self-harness: harnesses that improve themselves
spoiler alert, it's all loop engineering!
1. weakness mining - run agent and observe failures
2. propose improvements to the harness
3. confirm improvements are beneficial and don't cause other regressions
and then you loop!

Here are the skills that ship with Xcode 27.
Apple did a fantastic job with these (no surprise) from what I've poked around and looked at. Baseline SwiftUI guidance, and nuggets on how to use the new stuff like the reorderable APIs.

🧵 Announcing iSH ARM64 — native Linux on iPhone & iPad, open source.
A fork of @iSH_app that adds a same-architecture threaded-code interpreter (codename Asbestos) for AArch64 Linux on Apple Silicon.
1/ iSH ARM64 runs AArch64 Linux on ARM64. 3–30× overhead vs native, down from 15–100×.
2/ 48-bit virtual address space. Unlocked V8, Go, and Rust on iSH ARM64 now.
3/ Node.js 22 now runs on iOS. With --jitless injection.
npm install. npx. create-next-app. All working.
4/ Built for AI agent orchestration on iOS. iSH ARM64 shipped as the Agent Shell Sandbox inside OpenMinis — stably running Linux workloads for 10,000+ users.
5/ Compatibility: 205/205 tests pass. 18 categories — Core OS, Python, Node.js, Go, Rust, Perl, Ruby, SQLite, Git, SSH, Editors, Build tools, Media, Crypto, Signals, and more.
The code is open. The 10,000 users are production.
