debug-issue

Use this skill when the user asks to debug, investigate, inspect for bugs, fix an issue, or says the app is broken, failing, wrong, blank, errored, or not working. Also use it when you observe a concrete existing failure yourself, including runtime errors, failed tool/API calls, browser console errors, app errors, app logs, actual visual regressions, failing lint/tests/builds, deployment issues, bad data, auth issues, or flaky behavior. Do not use this skill for forward-looking UX polish requests like "make the UX nicer" or "improve the design" unless the user identifies a specific existing broken behavior or regression to verify.
