+# Playbook d'usage des agents IA (Yavsc)
+
+Ce playbook normalise l'usage de Copilot, Plan et Explore dans le depot.
+Il privilegie des sorties verifiables: fichiers, commandes tests, risques.
+
+## Quand utiliser quel agent
+
+- Plan: quand la tache est ambigue, transverse ou risquee.
+- Explore: quand il faut cartographier rapidement des zones du code.
+- Copilot: quand les specifications sont claires et localisees.
+
+## Prompt type (base)
+
+Utiliser ce squelette avant toute tache non triviale:
+
+```text
+Contexte: <projet/fichier/fonction>
+Objectif: <resultat observable>
+Contraintes: <style, archi, perimetre>
+Verification: <tests exacts a lancer>
+Sortie attendue: <fichiers modifies + risques>
+```
+
+## 4 scenarios de reference
+
+## 1) Explorer un bounded context
+
+Intention:
+- Comprendre ou implementer un changement dans un BC sans regression laterale.
+
+Prompt minimal:
+```text
+Explore le BC <nom> avec profondeur medium.
+Retour: composants touches, points d'entree, tests existants et risques.
+```
+
+Preuves attendues:
+- Carte des fichiers a modifier.
+- Test(s) smoke/mandatory proposes.
+
+## 2) Ajouter un smoke test
+
+Intention:
+- Couvrir rapidement un endpoint ou une route publique.
+
+Prompt minimal:
+```text
+Propose un smoke test pour <route/endpoint> dans le projet de test approprie.
+Respecte les conventions de doc/testing.md.
+```
+
+Preuves attendues:
+- Fichier test cree/modifie.
+- Commande precise pour executer le test cible.
+
+## 3) Corriger une regression backend API
+
+Intention:
+- Corriger un bug sans casser un flux voisin.
+
+Prompt minimal:
+```text
+Planifie puis implemente un fix de <symptome> dans <projet>.
+Ajoute/ajuste un test NonRegression rouge puis vert.
+```
+
+Preuves attendues:
+- Explication cause racine.
+- Test non-regression associe.
+- Commande d'execution et resultat attendu.
+
+## 4) Tracer un flux PostIt/OIDC
+
+Intention:
+- Localiser une cassure d'authentification entre client et serveur.
+
+Prompt minimal:
+```text
+Cartographie le flux OIDC PostIt: entrypoints, callback, stockage token,
+refresh. Donne points de rupture probables et tests/verification proposes.
+```
+
+Preuves attendues:
+- Liste ordonnee des etapes du flux.
+- Fichiers critiques.
+- Hypotheses testables.
+
+## Anti-patterns a eviter
+
+- Prompt sans objectif verifiable.
+- Demande trop large sans perimetre de fichiers.
+- Validation basee uniquement sur "ca semble correct".
+- Pas de lien entre changement et niveau de test.
+
+## Gate PR minimale (agent-assiste)
+
+Avant validation:
+- Impact architecture explicite.
+- Rationale de choix agent explicite.
+- Test(s) executes et justifies.
+- Risques residuels documentes.

+# Onboarding guide: agents IA + architecture + tests
+
+Ce guide est optimise pour accelerer la prise en main des agents IA
+(Copilot, Plan, Explore) dans Yavsc, avec une verification rapide
+par les tests.
+
+## Resultat attendu
+
+A la fin du parcours, un contributeur doit pouvoir:
+- Identifier les projets impactes par une modification.
+- Choisir l'agent adapte a l'intention de travail.
+- Produire une proposition de changement verifiable par les tests.
+
+## Parcours en 3 modules
+
+## Module A - Comprendre le terrain (30-45 min)
+
+Objectif: acquerir une lecture fiable de l'architecture.
+
+1. Lire [README.md](../README.md) puis [Architecture.md](Architecture.md).
+2. Lire [architecture/decoupage-organisation.md](architecture/decoupage-organisation.md).
+3. Selon le domaine:
+   - Backend/API: [architecture/workflow-multi-parties.md](architecture/workflow-multi-parties.md)
+   - PostIt: [architecture/postit.md](architecture/postit.md) puis [architecture/postit-oidc.md](architecture/postit-oidc.md)
+
+Definition of done:
+- Expliquer en 5 phrases quelles couches sont touchees.
+- Citer le ou les points d'entree applicatifs a verifier.
+
+## Module B - Boucle tests rapide (20-30 min)
+
+Objectif: verifier rapidement sans lancer toute la suite.
+
+1. Lire [testing.md](testing.md).
+2. Lancer les smoke tests d'abord, puis mandatory selon le projet.
+3. N'elargir au test complet que si le scope depasse le BC touche.
+
+Definition of done:
+- Fournir la commande test executee.
+- Expliquer pourquoi ce niveau de test est suffisant.
+
+## Module C - Usage agentique en production (30-40 min)
+
+Objectif: utiliser les agents comme accelerateurs, pas comme boites noires.
+
+1. Plan: decomposer la tache en etapes verifiables.
+2. Explore: collecter le contexte code/doc precise.
+3. Copilot: implementer localement et verifier.
+
+Regles:
+- Toujours donner un contexte explicite (fichier, but, contrainte).
+- Demander des preuves observables (fichiers modifies, tests, risques).
+- Refuser toute sortie non verifiable.
+
+Definition of done:
+- Une tache simple est livree avec:
+  - Plan
+  - Changement local
+  - Preuve par test
+
+## Routine continue (sans echeance fixe)
+
+Rituels recommandes:
+- Hebdo: revue des prompts qui ont bien fonctionne.
+- Mensuel: mise a jour du present guide et du playbook.
+- A chaque incident: ajouter un anti-pattern dans le playbook.
+
+## Check-list de validation
+
+- Le changement indique son impact architecture.
+- Le choix de l'agent est justifie.
+- La preuve test est incluse.
+- Les risques residuels sont explicitement listes.
