Dbos Typescript

This covers DBOS's TypeScript SDK for building fault-tolerant applications with durable workflows. You'd reach for it when you need code that survives crashes and restarts without losing progress, like payment processing or multi-step API orchestrations. The skill walks through the core primitives: workflows for orchestration, steps for external calls and non-deterministic work, and queues for managing concurrency. The determinism requirements are strict, workflows can't touch global state or call external services directly, but that's how it guarantees reliability. It includes practical patterns for workflow communication and testing, plus guidance on using DBOSClient from outside your DBOS app. The rule categories are well organized by priority, making it easy to find what matters when you're actually writing code.
