This is nice because now I can pull in this power to validate templates only when I need to do that action which frees up my context window!

Having post #AWSreInvent blues, so I decided to reminisce about my visit to the AWS Certified Lounge. Generated this video using @grok Imagine. The opening image is a real photo I took, then had Grok generate the video from it. It looks remarkably like my desk when I'm studying for certs with all the notes I take! Here’s the prompt I used: Late night study session aftermath, MacBook Pro screen glowing with AWS Solutions Architect practice exam results, camera crane movement rising from keyboard level upward and backward, revealing scattered study materials, celebratory CERTIFIED AWESOME coffee cup still steaming, half-eaten victory brownie on plate, disposable coffee cup knocked over empty, purple-blue neon lighting from off-screen monitor creating dramatic rim light, exhausted but triumphant atmosphere, desk cluttered with handwritten flashcards and crumpled notes, golden hour window light mixing with cool LED glow, emotional payoff moment after months of preparation, shallow focus pulling from laptop screen to celebration spread, 8 seconds, documentary-style authenticity

@brooke_jamieson @AWSEvents Great work!

When I say that @AWSEvents wanted to make this the most developer focused #reInvent ever, this is what I mean! The merch store team asked me to help write the copy for these signs so they would resonate with developers, and it’s so cool finally getting time to see them irl!

Success! Now I can hold an AMA about the latest announcements here at the airport haha. Stop by gate D9 if you want to get up to speed 😂 First pass, Kiro implemented the AWS Knowledge MCP server for the agent, but I asked it to use the new AWS-MCP server. Kiro researched and implemented it. I also noticed the agent wasn’t always retrieving the most recent announcements. I asked Kiro to prioritize the latest ones; it updated the agent’s system prompt, and the agent started working perfectly. It even grouped them into re:Invent announcements and November ones. With just a couple of prompts to Kiro and a few minutes while waiting to board, I have a working agent that fetches the latest AWS announcements and summarizes each in a sentence or two. It actually took longer to take the pictures and write this post than to build the agent!! 👻

While we wait for the airplane to leave #AWSreInvent (😭), let’s see if we can fire up @kirodotdev and create an agent that will go find the latest AWS announcements to help me catch up on everything I missed this week! 👻

A great concise way to see the big announcements at #AWSreInvent 👇

Love seeing all the Kiro updates! #AWSreInvent

@DigitalColmer @Werner Woah! I must have missed something. Why is it his last RIV talk?

😍 So inspired by the legendary Werner Vogels...his last AWS reInvent talk...😢 Have pride in your work...🙏 This piece is owned by me, inspired by @Werner with a little Gen AI help...🙏 The Renaissance Developer in 2025: 1/6 - is curious 🤔 Doesn’t accept “it just works”; keeps pulling threads until the entire sweater unravels and they’re holding the original yarn. 2/6 - thinks in systems 🧠 Zooms out to see how the tiny cog they’re polishing actually moves the whole machine. 3/6 - communicates ✍️ Can explain a foundation model to a five-year-old, a Project Manager, an HR executive and a kernel dev without ever changing the core truth. 4/6 - is an owner 🔥 Treats a 3 a.m. prod alert like waking up to their own house on fire. No “not my code,” just “how do we put this out and make sure it never burns again.” 5/6 - is a polymath 🛠️ Expands their mind with industry, technical, soft skills etc...to become more T-shaped 6/6 From flying machines to Mona Lisa—da Vinci built the impossible to change the world. Let's build like da Vinci...🔥 #TheDigitalCoach #AWS #AWSreInvent

That’s a wrap for #AWSreInvent day 3! Ended the night at the AAI party and had a great time catching up with everyone. Had the pleasure of running into @DigitalColmer again! Took some selfies at the party but after reviewing them they were very blurry so enjoy this Wizard of Oz pic 😂

@maishsk @jameshoodcodes Wow that’s quick!!

#reinvent2025 session recordings are already starting to come online!!! @AWSEventsChannel/search?query=dev403" target="_blank" rel="nofollow noopener">youtube.com/@AWSEventsChan… Here is the Code Talk that @jameshoodcodes and I delivered on Monday What are some of your favorites so far from the event?

Learning how to migrate the well-architected way in our workshop this morning! #AWSreInvent

Love the analogy of Kiro powers being like Neo instantly downloaded martial arts expertise in The Matrix! #AWSreInvent

Had a great discussion in today’s workshop about agent memory in AI systems, and thought I’d share what makes short-term vs. long-term memory in AgentCore Memory different and when to use each. Short-term memory captures turn-by-turn interactions within a single session, letting agents maintain immediate context so users don’t repeat themselves. Think of it like working memory—when you ask “What’s the weather in Seattle?” and follow up with “What about tomorrow?”, the agent remembers you’re still talking about Seattle. Long-term memory automatically extracts and stores key insights across multiple sessions—things like user preferences, important facts, and session summaries. This is persistent knowledge that creates personalized experiences over time. For example, if you mention preferring window seats during a flight booking, that preference gets stored and the agent can proactively offer window seats in future conversations. This ties directly into context engineering—the practice of designing systems that provide the right information, in the right format, at the right time to help AI models accomplish tasks. While prompt engineering focuses on crafting individual instructions, context engineering is about building dynamic systems that manage information flow across multiple interactions. Memory systems are a core component of context engineering, determining what information gets included when the model generates responses. By combining short-term and long-term memory strategically, you’re engineering the context that makes AI agents feel less like stateless question-answerers and more like intelligent assistants that actually know you. #AWSreInvent

The second day of #AWSreInvent has been off to an exciting start. We started off with a workshop on Bedrock AgentCore. Next up is a workshop on generative AI security testing and protection strategies, where we’ll explore red teaming techniques to assess the security of AI stacks. Let’s go!

@SwamiSivasubram @kirodotdev Spooky!

Made it through the house of @kirodotdev at #AWSreInvent. This haunted house has all the developer spooks. Enter if you dare for some Kiro swag!

An amazing first day of #AWSreInvent comes to an end. Supported a couple workshops today and will be back at it again tomorrow. Was busy most of the day and trying to catch up with announcements. What are some of the ones that stood out to you?

The first of many selfies this week starting with the one and only @DigitalColmer #AWSreInvent

@edjgeek Looks fun!

What does a hackathon on a bus look like? #AWSreinvent #r2rhack
