domain-operations

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.

input-validation

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the installed library version (e.g. Zod 3 vs 4) and matching official docs and examples to that version so APIs are not outdated or deprecated.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.

kitajs-html-web

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.

description	Requires kebab-case filenames for modules under app/src/domain. Use when adding, renaming, or importing files in app/src/domain, or when a PR touches domain layout or @domain/* path aliases.

Domain module filenames (kebab-case)

All files under app/src/domain/ use kebab-case names, including test suffixes:

season-manager.ts, season-manager.test.ts, season-manager.integration.test.ts
discord-gateway.ts, prediction-monitor.ts
events-manager.ts, monitor-runner.ts, with-pool-client.ts

Imports use the same stem as the file (via @domain/... or relative paths):

@domain/events/events-manager
@domain/seasons/season-manager

Symbols 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.
