The class: Operates a desktop or mobile GUI, not only a single site API, and checks that the control it used is the one it intended.
- A screenshot or accessibility tree after each action
- An allowlist of apps the task may change
Depot Pick: BrowserStack
When not to use it: Only need Android VMs / multi-OS desktop fleets — Cua; already on AWS and want $0.17/min metered or $250 slots — Device Farm; browser-only CUA — Anchor/Hyperbrowser; Linux desktop — E2B.
Runner-up: AWS Device Farm.

Failure modes this class and job share (7)
- Benchmark protocol mismatch: Store assisted-or-not, subset, and harness version beside every cited score. Refuse a ranking that mixes those fields.
- Collateral side effects: Snapshot the workspace or app state, then diff it against an allowlist. A passing check plus an unexpected diff is a failure.
- Confirmation skip: Gate those tool names on an approval id recorded before the call. A missing approval is a failure even if the downstream tool returns success.
- GUI grounding miss: After each GUI action, compare the resulting screen or accessibility tree to the control the plan named. Stop when they differ.
- Partial tool success: Require a per-item status and a failure count. Success for the task requires the failed count to be zero or explicitly handed to a retry queue.
- Prompt injection: Compare each tool call to the original user task. If the call only makes sense given text that arrived from a fetched page, file, or message, stop and ask. Record which source the instruction came from. This catalog does not store payloads or attack steps.
- Tool loop: Hash the last several tool names and arguments. Stop when the same call repeats and the observation did not change. Cap tool calls per task.
