WHY57 service · public research and Skills

Help more buyers find the singles your shop already has.

WHY57 helps card shops make existing singles discoverable online without losing control of the inventory, systems, and staff workflow behind the counter. The Magic the Gathering Cookbook is the public research and reusable Skill work behind that service.

Inventory visibilityFor Stores

I want new buyers to find inventory I already have

A card can be in a case, a POS, or a spreadsheet and still be invisible to someone searching online. Map the inventory, source of truth, and safe path to publish it.

Good for
Card shops with singles and systems worth keeping, but no credible path from current inventory to online discovery.

I want to see price-aware deck research

AI turns a Commander brief into a legal deck, then checks eligible CardTrader listings so the price tradeoffs are visible before anyone buys.

Good for
Anyone who wants to inspect the recipes, price scans, purchased batches, and the method behind them.

Reusable workflowClaude Code + Codex

I want to build this kind of setup

See how a Skill bundles the instructions, references, scripts, and action boundaries an agent needs to do the same job again.

Good for
