About this skill

“iOS Simulator control from inside Orca, with the live device view in Orca's emulator pane. Use when driving a booted Apple Simulator on macOS: taps, gestures, typing, hardware buttons, rotation, and the accessibility tree, or when an iOS change needs simulator evidence. For an Android device or emulator use the Android emulator skill; build and install the app with xcodebuild or simctl first.”

— description from SKILL.md by stablyai

Orca iOS Simulator Control is a skill in stablyai/orca (88k stars). Its SKILL.md is about 584 tokens, and copies of it appear in 1 other owners' repositories. Licence: Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit cbad641. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Orca iOS Simulator Control loads about 584 tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 272 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~584

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Orca Emulator

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.

Resolve the CLI for this session

Choose the executable once and reuse it for every later command:

  • If the ORCA_CLI_COMMAND environment variable is set, use its value. Orca exports this for managed WSL sessions.
  • Otherwise, in a dev checkout whose session exposes ORCA_DEV_REPO_ROOT, use orca-dev.
  • Otherwise, on Linux outside an Orca-managed terminal, use orca-ide. Never run bare orca 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.
  • Otherwise, use 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.

Load the version-matched guide before running Orca commands

text
ORCA 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 it fails with runtime_access_denied, your sandbox blocked the connection: re-run it with escalated permissions, and do not run ORCA open or restart Orca. If skills get is unknown, explain that updating Orca restores the guide; use --help for read-only discovery and do not guess unsupported commands.
