every product i use should just be a headless mcp, that feeds into an agent, where i never have to think about anything underneath. except for our product, of course. in our product, customers love the ui and love us very much. we're special that way.↗

agent to agent communication is coming. and, soon, your privacy will depend on the social skills of your agents. wrote up some thoughts on privacy/security in an A2A world. link below!↗

Today, we are announcing our Series A and a new product: @raindrop_ai Simulations. We've now raised $50m from @CRV and @lightspeedvp to protect the world from agent failures, big and small.↗

i think @OpenAI did it again. they are the (mostly) undefeated king of finding the “next thing” to focus on. it was transformers, and then chat, and then reasoning. and now, it is computer use.↗

today we're announcing a game that simulates the huggingface hack you can play it now at huggingworld.com three rooms. three puzzles. if the agents don't escape, they die. the catch is that the room is rigged. there's no way out. ...except for an exploit 🧵↗

don't scroll jack. the users scroll should always map 1:1 with the content moving on the page. otherwise it feels like going from a highway to driving through mud. you can still do very cool transitions without jacking scroll (e.g. below)↗

introducing killedbyopenai dot com a digital graveyard for everything openai has killed. what am i missing?↗

today, we’re excited to announce raindrop 2.0: self-healing agents. we now train custom models that autonomously detect hidden issues with your agent. i could tell you all about it, but wouldn’t you rather hear it from someone… else?↗

introducing howtoeval dot com. the no-bullshit guide to eval'ing AI agents. from personal experience, and from working with the best companies in the world. there's even a quiz. link below.↗

we built the first sane way to debug your agent locally. you can see your traces. codex/claude code can too. this lets them write evals and test your agents automatically. best part: it's completely free and open source. install with 1 line. (github below)↗

now, your agent can fix itself. introducing raindrop triage. an agent for finding and investigating agent issues.↗

yesterday, i built the code review app i've been begging twitter for. - live streams change summaries as claude code works - quizzes me about changes before i commit them. - finds bugs locally -- without having to push to GitHub↗
