ios-device-build-run

ios-device-build-run is a skill for Codex from jeffy-w/AgentSkills. It costs 85 tokens per session (1,889 once invoked), scanned A, original, MIT.

A workflow for building an iOS app, installing it on a real iPhone or iPad, launching it, and reading its build and device logs. It includes a check for the development environment and can select a connected device.

In plain words
What is it for?
Use it to test iOS apps on physical devices, inspect build failures, capture runtime logs, and search recent device or build output.
Why use it?
It brings the separate build, installation, launch, and log-reading steps into one repeatable process, while helping avoid problems caused by an app that is already running.

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

ios-device-build-run 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ios_device_build_run.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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

iOS Device Build Run

Use the bundled script for repeatable real-device build/run/log workflows:

python3 ios-device-build-run/scripts/ios_device_build_run.py <subcommand> [options]

The script stores durable sessions under:

~/.codex/ios-device-build-run/sessions/<timestamp>-<scheme>/

Each session may contain build.raw.log, build.pretty.log, install.log, run.log, device.log, metadata.json, events.jsonl, pids.json, and devicectl JSON outputs.

Workflow

  1. Run doctor if the environment is unknown: 
    python3 ios-device-build-run/scripts/ios_device_build_run.py doctor
  2. Prefer build-run for the normal path: 
    python3 ios-device-build-run/scripts/ios_device_build_run.py build-run
  3. Device auto-selection prefers wired USB devices. If exactly one wired device is connected, it is used automatically; otherwise pass --device <udid-or-name>.
  4. Read logs through the script instead of dumping whole files: 
    python3 ios-device-build-run/scripts/ios_device_build_run.py logs --session latest --file build --tail 200
python3 ios-device-build-run/scripts/ios_device_build_run.py logs --session latest --file device --grep EffectEngine --tail 300
python3 ios-device-build-run/scripts/ios_device_build_run.py logs --session latest --file all --search 'error|fatal|crash' --ignore-case --context 3
  5. Stop background runtime logging when done: 
    python3 ios-device-build-run/scripts/ios_device_build_run.py stop-log --session latest

Subcommands

  • doctor: verify xcodebuild, xcrun, optional idevicesyslog, optional xcbeautify, and connected physical devices.
  • devices: list available physical iOS devices; simulators are excluded.
  • build: build only, create a session, locate the .app, and read CFBundleIdentifier from Info.plist.
  • install: install an existing or latest-session .app onto a physical device.
  • run: launch an already-installed app from a session or explicit --bundle-id.
  • build-run: build, locate app, install, start runtime log stream, then launch.
  • log-stream: start only runtime log capture for a session.
  • logs: filter/search/tail persisted logs.
  • stop-log: terminate the background runtime log process recorded in pids.json.
  • sessions: list recent sessions.

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.

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.
