Master Python asynchronous programming with asyncio, async/await, and concurrent.futures. Use for async code and concurrency patterns.
Baseline C# skill loaded for every .NET code path. Guides language patterns (records, pattern matching, primary constructors, C# 8-15), coding standards, async/await, DI, LINQ, serialization, domain modeling, concurrency, Roslyn analyzers, globalization, native interop (P/Invoke, LibraryImport, ComWrappers), WASM interop (JSImport/JSExport), and type design. Spans 25 topics. Do not use for ASP.NET endpoint architecture, UI framework patterns, or CI/CD guidance.
Discover optimal autoscaling parameters for a Deco site by analyzing Prometheus metrics. Correlates CPU, concurrency, and latency to find the right scaling target and method.
Use this skill when building Android applications with Kotlin. Triggers on Jetpack Compose UI, Room database, Kotlin coroutines, Play Store publishing, MVVM/MVI architecture, ViewModel, StateFlow, Hilt dependency injection, Navigation Compose, Material 3, APK/AAB builds, ProGuard, and Android app lifecycle management. Covers modern Android development with declarative UI, reactive state, structured concurrency, and production release workflows.
Correct usage of context.Context in Go: propagation, cancellation, timeouts, deadlines, values, and common anti-patterns. Use when: "context usage", "context.Context", "context cancellation", "timeout", "context.WithTimeout", "context.WithCancel", "context values", "context propagation". Do NOT use for: concurrency patterns beyond context (use go-concurrency-review), HTTP middleware context (use go-api-design), or error handling (use go-error-handling).
Writes, reviews, and debugs idiomatic Rust code with memory safety and zero-cost abstractions. Implements ownership patterns, manages lifetimes, designs trait hierarchies, builds async applications with tokio, and structures error handling with Result/Option. Use when building Rust applications, solving ownership or borrowing issues, designing trait-based APIs, implementing async/await concurrency, creating FFI bindings, or optimizing for performance and memory safety. Invoke for Rust, Cargo, ownership, borrowing, lifetimes, async Rust, tokio, zero-cost abstractions, memory safety, systems programming.
AI SDLC declarative workflow planning. Use when an AI assistant needs to validate a versioned workflow, plan typed dependency steps, evaluate bounded conditions, enforce approval gates, attach deterministic hooks, detect cycles, or create safe dependency waves with sequential fallback when host concurrency or isolation is unavailable. Supports `--quick-flow` and `--full-flow`.
Use when implementing or debugging ANY network connection, API call, or socket. Covers URLSession, Network.framework, NetworkConnection, deprecated APIs, connection diagnostics, structured concurrency networking.
Modern Rust development with cargo, rustc, clippy, rustfmt, async programming, and memory-safe systems programming. Covers ownership patterns, fearless concurrency, and the modern Rust ecosystem including Tokio, Serde, and popular crates. Use when user mentions Rust, cargo, rustc, clippy, rustfmt, ownership, borrowing, lifetimes, async Rust, or Rust crates.
Guidance for writing, reviewing, and debugging Unreal Editor for Fortnite (UEFN) Verse code using Epic's official language documentation. Use when implementing Verse devices, classes, functions, control flow, containers, failure contexts, specifiers/attributes, modules/imports, effects, concurrency, or translating logic into valid Verse.
Use when you need to design, review, or improve REST APIs with Spring Boot — including HTTP methods, resource URIs, status codes, DTOs, versioning, deprecation and sunset headers, content negotiation (JSON and vendor media types), ISO-8601 instants in DTOs, pagination/sorting/filtering, Bean Validation at the boundary, idempotency, ETag concurrency, HTTP caching, error handling, security, API documentation, controller advice, and problem details for errors.

Use when the user asks for a broad codebase review, substantial PR/branch review, architecture audit, tech-debt scan, cleanup assessment, structural sanity check, or design-alignment review. Default workflow: use sub-agents when available unless specifically forbidden; do not require the user to mention sub-agents, council mode, delegation, or parallel review. Focus on cruft, duplication, weak boundaries, missed reuse, lifecycle/concurrency risks, test/roadmap drift, and code aesthetics. Do not use for narrow bug fixes, ordinary small-diff reviews, frontend visual QA, repo-onboarding docs, or OpenAI Agents SDK production-readiness review. Output evidence-backed findings first, then pressure points, design alignment, open questions, and follow-through.
