Mitchell Hashimoto drops a masterclass on shipping real features with AI—no hype, just pragmatic vibing through a non-trivial Ghostty update. Meanwhile, Andreas Thomas walks us through why Unkey ditched serverless after two years of fighting latency demons (spoiler: 6x performance boost with good old stateful servers). Calvin French-Owen lands the perfect reality check: AI agents don't remove the human job of thinking—they just shift where you spend those mental cycles.
Simon Willison delivers again with not one but two bangers: Claude Skills might be a bigger deal than MCP, and Claude Haiku 4.5 is here to make your token budget happy. Practical prompting strategies from the C.R.A.F.T.E.D framework arrive without fluff, and Bun 1.3 ships as their biggest release yet (because of course it does).
On the tools front: Scribe OCR works so well you won't need another app, Nitro arrives as the universal server toolkit that actually makes sense, WAHA gives you a self-hosted WhatsApp API in under 5 minutes, Cloudflare Sandbox is building the future of dev environments, and Zero drops a query-based sync engine that might just be the local-first breakthrough we've been waiting for.
Also in this issue: GraphQL myths debunked after nearly a decade, Vite+ unifies your entire JavaScript toolchain, Den walks through GitHub Spec Kit, the fern fractal teaches us that simple rules blossom into beautiful patterns, and Ryan Carniato explains what comes beyond signals.
Enjoy!
