A 12-agent AI development pipeline I designed in Claude Code. An orchestrator picks up Linear tickets, and specialized agents (planner, spec writer, frontend, backend, review, integration and more) hand work to each other by label, build against a shared contract, run parallel reviews, and escalate to a human after 3 rejected reviews. Backed by 37 custom agent skills and 55 release-automation scripts, it's how one engineer shipped 11 production releases of Ember in two weeks.
