    When Claude Code fetches Bun’s docs, Bun’s docs now send markdown instead of HTML by default This shrinks token usage for our docs by about 10x

    Super excited to release Plugins for Claude Code. Plugins are the easiest way to share and install bundles of agents, slash commands, MCP servers, and hooks. Something we saw people doing already, now we made it even easier.

    Thanks @swyx + AI Engineer World's Fair for hosting me for a talk on the big stage last week! I did a speed run through the evolution of coding UX since the 1950's, and where I think we're headed. Video: youtube.com/watch?v=U-fMsb… Slides: docs.google.com/presentation/d…

    TypeScript and Python SDKs for Claude Code are here. Use the same agent and tools as Claude Code, and build them into your own agents and workflows.

    Thanks to Claude Code users for contributing incredible feedback! We just shipped more features based on what we’re hearing from you all. See Cat’s thread for details on auto-accept mode, auto-compact for context, and filepath autocomplete.

    Three more features for Claude Code today: First, auto-accept mode. Press Shift+Tab to toggle on auto-accept for file edits. This reduces friction while keeping you in the driver’s seat—you can tab in/out of auto-accept mode anytime.

    Introducing Sonnet 3.7 and Claude Code, Anthropic’s new agentic coding assistant. The team and I have been hacking on Code for a while — can’t wait to hear what everyone thinks.

    We auto-compact for you when using the SDK, so you don't need to. To grab stats yourself, read assistant_message.usage.
