Use when building Android apps with Kotlin, Jetpack Compose, MVVM, Hilt, Room 3 (KSP, SQLiteDriver, Flow/suspend DAOs), and multi-module architecture. Triggers on requests to create Android projects, modules, screens, ViewModels, repositories, or Android architecture questions. Not for iOS, Flutter, React Native, KMP-only shared code without an Android app module, or backend-only APIs with no Android client.
EnglishLoad the most recent save-to-md session log into a fresh session and brief the new agent on where the prior session left off. Use at the start of a new conversation when the user says "hand off", "pick up where we left off", "resume the last session", "continue from yesterday", "load the last session log", or otherwise signals they want the prior session's context restored. Pair with save-to-md — that skill writes the log; this one reads it back in.
EnglishCompose and Compose Multiplatform expert for UI development across Android, Desktop, iOS, and Web. Use whenever the user mentions Compose APIs (@Composable, remember, LaunchedEffect, NavHost, MaterialTheme, LazyColumn, Modifier, recomposition), Compose Multiplatform (commonMain, expect/actual, Res., ComposeUIViewController, UIKitView, ComposeViewport), Android TV (tv-material, D-pad, focus, Carousel), Material 3 motion, atomic design systems, design-to-code workflows, Paging 3, or navigation. Activates Review Mode on GitHub PR URLs and review phrases ("review this PR", "what's wrong with this"). Auto-detects Compose projects on sessionstart. Backed by actual androidx/androidx and JetBrains/compose-multiplatform-core source receipts. See " When this skill applies" in SKILL.md for the full trigger surface.
EnglishDrive a Windows machine over SSH via the NirCmd CLI and its NirSoft companion utilities — capture specific windows or regions, control audio (volume, mute, mediaplay), TTS via speak, lock workstation, list/activate windows, simulate keystrokes, plus scriptable NirSoft tools for network state (CurrPorts, WifiInfoView), system forensics (LastActivityView, BrowsingHistoryView, TurnedOnTimesView), open handles (OpenedFilesView), and file search (SearchMyFiles). Use whenever the user wants to control audio/volume, make Windows speak something, lock the workstation, list open ports / Wi-Fi APs / recent activity / open file handles on Windows, or do any other Windows-side action via NirCmd or a NirSoft companion CLI. For clipboard operations use the clipboard skill; for desktop screenshots prefer the screenshots skill. Defaults to ssh steamy-wsl, NirCmd at C:\tools\nircmd\nircmd.exe, NirSoft companions at C:\tools\nirsoft\; override via NIRCMDHOST, NIRCMDPATH, NIRSOFTDIR env vars.
EnglishUse when working with Tracearr media-server monitoring for Plex, Jellyfin, or Emby, including real-time sessions, stream analytics, account-sharing detection, trust scores, alerts, imports from Tautulli/Jellystat, Docker deployment, configuration, or Tracearr's public API.
EnglishUse when the user wants to live-test a WEB app/site end-to-end in a real browser and get a works/doesn''t-work + UI/UX report — not just write Playwright code. Triggers: "test my web app", "QA this site", "run E2E on the web app", "click through every feature and tell me what breaks", "review the UX of this web app", "does my web app work", "test the deployed site". Drives a real Chrome via Playwright over CDP (default http://127.0.0.1:9222), enumerates features from the DOM/ARIA tree, exercises each, captures screenshots + console/page/network errors, and emits a structured report. Sibling of android-app-testing and desktop-app-testing (shared report format). Does NOT fire for: writing a one-off Playwright script (use webwright), pure web design/build with no testing, or backend/API-only testing.

Claude Android Ninja
Use when building Android apps with Kotlin, Jetpack Compose, MVVM, Hilt, Room 3 (KSP, SQLiteDriver, Flow/suspend DAOs), and multi-module architecture. Triggers on requests to create Android projects, modules, screens, ViewModels, repositories, or Android architecture questions. Not for iOS, Flutter, React Native, KMP-only shared code without an Android app module, or backend-only APIs with no Android client.
Hand Off
Load the most recent save-to-md session log into a fresh session and brief the new agent on where the prior session left off. Use at the start of a new conversation when the user says "hand off", "pick up where we left off", "resume the last session", "continue from yesterday", "load the last session log", or otherwise signals they want the prior session's context restored.

Jetpack Compose Expert
Compose and Compose Multiplatform expert for UI development across Android, Desktop, iOS, and Web. Use whenever the user mentions Compose APIs (@Composable, remember, LaunchedEffect, NavHost, MaterialTheme, LazyColumn, Modifier, recomposition), Compose Multiplatform (commonMain, expect/actual, Res., ComposeUIViewController, UIKitView, ComposeViewport), Android TV (tv-material, D-pad, focus, Carousel), Material 3 motion, atomic design systems, design-to-code workflows, Paging 3, or navigation.
