limrun-xcode-bazel

limrun-xcode-bazel is a skill for Claude Code from sutchan/Agent-Skills-Hub. It costs 149 tokens per session (1,906 once invoked), scanned A, original, MIT.

A remote build setup for Bazel-based iOS, macOS, and other Apple apps. It runs the build on Limrun's Mac workers, so the project does not need a local Mac or Xcode.

In plain words
What is it for?
Use it to configure remote Bazel builds for Apple targets and run those builds through Limrun's remote execution service.
Why use it?
It lets developers build Apple software from Linux, Windows, virtual machines, or containers. This removes the need to maintain local Apple build tools.

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.

Security

Grade A, and why

limrun-xcode-bazel 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 4d 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bazel iOS builds on Limrun RBE

Build Bazel Apple projects on Limrun's remote Mac workers — from any environment (Linux, Windows, macOS, VM, container), no local Xcode. lim xcode rbe brings up a remote RBE stack, tunnels it to a local port, and writes a .limrun/ config so bazelisk build --config=limrun runs Apple actions remotely. Never fall back to local Xcode or build tools.

Auth and CLI

Install if needed: npm install --global lim. Auth is lim login or LIM_API_KEY (may be set outside the project — don't ask for it just because it's absent). 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 xcode rbe --help instead of guessing.

Build

  1. From the Bazel workspace root (has MODULE.bazel / WORKSPACE), run lim xcode rbe. It sets up the instance + .limrun/ config and prints the exact build command. The tunnel runs in the background (prints a PID); --no-daemon keeps it foreground.
  2. Run the printed command, e.g. bazelisk --digest_function=sha256 build --config=limrun //App.

Don't hand-write .limrun/ or the flags — the CLI generates them for the fleet's Xcode and your OS. Re-run lim xcode rbe (after --stop) to refresh after a fleet Xcode upgrade.

To add your own Bazel flags to the limrun path without editing the generated config, put them in user.limrun.bazelrc at the workspace root. The generated config try-imports it last, so your build:limrun --… lines win, and it survives lim xcode rbe regeneration (.limrun/ does not).

Run on a simulator

lim xcode rbe is build-only; attach a simulator when the user wants to see or run the app. Check or attach (it installs the last build immediately, so no rebuild is needed):

lim xcode get             # is a simulator already attached?
lim ios create --attach   # attach one

Add --no-open when you have no browser to show the user; it skips opening the stream URL locally and still prints it for sharing.

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.

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.
