Managing Cache and Optimization

Overview

Shannon CLI provides automatic caching and cost optimization across all operations.

Cache Management

Check statistics:

shannon cache stats

Shows: Hit rate, size, savings (USD and time)

Clear cache:

shannon cache clear         # All caches
shannon cache clear --type analysis  # Just analysis cache

Cache layers (3 tiers):

  • Analysis: 7-day TTL
  • Command: 30-day TTL
  • MCP: Indefinite

Performance targets:

  • Hit rate: >60% (good), >80% (excellent)
  • Cache speed: <500ms
  • Size: <500MB total

Cost Optimization

Set budget:

shannon budget set 10.00  # $10 limit
shannon budget status     # Check spending

Automatic model selection:

  • Simple tasks → haiku (cheapest)
  • Complex tasks → sonnet (balanced)
  • Auto-selected per complexity

View optimization:

shannon optimize

Shows: Potential savings, model recommendations

When to Clear Cache

  • After Shannon Framework updates
  • Cache size >400MB
  • Hit rate <40% (stale entries)
  • Debugging cache-related issues
