What is ios-simulator-skill?

A collection of scripts for building, testing, and automating iOS apps in the iOS Simulator, which is Apple's virtual iPhone and iPad environment. It uses accessibility information to find and operate interface elements.

Checking the simulator, launching apps, mapping screens, tapping controls, entering text, running accessibility checks, and taking screenshots for visual verification.

It helps agents test apps with named controls and structured screen data instead of relying mainly on fragile pixel coordinates.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.02657
Opus 5	$0.00023	$0.01328
Sonnet 5	$0.00009	$0.00531
Haiku 4.5	$0.00005	$0.00266

Security

Grade A, and why

ios-simulator-skill 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 7d ago.

The scan reads SKILL.md. This mod also ships 35 executable files (scripts/accessibility_audit.py, scripts/app_launcher.py, scripts/app_state_capture.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.

iOS Simulator Skill

Build, test, and automate iOS applications using accessibility-driven navigation and structured data instead of pixel coordinates.

Quick Start

# 1. Check environment
bash scripts/sim_health_check.sh

# 2. Launch app
python scripts/app_launcher.py --launch com.example.app

# 3. Map screen to see elements
python scripts/screen_mapper.py

# 4. Tap button
python scripts/navigator.py --find-text "Login" --tap

# 5. Enter text
python scripts/navigator.py --find-type TextField --enter-text "[email protected]"

All scripts support --help for detailed options and --json for machine-readable output.

Always prefer the accessibility tree over screenshots for navigation. The accessibility tree gives you element types, labels, frames, and tap targets — structured data that's cheaper and more reliable than image analysis.

Use this priority:

screen_mapper.py → structured element list (5-7 lines, ~10 tokens)
navigator.py --find-text/--find-type/--find-id → semantic interaction
Screenshots → only for visual verification, bug reports, or visual diff

Screenshots cost 1,600–6,300 tokens depending on size. The accessibility tree costs 10–50 tokens in default mode.

Changes

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.
