SEED

plan.json is plain data — write it from the brief. Default to 3 plans — a tier ladder the grid can render (e.g. free / monthly with a trial / yearly with a setup fee), each with 3–4 perks; together they exercise every price shape the UI handles (free, cadence, trial badge, fee line). Plans have no seedable images (the owner adds one per plan in the dashboard).

• type — "recurring" (default; billingCycle defaults to { "period": "MONTH", "count": 1 }), "one-time" (bills once, then ends; billingCycle: null makes it never expire), or "free" (amount forced to "0" + a per-member-lifetime purchase limit).
• price — a decimal string ("29.00"; a number is stringified). Currency is site-derived — never sent per plan.
• currency — 3-letter ISO code at the top of the plan, set only when the brief names one: a sentence about currency, or a price written with its unit (“9 dollars”, “$9”, “€20”). Do not infer it from a language, a country, or an address. The seed sets the site to it before creating anything, because prices are stored in the site currency at create time; a new site starts in the currency of the account that created it, not the business’s.
• freeTrialDays — days before the first charge (a number, up to 999), on a paid plan; the card shows “14-day free trial”. Omit for none.
• setupFee — { "name", "amount" }: one additional fee charged with the first payment, shown with the price (“+ €25.00 Registration fee”). fees is the array form (up to 5). Amounts are decimal strings in the site currency, like price. Only when the brief names a fee — never invent one.
• perks — display-only bullets on the plan card; they grant nothing by themselves.
• termsAndConditions (plain text), visibility ("PUBLIC"), buyable (true) — optional overrides. A buyable: false plan renders without a subscribe CTA (merchant-assigned).

Covering bookings services (only when bookings is also seeded)

A plan can COVER bookings services — members then book them with the membership. The link goes through the Benefit Programs API, not the plan object, keyed by the bookings seed’s service ids — so seed bookings FIRST, then pass the ids:

Unlimited coverage is the default; a limited pack (e.g. 8 sessions) instead uses "bookingsCoverage": { "serviceIds": [...], "creditAmount": 8 }. A plans-only run just omits both — coverage is skipped automatically.

Seeding is additive — never delete or overwrite existing content; ask first if a cleanup seems needed.

Supplied content

The general rules are in templates/shared/SUPPLIED-CONTENT.md. For pricing plans, each plan the user lists is one entry. Its name becomes name; a price with a billing period becomes price with type: "recurring" and the matching billingCycle; a price paid once becomes type: "one-time"; no price means type: "free"; a list of features or benefits becomes perks; the description becomes description; a trial (“first two weeks free”) becomes freeTrialDays; a one-off joining/registration/setup charge becomes setupFee. A price with no period is a question for the user.

Escape hatch — individual functions

setupPricingPlans composes exported steps — installPricingPlansApp, createPlans, attachBookingsCoverage (and its getProgramDefinition, createPoolDefinition, createBenefitItems sub-steps), plus makeCtx() — import them only for a partial re-seed.
