🎯 Overview

This document defines the complete failure handling strategy for Symphony extensions across all possible scenarios. Every failure path is mapped to a specific response strategy, ensuring predictable and reliable behavior under all conditions.

📊 Extension Classification System

Priority Levels

• 🔴 Essential: Workflow cannot complete without these models
• 🟡 Recommended: Quality degraded but workflow can continue
• 🟢 Optional: No impact on core workflow success

Position in Workflow

• 🚀 First: Entry point models (prompt enhancers, requirement analyzers)
• 🏗️ Mid-Level: Core processing models (code generators, planners)
• 🎯 Final: Output models (formatters, documenters, packagers)

Dependency Types

• 🔗 Sequential: Must complete before next step
• 🌿 Parallel: Can run concurrently with others
• 🔄 Iterative: May be called multiple times
