Argues the "perfect prompt" is a myth and prescribes a design-first, stage‑one workflow: write a Markdown spec as external memory, use Cursor/Claude Code planning mode and downloadable skills to produce a reviewable development plan, then run subtasks and review diffs. Demonstrates replacing a scattered --fusa flag with a generic policy mechanism in an automotive image builder, shows using sub-agents, focused compaction (slash compact), and promotes decisions into docs rather than letting context drift.
