Individual skill
lamina
Product design skill for developers who build with AI coding agents. Use when you need to know what to build before prompting your agent — domain model, workflows, edge cases, product states, and UX gaps handled upfront. Works alongside Cursor, Claude Code, Codex, Gemini, Pi. Any stack, any UI library. Do NOT use for visual styling, pixel layouts, or writing app source.

# Lamina — For Developers Who Build with AI
**Design how it works.**
Lamina runs alongside your AI coding agent — Cursor, Claude Code, Codex, Gemini, Pi. It helps you know what to build before you prompt: edge cases, UX gaps, product states, and invariants in a transactional product graph your agent implements. Verified with isolated Persona Missions after you ship. Does not write your app source.
## When to use
Invoke Lamina when the task involves:
- New features where domain rules, user behavior, and system invariants all matter
- Multi-step flows (onboarding, checkout, settings, wizards)
- Permission-sensitive or multi-actor interactions
- Empty states, error handling, or edge cases tied to business rules
