Use only when explicitly invoked as lamina-design. Turn an incomplete product idea or brownfield change into a minimum sufficient product behavior graph: actors, entities, operations, workflows, rules, dependencies, decisions, persona perspectives, and distinct risks; then generate an implementation-ready contract.
Use only when explicitly invoked as lamina-init. Turn an incomplete product idea into usable business context and evidence-grounded personas, asking only high-leverage questions and labeling provisional assumptions for later product-graph design.
Product design workflows — domain contracts, implement brief, verify loop. Load via Read or Skill tool when /lamina-* workflows need it.
Use only when explicitly invoked as lamina. Route product design for developers building with AI — design, verify, or direct capability answers.
Use only when explicitly invoked as lamina-verify. Verify a live or brownfield product against its product graph: critical promises, reachable workflows, authority, invariants, state integrity, recovery, accessibility, and contract drift; emit evidence-backed fixes before merge.
Business context UX guidance. Use when bootstrapping Lamina for a project; answering business questions UX work needs; updating context after a pivot or scope change.

| description | Translate product intent into traceable critical promises, graph nodes, observable scenarios, assumptions, and scope without prescribing unnecessary implementation details. |
Write requirements as traceable product behavior:
intent.critical_promises[]: outcomes the product must preserve.scenarios[]: observable distinct risks and recovery.decisions: confirmed choices, assumptions, and policy forks.intent.scope: current in/out boundaries.traceability[]: promise-to-graph links.Mark every node's criticality, provenance, confidence, and relevance. Keep stack and vendor choices out unless the user explicitly constrained them. Defer non-current behavior instead of padding the contract.
