If you need durable workflow execution in Claude Code, this gives you the building blocks: named queues with configurable retries, shared state tracking, and cron triggers for scheduled tasks. Think Temporal or Inngest lite. Each pipeline step is a registered function, progress gets broadcast via streams, and you define queue behavior (backoff, concurrency, FIFO) in a config file. The 17.5K GitHub stars suggest iii-hq has real traction. It's not going to replace a full orchestration platform, but for embedding reliable multi-step processes directly into your agent workflows without standing up separate infrastructure, it's a solid choice. Just don't reach for every durability mechanism on simple tasks.
