emumanager

emumanager is a skill for Claude Code, Codex from ithinkihaveacat/dotfiles. It costs 84 tokens per session (1,725 once invoked), scanned A, original, Apache-2.0.

A manager for Android SDK components, system images, emulators, and Android Virtual Devices. An emulator is a computer-made Android device used to run and test apps; an AVD is its saved device configuration.

In plain words
What is it for?
Use it to install or resolve emulator system images, create and start AVDs, stop emulators, diagnose SDK setup, and wait for a device to finish booting.
Why use it?
It brings common Android device setup and startup tasks into one workflow and checks whether the SDK environment is ready. It also handles different device types such as phones, watches, TVs, and cars.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

emumanager scanned grade A with 1 finding 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 7d 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.

Android Emulator Manager

Using the Manager Script vs. Raw SDK Tools

Use scripts/emumanager as the primary interface for managing Android emulators and AVDs. References to scripts/... in this skill are relative to this skill directory. The script unifies and orchestrates sdkmanager, avdmanager, and emulator:

  • Automatic system image resolution across device form factors (--mobile, --wear, --tv)
  • Boot completion detection with configurable timeouts
  • Preflight SDK environment diagnostics (scripts/emumanager doctor)
  • Sensible hardware defaults and clear error diagnostics

When to use raw SDK tools: If you need specialized emulator launch flags or are debugging an isolated SDK installation issue, calling emulator or avdmanager directly is supported. Consult the script source in scripts/ to see the precise command invocations and environment checks it performs.

Quick Start

Environment Variables

export ANDROID_HOME="${ANDROID_HOME:-$HOME/.local/share/android-sdk}"
export ANDROID_USER_HOME="${ANDROID_USER_HOME:-$HOME/.android}"

Prerequisites

  • Java 17 or higher
  • Hardware acceleration: KVM on Linux, HVF (Hypervisor Framework) on macOS
  • Network access for downloading SDK components

Highest-Value Commands

# First-time setup (installs cmdline-tools, platform-tools, build-tools, emulator)
scripts/emumanager bootstrap

# Diagnose issues (Java version, hardware acceleration, disk space)
scripts/emumanager doctor

# Create a mobile/phone AVD with latest API
scripts/emumanager create avd my_phone --mobile

# Start the AVD
scripts/emumanager start avd my_phone

# List all AVDs (shows running status)
scripts/emumanager list avd

# Show detailed AVD information
scripts/emumanager info avd my_phone

Subcommand Overview

bootstrap

Set up SDK environment. Installs cmdline-tools, platform-tools, build-tools, emulator, and a platform.

scripts/emumanager bootstrap
scripts/emumanager bootstrap --no-emulator  # Skip emulator installation

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.
