Dbos Python

This gives Claude the patterns for building fault-tolerant Python apps with DBOS's durable workflow system. It covers the critical stuff like proper lifecycle setup (you need to configure and launch DBOS in your main function), the workflow and step model (external calls must be steps, workflows must be deterministic), and concurrency control through queues. The guidelines are organized by priority, from lifecycle basics to advanced patterns, with specific guardrails like not calling start_workflow from steps and avoiding global state mutations. If you're building systems that need to survive failures or coordinate distributed work in Python, the workflow communication patterns and queue controls are worth the read.
