A workflow for controlling an iOS Simulator, a computer-based copy of an iPhone or iPad used for testing apps. It takes UI snapshots, acts on identified elements, and checks the result with another snapshot or screenshot.

Use it to navigate simulator apps, tap controls, type text, inspect accessibility elements, and verify screen layouts.

It reduces mistakes caused by tapping outdated or guessed screen coordinates. Rechecking the interface after each action shows whether the app actually changed as expected.

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	$0.00141	$0.01373
Opus 5.5	$0.00056	$0.00549
Sonnet 5.5	$0.00028	$0.00275
Haiku 4.5	$0.00014	$0.00137

Security

Grade A, and why

agent-ios 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 1mo 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.

agent-ios: drive the iOS Simulator

agent-ios gives you the agent-browser workflow for the iOS Simulator: snapshot the UI to get element refs, act on refs, verify with another snapshot or a screenshot.

The loop

agent-ios snapshot -i        # 1. see the screen: elements with @refs
agent-ios tap @e3            # 2. act on a ref
agent-ios snapshot -i        # 3. re-snapshot: the UI changed, refs are new
agent-ios screenshot         # 4. visual check when layout/rendering matters

Rules:

Always snapshot before acting. Refs belong to one snapshot generation; acting on refs from before a UI change exits with code 3 ("take a new snapshot").
Re-snapshot after anything that changes the screen - taps, navigation, typing, alerts.
Prefer @refs over raw coordinates. Fall back to tap x y only when an element is missing from the tree (some React Native views merge children into one accessibility element; find the target visually via screenshot and tap its coordinates in points).
Verify, don't assume. After an action, confirm the effect with snapshot (structure) or screenshot (pixels; the printed path is a PNG you can read).

Reading snapshots

snapshot gen=2 app=host.exp.Exponent screen=402x874
@e11 TextField ph="Search Credentials" (117,89 252x17) [disabled]
@e12 Other "Add Credential" (24,236 354x89)

Format: @ref Type "label" id=identifier val="value" ph="placeholder" (x,y wxh) [flags]
Flags: [disabled] [selected] [focused] [offscreen]. Offscreen refs (closed drawers, scrolled-away rows) refuse to tap - scroll or open the container first.
React Native tappables usually appear as Other with a label, not Button. They tap fine by ref.
snapshot with no -i shows the full tree including static text; -i shows only actionable, on-screen elements. --json gives the structured tree.
A [!] a system alert is present line means springboard has a dialog up - handle it before anything else.
The system share sheet (Save as PDF, Copy, Save to Files, Print, app targets) shows up in the tree and is tappable by ref - its out-of-process coordinates are translated to screen space automatically. If a share action is collapsed under "View More", tap that first.
Some pickers run in a fully separate process and do not appear in the session app's tree at all - most notably the Files "save to" / document picker. snapshot there returns nothing. Drive those from a screenshot with coordinate taps, or snapshot --app com.apple.springboard. Prefer pre-granting access (agent-ios permissions grant photos <bundleId>) so pickers/alerts don't appear mid-flow.

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.
