debug-app
microsoft/power-platform-skills
Use when the user has finished building a mobile app, started it with `npm run dev`, and wants the running app monitored for runtime errors AND silent failures (empty lists, blank screens, swallowed network errors) and fixed autonomously. Accepts a free-text symptom (e.g., `/debug-app "todos not appearing on home screen"`) to drive terminal-log diagnostics — injects temporary console.log statements at data-path boundaries, reads Metro terminal output, and cleans up logs after the root cause is fixed. Otherwise polls the Metro terminal every 5s, classifies errors using an 8-category table, fixes inline or routes to the right skill, verifies each fix from terminal output, and exits after 3 consecutive clean polls. Foreground loop — blocks the conversation while running. Run only after the app is loaded.
