The Agent Skills Directory

[COMMAND_EXECUTION]: The skill includes instructions for the agent to use shell commands (ls) to enumerate files in platform-specific skill directories (e.g., ~/.claude/skills/, ~/.agent/skills/). This is used solely for a 'companion check' to identify if recommended sibling skills are installed and to offer their installation via the platform's CLI.
[EXTERNAL_DOWNLOADS]: The skill provides numerous examples for installing standard, well-known mobile development tools and SDKs (including appium, detox, firebase-tools, and awscli) from official package registries like NPM and PyPI, as well as Homebrew for macOS utilities.
[COMMAND_EXECUTION]: The skill provides valid shell templates for interacting with cloud service CLIs (AWS, Google Cloud/Firebase) and mobile testing runners (Detox, Appium, WebdriverIO). These are standard engineering workflows for mobile automation.
