Understand implementation details of .NET code by decompiling assemblies. Use when you want to see how a .NET API works internally, inspect NuGet package source, view framework implementation, or understand compiled .NET binaries.
Managing local .NET tools with dotnet-tools.json for consistent tooling across development environments and CI/CD pipelines.
Expert-level Flask web development, REST APIs, extensions, and production deployment
Rust performance optimization covering memory allocation, ownership efficiency, data structure selection, iterator patterns, async concurrency, algorithm complexity, compile-time optimization, and micro-optimizations. Use when optimizing Rust code performance, profiling hot paths, reducing allocations, or choosing optimal data structures. Complements the rust-refactor skill (idiomatic patterns and architecture). Does NOT cover code style, naming conventions, or project organization (see rust-refactor skill).
Expertise in real-time multiplayer networking, lag compensation, and authoritative server architectureUse when "multiplayer game, netcode, client-server game, P2P networking, lag compensation, rollback networking, game server, matchmaking, lobby system, player synchronization, state replication, dedicated server, authoritative server, tick rate, network prediction, interpolation, extrapolation, GGPO, lockstep, real-time multiplayer, networking, multiplayer, gamedev, realtime, client-server, p2p, netcode, synchronization, lag-compensation, matchmaking" mentioned.
Kotlin + Arrow typed error handling using Raise DSL and wrapper types (Either/Option/Ior/Result/nullable), including validation with accumulation, interop with exceptions, and custom error wrappers. Use for designing or refactoring error modeling, converting exception-based flows, building smart constructors, accumulating validation errors, or integrating Outcome/Progress-style wrappers with Arrow.
Use when working in a Ruby project - provides authoritative sources for documentation, typing, and tooling
Async job processing patterns for background tasks, Celery workflows, task scheduling, retry strategies, and distributed task execution. Use when implementing background job processing, task queues, or scheduled task systems.
Develop custom Home Assistant integrations, config flows, entities, and platforms. Use when working with manifest.json, custom components, config_flow.py, entity base classes, or device registry. Activates on keywords: integration, custom component, config flow, entity, platform, manifest.json, device_info.
Wave-based parallel scheduling for DAG execution. Manages execution order, resource allocation, and parallelism constraints. Activate on 'schedule dag', 'execution waves', 'parallel scheduling', 'task queue', 'resource allocation'. NOT for building DAGs (use dag-graph-builder) or actual execution (use dag-parallel-executor).
Implementation workflows and decision trees for Frappe Document Controllers. Use when determining HOW to implement server-side DocType logic: lifecycle hooks, validation patterns, autoname, submittable workflows, controller override. Triggers: how do I implement controller, which hook to use, validate vs on_update, override controller, submittable document, autoname pattern, flags system.
This skill should be used when working with Firebase projects, including initializing projects, adding Cloud Functions or Firestore collections, debugging emulator issues, or reviewing Firebase code. Triggers on "firebase", "firestore", "cloud functions", "emulator", "firebase auth", "deploy to firebase", "firestore rules".
