Works in AWS on Agentic AI and AWS DevOps Agent. Previously on CloudWatch, API Gateway, Lambda, IoT Core, DynamoDB
Agentic AI is the futuristic alien technology that I've been wishing we had over the last 20 years of building AWS. Now that it's here, there's some super cool stuff to build. www.cio.com/article/4187...
What 20 years of AWS taught me about agentic AI
AI agents are great at coding, but they tend to wander off-track unless you use explicit specs, solid design documents and strict testing to guide them.

Bumper bowling is a better sport for agents than regular bowling: blog.dyanacek.com/2026/05/31/a... (It's a metaphor for guardrails and feedback!)
Check out @quinnypig.com's conversation with me on "The Rise of Autonomous Ops: Inside AWS’s DevOps Agent" on @lastweekinaws.com! We talk #AWS history, #DevOps at @awscloud, and how we've encoded that into AWS DevOps Agent. All with Corey's quick wit. www.lastweekinaws.com/podcast/scre...

This Star Trek podcast is the funniest and most entertaining podcast I know. If you like Star Trek and frequent “juvenile” humor, check it out. They’re just starting their SECOND walk of EVERY episode in the ENTIRE franchise. I’ve been listening to this podcast for 10 years now.
On this week’s episode of #greatestgen, the last thing you want to encounter at Farpoint is tourists. Listen to the full episode at gagh.biz/greatestgen. #startrek #friendsofdesoto #fods #startrektng
📚📚📚 New blog and post: "Dune as an operational model", aka #DuneOps. 📚📚📚 The best fighters in the Dune universe are born from the harshest environments. That philosophy has fun parallels to #DevOps, #SRE, #PlatformEngineering, and Frontline #Ops. blog.dyanacek.com/2026/05/10/d...
Great UX for humans is still super important even in the age of frontier agents! This week, AWS DevOps Agent’s investigation view just got a nice “glow-up”, so check it out! A bunch of features launched a couple weeks ago along with going GA so take a tour here: aws.amazon.com/blogs/mt/ann...
Check out AWS DevOps Agent’s new Learned Skills features! The agent automatically generates skills about your system and learns from past investigations about using your tools. Skills were just one of the many recent features we added - check it all out here: aws.amazon.com/blogs/mt/ann...
Sure, AWS DevOps Agent just went GA, but we added a bunch of features at the same time, including Custom Skills, Learned Skills, Code Indexing - just to name a few! This video shows the new flexible On-Demand SRE Tasks in action. More in the blog! aws.amazon.com/blogs/mt/ann...
“Server ops is annoying,” said Yanacek, a trim man of 42 with a gray beard and jittery intensity. That is an accurate reflection of me that I had not considered before. The story talks about how #AWSDevOpsAgent is making ops less annoying! www.nytimes.com/2026/03/12/m...

In developer tooling, if a "rough edge" makes a tool hard to use, but a "sharp edge" makes a tool easy to accidentally misuse, then what kind of edge should a tool have?
It was super fun chatting with @kball.llc about spec-driven development and the future of coding. Since recording, Kiro announced new types of spec flows. Last week I used Kiro's new Bugfix Spec flow to one-shot a bugfix to production! Very thorough tests, clear implementation.
David Yanacek is a Senior Principal Engineer and a lead advisor on the Agentic AI team at @awscloud. he joins @kball.llc to discuss Kiro, Bedrock AgentCore, spec driven development, frontier agents, and the future of agentic software development. @dyanacek.bsky.social bit.ly/4kRGSCg

@kiro.dev just went GA, and with that, new features! My favorite is Property-based testing. PBT takes your Kiro spec to figure out behaviors want the system to have, and uses those to generate thorough tests. @devops.com.web.brid.gy devops.com/aws-extends-...

Come learn about @kiro.dev, a brand-new AI IDE that brings the fun of vibecoding into the scale of real-world production-scale projects. Recorded livestream here: www.youtube.com/watch?v=sXbI... And of course check out the blog: kiro.dev/blog/introdu...
A new way to vibecode from idea, to spec, code, docs, tests, and everything else to deploy to production. I've been using it for the last couple months and it has made it so that I can check things off the parts of my backlog that I never would have been able to get to! kiro.dev/blog/introdu...
Introducing Kiro
A new agentic IDE that works alongside you from prototype to production
kiro.dev
This is Kiro - the AI IDE that works on your messy, real-world projects. Other AI tools lose context when projects get complex. Kiro gives you spec-driven development that scales beyond prototypes. Preview: kiro.dev/blog/introducing-kiro/?trk=6b579e54-2920-4e24-a25b-d3c887a6ffdf&sc_channel=sm
Great article by Greg Nudelman on Agentic UX: www.uxforai.com/p/secrets-of... . It covers Amazon Q Developer's new operational investigations in Amazon CloudWatch, and talks about how humans and agents collaborate toward ruling in and out possible causes. #AI #Observability #Operations #UX

Apparently this year I started a tradition of wearing my slide art printed on my t-shirt. COP322 “Don’t get stuck: How connected telemetry keeps you moving forward”. The recording is now available: youtu.be/ad42UTjP7ds #AWSreInvent #Observability
Come learn cognitive techniques and tools for reducing time to resolution. We'll talk instrumentation, logs, telemetry correlation, and I'll show how Amazon Q Developer for troubleshooting operational incidents helps you move toward resolution even faster. Thursday 2pm! #AWSReInvent #observability
When I built demos for my #awsreinvent talk about troubleshooting, I was blown away at how quickly Amazon Q Developer was able to root cause the failures I was injecting. Come learn more for COP322 on Thursday 3pm. Try the new troubleshooting capability in CloudWatch: aws.amazon.com/blogs/aws/in...
