The skills
Pick a layer, run a skill.
Nine AI skills — one for each of the seven layers of product design, plus a diagnostic and a framework primer. Tool-agnostic; install once, run in your AI tool of choice.
- Layer 1
/layers-observed-behaviourObserved behaviour
Plan and synthesise user research at the observed-behaviour layer — into grounded, confidence-rated findings about what users actually do.
- Layer 2
/layers-domainThe domain
Map domain concepts, terminology conflicts, and bounded contexts — the raw material the conceptual model is built from.
- Layer 3
/layers-user-needsUser needs
Elicit and prioritise user needs, pains, and desires — the opportunities that feed product strategy.
- Layer 4
/layers-product-strategyProduct & service strategy
Connect user opportunities to business outcomes and solution bets — and test the riskiest assumptions cheaply.
- Layer 5
/layers-conceptual-modelConceptual model
Define the product’s objects, relationships, states, and vocabulary independently of any interface — the most load-bearing layer.
- Layer 6
/layers-interaction-flowInteraction structure & flow
Map interaction structure and flow — places, affordances, edge cases, and failure paths — without committing to visual form.
- Layer 7
/layers-surfaceSurface
Audit and decide the surface against the layers below — vocabulary, object consistency, feedback, hierarchy, and accessibility.
