I’ve gotten my Claude Code setup to the point where I am no longer doing data entry around credentials and it is glorious! Rarely do I need to go to my computer now, so I asked my orchestrator session to write up the setup in a post for your agents! daniellemorrill.com/blog/how…

Now in @matte_app your agents can write Code clips, so your mockups and screen recordings can have complex animations and shaders in the canvas with them. Graphs, backgrounds, shapes, particles… anything you want. Code clips automatically get custom controls so you can tweak them yourself and stay in control.

The Matte MCP is such a great way to get great videos with barely any effort. Matte auto-animates the iPhone Duo recordings and your AI agent takes care of the rest.
Undolly is almost ready for iPhone Duo. Here's a sneak peak made with @matte_app

Matte is the best way to make your iPhone Duo videos. Record the simulator and ask Claude to do the rest via MCP!

Oh come on. Quick look at colorshift (13x faster): HashMap in hot loop (unoptimized Rust vibeslop) is slower than indexed arrays (ASM). No shit. Numbers like 17x should raise eyebrows but reading the comments nobody is thinking anymore. This AI psychosis has fried people's brains
I ported the Omarchy screensaver engine (ttfx) from Rust to x86-64 assembler, and it's up to 17x faster!! One-shot translation by Opus 5.5. We keep drilling until the agentic drill bit hits bedrock! github.com/omacom/ttfx/pull/…

Final takeaway: iOS devs should almost always start new projects in bazel, agents; and huminity will love you. It's way easier than anytime before.
finally, Xcode isn't hermetic on its own, currently tuist engineers are doing interesting work to fix this by a new tool they created called `once` which is a simplified bazel. we wanted something tested, and scalable, mantinaed by top notch engineers and companies around the world.

🧵 Re: Which features Tuist did not have that you needed ?, The answer will be quiet long and detailed one. (Also: photos of Logroño as well 🍇) The summary is: there were technical limitations for tuist, and non technical ones, both contributed to our final decision.
Replying to @Bitomule
We evaluated Tuist and would choose Bazel again for our project. Its capabilities and long-term foundations convinced us. We're still moving more work into Bazel, and local machine capacity is becoming our next constraint.

Opus 5.5 is the result of your feedback. It communicates clearly, it's cheaper per token than Opus 5.0 with the intelligence of Fable 5.1, it’s very token efficient and works across every effort level. We're also increasing 5h rate limits & giving you a banked reset.
Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

If you can, support a developer today by leaving an honest review on one of their apps. It takes less than 2 minutes, costs nothing, and you have no idea how much it can help an indie developer. Small gesture. Huge impact.

I can’t express how incredible has been the talk that @KallamMostafa and @Bitomule have presented in #nsspain26. I need to watch it again to take notes and analyze if we can use Bazel in our team. Thank you so much!! ❤️❤️❤️

We're exploring a new way to let you extend and customize Claude Code: Function Hooks. Here's a couple videos showing what you'd be able to do. It hasn't shipped yet, we'd love feedback on this on our GitHub issue.

You can now set Claude Code's output style to Concise. Claude leads with the result, keeps responses short, and still gives full detail when you ask. Turn it on in /config → Output style, or set "outputStyle": "Concise" in settings.json.

New in Claude Code: your sessions can now message each other. Instead of having to re-explain yourself in another session, you can now tell Claude to do it. It sends a summary (not your history or files), and the other session picks it up mid-task.
