# Economics Gathers the cost/price assumptions needed to evaluate a candidate's unit economics, then hands them to `hunt economics-set`, which runs the real, tested `engine.economics.calculator`/`stress_test` code. **This Skill never performs the margin/cash-margin/ROI/breakeven arithmetic itself, in any form** — not as a rough estimate, not as a sanity check, not as a preview before calling the CLI. Every number reported to the human is a direct readout of what `economics-set`/`economics-show` returned. Full formulas, thresholds, and edge-case rules live in `references/economics.md` — read it before using this Skill if any of the below is unclear. ## When to use this Any time from `ECONOMICS_CHECK` state onward, whenever cost/price assumptions are available or need to be gathered. Can be re-run any time assumptions change (e.g. a supplier quote updates) — `economics-set` is an upsert, not append-only (`references/economics.md` ECON-10). ## Step 1 — Check what's already recorded Before asking the human anything, run: ``` hunt economics-show <opportunity_id> ``` If this shows `NOT_PROVIDED` / "none supplied yet," nothing is recorded. If it shows a prior result, decide with the human whether it's still current before re-collecting inputs (see `time-budget-controller.md` Rule 2 — don't re-ask for information already on file without reason). ## Step 2 — Gather the required inputs Four fields are **required** for any result at all (ECON-01): - `selling_price` - `unit_cos
