One tool for any single real phone action. Jev first picks which ONE atomic kind this goal wants -- open an app, tap, long-press, type, swipe, scroll-to-find, press a key, toggle a service, set DND, take a screenshot, or read a system service (the same ACTION_KINDS the CLI toolkit uses) -- then runs exactly that one real action and returns its result. include_screenshot=True also attaches a real screenshot of the resulting screen -- off by default since an image costs real context; ask for one at a checkpoint, not after every single step in a sequence. Never plans or chains more than one action; sequencing multiple goals is still the calling agent's job.

Take a screenshot of the current screen and return the actual image -- never gated (read-only), no goal needed, no candidates to narrow.

Resolve a pending action from any device_* tool. decision is "approve" or "deny". An optional command overrides the proposed command (e.g. a human-corrected variant), matching PLAN.md's device_approve(thread_id, decision, command?) signature. include_screenshot=True attaches a real screenshot, same off-by-default tradeoff as device_do.
