Hyperstack's gate skill enforcement pattern - Iron Laws, 1% Rule, rationalization tables, <HARD-GATE> blocks, and the "spirit of the rule is the letter of the rule" clause - was adopted from superpowers. The core insight is that AI compliance gates need to be written adversarially to survive model pressure. We agreed, and built on it.
Five Hyperstack workflow skills (ship-gate, debug-discipline, run-plan, deliver, forge-plan) are structurally derived from their superpowers equivalents. They have since been extended with MCP integration, DESIGN.md pipeline hooks, and Hyperstack-specific domain content.
Everything else - the MCP server, 11 plugins, 79 tools, designer engine, DESIGN.md pipeline, React Flow / Motion / Lenis / Echo / Go / Rust / design tokens domain content, shadcn expert, and SessionStart hook - has no equivalent in superpowers and is original work.
The designer plugin's knowledge base is distilled from publicly available design research and real-world design systems:
- Cognitive psychology - Fitts's Law, Hick's Law, Miller's Law, Gestalt principles, Von Restorff effect, Serial Position effect, Peak-End Rule, Doherty Threshold
- UX heuristics - Jakob Nielsen's 10 usability heuristics
- Typography and layout - Bringhurst's Elements of Typographic Style, Müller-Brockmann's grid systems
- Design systems - Patterns observed across Linear, Stripe, Vercel, Apple HIG, Carbon, shadcn, Notion, Supabase, and Figma - used as reference, not reproduced
The design-patterns-skill draws on principles from:
- Clean Code - Robert C. Martin
- The Pragmatic Programmer - Hunt and Thomas
- Code Complete - Steve McConnell
- Refactoring - Martin Fowler
- Design Patterns - Gang of Four
