I'll be giving the the Day 2 opening keynote at AI Engineer World's Fair on July 1st at 9am. Hope to see you there, here's a quick preview

Claude Code can now upload and edit HTML artifacts that you can share with your team or other Claudes! Starting with teams so you can share internally with your team, coming to Pro and MAX plans soon!

Slack now renders HTML attachments instead of just showing it as text 😭🙏

Lots of people asked how I used Fable to edit its own launch video so I made a video about that! TLDR it wrote a lot of code & tool calls to use transcription services, ffmpeg, do colorgrading, use the figma mcp, make remotion UI and render it. I didn't touch a video editor. (1/2)

at Code w/ Claude Tokyo! say hi if you see me around

Fable is a step-change in models, and I hope it changes how you work with Claude. More to come in a series of posts on how it’s reshaped our work, but the TLDR: it’s time to be more ambitious.

An app can be a home-cooked meal (2020) personal software was a bit early in 2020 but in 2026, it really can be as personal as a home cooked meal, or a handwritten letter https://www.robinsloan.com/notes/home-cooked-app/

If this prompt feels well written to you, it's because Suzanne is a writer in her little spare time! You can read her short story, Mall of America here: https://suzannewang.com/mall-of-america It's one of my favorite short stories about the human condition that happens to involve AI.

Workflows are the biggest upgrade to Claude Code’s capabilities since skills and subagents. I dove deep into it with @sidbid to figure out best practices, examples and more.  I’m particularly excited about the non-technical tasks it enables for Claude Code.

been asking others at Anthropic how they stay in the loop with Claude and fully understand the work being done this is one of my favorites from Suzanne:

I think you’ll really like Opus 4.8 It’s as smart as its benchmarks show but expresses and utilizes that intelligence in a warm and collaborative way. Workflows are a great way to utilize it- I’m hooked. Article on that soon.

Eid Mubarak!

the basic trick to using Claude Code for non-technical work is to put a bunch of files in a folder and tell it can write scripts + make HTML

my main takeaway from the Bun rewrite is that legacy codebases will be incredibly valuable as a source for "distilling" code into new forms every game should be crossplatform, all legacy software should work on the web, we don't need COBOL anymore

every now and then I remember you can run the "please save me money" prompt and it will actually work

the future is bright, lets get to work

continuing my HTML era, I had so much fun talking with Claire at Code w/ Claude about staying in the loop with long running agents

a prompt I've been using a lot recently: implement <SPEC> and while you do, keep a running implementation-notes.html file (or markdown) with decisions you had to make weren't in the spec, things you had to change, tradeoffs you had to make or anything else I should know

tired: I brought my work laptop and my personal laptop wired: I am dual wielding

HTML continues to be undefeated

Agent view is the best Claude Code native way to manage multiple sessions, kind of like tmux built for CC. We spent a lot of time getting the details right, I hope you enjoy it.

you can make something good ty @aadilpickle @FarzaTV

Jarred tried rewriting Bun in Rust and it passes 99.8% of the existing test suite we're not being ambitious enough

HTML is the new markdown. I've stopped writing markdown files for almost everything and switched to using Claude Code to generate HTML for me. This is why.

"everyday we're trying to obtain more compute to pass on to you, we're sorry if it takes sometime but we're going to acquire as much as we can" you heard the man

Claude in Space 🤞

We're winding back our peak hours limit reduction and doubling 5 hour limits. Excited to partner with SpaceX to bring you more compute and we'll keep pushing to bring you the best coding agent in the world.

See you all soon! We've got some fun announcements ahead. I'll also be doing a workshop on "how we Claude Code" with some workflows I'm excited to share. Don't worry if you're not there, everything will be recorded and uploaded.

we're doing a lot more of this, hunting down some of the most annoying bugs in Claude Code let me know if you have any white whales

This account can now be found on the fediverse at @trq212-x.bsky.social@bsky.brid.gy

one of my favorite quality of life features

We’ve heard your feedback and we’re working on making it easier to follow everything that’s happening with Claude Code. First, we’re introducing @ClaudeDevs, the official channel to follow for all updates on Claude Code and the Claude platform.

a quick fix if you saw higher rate limit usage in Opus 4.7 today- hope you enjoy trying it out

Opus 4.7 is a model I’ve loved working with in Claude Code. It’s more agentic and instruction following but also incredibly smart and creative. I think it takes a slight adjustment to get used to, but it's so good with auto mode.

I edited the intro because I realized I buried the lede originally- The 1M context window is a double-edged sword. It allows Claude to do more complex tasks but it can also leads to more context pollution if you don't manage your session well. This is how you do that:

Have you tried the new Claude Code renderer? What has your experience been like? If you haven't, you can enable it with: CLAUDE_CODE_NO_FLICKER=1 claude

there's a turbotax connector in Claude Code now, so glad I procrastinated on taxes 😭

New in Claude Code: /ultraplan Claude builds an implementation plan for you on the web. You can read it and edit it, then run the plan on the web or back in your terminal. Available now in preview for all users with CC on the web enabled.

you'll need to explicitly prompt Claude Code to use it, but the Monitor Tool is super powerful e.g. "start my dev server and use the MonitorTool to observe for errors"

I think "prompting" will keep being an incredibly high-leverage skill, like writing or public speaking. It is the skill of talking to agents, mediated by the harness. My main goal is to grow the bandwidth between humans and agents, to help us understand each other better.

I want to do some streams where I work with non-technical people using Claude Code to figure out how they might be able to improve their process. My feeling is that just a few tips could make a big difference in efficiency. Any mutuals interested?

Managed Agents is the first 'agent in the cloud' API that has the right mix of simplicity and complexity. Implementation details like how you manage a sandbox are abstracted, but you have a lot of control over the actual execution of the model.

done about 10 of these calls so far + looked at more transcripts many learnings but one of the biggest is that it's very easy to spend a lot of tokens on open ended verification that doesn't make your output better I'll try and write more on how to do it efficiently

Doing a workshop on my technical writing process in SF in 2 weeks, hosted by friends @MilksandMatcha and @swyx. Would love to see you there! Link below.

I put a lot of heart into my technical writing, I hope it's useful to you all. 📌 Here's a pinned thread of everything I've written. (much of this will be posted on the Claude blog soon as well)

Excited to talk to you tomorrow @ 12pm PT. Adam will be showing off a demo of a new feature we haven't released yet!

I want to do a few more of these calls. If your MAX 20x plan ran out of tokens unexpectedly early and you're willing to screenshare and run some prompts through Claude Code please comment. Trying to figure out how we can improve /usage to give more info.
