PhoneHarness Benchmarks Mobile Agents Across GUI, CLI, and Tool Actions

June 11, 2026

PhoneHarness is an execution harness and benchmark for phone-use agents that combines GUI control, device-side CLI commands, and structured tool calls in verifiable mobile workflows. It uses deterministic action routing with bounded GUI delegation and auditable side-effect verification, moving beyond screen-tap prediction to end-to-end task completion.

HOW THIS AFFECTS YOU

●

builderIf you're building mobile agents, PhoneHarness provides a verifiable evaluation harness that tests real workflow completion across action types — more representative than GUI-only benchmarks.

●

researcherThe mixed-action MDP with auditable side effects is a cleaner evaluation setup for studying when agents should switch between GUI, CLI, and tool modalities.
