Applied AI Engineer @ WorkOS. Full-stack open-source hacker and technical writer. I love building tools and sharing knowledge.

Now imagine defending against these since the attackers can train on traces from each attack, but defenders must use lower tier tooling

This is how things will be for the foreseeable future.
they've been non stop trying to attack our systems for the past 48 hours a side effect is everything is getting hardened but damn we basically need agents going 24/7 because that's what they have

My "Scout" Grok Bot researches the web with DeepSeek and Firecrawl Features: • Short answer first, cited sources under it • DeepSeek search and fetch, Firecrawl as the fallback • Quick, checked research, no noise • Other bots can ask it too Template: x.ai/bot/iQgQc2K-fktcrfvPYn2…

Our AIE workshop is up: Teach Your Agent to Prove It's Done. With @nicknisi I show how to build verification loops so coding agents check their own work. Clear goals, CLI health checks, browser snapshots, LLM judges. A failure drives the next fix. piped.video/q4WC4TowkBo

My bot makes phone calls now, and not just for me. My other bots can ask it to call someone, and it hands the transcript back to them. I read the plan first and say go. x.ai/bot/R2Ju5BAkmL8GyEe1mDY…

I have severe time blindness and can't use calendars, so I built Margin: a bot that watches my schedule every hour for conflicts, back-to-back pileups and no time to rest, and clears my afternoon when I ask. Template is public, copy it: x.ai/bot/GqStm_9by2_ffroZOIC…

Another AI Engineer conference in the books! Nick Nisi and I gave a one hour interactive workshop, Beyond Done, on agent verification at scale. Nick also gave an awesome talk on forcing a fruit fly’s neural network to review code smells with Jev. I gave a talk, Factories of Loving Grace, on how we can produce better narrative outcomes using AI with the right mindset, and why I’m building factories for the people I care about. I unlocked a new achievement of making someone tear up during my talk. Exhausted and need to catch up on sleep but glad we went. #AIE

New achievement unlocked. Just heard someone say my talk at #aie nearly made them cry. I can sympathize, because most of my talks nearly make me cry. I just do it before and after.

We told Claude to touch a file when it ran the tests. It touched the file and skipped the tests. @nicknisi and @zackproser on building agent loops that can’t lie to you. Watch the full AIE session here: piped.video/watch?v=AgBAOXVx…

If you're at @aiDotEngineer in NYC today, stop by my talk in Sutton at 2:30pm to find out if you're really smarter than a fruit fly. 🪰

Last week at init(), I shared the next chapter of WorkOS. We’re building infrastructure for a world where humans and agents work together, and anyone can build software. Three new products with live demos: 1) Airlock • Give agents access without giving them unlimited access. • Define your policies in natural language. Let agents work within them, block what’s off-limits, and escalate decisions that need a human. • No more choosing between approving every action and "dangerously skip permissions." 🤖 2) Atlas • Turn any idea into a secure internal app with your favorite coding agent. • Auth, permissions, data connectors, databases, AI gateway, and deployment built in. • A secure home for everything your team builds. 🌐 3) Passport • Single-sign on is super annoying, so we fixed it. • With WorkOS Passport, you're automatically signed in to all your apps. • Zero sign-on. Just open your Mac and get to work. We believe companies in this next era won’t simply use AI. They’ll be redesigned around intelligence. And the world will need new infrastructure to power this revolution. That’s the future we’re building for. Full keynote below:
