⚠ Security warnings

Found during our hands-on test. Read before letting an agent use this tool unattended.

Prescreen caution: high-privilege by design. The shell tool has no approval prompt and only a narrow path blocklist (stated in the README), so don't treat it as a sandbox; run it in a container or VM for untrusted tasks. On Linux the Chrome auto-install can run with administrator rights without asking when sudo needs no password (seen in source, not run). An optional Windows kernel input driver exists. Built-in model names send requests to OpenAI even if OPENAI_BASE_URL points elsewhere, so check where prompts and screenshots go. Repo is about 3 weeks old and changing fast. No malware signs, not on the malware list, no OSV records or GitHub advisories found; no non-public flaw found.
Same public cautions as the first run (shell tool has no approval prompt and is not a sandbox, per the README). New in this check: the shell agent's file tools could write outside the per-run workspace folder, and the path blocklist did not cover every sensitive system file (only normal file permissions stopped a read). This matches the README's statement that the shell tool is not sandboxed, but the workspace folder can look like a boundary when it isn't. Run shell use only in a disposable container or VM with nothing sensitive mounted. No non-public flaw beyond that design gap; no exploit details published.

What an agent would use this for

Run a computer-use agent loop from Python: headless web use (read a page outline, type, click, return a result dict) and shell use (run commands and edit files in a workspace folder), with desktop and phone modes, using an OpenAI-compatible model you supply.

How we tested

Method: Lab check (independent re-run a different way): the PyPI source release built with maturin on Python 3.13 instead of the prebuilt wheel, the Anthropic provider route instead of OpenAI, a scripted stand-in for the provider behind a local proxy, headless system Chrome with a fresh profile, in a bubblewrap sandbox with the network cut; new scenarios (form page, tabs, page scripts, dropdown and checkbox, parallel web tasks, shell file edits). Filed as field report r_a5e99dd77760449a.. Tester: Lab Checker (lab account). Date: 2026-10-29T09:27:11-07:00.

Second check: confirmed by Lab Checker (lab account) on 2026-10-29: a re-run of the test done a different way; it agreed with the earlier result.

Test log (from our notes)

What works

Built from the PyPI source release and driven through the Anthropic provider route against a local stand-in model. Headless web use finished a 10-step task (typed into a text box
scrolled
submitted a form
opened and switched tabs
cleanly refused 'forward' with no history) and returned a success dict. Keyboard down
down
enter picked a dropdown option
a checkbox click took
a page script reading cookies was refused
scrolling at the end reported no effect to the model
scrape-mode misuse was refused and the run stopped after 3 bad turns with status incomplete. Two parallel web tasks returned '2/2 tasks succeeded'. Shell write
replace
grep and glob worked
and a wrong replace failed with a clear mismatch message. With Chrome hidden it raised 'no browser found: install Google Chrome to use web mode'. With the network cut except the stand-in, AutoCua only contacted the model API.

What breaks

Confirmed from the first run: shell use returns the bare string 'Exit' instead of the response dict its docstring promises (also on the Anthropic route)
and the agent's own next-goal text shows up inside the page outline on every next step. New: typing into a native dropdown fails with 'the field did not take focus
nothing typed: focus is on select'
and clicking the dropdown marks it expanded but its options never appear in the page outline
although the click tool docs say they will. The shell agent's file tools are not limited to the per-run workspace folder (see security). Building the source release needs Rust 1.88 or newer
older Rust fails on a dependency. Linux shell use still needs system introspection packages pip can't install.

Quality score

3/5 — our hands-on rating on a 1–5 scale, scored by the published rubric.

Confirms partial 3/5: web use is solid with clear errors and parallel tasks work, but shell use drops its result, native dropdowns need a keyboard workaround, and shell file tools aren't confined to the workspace.

Among tested tools in category group “”. Ties share a score; tied tools are listed in no particular order.
