Here's a step-by-step process to kill all the bloat from your Claude Code system prompt: 1. Run a proxy so you can see exactly what gets sent to Claude Code (included in the article) 2. "Fuck, there is so much cruft in there" 3. Use my settings.json to kill all the bloat Down t…↗

I'm open-sourcing my Agent Skills library. 75 skills for Codex, Claude Code, Cursor, and other agents, focused on web design, landing pages, motion, WebGL, UI styles, and assets. A few favorites: - Video to Super Prompt Turns a screen recording of a design, landing page, or an…↗

Do this on your last day with Fable You can extract Fable 5's intelligence out of the model before it's gone... and i'm going to teach you the 5 workflows that do it, with every prompt ready to paste because tomorrow Fable 5 leaves your subscription it moves to pay-per-token c…↗

The Taste skill + impeccable.style is one of the easiest ways to turn prompts into polished, non-AI-slop designs and image gen. Pair it with Codex or Claude Code to recreate almost any landing page from a video or full-page screenshot.↗

We've put together a short history of how Claude Code came to be, told by the people who built it and the early users who helped make it what it is today. anthropic.com/features/makin…↗

Smol tip: /𝚌𝚍 moves your running Claude Code session to another directory without restarting. Your conversation and context come with you, and Claude picks up the new project's CLAUDE.md.↗

Everyone's always talking about agentic coding harnesses: Claude Code, Codex, OpenCode, Pi... the list goes on. But what's the difference between all of them? What even Is a harness anyway? In this thread, we'll take a look under the hood. (1/5)🧵↗

a fun workflow for prepping a talk: > record a draft video without a script > have Claude Code turn the video into a Notion page with slides + transcript of what I said > ask people for feedback on the video; Claude processes their notes and attaches things as inline comments in…↗

figuring that out with Fable now, i first started by just brain dumping everything that i want to have agents running for i think this might turn into an Executor feature of 'Agents' where you store a: - name - goal - allowed toolset and then it just handles dispatching an API…↗

dear claude code & codex teams, please, for the love of god, where is my executive super assistant that has: (1) a deep understanding of me via great memory, just pack 200k context with every chat. you can build this personal store from past chats, but also i'll just give you al…↗

A conversation with Boris Cherny and Cat Wu on the path from Claude Code to Claude Tag, and how it spread from engineering to the rest of Anthropic. Claude Fable 5 is now available in Claude Tag.↗

🚨 Announcement: I’ve co-developed a live course with my frequent collaborator and new Head of Education, Colin Matthews. It's called Become an AI-Native Builder, and you'll learn how to use the latest AI tools—including Codex, Claude Code, Cursor, and other popular AI tools—in…↗

Your AI's Memory Is Quietly Making It Dumber (I Cut Mine to 6 Files) I gave a talk last week and said it out loud: delete that memory, agent. When your agent learns a lesson, do not park it in some private memory file. Make a pull request that improves the skill, so the fix help…↗

I'm now running GLM 5.2 as my default model in claude code + cursor, and it's cost me *checks notes* $3.36 Today's ep of How I AI is my first reviewing an open weights model, @Zai_org's GLM 5.2 which (so far) is giving me Opus vibes without the opus $$$ I cover - how to set up…↗

best writeup i've seen on steering Claude Code. every way you instruct it costs a different amount of context, and it takes some more seriously than others. clear enough that you can drop the article into Claude Code and have it clean up your own config. …↗

One interesting trend: I’m seeing *so many* VC-funded, internally built infrastructure and bootstrapped solutions around “building a context layer for engineering teams.” Aka trying to solve the problem of “if only eg Claude Code had the context from all your other systems”↗

WTF Is a Loop? Part 2: The 15 Loops People Are Actually Running (and the Commands to Steal Them) Earlier this month I wrote [WTF Is a Loop? Peter Steinberger vs. Boris Cherny](x.com/mvanhorn/status/2063865685558903149), which did 3.6M views on what a loop even is. This is the se…↗

New in Claude Code: Artifacts. Interactive pages built from your session, like a PR walkthrough or a living project dashboard, shared with your team at a private link. Available in beta on Team and Enterprise plans.↗

Given how impressed I was with Cursor’s Thermo-Nuclear Code Quality Review skill, I decided to create a similar one, but specifically for animations. /review-animations to review, and /emil-design-eng to build animations. They complement each other well emilkowal.ski/skill↗

New in Claude Design: it stays on brand with your design system across projects, lets you edit directly on the canvas, syncs with Claude Code, and connects to more of the tools you already use.↗

Our latest economic research introduces a framework for tracking Claude Code as it scales. Who is using Claude Code, and what are they using it for? How is the value of tasks changing? And how much does domain expertise shape whether a session succeeds? …↗

Introducing /visual-plan - a skill to generate rich, visual plans for Claude Code and Codex. Plan mode in Claude Code is incredible. But I always find my eyes glazing over when it gives me this huge markdown essay in my terminal. I found I can make much better visual plans wit…↗

Anthropic is losing the mandate of heaven ## Four months ago, in early February, Anthropic was the darling. OpenAI was the dominant behemoth to root against. Over the last 1-2 years, we'd seen the Sam ouster / return drama, Ilya and Mira had left, the company had raised $40B, h…↗

After two days with Claude Fable 5 the best way I can describe it is "relentlessly proactive" - here's an example where I dropped in a screenshot of a bug and it span up custom CORS Python servers and used pyobjc-framework-Quartz to capture screenshots …↗

Designing loops with Fable 5 Mythos-class models like Claude Fable 5 have changed the way many of us work at Anthropic. I want to share two tips for getting the most out of this class of models. Self-correction loops There’s been a lot of interest in loops recently. @bcherny […↗

Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a codin…↗

Claude Fable 5 changed how we work on the Claude Code team day to day. We used to verify that Claude did the work right. Now we verify that it's doing the right work. Here’s the 3 biggest changes:↗
