Tinkering with Claude @ Anthropic

[Dan Fein @dfeinition]

@lexxbarn I can help here!

Claude Duet asks before things go out. I say yes a lot.

We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent.

It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

Opus 5.5 x 🥞 x two dozen worlds

[Dan Fein @dfeinition]

I've posted about a dozen films and demos that Opus 5.5 made entirely in code.

People keep asking what I typed.

So I wrote it all down. The prompts, the steering, and what I learned along the way. https://t.co/P82Pnw3MsS

@NookWire Checking with the team, but is it possible for now to instead move those projects into a parent project folder that you allow?

[Dan Fein @dfeinition]

Your Claude Projects cloud session can now connect to a folder you approve on your computer.

The session stays in the cloud and only reaches for that local folder when a task needs it, reading and editing the files in place.

Starting to roll out today.

@LexnLin wowwww

[Dan Fein @dfeinition]

@mamuso How do we double down instead of unfollowing?

[Anthony Morris ツ @amorriscode]

thanks for the feedback on the Claude Code Desktop launch this week. we'll continue to iterate based on feedback (yes, group by folder is coming back). our small team is grateful to be building for so many of you!

Introducing Anatomy

Describe a machine in one line. Claude brings it to life.

- Interactive isometric wireframes you can rotate, inspect and explore
- WebGL shaders for fire, water, plasma and more
- Real 3D motion, with individual parts that rotate and move

Install it as an agent skill. Fully open source.

@theo Try claude projects! I find you can really flood it with messages and it’ll make sense of them all.

It’s changed the game for me because I now “prompt” like I talk in iMessage/Slack/DMs:

short msg
short messageee
short
short messssssage

[Dan Fein @dfeinition]

@kevin_t_ngo Wow! Little doodle cartoons!

[shadcn @shadcn]

Most of what I do in Claude Code now are in Projects.

@kevin_t_ngo Excited to see the 4D version next

[Dan Fein @dfeinition]

I’m excited for the new Claude Projects to continue rolling out.

[Dan Fein @dfeinition]

I’ve found that just by chatting and working naturally with Claude Projects, I end up teaching them.

Now it feels like I’m "prompting" less and talking more.

🧵 Here’s how:

[Dan Fein @dfeinition]

The more my Projects know, the more a short "prompt" gets me.

Because Claude's learning with me here I just get further, faster.
