Measured on the bot's own box (8 tasks x 2, grok-4.7): 14/16 done, 120 steps, 1114 s before;
16/16, 102 steps, 574 s after (model time 1015 -> 471 s). A replayed skill: 49 s -> 15 s.
Knowing the machine
- facts.rs: 電腦現況 per computer (system, desktop, systemd, sudo, network, package manager,
tools, apps, a fixed TZ), read once by a small read-only probe, kept 30 min, in the
instructions at the start of a turn.
- The box's sudo is the bot's: only what follows sudo is checked against the always-denied
list (it was refused outright, while the instructions said it could sudo), and commands with
sudo run as the box's root (setuid does nothing under gVisor).
- Box image v8 drops ENV TZ=UTC (it overrode /etc/localtime). ANYBOT_BOX_IMAGE /
ANYBOT_BOX_VOLUME give a throwaway box its own image and volume, never adopting the real one.
- Mac shell sandbox: App Store app CLIs (they carry their own app sandbox) and ps/top run
outside it; plain `osascript -e` too, asked the first time even in direct mode, refusing do
shell script, terminals, keystrokes, file reads, ObjC and the secret folders. A command the
sandbox broke says so, instead of looking like a broken program.
Reaching what it sees
- The Mac menu bar's status icons are numbered (each app's AXExtrasMenuBar, named from inside
for the system's own), computer_use_zoom looks closer at full sharpness.
- Numbers stay with their controls from look to look (they were reassigned every look, so a
step's second click landed elsewhere); the box's front window is listed first; a control can
be named instead of numbered (name "4").
- Web page numbering walks open shadow DOM (Chromium settings, web components).
- A box on a Docker host elsewhere retries the next port when the usual one is taken (a retry
without it came up with no network).
Working like a person
- Instructions: pick the route, know what done looks like, one route, check once, say what's
stuck instead of faking it with a substitute, ask before cutting the connection.
- StepPlan: the bot's model takes the first step, the step after trouble (failed, refused,
repeated, nothing changed on screen, the quick model switching routes), one in four, and the
final check; a quick model (Bot.step_model, auto: grok-4.20-0309-non-reasoning on xAI) does
the planned steps in between, falling back to the bot's model if it can't be used.
- Skills keep the steps that worked (with what each acted on, not numbers); replay_skill does
them again with no model in between, finding each control again, handing back on a mismatch.
