should have stepped back. So let's build the part that steps back. Not the classifier that decides a message is risky — that's triage , a separate problem. This is the handoff : once something flags a thread as "needs a human," how do you actually pull the whole conversation out of the agent's reach, park it where a person can find it, and make sure the agent keeps its hands off until that person clears it? I work on the Nylas CLI, so the terminal commands below are the exact ones I reach for when I wire up an escalation path. Every operation gets the two-angle tour: the raw curl call and the nylas command that does the same thing. What the handoff actually needs An Agent Account is, underneath, just a Nylas grant with a grant_id . That's the spine of everything here, and it's worth sitting with: there is nothing new to learn on the data plane. The same grant-scoped endpoints you already use — Messages, Threads, Folders, Drafts — work against this grant exactly the way they work against any Gmail or Microsoft grant you got through OAuth. So the escalation path isn't some special agent feature. It's three plain operations you already half-know: A place to put escalated threads. A custom folder — call it Needs human — that lives alongside the six system folders every Agent Account ships with ( inbox , sent , drafts , trash , junk , archive ). A way to move the whole thread there. Not one message — the thread . A reply is just the latest message in a conversation; a reviewer needs the full chain. A way

DoorDash RAG Architecture, AI Agent Mesh, & Open-Source Supply-Chain Scanner Today's Highlights This week, we explore advanced AI agent orchestration, a detailed production RAG architecture, and an open-source tool for supply-chain security auditing. These stories provide practical insights into deploying and managing AI frameworks in real-world workflows. How DoorDash Built an AI Shopping Assistant That Doesn’t Rely on the LLM Alone (InfoQ) Source: https://www.infoq.com/news/2026/07/doordash-ai-ask-assistant/?utm_campaign=infoq_content&utm_source=infoq&utm_medium=feed&utm_term=global This article from InfoQ delves into the intricate architecture behind DoorDash's "Ask DoorDash" AI-powered shopping assistant. Unlike many solutions that solely depend on large language models, DoorDash's approach integrates an LLM with a complex retrieval-augmented generation (RAG) system and a comprehensive intent classification pipeline. This multi-layered framework ensures accuracy and relevance, particularly for tasks like recommending specific items or answering detailed product queries within their extensive catalog. The system also employs sophisticated filtering and ranking mechanisms to refine results, moving beyond simple keyword matching to provide highly personalized and context-aware suggestions. The technical deep-dive covers how DoorDash engineered this system to handle the nuances of user intent and data retrieval efficiently in a production environment. Key aspects include leveraging structured and unstructured data sources, managing latency for real-time interactions, and implementing robust feedback loops for continuous improvement. The article offers valuable insights into building scalable, reliable AI assistants that can augment LLMs with proprietary data and business logic, providing a blueprint for enterprises looking to deploy similar advanced applied AI solutions. Comment: This provides a fantastic real-world case study for augmenting LLMs with custom RAG and

We all hear about "Not comparing yourself to others" and that "comparing yourself is the thief of joy". To be honest, I agree and it's strange that I am contradicting myself because I compare myself A LOT. The more I looked into it, the more I realized that we have a natural tendency to compare ourselves. It's a human thing to do. The issue is that we tend to be very excessive over comparing ourselves to others to the point where it takes a toll on us. For example, we are demotivated to see someone's success because we believe we can't reach the goal they are in. We all have jealousy. Big or small. Even where I am at right now, I am still jealous that many people I know that got into big tech companies like Microsoft. To get more context, I want to share a story with you. Story Time Back in the day, I remember it was the year of the ACT. For those who don't know: It's a Standardized test that is needed for the college admissions to determine if you are admitted to their program. I remember I got a national average of 21 as my composite score and I was proud of the score I got since it's the national average during that time. However, I remember the day where my friends talked about the ACT. The most common thing I heard was: "Oh I got a 30" "I got a 32" "Man I got a 35, it was sooo easy" Hearing that makes me feel not only bummed out, but felt left out. I was feeling that I wasn't smart enough to be in the group. What's worse is that they got accepted into colleges and programs that are well known. Then they start boasting about their accomplishments. I felt like I am the odd-one-out because of my scores and their accomplishments I could not match. Why am I Talking about this? Looking back and knowing where they are at now, I am proud of who I become today. It's not that they have fallen downhill (they are still successful), but the route they have taken that I definitely could not follow. For example, on GitHub, many people fill up their contribution graphs to the

Bit by bit, Windows 11 is healing.

Smartphones these days have incredible cameras that are capable of taking smooth, sharp video, but the microphones are often lacking, to say the least. A wireless lavalier microphone can dramatically improve the audio quality of your videos, whether you’re the only one talking, or if you’re getting audio from multiple people. The DJI Mic 3 […]

With residential proxies all the rage, CISA urges router users to be vigilant.

Of all the debates raging about the potential downsides of AI, there is one worry causing the most hand-wringing among AI enthusiasts in Silicon Valley — that the giant AI labs that sell proprietary models are somehow acting like Trojan horses.

Noise-canceling earbuds are great for flights and focusing, but they're not always ideal for outdoor workouts. The last-gen Shokz OpenRun Pro's open-ear design lets you enjoy music while staying aware of approaching cars, cyclists, and other potential hazards, and right now they're on sale for $109 ($50 off) at Amazon, Walmart, and B&H Photo. That […]

Try the new Siri AI and system-wide performance improvements.

Siri has been on the Apple Watch since day one, though I'm usually hard-pressed to find people who actually make good use of it. It's kind of just… been there - mostly as a way to set timers when my hands are full. But after playing around with the watchOS 27 developer beta, I get […]

iOS 27 escaped the developer world today with the launch of the first public beta. I've been testing the new operating system since early June, looking for quirks and seeing if it can live up to the hype Apple promised in the keynote. This year's iOS upgrades are what one might call a Snow Leopard […]
