A whole plan, in one go.
The agent writes the GUI steps together. The runtime carries them out and returns the requested observations.
H HOLD MY SANDBOX LINUX · V0.2.0
Your agent’s desktop.
Your computer, still yours.
Let the agent work the interface.
Keep getting on with your day.
hms lets Claude Code and Codex operate browsers and desktop apps in a graphical session of their own, without taking over your screen, mouse or keyboard.

01 ONE TASK. SEVERAL APPS.
From “can you…”
to “here it is.”
Describe the job in your usual conversation. Your agent can read a page, work in an application and check the result through the same interface.
AN EXAMPLE REQUEST
“Read the event details and save a short briefing in a document.”
One agent. Its own session.
You keep your desktop.

02 FEWER ROUND TRIPS
Let code handle
the mechanics.
When the steps are known, hms can execute a complete program locally. It waits for real readiness events and checks effects, instead of asking a model what to do after every click.
Read what is actually there.
Page text and accessibility data offer shortcuts. Pixels and text recognition cover interfaces without that structure.
Explore when the way is unclear.
An optional navigator can work through an unfamiliar interface. The calling agent can observe, steer and stop it.
03 PUT IT TO WORK
A session of its own.
One install away.
The current Linux release is tested on CachyOS with KDE Plasma 6.8 on Wayland. Other distributions are untested. Check the requirements before installing.

curl -fsSL https://lavett.dev/hms/latest/install.sh | shInstalls into its own Python environment and registers with Claude Code and Codex. The installer never uses sudo.
macOS is in testing and is not qualified for this release. Windows is not available.
04 KNOW YOUR WORKSPACE
A little separation.
A clearer boundary.
Your files & session
On Linux, the session hides your home and exposes other files read-only, with ~/hms-exchange as the shared writable folder. Services your account can use, such as Docker or libvirt, remain reachable and can change files with their own rights.
Your AI & subscription
hms uses the CLI sign-in you already have. Your provider receives what the agent sends it. The navigator stops when the CLI reports a subscription limit; the step that reaches the limit can still be billed as extra usage.
