INVOKES: `maui devflow`, `dotnet`, `adb`, `simctl`.\n---\n\n# DevFlow Debug\n\nUse this skill for the active debugging loop after a MAUI app has DevFlow\npackages and `builder.AddMauiDevFlowAgent()` registered.\n\n## When to Use\n\n- Build and run a MAUI app on Android, iOS, Mac Catalyst, macOS, Windows, or GTK.\n- Choose or create a simulator\u002Femulator for a project.\n- Wait for a DevFlow agent, inspect the visual tree, tap\u002Ffill UI, or capture screenshots.\n- Recover from DevFlow connection failures after the app is integrated, including broker, port, and Android adb forwarding issues.\n- Debug Blazor Hybrid content through DevFlow WebView\u002FCDP commands.\n- Read app logs, network captures, preferences, device info, or recordings through DevFlow.\n- Iterate on an app bug with a build -> deploy -> inspect -> fix loop.\n\n## Route Elsewhere\n\n- If DevFlow packages or `MauiProgram.cs` registration are missing, use `maui-devflow-onboard`.\n- If the failure is a generic build or SDK issue with no DevFlow angle, use normal .NET\u002FMAUI diagnostics.\n\n## Optional Session Feedback Nudge\n\nIf you have retried the same MAUI DevFlow workflow several times, tried multiple\nworkarounds, or are ending a long DevFlow-assisted debugging session, ask\nwhether the user wants to run `maui-devflow-session-review` to summarize friction\nfor MAUI DevFlow product feedback. Do not run it automatically.\n\n## Core Loop\n\n1. Confirm the app is already integrated:\n\n   ```bash\n   grep -rl \"Microsoft.Maui.DevFlow\" --include=\"*.csproj\" .\n   ```\n\n   If no project has DevFlow package references, stop and switch to `maui-devflow-onboard`.\n\n2. Pick the target framework and launch target. Do not assume `net10.0`; inspect the project first.\n\n   ```bash\n   grep -i \"TargetFramework\" *.csproj Directory.Build.props 2>\u002Fdev\u002Fnull\n   ```\n\n3. Start or select the device\u002Femulator. For Android and iOS, avoid reusing a simulator\u002Femulator that is already running another app under investigation.\n\n4. Launch the app and keep the launch process alive when required.\n\n   - iOS, Android, and Mac Catalyst `dotnet build -t:Run` usually block for the app lifetime.\n   - GTK `dotnet run` blocks for the app lifetime.\n   - macOS AppKit builds can exit after compiling; launch the `.app` separately.\n\n5. Wait for the DevFlow agent before inspecting UI:\n\n   ```bash\n   maui devflow wait\n   maui devflow agent status\n   maui devflow ui tree --depth 3 --fields \"id,type,text,automationId\"\n   ```\n\n   Treat `agent status` as the runtime truth for reachability and app identity.\n   `diagnose` is broader environment state; it can report broker\u002Fproject details\n   without proving the current app is reachable.\n\n   If `wait`, `list`, or `ui tree` cannot connect after the app is running, load `references\u002Fconnectivity.md` and recover the broker\u002Fagent connection before continuing.\n\n6. Prefer AutomationId-first validation for UI flows:\n\n   ```bash\n   maui devflow ui query --automationId save-button\n   maui devflow ui tap \u003Celement-id-from-query>\n   ```\n\n   If important controls do not have stable `AutomationId`s, add them before\n   relying on text, coordinates, screenshots, or brittle tree positions.\n\n7. Inspect, interact, capture evidence, then edit the app and repeat from launch.\n\n## Critical Anti-patterns\n\n- Do not treat an empty `maui devflow list` as proof the project is not integrated. `list` is runtime state; project files are source of truth.\n- Do not use arbitrary sleeps after launch. Use `maui devflow wait` to gate on the actual agent connection.\n- Do not kill an async `dotnet build -t:Run` or `dotnet run` shell while you still need the app; that often kills the app.\n- Do not reuse a busy simulator\u002Femulator when multiple MAUI apps or agents may be running.\n- Do not debug Blazor WebView DOM issues through the native visual tree alone; use the WebView\u002FCDP commands.\n- Do not drive key app flows by coordinates when AutomationIds are available or can be added.\n\n## Stop Signals\n\n- Stop and switch to `maui-devflow-onboard` when package references or `AddMauiDevFlowAgent()` are absent.\n- Stop and ask which project, device, or agent to target when multiple candidates match.\n- Stop rebuilding after two identical failures until you inspect the first meaningful build\u002Fruntime error.