Claude Code on desktop lets you select DOM elements directly, much easier than describing which component you want updated! Claude gets the tag, classes, key styles, surrounding HTML, and a cropped screenshot. React apps also get the source file, component name and props

💡 Using Next.js's Intercepting Routes can be useful if you want to show a route while keeping the context for the current page! E.g. we can render an overlaying modal on soft navigation and a standalone page on hard navigation, which requires a full page reload:

🚗 Just drove Austin → SF with Tesla Full Self-Driving the entire(!) way Handled everything perfectly; insane traffic, extreme desert heat, steep curvy mountain roads at night, even forest fire smoke. So close to living in my ideal sci-fi world lol Bullish on American tech 🇺🇸

🪄 bun natively supports macros run a function at build time and inline its return. only the result gets bundled, not the function! ✦ precompute constants ✦ inline env, platform, version values ✦ fetch at build time (async supported) ✦ … many other small build-time tasks!

Opus 4.6 lets you set the effort level Not every task needs high reasoning. For simpler tasks you can set it to low or medium. Claude thinks less (or skips it entirely), makes fewer tool calls, and gives more concise answers Lower effort = faster responses with fewer tokens!

Claude Code now supports agent teams (in research preview) Instead of a single agent working through a task sequentially, a lead agent can delegate to multiple teammates that work in parallel to research, debug, and build while coordinating with each other. Try it out today by enabling agent teams in your settings.json!

Claude Code Desktop now supports --dangerously-skip-permissions! This skips all permission prompts so Claude can operate fully autonomously. Great for workflows in a trusted environment where you want no interruptions, no approval prompts, just uninterrupted work. But as the name suggests... use it with caution! 🙏

Claude Cowork is also super useful for editing files You can just describe what file you're looking for (e.g. "a video with a squirrel") and run ffmpeg based on simple instructions, even if you don't have any experience with editing/converting files

Claude Cowork now supports the Slack MCP on all paid plans! The Slack connector is by far my favorite feature. I use it every morning to catch up on what I missed, highlight important messages, and draft replies for me to review before sending. Huge time saver.

Using the "Control your Mac" connector with Claude Cowork is so nice. It's an AppleScript MCP that lets Claude control Mac apps and system functions Finally found a good way to prompt Apple Keynote slides!

Cowork now supports plugins! Super powerful It's the same concept as Claude Code plugins but great for non-eng roles, like research, marketing, legal, sales, etc.

the new --cpu-prof flag is a really nice way to see how much of your time Bun is spending on the CPU ⚡ you can open the profile directly in VSCode/Cursor/Chrome DevTools. also makes it easier to compare how your script performs in Bun vs Node!
