Expertise in binary lifting techniques - converting machine code to LLVM IR for analysis, decompilation, and recompilation. Use this skill when working on reverse engineering, binary analysis, deobfuscation, or converting binaries to higher-level representations.
WebGL "zoom blur" effect for full-screen background image transitions (Three.js + custom GLSL shader, mouse parallax, scroll/click/key navigation) for hero sections/image slideshows. Call when the user says "hiệu ứng blur ảnh", "chuyển ảnh mờ dần kiểu zoom", "webgl blur transition", "gallery ảnh full-screen kiểu blur", or /blur. DIFFERENT from `dark-mode-maker` (circle-reveal theme switch) — this is an IMAGE TRANSITION effect, not a theme switch.
Explore user intent, requirements, and design options through collaborative dialogue before implementation. Use before building new features, components, or systems — whenever the user describes something to build and design decisions are involved. Triggers: "brainstorm", "help me design", "think through the requirements", "头脑风暴", "设计方案", "梳理需求". Not for bug fixes, config changes, or tasks with an obvious implementation path.
CarPlay framework for iOS in-car applications — audio, communication, navigation, parking, EV charging, quick food ordering, fueling, driving task, public safety, and voice-based conversational apps. Includes widgets, live activities, CarPlay Ultra, and instrument cluster support.

Analyze codebases for anti-patterns and code smells via ast-grep structural matching across JS, TS, Python, Vue, React. Use when reviewing code quality, identifying tech debt, or doing broad code analysis. Pairs with /code-antipatterns.
Authoritative framework for reviewing the design quality of proposed code changes — before implementation. Evaluates architecture-level quality attributes (testability, modularity, reliability, scalability, dependency direction via ISO 25010 + Clean Architecture + SDP) and code-level metrics (accidental complexity, coupling via Myers/Connascence, cohesion, change amplification, tech debt, cyclomatic/cognitive complexity, Law of Demeter) plus a security pass (OWASP Top 10). Use this skill whenever a proposed solution involves code changes and you need to assess whether the code is well-designed — not just whether it works, but whether it is maintainable, testable, and does not introduce design debt. Triggers — 「代码审查」「代码设计审查」「代码设计质量」「审查代码设计」「代码架构审查」「设计质量评估」「代码质量评审」「这个代码设计合理吗」「耦合度审查」「代码可维护性」 / code design review, code architecture review, design quality assessment, coupling analysis, maintainability review.
Code review automation for TypeScript, JavaScript, Python, Go, Swift, Kotlin, C#, .NET, Java, C, C++, Rust, Ruby, PHP, and Dart/Flutter. Analyzes PRs for complexity and risk, checks code quality for SOLID violations and code smells, and generates review reports. Use when reviewing pull requests, analyzing code quality, identifying issues, or generating review checklists
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
Adds, changes, or reviews a screen, sheet, dialog, or destination slice (endpoint to repository to ViewModel to UI to navigation to DI to tests) in a Compose or CMP project. Use when adding a screen, building a new feature, adding a ViewModel or destination, wiring list/detail or a form screen, scaffolding a slice, or reviewing a feature change. Covers Contract.kt, launchGuarded wiring, SavedStateHandle drafts, the state matrix, and new-feature.sh. Do NOT use for routing or architecture (compose-architecture), pure refactors, Gradle work (compose-project), recomposition or styling (compose-ui), repository or persistence work (compose-data), or expect/actual splits (compose-platform).
Writes and reviews composables for Compose and CMP: the Route/Screen/leaf split, state-read placement and stability, loading/empty/error UX states, LazyColumn lists and grids, animation choice, accessibility and semantics, design-system tokens, CMP Res resources, Coil images, and keyboard/focus. Use when touching @Composable code, recomposition, stability, LazyColumn, animation, shimmer or skeleton, accessibility, theme, colors, Res.string, Coil, focus, or keyboard. Do NOT use for MVI, error tiers, or module graph (compose-architecture), ViewModel or data work (compose-feature, compose-data), Gradle or module work (compose-project), or expect/actual splits (compose-platform).
Use this skill to connect ADB to an Android 11+ device wirelessly with the modern `adb pair` flow (pairing code or QR via `Settings → Developer options → Wireless debugging`), then `adb connect <host:port>` and `adb disconnect`, plus mDNS auto-discovery via `adb mdns check` / `adb mdns services` and the `_adb-tls-pairing._tcp` / `_adb-tls-connect._tcp` service types. Covers the ADB v34+ default mDNS backend (Openscreen on Linux/Windows, not Bonjour as the public doc says), the legacy `adb tcpip <port>` + `adb connect` path that pre-dates pairing, security caveats (corporate Wi-Fi blocks p2p; flat LAN exposure), version requirements (Android 11/API 30 for phones, Android 13/API 33 for TV+Wear), and the `ADB_MDNS_OPENSCREEN` / `ADB_MDNS_AUTO_CONNECT` environment variables. Use when the user mentions `adb pair`, `adb connect`, "wireless debugging", "QR code pairing", `_adb-tls-connect`, "Openscreen vs Bonjour", `adb tcpip 5555`, or "device not connecting after pairing successfully".
Use when sending local changes back to the project (an added journal profile, a fixed checklist item, an adapted skill) or reporting a false positive or bug. Finds what changed, scans it for patient data, shows every line and sends nothing until you confirm.
For cross-project CRD recipients: independently assess long-term proposals and state a position, provide a focused response, or report implementation results. Proposers use crd. For non-Kubernetes CRDs or code implementation. When code changes are needed, generate a development plan that includes the source CR and an agreement to report back on completion.
Execute database migrations across ORMs and platforms with zero-downtime strategies, data transformation, and rollback procedures. Use when migrating databases, changing schemas, performing data transformations, or implementing zero-downtime deployment strategies.
Debugging workflows for Python (pdb, debugpy), Go (delve), Rust (lldb), and Node.js, including container debugging (kubectl debug, ephemeral containers) and production-safe debugging techniques with distributed tracing and correlation IDs. Use when setting breakpoints, debugging containers/pods, remote debugging, or production debugging.
Stress-test an existing implementation plan and selectively strengthen weak sections with targeted research. Use when a plan needs more confidence around decisions, sequencing, system-wide impact, risks, or verification. Best for Standard or Deep plans, or high-risk topics such as auth, payments, migrations, external APIs, and security. For structural or clarity improvements, prefer document-review instead.
Design, build, audit, redesign, study, and polish distinctive, production-grade web interfaces without generic AI aesthetics. Use for landing pages, websites, product UI, dashboards, portfolios, frontend components, HTML/CSS/JS, React, Next.js, Vue, Svelte, design-system work, visual redesigns, UI critiques, accessibility reviews, responsive hardening, or requests to remove AI slop
Design, build, evaluate, govern, monitor, evolve, and retire digital twins and federated twin universes for software systems, engineering processes, agentic software factories, infrastructure, and cyber-physical operations. Use when a task involves digital-twin architecture, digital thread, simulation, predictive maintenance, twin health, agent authority, or dark-factory design. Do not use for ordinary observability dashboards, static dependency graphs, generic AI governance, or operating one named infrastructure tool without a twin-specific representation and feedback loop.
Provides comprehensive guidance for Django framework including models, views, templates, forms, admin, REST framework, and deployment. Use when the user asks about Django, needs to create web applications, implement models and views, or build Django REST APIs.
Migrate an existing Django API from Django REST Framework to django-modern-rest while preserving routes, request/response contracts, auth, permissions, throttling, pagination, and test coverage. Use when replacing APIView/ViewSet/GenericAPIView and DRF serializers/routers with dmr controllers/routers and typed DTOs.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
