ios-rocketsim-operator

ios-rocketsim-operator is a skill for Claude Code, Codex from Xopoko/build-swift-apps. It costs 31 tokens per session (566 once invoked), scanned A, original, MIT.

A skill for inspecting and controlling an iOS Simulator through RocketSim, a macOS app for automating simulated Apple devices. It covers accessibility state, gestures, typing, hardware buttons, and command-line automation.

In plain words
What is it for?
Use it to inspect simulator state, perform taps and other gestures, enter text, press simulated hardware buttons, and automate simulator actions from the command line.
Why use it?
It lets an agent interact with a simulated iPhone or iPad and verify interface behavior without relying only on manual testing. It also checks that the correct RocketSim installation and macOS tools are available.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ios-rocketsim-operator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

iOS RocketSim Operator

Before invoking Apple-only binaries, confirm the execution context is macOS. From Windows or Linux, run those steps in a Mac SSH project or through an already configured remote transport; do not retry missing Apple binaries locally.

Use the installed RocketSim app as the versioned Simulator automation layer. Always resolve the matching app bundle, bundled skill, and CLI before interacting with a simulator.

Discovery

Prefer a running RocketSim bundle:

ROCKETSIM_PID="$(pgrep -x RocketSim | head -1)"
APP_PATH=""
if [ -n "$ROCKETSIM_PID" ]; then
  APP_PATH="$(ps -o command= -p "$ROCKETSIM_PID" | sed 's#/Contents/MacOS/RocketSim$##')"
fi
printf '%s\n' "$APP_PATH"

If not running, enumerate candidates with:

mdfind "kMDItemCFBundleIdentifier == 'com.swiftLee.RocketSim'"

Also check /Applications/RocketSim.app, /Applications/RocketSim 2.app, ~/Applications/RocketSim.app, and ~/Applications/RocketSim 2.app.

For each candidate, validate both files:

test -f "$APP_PATH/Contents/Resources/Agent-Skill/SKILL.md" && \
test -x "$APP_PATH/Contents/Helpers/rocketsim"

Use the first valid candidate. If RocketSim is running, use the running bundle only if it validates; otherwise rediscover or stop.

If no candidate validates, tell the user to launch or install a current RocketSim build from the Mac App Store: https://apps.apple.com/us/app/rocketsim-for-xcode-simulator/id1504940162

Required Paths

After discovery, set:

  • Bundled skill: $APP_PATH/Contents/Resources/Agent-Skill/SKILL.md
  • CLI: $APP_PATH/Contents/Helpers/rocketsim

Before any CLI call:

pgrep -x RocketSim >/dev/null && echo "Running" || echo "Not running"

If RocketSim is not running, ask the user to launch it. If it is running from a different bundle than APP_PATH, restart discovery and prefer the running bundle.

Handoff

Read the bundled Agent-Skill/SKILL.md and follow it. Wherever it refers to rocketsim, use the resolved absolute CLI path. Do not use ad hoc simulator automation until discovery, validation, and the running-app check pass.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
