# Dozer Sandbox 0.33 - see what your agent is doing

*11 October 2026 · Release news*

It's on the [stable channel](https://dozable.com/docs/install-upgrade-uninstall) now, as 0.33.1. Here's each change.

## See what the agent is doing

Claude Code and pi now tell Dozer what they're doing: **working**, **done**, waiting for your answer, or stopped by an
error. Dozer shows it in the dashboard wherever the session appears, so you can leave an agent to work and glance
back when it matters.

While the agent works, its tab shows **working**, and a dot beside the sandbox in the sidebar says something is
going on.

When the agent stops to ask you something, such as permission to run a command, a notice appears at the top of the
dashboard saying what it wants, with an **Open** button that takes you straight to the session. You see it on
whichever page you're on.

When it finishes, the tab says **done** and the notice tells you so. The same status shows on every tile in
**All sessions**, so with several sandboxes running you can see at a glance which agent is still busy and which is
waiting for you.

The status shows while the dashboard is open (`doz ui`). Claude Code needs version 2.1.295 or later, and pi 1.1.0 or
later.

### How it works

It uses a terminal escape sequence: bytes mixed into a program's output that the terminal acts on instead of
showing, the same way programs set a window's title or colours. This one is **OSC 7501**, for program status
([Mitchell Hashimoto's write-up](https://mitchellh.com/writing/program-status-osc7501)).

- **The handshake:** a program asks the terminal whether it understands the sequence (`ESC ] 7501 ; ? ST`). If the
  terminal answers, the program reports its state (working, done, blocked or error, with a short message) each time
  it changes.
- **Inside the sandbox:** every session runs under a small holder process that reads everything the program writes,
  whether or not anyone is watching. It answers that question, keeps the latest report, and passes the output on
  unchanged.
- **On your Mac:** the Dozer host watches each running session's status, and the dashboard draws it.

Nothing is read from the screen or guessed: Dozer shows exactly what the agent itself reports.

## `doz upgrade`

One command moves you to the newest version on your channel. It asks first; `-y` skips the question.

```sh
doz upgrade
```

## The dashboard in the background

`doz ui --detach` runs the dashboard without holding a terminal, and `doz ui stop` stops it from any terminal.

## Staying in touch

Setup now ends with an optional sign-up for release news, early access, and tips and tricks, by email. Skip it, or
sign up later with `doz signup`.

## Fixed in 0.33.1: the agent can write your workspace again

Since 0.30, an agent in a sandbox could read a shared project folder but not change it, and `git` refused the folder
("dubious ownership"). 0.33.1 fixes it. After upgrading, a sandbox that was running, asleep or hibernated needs a
`doz shutdown NAME` and then `doz start NAME`; one that was shut down picks up the fix at its next start.

## Upgrade

```sh
doz upgrade
```
