DevTool Skill

This skill allows you to interact with Lynx applications running on connected devices (Android, iOS, Desktop) using the Lynx DevTool CLI.

Usage

The CLI is located at <path_to_the_skill>/scripts/index.mjs relative to this skill's directory. You can run it using node.

In the skill directory, use:

node <path_to_the_skill>/scripts/index.mjs <command>

Note: All command outputs are multi-line JSON. You can use jq or Node.js to process the data.
