Not for: device/browser matrix strategy in the abstract — use cross-browser-testing; app startup/memory/battery profiling depth — use performance-testing; mobile screenshot diffing — use visual-testing. Related: ci-cd-integration, cross-browser-testing, performance-testing, test-data-management, test-reliability.
Guides the agent through adding, configuring, and using the Capawesome desktop platforms for Capacitor — @capawesome/capacitor-electron and @capawesome/capacitor-tauri. Covers choosing between Electron and Tauri, installation and scaffolding, sync/run workflows, live reload, deep links, plugin compatibility (Electron plugin implementations and web fallback; Tauri plugin tiers), packaging, and app updates. Do not use for the Android or iOS platforms, installing individual Capacitor plugins, migrating Capacitor apps or plugins to newer versions, or non-Capacitor desktop frameworks.
