System Level's Claude Code plugin marketplace.
npx claudepluginhub systemlevel/iterative-developmentAn iterative implementation methodology that pairs with superpowers. Extracts requirements with proof obligations from large spec collateral, defines a walking skeleton that closes a real journey, then loops through audited sprints building a behavior evidence corpus until an auditor confirms the product matches the spec. Designed for comprehensive or ambiguous specs where the upfront writing-plans flow loses the plot.
