worth-building

Decide how elaborate to build something (simple vs. robust) and return a concrete, PoC-shaped proposal at that level — not over- or under-engineered, but right-sized. Use whenever someone is building something and the investment level is unclear: "quick or proper?", "MVP vs. real product", "is this over-engineering?", "how should I approach X?", "quick script vs. robust system", "how much architecture?", "how much do I build here?". Fires even without "poc" or "right-size" — any time effort and complexity of what to build are being weighed.
