How is observability managed with this skill?

The skill enforces the use of OpenTelemetry instrumentation, DataDog logging, and specific traceException wrappers for error handling.

What backend technologies does this skill support?

This skill is optimized for Next.js 14, tRPC, Express, TypeScript, BullMQ, Prisma (PostgreSQL), ClickHouse, and Redis.

How does this skill handle multi-tenancy?

It implements strict tenant isolation patterns using projectId filtering and role-based entitlement checks for all resource access.

Can I use this for public API development?

Absolutely. It includes specific patterns for REST-based public APIs, including versioning, Zod validation, and basic auth middleware.

Does it include guidelines for background processing?

Yes, it provides checklists and architectural patterns for creating BullMQ queue producers and processors within an Express worker package.

API Development

Implements standardized architectural patterns and best practices for Next.js, tRPC, and BullMQ backend environments.

This skill provides a comprehensive framework for developing robust backend systems within the Langfuse monorepo architecture. It guides Claude in creating consistent tRPC routers, public REST APIs, and BullMQ background workers while enforcing a strict layered architecture where procedures and processors delegate business logic to dedicated services. It ensures high standards for multi-tenant isolation, dual-database operations (PostgreSQL/ClickHouse), and integrated observability via OpenTelemetry, making it essential for building scalable, production-grade TypeScript applications.
