Since I joined Cognition I've been obsessed with learning how our eng team uses Devin themselves If we are building the best coding agent + we have the most cracked engineers + we've been fully AI-pilled from day one... it stands to reason that there is a lot to learn by just watching our technical staff work And yes there are a lot of tips & tricks. I recorded a video talking about my favorite... Agent Fan Out - asking your agent to break down the problem, spin up 10 more agents in parallel, and combine their results This is something I've seen everyone do - from our model research team spinning up 100 Devins to examine eval logs - or our product team using 5 child Devins to try out 5 different alternative implementations of the same thing If engineering is cheap and easy, why not build the product 10 times and choose the best one? Think of it in a master/slave context: Master Devin -> 10 Slave Devins -> Master Devin pulls their results There are two reasons this is useful 1. Agents are smartest when their context is small and their task is small & precise. Context windows are finite and too much becomes distracting 2. Agents are good at helping you break a large problem into independent & parallelizable chunks of work Every Devin is its own VM/computer so this also is just a great way to move faster. I've done a migration from React Native to Swift by having Devin break it up into 6 pieces then spin up new Devins to work in parallel In the video I build a greenfield project and try my best to show off this agent fan out concept. I also threw in a few other tricks that I've seen my coworkers do: - Let Devin write its own prompts (especially for creating child Devins). It's way better than us humans - Do tons of things at once. You should be absolutely frying your attention span. Your job should just be babysitting 38 different Devins - Don't be a blocker. Before letting the agent work I make sure to tell it to ask me any questions that would fill in ambiguities. Give your agent all the information it needs (and then some more) so that it can just cook without stopping to ask you questions every few minutes - Let Devin test itself. Integration sanity tests are pretty much solved Hope this is useful!!

Incredible last few minutes of the Rick Rubin / Adam Neumann interview. I got chills listening to this. --- Adam: We'll connected to this week's portion. We all have something that we're slaves to. We all have an addiction to anger, to ego, to power, whatever it is, idol worship that we have. We all have an Egypt. We all need to leave that Egypt, come out of it. When we come out of that Egypt, we all face a Red Sea. When we see that Red Sea, we all need to have the courage to walk into it so far that we drown. Only when we're willing to drown will the Red Sea be split and we'll go to our next level. We then go to our next level. We see the Red Sea split. Suddenly we're like, oh, everything is okay. And we forget. The moment we forget, we step into the desert. We all have to walk through our version of desert. That desert is between us, us, and God. No one else. The only decision we get to have is how long we're going to journey through that desert. Are we going to journey for 14 days like the children of Israel were supposed to? Or are we going to journey for 40 years because we're not learning our lesson? Our choice is not, are we going to get into the desert or not? It's how long will we be in. And once we go out of that desert, we all have our version of the promised land. And if we have the courage to look inside, see our own correction, our own limitation, look at it clearly now and say, I see you, and I'm going to get over it. I'm going to learn. I'm going to grow. I'm going to understand that life is not about falling down. It's about how I'm going to get up. I'm going to fall 1,000 times so I can get up 1,001 times. And in that last time when I get up and I'm actually ready to go to my next level, I'm going to wish for you, for me, and for everybody who are listening — please, may we have the courage to go to our next level because we know that the promised land is waiting right after it. And may we not be afraid when the whole world is saying this or that about us. Who cares? It's about what you think, what your wife thinks, what your kids think, and what the universe thinks. Rick: Amen. Adam: Amen. Thank you. Thank you, Hashem. Thank you.

How do you stand out in the age of agents? Now that every website has cool animations. Now that every meal is a bowl. ==the antidote is soul== The best meals are made with love. The best garmentos obsess over button details. Good Design is taste. It conveys a message. It’s human. We’ve redesigned and we’re really proud of the result. It’s inspired by my favorite restaurant in SF. Every icon is hand drawn.

My talk from the AI Engineer Code Summit is out! 🚨 "How Claude Code Works" and what we can learn about frontier agent architectures. Coding agents are suddenly really really good, and I'm trying to understand why. In short: better models, simple loop design, and bash tools
