Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00129 | $0.04531 |
| Opus 5 | $0.00064 | $0.02266 |
| Sonnet 5 | $0.00026 | $0.00906 |
| Haiku 4.5 | $0.00013 | $0.00453 |
Grade B, and why
generating-store-screenshots scanned grade B with 1 finding 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 6d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
If Xcode is missing: "Xcode is not installed. Install it from the Mac App Store, then run `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer`." How it starts
The opening of the file, as written. The whole thing — 439 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generating Store Screenshots
Simulator mode — ask the user first
Before checking prerequisites, detect what is already running and ask:
# iOS — what's booted?
xcrun simctl list devices booted 2>/dev/null
# Android — what's connected?
adb devices 2>/dev/null
Then ask:
"I found [device name] booted. Which screenshot mode do you want?
- Lightweight (recommended) — use only this simulator. Faster, no extra installs. One device size per platform.
- Full — capture all required device sizes (iPhone 6.9", 6.5", iPad 13" for iOS). Requires installing additional simulators.
Default: Lightweight."
Lightweight mode behavior:
- iOS: use the single booted simulator. Detect its resolution with
xcrun simctl list devices booted --jsonand name the output folder accordingly (e.g.,iPhone-15-Pro-2556x1179if that's what's running). This is valid for App Store submission — Apple accepts any supported device size. - Android: use the connected emulator. Name the folder by its reported resolution.
- No need to install additional simulators.
Full mode behavior:
- Requires installing iPhone 16 Pro Max (1320×2868, mandatory from 2026), iPhone 11 Pro Max (1242×2688), and iPad Pro 13" (2064×2752) simulators.
- Run each capture loop per device, per locale.
Prerequisites — check BEFORE starting
Run each detection command. If any check fails, stop and tell the user exactly what is missing.
Xcode (iOS only)
xcode-select -p # must return a valid path, e.g. /Applications/Xcode.app/Contents/Developer
xcodebuild -version # must show Xcode 15+ for iPhone 16 Pro Max simulator
xcrun simctl list devices available | grep -E "iPhone|iPad" # must list at least one device
If Xcode is missing: "Xcode is not installed. Install it from the Mac App Store, then run sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer."
Android Studio + SDK (Android only)
adb --version # must return a version string
echo $ANDROID_HOME # must be set, e.g. /Users/you/Library/Android/sdk
emulator -list-avds # must list at least one AVD (virtual device)
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

generating-store-screenshots is a skill published in the GitHub repository ofcskn/mobile-automation-plugin (2 stars, last pushed 2mo ago), licensed MIT. It adds 129 tokens to every session and 4,531 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
