openbooklet.com/s/dotnet-backend-expertopenbooklet.com/s/dotnet-backend-expert@1.0.0GET /api/v1/skills/dotnet-backend-expertThis skill should be used when the user is writing, reviewing, debugging, or architecting pure .NET backend code for Kestrel-hosted services. It provides expert critique for REST endpoints, SignalR hubs, TypeScript/React client integration shape, pragmatic Rust interop, application services, AppHost-aware project structure, EF Core and database boundaries, dependency injection lifetimes, OOP and SOLID quality, concurrency, and distributed-architecture tradeoffs. Use when the user asks "critique my .NET backend", "review this service", "should this be singleton or scoped", "structure my solution", "review my SignalR hub", "review my AppHost", "is this clean architecture", "should I use repositories", "fix my DbContext usage", "design my REST endpoints", "review my concurrency", or "should this be microservices".
dev-browser is a CLI that controls browsers using sandboxed JavaScript scripts. Scripts run in a QuickJS WASM sandbox (not Node.js) with Playwright Page API access plus dev-browser extensions (notably `snapshotForAI()`). Pages persist between script runs via named handles, enabling incremental multi
This skill should be used when the user wants to find, audit, or remove dead code, unused imports, unused functions, unused variables, duplicate implementations, or simplify a codebase. Works across all programming languages. Relevant when the user says "find dead code", "remove dead code", "remove unused imports", "find duplicate code", "simplify this codebase", "find unused functions", "find unused code", "remove commented out code", "what code is unused", "find orphaned files", "detect duplicate implementations", "find unreachable code", "clean up this codebase", or "audit for unused code".
Validate Electron desktop app UI using Playwright automation via the e-cli tool. Use when testing Electron app UI, validating after code changes, checking if tabs render, clicking through UI flows, taking screenshots for visual review, or debugging runtime import errors that typecheck doesn't catch. Works with any Electron project that has @playwright/test and electron in devDependencies. Use when the user asks "validate the electron app", "check the UI", "click through the app", "take a screenshot", "does the app render", "test the electron UI", "launch the app and check", "verify the app works", "is the app broken", or "debug a runtime error".
This skill should be used when the user is writing, reviewing, debugging, or architecting C++ firmware for ESP32 and variants (ESP32-S2, S3, C3, C6, H2, P4) using ESP-IDF or PlatformIO. Provides expert critique covering FreeRTOS task design, memory management (IRAM/DRAM/PSRAM), peripheral drivers (I2C/SPI/UART/GPIO), build systems (CMake/platformio.ini), power management, OTA updates, and embedded C++ best practices. Use when the user asks "review my ESP32 code", "fix FreeRTOS crash", "optimize memory usage", "debug I2C issue", "set up PlatformIO project", "review my CMakeLists", "search datasheet for this chip", "why is my task crashing", "configure deep sleep", or "help with ESP-IDF component structure".
This skill should be used when the user is writing, reviewing, debugging, or architecting Python backend code using Litestar or FastAPI with SQLAlchemy or Advanced Alchemy. Provides expert critique covering SOLID principles, hexagonal architecture, repository/service patterns, dependency injection, async correctness, ORM usage, API design, anti-pattern detection, and modern Python patterns for mature production backends. Use when the user asks "critique my Python backend", "review this controller", "fix my SQLAlchemy query", "structure my project", "is this SOLID", "review my repository", "optimize my API", "design my service layer", "help with dependency injection", "set up a Litestar project", "set up a FastAPI project", "create a repository pattern", "fix my async code", "review my database models", or "fix N+1 query".
`seam-probe` is a **generic** NDJSON probe for embedded-runtime seams. It ships **zero** app-specific knowledge. Everything app-specific is expressed in a small JSON **manifest** that the user (or you) writes and hands to the binary.
This skill should be used when the user is building, reviewing, or debugging SwiftUI views and apps. Detects iOS and Swift version from the project. Covers creating views, state management with @Observable, NavigationStack routing, animations, accessibility, performance optimization, Liquid Glass adoption, design systems, and clean code architecture. Use when the user asks things like "create a SwiftUI list view", "my @State isn't updating", "add navigation to my app", "make this accessible", "optimize SwiftUI performance", "add Liquid Glass to my toolbar", "fix my Swift concurrency warning", "set up SwiftData models", "critique my SwiftUI code", "fix my SwiftUI layout", "create a custom ViewModifier", or "add Dark Mode support".
web-interact is a browser automation plugin powered by the `web-interact` CLI. Scripts run in a QuickJS WASM sandbox with Playwright Page API access plus CDP-based element discovery and interaction. Pages persist between script runs via named handles, enabling incremental multi-step workflows.
