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 | $0.00159 | $0.04283 |
| Opus 5 | $0.00079 | $0.02142 |
| Sonnet 5 | $0.00032 | $0.00857 |
| Haiku 4.5 | $0.00016 | $0.00428 |
Grade A, and why
limrun-xcode 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 3d 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 — 404 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remote Xcode build
Build Apple projects on Limrun's remote Xcode, from any environment (Linux,
Windows, macOS, VM, container). lim xcode build syncs your sources to a remote
Xcode instance, builds there, and (when a simulator is attached) installs and
relaunches the app. Never fall back to local Xcode, local simulators, or local
build tools. Your job doesn't end at a green build: get the app running, verify
it works, and iterate until the user is satisfied.
For driving the app once it's running (tap, type, element tree, screenshot,
record), use the limrun-ios-simulator skill. For Bazel workspaces, use
limrun-xcode-bazel instead of this skill.
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 --help instead of guessing:
lim xcode --help
lim xcode build --help
Build
Instead of xcodebuild, build with:
lim xcode build .
This creates or reuses the remembered Xcode target, syncs the current directory, and streams the build logs through stdout and stderr.
Use --scheme and --workspace if the project has multiple schemes or uses a
workspace file:
lim xcode build . --scheme MyApp --workspace MyApp.xcworkspace
Use --configuration Debug or --configuration Release for a specific Xcode
configuration. If omitted, Limrun uses limbuild's project-type default: Debug
for native Xcode builds, Release for React Native / Expo builds.
lim xcode build . --configuration Debug
--dev-server-url is only supported with --configuration Debug for React
Native / Expo builds. It's a post-install launch URL: limbuild validates it is a
parseable absolute URL, then opens it unchanged after installing on the attached
simulator. Framework-specific skills construct the correct URL.
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-xcode is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed yesterday), licensed MIT. It adds 159 tokens to every session and 4,283 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.
