Extracts multi-step business rules from Express handlers into app/src/domain/<area>/ modules: DomainFailure + typed API error codes (no HTTP), success metadata only, reload/events at transports. Use when adding or refactoring domain functions (e.g. placeBet), migrating a fat v2 route or web handler, splitting integration tests between domain and HTTP, or deciding where eventsManager.emit and getById reload belong.
Prefer Zod for runtime validation of env vars, HTTP inputs, and parsed external data. Instructs checking the installed library version (e.g. Zod 3 vs 4) and matching official docs and examples to that version so APIs are not outdated or deprecated. Covers ndb2 shared validation layout (@shared/validation/domain vs http, route-local composition). Use when adding validation, parsing request bodies or query strings, validating environment configuration, or refactoring manual checks into schemas.
NDB2 web rendering with @kitajs/html: PascalCase Kitajs components, kebab-case component files in one folder per component (name/name.tsx, name.css, name.test.tsx, index.ts), feature folders (page.tsx, handler.tsx, tests/), HTMX. Query parsing uses @shared/validation/http + domain and colocated parse/serialize helpers; see skill body. Component props: use dot access (props.title) only; do not destructure the props object at the start of a component (no const { x } = props) except the documented rest-and-forward pattern — see Component props. Prefer narrow local props interfaces (no Entities.* in markup); see Props types. mergeClass, Suspense + renderToStream. Use when adding or changing server-rendered UI under app/src/web; not for React client apps or EJS. Triggers: PreferencesForm, Button, PageLayout, props, destructuring.

All files under app/src/domain/ use kebab-case names, including test suffixes:
season-manager.ts, season-manager.test.ts, season-manager.integration.test.tsdiscord-gateway.ts, prediction-monitor.tsevents-manager.ts, monitor-runner.ts, with-pool-client.tsImports use the same stem as the file (via @domain/... or relative paths):
@domain/events/events-manager@domain/seasons/season-managerSymbols inside files stay idiomatic TypeScript (eventsManager, SeasonManager, MonitorRunner classes, etc.); only filenames are kebab-case.
Subfolders stay lowercase single words where they already are (discord/, events/, monitors/, predictions/, seasons/, webhooks/).
For what belongs inside domain modules (orchestration vs HTTP), see domain-operations.
Naming collision: @shared/validation/domain (wire Zod snippets in app/src/shared/validation/domain.ts) is unrelated to app/src/domain/ (product domain code). Prefer @domain/... for the latter.
