Key concepts

  • Genie framework: the analogy for context window management; the AI grants the wish you describe, not the one you intended
  • PRD-driven development: using planning documents (masterplan.md, implementation.md, design-guidelines.md, user-journey.md, tasks.md) to give the agent persistent context across sessions
  • Four parallel builds: starting five simultaneous projects with varying levels of specificity to converge on the right design direction without committing tokens to refinement
  • Four-by-four debugging: a four-step unblocking sequence (try-to-fix → console logging → external diagnostic → revert and re-prompt)
