Just shipped something I'm really excited about in @𝗇𝗎𝗑𝗍𝗃𝗌/𝗆𝖼𝗉-𝗍𝗈𝗈𝗅𝗄𝗂𝗍: Code Mode. The idea: instead of the LLM calling your MCP tools one at a time (and resending ALL tool descriptions every single round-trip), it writes JavaScript that orchestrates everything in one go. Loops, conditionals, Promise.all, real control flow, not 8 separate LLM turns. With 50 tools the token savings are insane: -81% on tool description overhead alone. And the best part? Your existing tools don't change at all. One line: `experimental_codeMode: true` Runs in a secure V8 sandbox thanks to @rivet_dev's secure-exec, perfect timing with their launch yesterday. mcp-toolkit.nuxt.dev/advanced/code-…






Interviewer: Do you know system design? Candidate: Yes. Interviewer: Design a system for 100 users. Candidate: Microservices, load balancer, queues… Interviewer: You’re solving for millions. I asked for 100.



We've reached an agreement to acquire Astral. After we close, OpenAI plans for @astral_sh to join our Codex team, with a continued focus on building great tools and advancing the shared mission of making developers more productive. openai.com/index/openai-t…
