Saves pipeline progress to .claude/pipeline-state.json after every phase so you can survive rate limits and interruptions during complex multi-phase work. The real discipline here is structuring your session upfront: GitHub issues and commits first, file-heavy phases last, mini-commits every three phases. When you resume, it shows you where you left off and lets you pick up or jump to a different phase. The schema and decision tree references are more elaborate than most skills bother with, which tells you this is built for sessions that actually span dozens of phases. If you're doing anything that might take an hour or risk hitting limits, the checkpoint discipline pays off.
