Early Access — Highly opinionated workflow designed for one person shipping fast. Some commands encourage skipping manual review. Not suitable for teams with established code review processes.

Solo founders and small teams who want an opinionated, ship-fast Claude Code setup. Adapt the patterns rather than copying wholesale — some commands skip manual review.
