Master Django 5.x with async views, DRF, Celery, and Django Channels. Build scalable web applications with proper architecture, testing, and deployment. Use PROACTIVELY for Django development, ORM optimization, or complex Django patterns.
Master Python asyncio, concurrent programming, and async/await patterns for high-performance applications. Use when building async APIs, concurrent systems, or I/O-bound applications requiring non-blocking operations.
Implement Linkerd service mesh patterns for lightweight, security-focused service mesh deployments. Use when setting up Linkerd, configuring traffic policies, or implementing zero-trust networking with minimal overhead.
Configure secure, high-performance connectivity between on-premises infrastructure and cloud platforms using VPN and dedicated connections. Use when building hybrid cloud architectures, connecting data centers to cloud, or implementing secure cross-premises networking.
Configure Istio traffic management including routing, load balancing, circuit breakers, and canary deployments. Use when implementing service mesh traffic policies, progressive delivery, or resilience patterns.
Expert Kubernetes architect specializing in cloud-native infrastructure, advanced GitOps workflows (ArgoCD/Flux), and enterprise container orchestration. Masters EKS/AKS/GKE, service mesh (Istio/Linkerd), progressive delivery, multi-tenancy, and platform engineering. Handles security, observability, cost optimization, and developer experience. Use PROACTIVELY for K8s architecture, GitOps implementation, or cloud-native platform design.
Use when working with incident response incident response
Principles for building reusable coding systems. Use when designing modules, APIs, CLIs, or any code meant to be used by others. Based on "A Philosophy of Software Design" by John Ousterhout. Covers deep modules, complexity management, and design red flags.
Use when working with collection data structures in Stacks — chaining array operations, Laravel-style collection methods, mapping, filtering, reducing, or grouping. Covers @stacksjs/collections which wraps ts-collect.
Use when working with the event system in a Stacks application — dispatching events, listening for events, model events, wildcard listeners, the event emitter, or event-driven architecture. Covers @stacksjs/events, app/Events.ts, app/Listener.ts, and app/Listeners/.
Use when working with the Stacks ORM — defining models with defineModel(), model relationships (hasOne, hasMany, belongsTo, belongsToMany, morphOne, hasManyThrough), attributes, traits, factories, computed properties, query building, transactions, or the 50+ built-in models. Covers @stacksjs/orm, storage/framework/orm/, and storage/framework/models/.
Functional programming patterns with immutable data. Use when writing logic, data transformations, or encountering mutation bugs. Covers immutability violations catalog, pure functions, composition, early returns, and options objects. Do NOT over-apply heavy FP abstractions (monads, fp-ts) unless the project requires them.
Unix-composable CLI design patterns. Use when building CLI tools, designing command trees, implementing output layers, or testing CLI behavior. Covers stream separation (stdout/stderr), format flags (--json/--plain), exit codes, TTY detection, composability, and error design. Language-agnostic principles; TypeScript implementation patterns in resources/. For API design (REST, HTTP), see api-design.
Domain-Driven Design patterns for TypeScript. Use when implementing ubiquitous language, value objects, entities, aggregates, domain events, domain services, or bounded contexts. Only applies to projects that explicitly use DDD. Do NOT use for simple CRUD or projects without domain modeling.
Hexagonal (ports and adapters) architecture patterns for TypeScript. Use when implementing ports, adapters, dependency inversion, or domain isolation. Only applies to projects that explicitly use hexagonal architecture. Do NOT use for projects without ports/adapters structure.
12-Factor App patterns for deployable applications. Use when configuring environment variables, connecting to backing services, structuring application startup/shutdown, or handling graceful shutdown and process signals. Applies to any deployed application (services, APIs, frontends, workers). Server-specific factors (port binding, concurrency, disposability) apply only to backend services.
This rule helps in writing API decisions for new components of blade design system
Guides the design of safely disposable code through contracts (traits/interfaces) and dependency inversion. Use when designing new modules, refactoring existing code, or making architectural decisions about component boundaries.
Persistent memory patterns for cross-session learning and context retention
Domain-Driven Design architecture for claude-flow v3. Implements modular, bounded context architecture with clean separation of concerns and microkernel pattern.
AI design specialist skill with DESIGN.md management, anti-pattern enforcement, optional Stitch MCP integration, and component library guidance. Covers typography, color systems, motion design (motion/react, GSAP, Three.js), responsive-first layouts, and accessibility (WCAG 2.2).
