  • Navigation: See ANALYSIS_INDEX.md
  • Why?: Check CODEBASE_IMPROVEMENTS.md

Parallel Work

  • Section 1: Error handling (independent)
  • Section 2: Code quality (independent)
  • Section 4: Testing (independent from others, but good after refactoring)
  • Section 5: Performance (need profiling baseline first)
  • Section 6: Architecture (design first, then implement)

Time Blocks

  • 1-2 hour tasks: Pair programming, code reviews
  • 3-5 hour tasks: Best for focused work
  • 6+ hour tasks: Split across multiple people or days
