    My OpenAI contract has wrapped up, and I'm looking for my next role. For nearly two years, I've been building robust AI chats, MCP tools, AI UI integrations (MCP Apps), and more. I wrote some of the first Codex plugins: Their plugin evaluator, a comprehensive data visualization

    1/ At @ThisDotLabs, I built a Codex Plugin, called Build Web Data Visualization with DevEx Lead @coreyching from OpenAI. With this plugin, Codex uses image gen to design the app and then implements it really well. See the examples below. Claude can’t do this!🧵

    I'm very hopeful that this RxJS Agent Plugin I'm working on will finally: 1. Fix the crappy RxJS y'all have been writing that makes your coworkers hate RxJS 2. Delete unnecessary RxJS code (which is a lot of it, really) 3. Migrate code to Web Platform Observables and small

    I have this work (mostly) done. However, I'm going to leave it in a Draft PR for the time being. After a lot of thought, I really do think the symbols architecture is the correct move, and I've moved on to prioritizing a universal Agent Plugin for RxJS.  🧵

    Based on feedback, last night I started adding parallel "RxJS 7-like" APIs to the RxJS 9 beta. Revisiting the rx function: it takes an ObservableInput (observable, promise, iterable, stream) first, followed by pipeable functions.🧵

    How many more years will developers care about the minutia of code? It's interesting to think about what agentic coding is poised to potentially undo. Do we still need Frameworks? Libraries? Ergonomic APIs? I can see the argument for linters and formatters, but the rest?

    @threepointone I think Cloudflare OS is cool, but is there a definitive list of use cases to help get my gears spinning on it? (Sorry if this is a dumb question)
