Anthropic

The first time I used Claude Code to refactor an entire module, I had an almost mystical experience. I described what I wanted, went to grab a coffee, and when I came back there was a pull request with 14 changed files, updated tests, and a decent commit message. “This is magic,” I thought. It’s not magic. It’s a while loop. Michael Bolin from OpenAI recently published an article breaking down the internal workings of Codex CLI. And it turns out the secret behind AI coding agents isn’t some revolutionary algorithm or mysterious neural network. It’s a loop that calls an LLM, executes tools, and repeats until there’s nothing left to do. ...

A few weeks ago, I published an article explaining why 99% of what you send to Claude is already cached. KV tensors, VRAM, local SSDs — the full internal machinery. But I left out the part that hurts the most: the bill. Because prompt caching seems like a sweet deal until you look closely at the numbers. And then you realize that you’re paying to save. The cost paradox Let’s crunch the numbers. With Claude Sonnet: ...

For months, I’ve been running Claude Code tasks using a homemade cron. A Bash script that starts a headless session, feeds it a prompt, waits for it to finish, and then closes. It works. Barely, but it works. I’ve got it up on GitHub if anyone’s interested. Then on Friday, with version 2.1.71, Anthropic introduced /loop. A native scheduler. Built directly into Claude Code sessions. My first reaction was: “They killed my project.” ...

On February 25, 2026, Anthropic announced Remote Control for Claude Code. The idea: fire up Claude Code on your terminal, sit back on your couch with your phone, and continue the session through claude.ai. No SSH. No tmux. No remote terminal windows. Cool. In theory. Because in practice, when I enabled it (/rc in the terminal), I got a URL, opened it on my phone, logged in… and claude.ai hit me with a “this feature is not active in your organization.” February 2026, Max 5x account, paying religiously. And nothing. ...

I’m building Tokamak, a menu bar app for macOS that monitors your Claude Max quota. A couple of weeks ago, Anthropic published this in their Terms of Service: “You may not use OAuth or similar authorization mechanisms to allow third-party applications to access Claude on behalf of users.” And there I was, reading Claude Max quota using browser cookies to call an undocumented endpoint, staring at the screen thinking: “What now?” ...

I’m building an app that monitors my token consumption in Claude Code. A few days ago, looking at the raw numbers, I found this: cacheReadInputTokens: 4,241,579,174 inputTokens: 1,293,019 Four billion two hundred million tokens read from cache. One million three hundred thousand “fresh” tokens. That’s a 99.97% cache hit rate. My first reaction was thinking something was broken. Nobody has a 99% cache hit rate. Not Redis. Not Cloudflare. Not your mom when she claims she already knows what you’re going to ask for dinner. ...

A 100-Megabyte Binary for a CLI Anthropic just announced that Claude Code is now available as a native build. Translation: a binary executable you can install with a curl command that doesn’t need Node.js. Sounds good, right? One command, no dependencies, background auto-updates. Any CLI tool’s dream. But there’s a catch: the binary weighs 100MB. To put this in perspective, the git binary weighs about 3MB. curl is less than 1MB. Even Go, which has a reputation for generating fat binaries, rarely exceeds 15-20MB. ...

The Surprise of 10 GB You install Claude Desktop on your Mac. Everything seems fine; the app doesn’t take up much space. But one day, you check your disk and find this: ~/Library/Application Support/Claude/vm_bundles/claudevm.bundle 10.8 GB. Yes: one single file called claudevm.bundle, tucked away in Claude’s vm_bundles folder, taking up almost eleven gigabytes of your disk space. Ten gigabytes for a chatbot? What does it contain— the extended edition of The Lord of the Rings trilogy? ...

The news nobody saw coming Last week, while you and I were peacefully struggling with node_modules, Anthropic dropped a bomb: they bought Bun. Yes, the company behind Claude decided their future involves a JavaScript runtime written in Zig by a guy who thought “what if Node, but fast?” Claude Code just hit a billion dollars in revenue, and apparently the first thing you do when you have cash to spare is buy development tools. ...
