Diagnoses and fixes runtime bugs in Capacitor iOS/Android apps - white/blank screen on launch, startup crashes, `"X" plugin is not implemented on ios/android`, `net::ERR_CLEARTEXT_NOT_PERMITTED`, App Transport Security blocks, CORS on capacitor://localhost, permission denials, live reload not connecting, and Capacitor 8.5+ UIScene regressions (appUrlOpen, universal links, pause/resume silent because AppDelegate callbacks stopped). Covers Safari Web Inspector, chrome://inspect, Xcode/LLDB…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Debugging Capacitor Apps Find which layer is broken (web, bridge, native, OS config), prove it with the right inspector, then fix the smallest thing. ## When to Use TRIGGER when: - App shows a white/blank screen, crashes on launch, or freezes after a native call. - Error `"<Name>" plugin is not implemented on ios|android` or `"<Name>.<method>()" is not implemented on ...`. - Network calls fail on device only: `net::ERR_CLEARTEXT_NOT_PERMITTED`, ATS "requires the use of a secure connection", CORS errors. - Permission prompts never appear or always deny. - Live reload (`cap run --url`, `server.url`) shows a blank page or "Webpage not available". - After updating to Capacitor 8.5+ / Xcode 27: `appUrlOpen` silent, universal links open the app but do nothing, JS `pause`/`resume` or custom AppDelegate code no longer runs. - User asks "how do I debug / inspect my Capacitor app". Do not use: - Only need to stream, filter, or save logs or crash reports -> `ios-android-logs`. - Performing the AppDelegate -> SceneDelegate migration itself -> `capacitor-uiscene-migration`. - Setting up deep links, AASA, assetlinks from scratch -> `capacitor-deep-linking`. …

How to install
mdr add cap-go/capgo-skills/debugging-capacitor@sha256:cb47111216db4c04The line at the top of this page pins the label git:20261011.86834d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
