T3 Code for agentctl Sandboxes

A fork of T3 Code that runs agents in agentctl Sandboxes. It follows upstream's stable releases; for what T3 Code is and how to use it, see upstream's README.

Getting started

You need Git and Node 26. Clone the repository:

git clone https://github.com/martinothamar/t3code.git
cd t3code

Then install the desktop app, either the latest release:

node scripts/fork/install-desktop.ts

or a build of the checked-out commit, which also needs vp, Rust from rustup and your platform's build tools:

node scripts/fork/install-desktop.ts --from-source

With Make installed, make install and make install-source run the same commands; make lists the shortcuts. In PowerShell, .\make-install.ps1 and .\make-install.ps1 -FromSource do. Where PowerShell's execution policy blocks scripts, run one as powershell -ExecutionPolicy Bypass -File .\make-install.ps1. Installing has the details.

To connect to Sandboxes, run agentctl ssh-config install once, and give your Agents access: [{type: ssh}] in their manifests. They then show up in the app; see agentctl Sandboxes.

Updating

We force-push main when updating the fork, so update your checkout with a fetch and hard reset instead of git pull.

git switch main
git fetch origin
git reset --hard origin/main

# Or
make pull

In PowerShell, .\make-pull.ps1 does the same.

Developing the fork

agents/dev is an agentctl Agent for working on this fork. Start at AGENTS.md. Pull requests and issues go to this repository, not upstream.
