+# GUIDE COMPLET — Prompts Cursor
+# App Marchand de Biens — Expo + PocketBase
+
+---
+
+## PROMPT 1 — Fondation (Setup + Auth + Navigation)
+
+Lis .cursorrules et AGENTS.md.
+
+Je crée une app React Native Expo pour marchand de biens immobiliers.
+Backend : PocketBase sur http://localhost:8090 (déjà lancé, collections déjà créées).
+
+Collections existantes dans PocketBase :
+users, etapes_pipeline, contacts, biens, analyses_financieres,
+visites, taches, notes_biens, documents_biens, devis_travaux
+
+PARTIE A — Initialisation :
+Dans le dossier actuel, initialise l'app Expo :
+  npx create-expo-app@latest app --template tabs
+  cd app
+
+Installe ces dépendances dans app/ :
+  pocketbase
+  @tanstack/react-query
+  zustand
+  nativewind
+  tailwindcss
+  @react-native-async-storage/async-storage
+  expo-image-picker
+  expo-document-picker
+  expo-haptics
+
+PARTIE B — Fichier .env.local à la racine de app/ :
+  EXPO_PUBLIC_PB_URL=http://localhost:8090
+
+PARTIE C — Service PocketBase app/services/pocketbase.ts :
+  - Client singleton PocketBase
+  - Persistance session avec AsyncStorage
+  - Export : pb, getCurrentUserId(), isAuthenticated()
+
+PARTIE D — Types TypeScript app/types/collections.ts :
+  Interfaces pour toutes les collections (étendent RecordModel de pocketbase) :
+  UserRecord, BienRecord, ContactRecord, VisiteRecord, TacheRecord,
+  EtapePipelineRecord, AnalyseFinanciereRecord, NoteRecord, DocumentRecord, DevisRecord
+  + types BienCreate, BienUpdate (Omit + Partial)
+
+PARTIE E — Constantes app/constants/metier.ts :
+  ETAPES_DEFAUT (9 étapes avec couleurs)
+  CATEGORIES_CONTACTS avec labels français
+  TYPES_BIENS avec labels français
+  AVIS_VISITE avec labels et couleurs
+
+PARTIE F — Auth :
+  app/context/AuthContext.tsx : login, logout, user courant, redirect auto
+  app/app/auth/login.tsx : email + password, couleur primaire #1D4ED8
+  app/app/auth/register.tsx : email, password, nom, prénom
+
+PARTIE G — Navigation :
+  5 onglets dans app/app/(tabs)/ :
+  - index.tsx → Dashboard (icône grid)
+  - biens.tsx → Biens (icône home)
+  - visites.tsx → Visites (icône clipboard)
+  - contacts.tsx → Contacts (icône people)
+  - agenda.tsx → Agenda (icône calendar)
+
+  Écrans de détail :
+  - app/bien/[id].tsx
+  - app/bien/nouveau.tsx
+  - app/contact/[id].tsx
+  - app/visite/[id].tsx
+  - app/calculateur/[bienId].tsx
+
+  Chaque écran de détail = placeholder avec titre pour l'instant.
+  FAB "+" sur les onglets Biens et Contacts.
+
+L'app doit se lancer avec : cd app && npx expo start
+L'auth doit fonctionner avec un compte créé sur PocketBase.
+Mets à jour AGENTS.md quand c'est terminé.
+
+---
+
+## PROMPT 2 — Pipeline + Fiche Bien + Calculateur
+## Lancer SEULEMENT après que le Prompt 1 tourne
+
+Lis .cursorrules et AGENTS.md.
+L'auth et la navigation fonctionnent. Je construis le cœur de l'app.
+
+HOOK app/hooks/useEtapes.ts :
+- fetchEtapes() : étapes du user triées par ordre

+Bouton "Générer rapport IA" → pb.send('/api/generate-rapport') → affiche markdown
+
+Hook serveur pocketbase/pb_hooks/generate_rapport.pb.js :
+routerAdd("POST", "/api/generate-rapport", (c) => {
+  const info = $apis.requestInfo(c);
+  if (!info.authRecord) return c.json(401, {error: "Non autorisé"});
+  const { notes_brutes, checklist_reponses, bien_info } = info.data;
