Iii Architecture Patterns

Shows you how to compose iii primitives into six backend patterns: durable workflows with retry and progress tracking, reactive backends that sync views and push updates via state triggers, agentic pipelines where specialized functions hand off work through queues, event-driven CQRS with command functions and projection subscribers, effect pipelines for pure composition, and trigger-transform-action automation chains. Each pattern includes a decision table, working code in TypeScript, Python, and Rust, and selection rules. Use this when you're building complete product behavior, not just calling one SDK method. It assumes you already know the primitives and need architectural recipes for chaining them together with the right delivery guarantees.

Architecture Patterns

Use this skill when the task is larger than one function or observer. Pick the pattern from the requirement, then implement it with workers, functions, observers, state, queues, and streams.
