OpenCode can already spawn background subagents, but I just opened a PR letting you send synchronous tasks to the background. But more interestingly, this video was recorded + edited by 𝚘𝚙𝚎𝚗𝚌𝚘𝚍𝚎 running 𝚘𝚙𝚎𝚗𝚌𝚘𝚍𝚎 with 𝚝𝚎𝚛𝚖𝚒𝚗𝚊𝚕-𝚌𝚘𝚗𝚝𝚛𝚘𝚕.

I had some fun with Effect | TypeScript for the AI Era today. I made some visual effects, if you will, written in Effect + React.

I packaged up a little Effect | TypeScript for the AI Era-based HTTP cassette recorder library we made for testing slow, expensive, & flaky LLM calls in OpenCode. Here's a demo.

I know many of you have been long awaiting this monumental upcoming OpenCode feature. I'm so happy to announce that: Yes, when you go bonk on the logo it will respond with delicacy and suppleness to the current theme.

Fifth 𝚘𝚙𝚎𝚗𝚌𝚘𝚍𝚎 PR 🤩 Except this one isn't a PR yet... allow me to explain in today's Open Source Pro Tip. 𝒪𝓅𝑒𝓃 𝒮𝑜𝓊𝓇𝒸𝑒 𝒫𝓇𝑜 𝒯𝒾𝓅 𝒩𝑜. 1 While it’s generally cool to open unsolicited PRs for small bugs and fixes, if you’re adding something more complex like a brand‑new feature, it’s standard etiquette to get buy‑in by first recording a short ASMR‑lite walkthrough video and attaching it to the ongoing linked list of retweets of all your past PRs wherein the creator of the library repeatedly calls themselves "dumb" over and over backwards through time.
