Author here, I built this because my agents could not use TUI or interactive CLI software. Think puppeteer for TUIs.

If you've ever asked Claude Code, codex, opencode, etc... to make logical commits from a bunch of changes you might have seen them struggle with moving files around, deleting files when a simple `git add -p` would have let them work through the changes interactivly. ht (the binary name) allows them to spawn their own terminal and drive it similar to puppeteer, sending keys, viewing a snapshot of the terminal and making a decision.

Some other use cases are also solved from CI/CD to making nice demos (it can export images or the format used by asciicast for making videos of the session.

It's powered by libghostty so it has support for all the stuff a modern terminal can do (full color, mouse clicks, etc...) and I've had a lot of fun letting claude run wild and even play games like nethack.

Happy to answer questions, and of course let me know if you run into any issues!

Fourth thing in a row they've announced that I wanted to try and couldn't.

Start designing at claude.ai/design.

That link is redirecting me to https://claude.ai/404, anyone else?

Have same issue, it redirect to https://claude.ai/login?returnTo=%2Fdesign then back and redirect to https://claude.ai/login?returnTo=%2Fdesign again, looping...

It works for me. Check again?

Seems they jumped the gun releasing this without a claude code update?

     /model claude-opus-4.7
      ⎿  Model 'claude-opus-4.7' not found

claude-opus-4-7

It seems they nerf it, then release a new version with previous power. So they can do this forever without actually making another step function model release.

Same, if we're punished for being on the highest tier... what is anthropic even doing.

You're not, it wasn't released yet. Update to 111 and you'll see it (i'm on Max20, i do)

Heck, mine just automatically set it to 4.7 and xhigh effort (also a new feature?)

Thanks, I was already on the latest claude code, I just restarted it and now it's showing 4.7 and xhigh.

xhigh was mentioned in the release post, it's the new default and between high and max.

     /model claude-opus-4.7
      ⎿  Model 'claude-opus-4.7' not found

Just love that I'm paying $200 for models features they announce I can't use!

Related features that were announced I have yet to be able to use:

    $ claude --enable-auto-mode 
    auto mode is unavailable for your plan

    $ claude
    /memory 
    Auto-dream: on · /dream to run
    Unknown skill: dream

I think that was a typo on my end, its "/model claude-opus-4-7" not "/model claude-opus-4.7"

That sets it to opus 4:

/model claude-opus-4.7 ⎿ Model 'claude-opus-4.7' not found

/model claude-opus-4-7 ⎿ Set model to Opus 4

/model ⎿ Set model to Opus 4.6 (1M context) (default)

A little off topic, but did Anthropic distill from an older OpenAI model? All the sudden over the last few days I'm getting a ton of em dashes in claude code responses!

It gets really fun when you prompt them to update their BOT.md, also they get access to previous run results so they continually "learn" from mistakes or investigate changes.

This is very cool, I just wonder where they get the crossing data!

I'm guessing from the AIS Vessel Tracking (mentioned in their data sources)- https://www.vesselfinder.com/realtime-ais-data
