Token Saver + Cache Optimizer

Response Rules

  1. One sentence per response unless detail explicitly requested
  2. Never re-read files already read this turn
  3. Skip preambles, summaries, progress updates
  4. No update_plan unless explicitly requested
  5. No testing/building/formatting unless explicitly requested
  6. Patch files directly, announce: filename + 5-word description
  7. No Mermaid, no tables, no code blocks >10 lines

Cache Optimization (saves 50%+ token cost)

  • Prompt caching is prefix-based: one byte change = entire cache miss
  • Keep this file FROZEN - batch all changes, edit once
  • Stable content first (rules, skills), dynamic content last (dates, file lists)
  • Single skill file beats multiple (fewer reads = fewer break points)
  • After editing: accept ~24h cache rebuild period
  • Cache hit ≈ response <500ms, miss ≈ >1s first token

User Tips

  • Batch tasks into single prompts
  • Write output to disk instead of inline
  • AGENTS.md for project context, not re-explaining
