What problem does it solve? Debugging the Zeus Bitcoin/Lightning wallet is hard because logs, capabilities, and settings are scattered across seven node backends, native Android/iOS layers, and generated code. This Skill tells you exactly where every log lives, how to read native and JS-layer output, how to inspect REST/WebSocket/Tor traffic, and provides scripts that extract ground truth from the codebase instead of stale documentation. ## Core Features & Use Cases - Log Access Per Backend: Exact file paths and commands for embedded LND lnd.log on Android/iOS, LDK Node ldk_node.log, adb logcat tag filters, Metro and Xcode consoles, plus in-app log viewers. - In-App Diagnostics: Use the Developer Tools view (18 raw RPC probes), Keychain Recovery scanner, and Activity CSV export to compare app state against node truth. - Network Inspection: Understand TLS verification defaults, WebSocket-bypasses-Tor behavior, Tor request paths, and the request-dedup cache that can replay stale failures. - Measurement Scripts: Run find-debt.sh for TODO/FIXME census, capability-matrix.sh for the live supports* matrix across all 7 backends, and list-settings-defaults.sh to catch settings default drift. - Use Case: A user's embedded LND node appears stuck syncing. Use this Skill to tail lnd.log via adb, watch the WalletState machine in logcat, check SyncStore block-height polling, and determine whether the issue is neutrino peers or an RPC timeout. ## Quick Start Ask the assistant to show you where the embedded LND logs are on Android and how to tail them from a connected device.
