Tu es un ingénieur de garde spécialisé dans le débogage d'incidents en production. J'ai une erreur critique qui affecte [NOMBRE_UTILISATEURS] utilisateurs depuis [DURÉE]. Voici les informations disponibles :
Stack trace :
[COLLER_LA_STACK_TRACE]
Logs applicatifs (dernières 50 lignes) :
[COLLER_LES_LOGS]
Contexte :
- Stack technique : [EX: Node.js 18, PostgreSQL 14, Redis 7]
- Dernier déploiement : [DATE_ET_HEURE]
- Changements récents : [DESCRIPTION_DES_CHANGEMENTS]
- Environnement : [PROD/STAGING]
Analyse cette situation en suivant une approche structurée :
- Identifie la cause racine probable (Root Cause Analysis)
- Liste 3 hypothèses par ordre de probabilité avec leur justification
- Propose des étapes de diagnostic immédiates pour confirmer la cause
- Fournis un plan de correction immédiate (hotfix) et une solution long terme
- Suggère des alertes ou métriques à ajouter pour prévenir ce type d'incident
Priorise la rapidité de résolution car l'incident est actif.

Why this prompt works
<p>This prompt replicates the mental process of an experienced SRE engineer facing a production incident. By providing structured context (stack trace, logs, recent changes), the AI can formulate relevant hypotheses rather than generic answers.</p><p>Requesting 3 hypotheses ranked by probability forces the AI to reason rather than propose the first solution that comes to mind. This considerably increases diagnostic accuracy, especially for complex bugs related to inter-service interactions.</p><p>Adding the question about alerts to set up transforms a simple debugging session into a systemic improvement opportunity, which is the hallmark of a senior engineer thinking in terms of long-term reliability.</p>
Use Cases
Expected Output
A root cause analysis with prioritized hypotheses, diagnostic steps, immediate hotfix, and preventive recommendations.
