Establish or extend a UKPT project's design system in :platform:client:design — author the identity (palette, type scale, typefaces, principles, prohibitions) over the template's neutral scaffold, choose what primitives are built on, and add new primitives together with their doc page and doc-surface golden. Use when setting up a project's design system, changing its tokens, or adding a design-system component.
Scaffold a new feature vertical slice :feature:<name>:{api,client,server} in UKPT — the three build files, the Compose/Enro client (destination, screen, viewmodel, state, snapshot test), the server stub, the settings include, and the Koin DI + app wiring — modeled on :feature:core. Use when adding a new feature module to the project.
Turn a fresh copy of the ukpt template (zip download or GitHub "use this template") into a real project — rename the packages/app identity, set up the git repo and submodules, and write the .ukpt/template.json marker that makes future ukpt-template-update runs possible. Use when starting a new project from ukpt.
Update a project that was created from the ukpt template to the latest template version — dependency and submodule bumps, build-logic and skill updates, architecture rule changes, and convention migrations. Works from a throwaway clone of the template (no template remote is ever added to the project). Use when the user asks to update the project to the latest ukpt.
Add or change a urpc client/server service in UKPT end-to-end — the @Urpc contract in :api, the ServiceImpl + Koin binding on :server, and (for the very first service) the Ktor host. Use when adding an @Urpc service, wiring a client↔server call, or working with the `services` axis of a feature's :api/:server modules.
Validate a web/wasm (wasmJs) client change by actually bundling (webpack) and serving it in a browser — because `compileKotlinWasmJs` only type-checks and misses bundle/runtime failures. Use when a change touches the web client, Ktor client engines, the navigation entry point, or ViewModel/Koin wiring, or whenever the web build or render needs confirming.
