Use when adding or editing a section in the in-app help system (mobile Settings → Help). Coordinates 3 places — user_docs markdown, scripts/generate-help-content.js SECTIONS, and src/help/sections.ts — then regenerates content.ts. NEVER edit apps/mobile/src/help/content.ts manually.
Use when creating a NEW NestJS module under apps/api/src/modules/. Sets up the canonical structure (module/controller/service/dto), wires JwtAuthGuard + AccountContextGuard, enforces the (accountId, userId, dto) service signature, and registers the module with AppModule.
Use at the END of every coding task to create an ABA-{N} GitHub issue and update CLAUDE.md + user_docs/. Required even for small or internal changes. Triggers when work is "done" — before stopping, before committing PRs.
Use when adding, renaming, or removing i18n keys in the mobile app. Ensures all 8 locale files (en/de/es/fr/pl/ru/ua/be) stay in sync. Triggers on any change to apps/mobile/src/i18n/locales/.