\n- Stop using screenshots for exact property values; query the visual tree or properties instead.\n\n## Reference Map\n\nLoad these only when needed:\n\n- `references\u002Fsetup.md` - detailed integration, package, entitlement, and update notes.\n- `references\u002Fconnectivity.md` - broker, agent, port, Android forwarding, and \"no agents connected\" recovery.\n- `references\u002Fandroid.md` - Android SDK, emulator, adb, build, deploy, and port forwarding details.\n- `references\u002Fios-and-mac.md` - iOS simulator, Mac Catalyst, permissions, entitlements, and Apple tooling.\n- `references\u002Fmacos.md` - macOS AppKit project shape, launch model, and troubleshooting.\n- `references\u002Flinux.md` - GTK\u002FLinux launch, packages, and WebKitGTK notes.\n- `references\u002Fbatch.md` - batching multiple DevFlow UI\u002FWebView operations.\n- `references\u002Ftroubleshooting.md` - build, connection, CDP, and platform-specific failure recovery.\n",{"data":47,"body":48},{"name":4,"description":6},{"type":49,"children":50},"root",[51,60,75,82,122,128,157,163,176,182,655,661,731,737,775,781,786,876],{"type":52,"tag":53,"props":54,"children":56},"element","h1",{"id":55},"devflow-debug",[57],{"type":58,"value":59},"text","DevFlow Debug",{"type":52,"tag":61,"props":62,"children":63},"p",{},[64,66,73],{"type":58,"value":65},"Use this skill for the active debugging loop after a MAUI app has DevFlow\npackages and ",{"type":52,"tag":67,"props":68,"children":70},"code",{"className":69},[],[71],{"type":58,"value":72},"builder.AddMauiDevFlowAgent()",{"type":58,"value":74}," registered.",{"type":52,"tag":76,"props":77,"children":79},"h2",{"id":78},"when-to-use",[80],{"type":58,"value":81},"When to Use",{"type":52,"tag":83,"props":84,"children":85},"ul",{},[86,92,97,102,107,112,117],{"type":52,"tag":87,"props":88,"children":89},"li",{},[90],{"type":58,"value":91},"Build and run a MAUI app on Android, iOS, Mac Catalyst, macOS, Windows, or GTK.",{"type":52,"tag":87,"props":93,"children":94},{},[95],{"type":58,"value":96},"Choose or create a simulator\u002Femulator for a project.",{"type":52,"tag":87,"props":98,"children":99},{},[100],{"type":58,"value":101},"Wait for a DevFlow agent, inspect the visual tree, tap\u002Ffill UI, or capture screenshots.",{"type":52,"tag":87,"props":103,"children":104},{},[105],{"type":58,"value":106},"Recover from DevFlow connection failures after the app is integrated, including broker, port, and Android adb forwarding issues.",{"type":52,"tag":87,"props":108,"children":109},{},[110],{"type":58,"value":111},"Debug Blazor Hybrid content through DevFlow WebView\u002FCDP commands.",{"type":52,"tag":87,"props":113,"children":114},{},[115],{"type":58,"value":116},"Read app logs, network captures, preferences, device info, or recordings through DevFlow.",{"type":52,"tag":87,"props":118,"children":119},{},[120],{"type":58,"value":121},"Iterate on an app bug with a build -> deploy -> inspect -> fix loop.",{"type":52,"tag":76,"props":123,"children":125},{"id":124},"route-elsewhere",[126],{"type":58,"value":127},"Route Elsewhere",{"type":52,"tag":83,"props":129,"children":130},{},[131,152],{"type":52,"tag":87,"props":132,"children":133},{},[134,136,142,144,150],{"type":58,"value":135},"If DevFlow packages or ",{"type":52,"tag":67,"props":137,"children":139},{"className":138},[],[140],{"type":58,"value":141},"MauiProgram.cs",{"type":58,"value":143}," registration are missing, use ",{"type":52,"tag":67,"props":145,"children":147},{"className":146},[],[148],{"type":58,"value":149},"maui-devflow-onboard",{"type":58,"value":151},".",{"type":52,"tag":87,"props":153,"children":154},{},[155],{"type":58,"value":156},"If the failure is a generic build or SDK issue with no DevFlow angle, use normal .NET\u002FMAUI diagnostics.",{"type":52,"tag":76,"props":158,"children":160},{"id":159},"optional-session-feedback-nudge",[161],{"type":58,"value":162},"Optional Session Feedback Nudge",{"type":52,"tag":61,"props":164,"children":165},{},[166,168,174],{"type":58,"value":167},"If you have retried the same MAUI DevFlow workflow several times, tried multiple\nworkarounds, or are ending a long DevFlow-assisted debugging session, ask\nwhether the user wants to run ",{"type":52,"tag":67,"props":169,"children":171},{"className":170},[],[172],{"type":58,"value":173},"maui-devflow-session-review",{"type":58,"value":175}," to summarize friction\nfor MAUI DevFlow product feedback.
