Diagnose Power Apps mobile install/startup failures, npm run dev errors, missing package entry points, or QR/device-opening problems even before an app is loaded. Inspect locally first; restore locked dependencies or restart Metro only with explicit approval, never upgrade packages or patch host/MSAL source. For a running native app, monitor sanitized project-local Metro logs and diagnose runtime errors or silent failures such as empty lists and blank screens. Supports startup-only diagnosis, symptoms, port/platform filters, bounded monitoring, and non-mutating --no-fix mode. Verify the original symptom, not merely installation or quiet logs.

Startup diagnosis uses the targeted compatibility inspection below instead of
the shared blanket version check; missing dependencies must not prevent diagnosis.
It does not check for updates. Explicit startup repair/restart approval overrides
shared auto-proceed/default-answer guidance.

# Debug App — Monitor & Fix

Monitor the running app through the project-local `.powernative/metro-logs/` files written by `metro.config.js`, detect runtime and bundle errors, and fix them autonomously by editing the affected files (or routing to the right skill when the fix belongs in a domain like Dataverse schema or auth registration). For silent failures, inject temporary `console.log` statements at data-path boundaries, read only newly appended log bytes, then clean the traces after the root cause is fixed. Modeled on the upstream `app-debugger.agent.md` pattern — foreground loop, bounded polling, configurable clean-check/timeout exits, and optional watch-only operation.
