agent-device-lab

agent-device-lab is a skill for Codex from vincentkoc/dotskills. It costs 39 tokens per session (1,566 once invoked), scanned A, original, MIT.

A procedure for preparing a trusted Mac and a physical Android phone or iPhone for authorised testing. It covers device trust, developer settings, signing, host tools, and a separate iPhone Mirroring mode.

In plain words
What is it for?
Use it to audit or prepare a physical mobile test device, diagnose trust and signing blockers, or prove one authorised device interaction.
Why use it?
It helps distinguish host or device setup problems from application bugs before testing begins.

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

agent-device-lab 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 Device Lab

Purpose

Prepare a Mac and one physical Android or iPhone for an authorized test. This skill owns host readiness and device enrollment. Use the installed upstream agent-device skill or version-matched CLI help for app-driving commands.

When to use

  • Auditing or preparing host tooling for a physical Android phone or iPhone.
  • Diagnosing device trust, Developer Mode, or runner-signing blockers.
  • Setting up iPhone Mirroring or proving one bounded device interaction.

For ordinary app testing on an already prepared target, use the app automation workflow directly. Simulator setup and fleet deployment are separate tasks.

Workflow

  1. Identify the requested mode, host, physical device, app, and observable result. An audit or plan does not authorize installation, enrollment, settings changes, or app interaction. Continue within existing authorization; obtain only any missing authority for the specific change.
  2. Inspect only the selected mode's prerequisites. Mirroring alone needs no ADB, XCTest runner, or agent-device installation. For agent-device, resolve the installed binary and version; follow its help workflow and current installation requirements. Prefer a trusted installed or project-pinned CLI. Installing a skill does not install that CLI; do not silently fetch and execute a mutable @latest package.
  3. Report missing prerequisites before changing them. Limit authorized host preparation to official platform tools and the selected device platform. Device Trust/RSA prompts, passcodes, Developer Mode confirmation, Apple Account, 2FA, and signing-account authentication belong to the owner. Wait at that boundary; never collect their credentials or bypass the prompt.

Android

Use Google's Android SDK Platform Tools. The owner enables USB debugging and approves this host's RSA key on the phone. adb devices -l must identify the intended physical serial in state device; unauthorized, offline, or a missing device is a blocker. A device entry alone does not prove Android has finished booting. Bind subsequent ADB commands with -s <serial> and agent-device with --platform android --serial <serial>.

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.
