This skill should be used when the user asks to "audit this code", "deep analysis before security review", "build architectural context", "line-by-line code review", or needs ultra-granular analysis before vulnerability discovery. Provides structured context-building methodology with First Principles, 5 Whys, 5 Hows micro-analysis patterns.
Use when implementing on-device AI with Apple's Foundation Models framework (iOS 26+), building summarization/extraction/classification features, or using @Generable for type-safe structured output.
Build React Native 0.76+ apps with Expo SDK 52-54. Covers mandatory New Architecture (0.82+/SDK 55+), React 19 changes, SDK 54 breaking changes (expo-av, expo-file-system, Reanimated v4), and Swift iOS template. Prevents 16 documented errors. Use when building Expo apps, migrating to New Architecture, upgrading to SDK 54+, or fixing Fabric, TurboModule, propTypes, expo-updates crashes, or Swift AppDelegate errors.
Interactive LeetCode-style teacher for technical interview preparation. Generates coding playgrounds with real product challenges, teaches patterns and techniques, supports Python/TypeScript/Kotlin/Swift, and provides progressive difficulty training for data structures and algorithms.
Detects timing side-channel vulnerabilities in cryptographic code. Use when implementing or reviewing crypto code, encountering division on secrets, secret-dependent branches, or constant-time programming questions in C, C++, Go, Rust, Swift, Java, Kotlin, C#, PHP, JavaScript, TypeScript, Python, or Ruby.

Debug applications using the dbg CLI debugger. Supports Node.js (V8/CDP), Bun (WebKit/JSC), and native code via LLDB (DAP). Use when: (1) investigating runtime bugs by stepping through code, (2) inspecting variable values at specific execution points, (3) setting breakpoints and conditional breakpoints, (4) evaluating expressions in a paused context, (5) hot-patching code without restarting (JS/TS), (6) debugging test failures by attaching to a running process, (7) debugging C/C++/Rust/Swift with LLDB, (8) any task where understanding runtime behavior requires a debugger. Triggers: "debug this", "set a breakpoint", "step through", "inspect variables", "why is this value wrong", "trace execution", "attach debugger", "runtime error", "segfault", "core dump".
Write code using Agora SDKs (agora.io) for real-time communication. Covers RTC (video/voice calling, live streaming, screen sharing), RTM (signaling, messaging, presence), Conversational AI (voice AI agents), Cloud Recording, Server Gateway, and server-side token generation. Use when the user wants to build real-time audio/video applications, integrate Agora SDKs (Web JS/TS, React, iOS Swift, Android Kotlin/Java, Go, Python), manage channels, tracks, tokens, use RTM for messaging/signaling, record RTC sessions, or build Conversational AI with the agent-toolkit. Triggers on mentions of Agora, agora.io, RTC, RTM, video calling, voice calling, real-time communication, screen share, screen sharing, record session, record calls, Cloud Recording, Server Gateway, Linux media SDK, agora-rtc-sdk-ng, agora-rtc-react, agora-rtm, conversational AI with Agora, Agora token generation, Agora authentication, agora-agent-client-toolkit, agora-agent-client-toolkit-react, agora-agent-server-sdk, AgoraVoiceAI, AgoraClient, useConversationalAI, useTranscript, useAgentState, agent transcript, agent state hook.
