I'm developing apps for Apple platforms for the first time in 16 years so stop me if this is nuts, but the best feedback loops I've managed are when I've made the Mac build the primary one. No simulator jank. No waiting on devices.

Claude Code doing a better job self-verifying

I like my doctor but his office is always full of sick people.

Sometimes for old times' sake, I'll Google for something instead of just asking an AI agent.

PSA: iPhone Air's microphone is located on the left side of the bottom edge of the device, AKA where a right-handed person's pinky would naturally rest when gripping the phone with one hand.

Anyway, that's why all your videos sound like shit. You're holding it wrong.

Added a /prove skill to my prove_it library. It pushes Claude Code to go beyond merely analyzing source and running tests to demonstrate the code is working.

Example: it spun up a complete example project and ACTUALLY proved my cached test runner works github.com/…

One happy accident of the fact that Claude Code Opus 4.6 turns seem to reliably take 3-5 minutes in my experience is that it's proving to be the perfect companion to a strength training workout.

I just write prompts between sets.

Free idea: hyperbolic_links.

Let users create symbolic links mapped to HTTP resources. Since you can't literally link a file to a URL without changing the actual file system, hyperbolic would centrally handle journaling, cache/etag, updates.

My prove_it CLI is already proving valuable. Just watched Opus 4.6 complete an hourlong rewrite without me… ONLY because 6 times prove_it's own script & agent hooks blocked Claude from prematurely declaring victory. It's letting me focus on WHAT, not HOW github.com/…

A recurring theme in coverage on the effect AI will have on wealth/income inequality suggests there's a strong case to be made that AI is going to be bad for poor people.

I have nothing useful to add to that discussion, so here's a word I just invented: Agentrification

Whether or not the Xcode agent is any good (I'm dubious), the fact Xcode itself is exposing first-party MCP tools is great news—trying to get Claude/Codex to do fucking anything right in iOS is agonizing. developer.apple.com/…

Two new searlsbrew projects today:

• prove_it: verification-oriented baseline rules and hooks for Claude Code github.com/…
• scrapple: scrapes and indexes Apple's SDK docs/videos/sample code github.com/…

Early in my career, I met a few COBOL developers who came out of retirement in the run-up to January 2000, getting paid $300+ per hour to remediate Y2K bugs when nobody else was left who knew COBOL.

Suspect a similar trajectory for highly-skilled, well-rounded "pre-AI" engineers

Coding agents are a TON of fun if you are (1) extremely ambitious and (2) have middling standards.

They are still fun if you are (1) extremely ambitious and (2) ruthlessly exacting standards, but markedly less so.

Now that I've spent ten hours with Claude Code after a few months with Codex CLI, I can say with confidence:

• Claude is much much faster
• Claude makes much stupider mistakes much more often, even with Opus 4.5
• With either agent, I end each session frustrated and exhausted

LOL, also apparently Adobe Premiere on iPad will frequently silently fail when generating captions. And there's no way to export them as text, subtitle files, etc.

This is starting to seem like bad software that nevertheless gets recommended to people ceaselessly.

Trying Adobe Premiere for the first time since version 6.0 in 2002. Paid for Creative Cloud Pro. First thing I tried: start a project on iPad, sync via cloud, finish on my Mac.

LOL, nope. Their "cloud" can't sync projects. It's just a one-way, manual upload and import. And slow.
