Framework-Hooks Performance Documentation

Performance Philosophy

Why Performance is Critical for User Experience

Performance in the Framework-Hooks system directly impacts every aspect of the Claude Code SuperClaude experience. Unlike traditional batch processing systems, hooks execute in the critical path of user interaction, making sub-perceptible execution times essential for maintaining natural workflow.

Core Performance Principles:

  1. Zero Perceived Latency: All hook operations must complete within human perception thresholds to maintain seamless interaction flow
  2. Progressive Enhancement: Performance improvements should enhance intelligence without degrading baseline functionality
  3. Resource Awareness: Adaptive behavior based on system resource availability and constraints
  4. Evidence-Based Optimization: All performance improvements validated through measurable metrics and user experience data

Performance Impact Chain:

Hook Performance → Session Responsiveness → User Productivity → Framework Adoption

User Experience Thresholds:

  • <50ms: Imperceptible delay - optimal user experience
  • 50-100ms: Barely perceptible - acceptable for complex operations
  • 100-200ms: Noticeable but tolerable - requires justification through value
  • 200ms+: Disruptive to workflow - triggers performance fallbacks
