Drive a native macOS app via the cua-driver CLI (default) or MCP server — snapshot its AX tree, click/type/scroll by element_index, verify via re-snapshot. Use when the user asks you to operate, drive, automate, or perform a GUI task in a real macOS application on the host (e.g. "open a file in TextEdit", "navigate to /Applications in Finder", "click the Save button in Numbers").
Firefox browser automation for AI agents using Playwright. Use when the user needs Firefox-specific browser automation, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or any task requiring Firefox. Triggers include requests to "use Firefox", "open in Firefox", "test in Firefox", "automate Firefox", or any browser task where Firefox is specified or preferred.

Use when executing an implementation plan fully autonomously without human interaction
Use when validating UI changes end-to-end before claiming work is complete — spawns a fresh server pair from the worktree and runs Playwright tests against it
