Device Interaction

TRIGGER when: user asks to verify/test/check if the app works on device, after implementing a UI-affecting feature that needs device verification, user says "does it work", "test this", "check on device", user reports UI doesn't work as expected, need to debug touch/interaction issues. DO NOT TRIGGER when: user asks about unit tests only, build-only requests without device testing, code review without device testing, simulator configuration questions, changes that don't affect UI (e.g. comments, refactors, non-UI logic).

For the Main Agent

This is a SUBAGENT skill. Invoke it via the Agent tool when device verification is needed.

Agent tool:
- subagent_type: "general-purpose"
- description: "Verify login feature works"
- prompt: "Using the device-interaction skill, verify that the login feature works correctly on session <device-interaction-session>. Launch the app, capture screenshot and UI hierarchy, check that the login button is visible and tappable, and report if the implementation is working correctly."

After implementing a UI-affecting feature, invoke this skill to verify the implementation works on a device.
