Tools of Acorn Harness
	Description		Read-only	Idempotent	Open world
`create_order`Create an unpaid order for one or more wire harness designs and get a checkout_url on acornharness.com for the buyer. The buyer opens it to pay (card, Link or wallet, via Stripe) and enter the shipping address (in the ship_to country) and, in the US, the shipping speed (other countries have one service, International Tracked); nothing is charged or built until they pay there, and the link expires after 24 hours. Quote first with quote_harness and confirm the design, quantity and price with the user before calling this. Never ask for or accept card numbers or other payment details in the conversation. Items take the same fields as quote_harness and must be just as complete: pass back each quoted item's config (or design) once the user has confirmed it, and the same ship_to.

`list_options`List every option for an Acorn Harness custom wire harness: connector types (XT30, XT30(2+2), XT30 + JST GH), wire length range, power gauges, end A and end B terminations (straight, right angle up/down, unterminated tinned leads on end B), wire colors, extras (twisted or crossed signal pair, JST GH end B), the rules for combining them, required_choices (with the question to ask the user for each), optional_choices and their defaults, pricing rules, lead time, shipping and returns. Call it when you need the allowed values; it takes no arguments and changes nothing.

`quote_harness`Price one or more custom wire harness designs exactly as acornharness.com checkout will. Returns, for each design, a picture (side view plus both ends' rear views, as the configurator draws it: show it to the user), a configurator_url that opens the design on the site, and defaults_applied. Every item needs connector, length_mm, power_gauge, end_a, end_b, quantity, or a complete design code / configurator URL in design. Items missing any of them are refused with the questions to ask: ask the user, don't guess, and ask about end A and end B separately. Colors, twisting, crossing and end_b_gh have defaults, listed in defaults_applied for you to tell the user. Volume discounts count every harness across all items. Also returns the shipping options and prices to ship_to (the US if omitted; ask the user where it ships). Prices exclude shipping (chosen at checkout from those options) and sales tax; outside the US the buyer pays import duties and taxes on delivery. Nothing is ordered or saved.
