Protocol Buffers and Interface Definition Languages for service contracts
Use when the workflow lacks error handling, has been failing in production, or needs retry logic, fallback strategies, and circuit breakers.
Build ASP.NET Core 8+ backend services with EF Core, auth, background jobs, and production API patterns.
RISC-V assembly skill for RV32/RV64 programming. Use when working with the RISC-V ISA, calling conventions (psABI), inline assembly with GCC/Clang, understanding extension naming (IMAFD), compressed instructions, or simulating RISC-V with QEMU and GDB remote debugging. Activates on queries about RISC-V assembly, RV32, RV64, RISC-V calling convention, RISC-V inline asm, RISC-V extensions, QEMU RISC-V, or RISC-V GDB.
Rust async internals skill for understanding and debugging async Rust. Use when understanding the Future trait and poll model, Pin and Unpin, tokio task scheduling, debugging async stack traces with tokio-console, tracking waker leaks, using select! and join!, or avoiding blocking in async contexts. Activates on queries about Rust async internals, Future poll, Pin, Unpin, tokio-console, waker, async stack traces, select!, join!, or blocking in async.
Microservice architecture patterns — service decomposition, inter-service communication, API gateway, saga pattern, event-driven architecture, service mesh, circuit breaker, CQRS, event sourcing. Activate on "microservices", "service decomposition", "saga pattern", "API gateway", "event-driven", "service mesh", "circuit breaker", "CQRS", "event sourcing", "bounded context", "strangler fig", "distributed transactions", "choreography vs orchestration". NOT for monolith design, serverless functions, or Kubernetes infrastructure.
Use when securing Fastify API endpoints with JWT Bearer token validation, scope/permission checks, or stateless auth - integrates @auth0/auth0-fastify-api for REST APIs receiving access tokens from frontends or mobile apps.
Use this skill whenever the user wants to integrate Loops from application code, backend services, webhook handlers, or server-side automation. This includes the Loops HTTP API and official SDKs for server-side contact, contact-property, mailing-list, event, API-key-validation, and transactional-email workflows. Trigger on phrases like "Loops API", "Loops SDK", "send a Loops event from my app", "add a contact to Loops in a webhook", "send a transactional email from backend code", or any time the user wants to integrate Loops into their app, backend, webhook, or automation. Do not trigger for CLI or shell-only requests.
[Pragmatic DDD Architecture] Guide for Authentication configuration and the `auth` Bounded Context. Use when modifying auth flows, adding social providers, configuring email templates/Resend, working with the Better Auth client/server configurations, or modifying `src/auth/` components and components dependent on session handling.
[Pragmatic DDD Architecture] Guide for the overall project architecture, Domain-Driven Design (DDD) principles, Modular Monolith (Bounded Contexts) organization, and file structure. Use when deciding where to place a new file, creating a new module, or understanding the application's layers and dependency flow.
Modern, powerful structured logging for Python using structlog. Use when adding or improving logging in Python projects, configuring structlog for dev/production, working with contextvars for request-scoped logging, integrating structlog with stdlib logging, or writing tests for logging behavior.
Write application code that integrates with third-party tools via the Truto unified API. Covers API calls, webhook handlers, connection flows, and data access patterns for use in the user's codebase.
