IAP Finalizer

Finish a one-time in-app purchase on the store side: price + localization, the two fields the asc-metadata MCP can't set (it exposes only reference name / review note / family-sharing). Moves an IAP from MISSING_METADATA → READY_TO_SUBMIT so it can ship with the build.

> This finalizes; it does not define. The product id, tier, and price decision come from Phase 4 (Monetization / StoreKit). The ASC IAP record must already exist (created via the MCP create_iap or the ASC UI). This skill sets the metadata on that existing record.

Where it fits (read the seams)

• Not Phase 4. Phase 4 builds the IAP into the app (StoreKit 2, paywall) and decides the price. This is Phase 6 store-metadata finalization.
• Price = one source of truth. Do not re-ask the price. Read it from the monetization decision in .planning/ (e.g. MONETIZATION.md / PLAN.md); only confirm it. Re-eliciting risks drift from the paywall/StoreKit price.
• Not promoted-iap. That generator displays promoted IAPs in-app; this sets ASC price/localization. Different jobs.
• One-time IAPs only. Subscriptions are a separate ASC flow (groups/offers) — out of scope here.

Prerequisites

• _shared/asc-api/ set up (see its README — key + ~/.appstoreconnect/).
• Set ASC="python3 <path to asc.py>". asc.py lives at _shared/asc-api/asc.py under the same skills/ root as this skill — resolve it relative to this SKILL.md file's location (../../_shared/asc-api/asc.py from this skill's directory), never relative to the project cwd (skills run with cwd = the user's project). Known install locations:
• SwiftShip symlink install: ~/.claude/swiftship-skills/_shared/asc-api/asc.py
• Copied install: .claude/skills/_shared/asc-api/asc.py (project) or ~/.claude/skills/_shared/asc-api/asc.py (global)
• Plugin install: resolve from this file's location — the _shared/ tree ships with the plugin.
• The IAP already exists in ASC. Get its id with the MCP: list_iap → pick the product.
• Price decided in Phase 4. Read it from .planning/ and confirm — don't invent it.

Flow — dry-run → confirm → apply

1. Confirm state. MCP get_iap → current state + productId. Read the target price + Display Name (≤30) + Description (≤45) from .planning/; confirm with the user via AskUserQuestion if anything is missing.
2. Find the price point.

   $ASC GET "/v1/inAppPurchases/<IAP_ID>/pricePoints?filter[territory]=USA"

Pick the inAppPurchasePricePoint id whose customerPrice matches the target tier (e.g. 6.99).

1. Set the price (one-time IAPs use price schedules):

   $ASC POST /v1/inAppPurchasePriceSchedules @price.json          # dry-run: review the body
   $ASC POST /v1/inAppPurchasePriceSchedules @price.json --apply  # after you confirm

Body: data relationships inAppPurchase→{IAP_ID}, baseTerritory→USA, manualPrices→[new inAppPurchasePrices]; included a new inAppPurchasePrices referencing the price point with startDate: null (="now").

1. Set the localization:

   $ASC POST /v1/inAppPurchaseLocalizations '{"data":{"type":"inAppPurchaseLocalizations","attributes":{"locale":"en-US","name":"<=30","description":"<=45"},"relationships":{"inAppPurchase":{"data":{"type":"inAppPurchases","id":"<IAP_ID>"}}}}}' --apply

PATCH the existing localization id instead if one already exists.

1. Review screenshot (optional): POST /v1/inAppPurchaseAppStoreReviewScreenshots — the 3-step ASC upload (reserve → upload bytes → commit).
2. Verify: MCP get_iap → state no longer MISSING_METADATA.

Done

• IAP priced + localized in ASC; state advanced; ready to submit with the build.

Caveats

• Verify each endpoint/field against the current ASC API reference before --apply (captured 2026-07).
• Every write is dry-run first — show the body, confirm, then --apply. Never --apply a price the user hasn't seen.
• One-time IAPs only. Subscriptions → the MCP create_subscription* tools + a separate flow.
