Get Started Free →Control a mobile (iOS) emulator / simulator stream from inside Orca using the `orca` CLI. Use for taps, gestures, typing, hardware buttons, camera injection, permissions, accessibility tree, and more — all while seeing the live view in Orca's emulator pane. Prefer this over raw `npx serve-sim` or direct simctl when running agents inside Orca (the orca surface handles device scoping, helper lifecycle, and worktree context). Complements the orca-cli skill for terminals, worktrees, and the built-in

This discovery stub loads the version-matched guide from the Orca executable used for this session.
Prefer Orca over raw serve-sim or direct simctl for simulator control inside Orca; it handles device scoping, helper lifecycle, and worktree context.
Choose the executable once and reuse it for every later command:
ORCA_CLI_COMMAND environment variable is set, use its value. Orca exports thisfor managed WSL sessions.
ORCA_DEV_REPO_ROOT, use orca-dev.orca-ide. Never run bareorca there — outside Orca's terminals it normally resolves to the GNOME Orca screen reader (/usr/bin/orca) and starts speech on the user's machine.
orca.Below, ORCA is a placeholder for the executable you resolved. Substitute it before running anything; do not create a shell variable or run ORCA literally. This works the same way in POSIX shells, PowerShell, and cmd.exe.
If the selected executable cannot run, report its exact error and stop. Do not fall through to another executable, which could silently target a different Orca build.
textORCA skills get orca-emulator
Prefer --json. Use the selected executable's --help for commands or flags the guide does not cover. If a command reports that Orca is not running, start it with ORCA open --json and retry. If skills get is unknown, explain that updating Orca restores the guide; use --help for read-only discovery and do not guess unsupported commands.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted, and 20 counted toward the lift figure. The other 3 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +57 percentage points is the difference between those two pass rates over the 20 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
| Model | Method | Date | Lift |
