Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00160 | $0.03596 |
| Opus 5 | $0.00080 | $0.01798 |
| Sonnet 5 | $0.00032 | $0.00719 |
| Haiku 4.5 | $0.00016 | $0.00360 |
Grade A, and why
limrun-ios-simulator 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 2d 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 — 355 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Limrun iOS Simulator
Interact with an app running on a Limrun cloud iOS simulator, from any
environment (Linux, Windows, macOS, VM, container). This skill is build-agnostic:
it assumes the app was already built and installed by a build skill
(limrun-xcode-bazel for Bazel, limrun-xcode for xcodebuild). Keep build
concerns in those skills; this one is about driving the running simulator.
Never use local Xcode, local simulators, or local macOS tools.
Auth and CLI
Install if needed: npm install --global lim. Auth is lim login or
LIM_API_KEY (it may be set outside the project, so don't ask for it just
because it's missing from .env or the shell). The CLI is the source of truth:
the commands in this skill are verified, but if a flag errors or you need one
not shown here, check lim ios <subcommand> --help instead of guessing.
Installing an app bundle
You can either use Limrun remote Bazel or Xcode services to build the app bundle and have
it installed to the simulator automatically or you can sync a pre-built local .ipa
file or .app folder to the simulator. The main requirement is that it must be
built for simulator.
Build and install
A build skill usually attaches the simulator for you (lim xcode rbe --ios, or
lim xcode build . then attach). Check what's already there:
lim xcode get # is a simulator attached to the current build target?
lim ios list # all running iOS instances
If none is attached, create one. It installs the last build immediately, so you don't need to rebuild:
lim ios create --attach
If the create (or lim xcode rbe --ios) output includes a signed stream URL,
share it with the user as a Markdown link, like
[Live simulator](<signed-stream-url>). If you have a browser the user can see,
open the URL there and tell them. Otherwise pass --no-open to create: it
skips opening the URL locally and still prints it for sharing.
lim xcode get prints a Limrun console URL instead. It opens the same live
view but requires a console login, so prefer the signed stream URL for sharing.
If the console URL is all you have, share it and mention it needs login.
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.

limrun-ios-simulator is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed yesterday), licensed MIT. It adds 160 tokens to every session and 3,596 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
