MedAssist-ng - AI Coding Instructions

Purpose

Use AGENTS.md as the canonical governance source. Read the referenced skill files before starting any task.

Product: MedAssist-ng is a medication planner with stock tracking, reminders (email/push), refill history, and schedule sharing.
Tech stack: React + TypeScript + Vite (frontend/), Fastify + TypeScript + Drizzle + SQLite (backend/).
Request path: Frontend uses /api/* only; backend route handlers live in backend/src/routes/.
Primary backend modules:
- Auth/SSO: backend/src/routes/auth.ts, backend/src/routes/oidc.ts, backend/src/plugins/auth.ts
- Medications/data: backend/src/routes/medications.ts, backend/src/db/schema.ts
- Reminders: backend/src/services/reminder-scheduler.ts, backend/src/routes/planner.ts, backend/src/routes/settings.ts
Primary frontend modules:
- Pages: frontend/src/pages/
- Shared app state: frontend/src/context/AppContext.tsx
- Domain hooks: frontend/src/hooks/
- Translations: frontend/src/i18n/en.json, frontend/src/i18n/de.json

Use this orientation for quick navigation before applying the rules below.

English only for project artifacts.
NEVER run remote git commands — no git push, no gh pr create/merge, no gh release, no git tag. Prepare locally, then hand off to @release-manager.
Testing work belongs to @testing-manager.
PR/release/CI orchestration belongs to @release-manager.
Keep changes local, focused, and consistent with existing UI/API patterns.
Remove obsolete code when re-implementing — never leave dead code behind.
Document behavioral discoveries: When you discover or clarify how a feature works (e.g., what triggers notifications, how thresholds interact, which code paths exist), always add or update the relevant section in doku/APP_BEHAVIOR.md. This is mandatory — do not rely on conversation context alone.

Frontend calls backend through /api/*.
DB changes must stay backward-compatible (schema default + alter migration + null-safe reads).

Before starting any task, identify which skills apply and read their full SKILL.md file for detailed rules.

Desktop + Mobile Parity: Medication edit has two paths — MedicationsPage.tsx (desktop) and MobileEditModal (mobile). Always update BOTH.
Notification Dual Code Paths: Notifications have two code paths — backend/src/services/reminder-scheduler.ts (scheduler) and backend/src/routes/planner.ts (manual). Always update BOTH.

Testing handoff → @testing-manager: test planning, writing, execution, CI test triage.
Release handoff → @release-manager: PR/release orchestration, merge flow, workflow monitoring.
