# asc RevenueCat catalog sync

Use this skill to keep App Store Connect (ASC) and RevenueCat aligned, including creating missing ASC items and mapping them to RevenueCat resources.

## When to use
- You want to bootstrap RevenueCat from an existing ASC catalog.
- You want to create missing ASC subscriptions/IAPs, then map them into RevenueCat.
- You need a drift audit before release.
- You want deterministic product mapping based on identifiers.

## Preconditions
- `asc` authentication is configured (`asc auth login` or `ASC_*` env vars).
- RevenueCat MCP server is configured and authenticated.
- In Cursor and VS Code, OAuth auth is available for RevenueCat MCP. API key auth is also supported.
- You know:
  - ASC app ID (`APP_ID`)
  - RevenueCat `project_id`
  - target RevenueCat app type (`app_store` or `mac_app_store`) and bundle ID for create flows
- Use a write-enabled RevenueCat API v2 key when applying changes.

## Safety defaults
- Start in **audit mode** (read-only).
- Require explicit confirmation before writes.
- Never delete resources in this workflow.
- Continue on per-item failures and report all failures at the end.

## Canonical identifiers
- Primary cross-system key: ASC `productId` == RevenueCat `store_identifier`.
- Keep `productId` stable once products are live.
- Do not use display names as unique identifiers.

## Scope boundary
- RevenueCat MCP configures RevenueCat resources; it does not create App Store Connect products directly.
- Use `asc` commands to create missing ASC subscription groups, subscriptions, and IAPs before RevenueCat mapping.

## Modes

### 1) Audit mode (default)
1. Read ASC source catalog.
2. Read RevenueCat target catalog.
3. Build a diff with actions:
   - missing in ASC
   - missing in RevenueCat
   - mapping conflicts (identifier/type/app mismatch)
4. Present a plan and wait for confirmation.

### 2) Apply mode (explicit)
Execute approved actions in this order:
1. Ensure ASC groups/subscriptions/IAP exist.
2. Ensure RevenueCat app/products exist.
3. Ensure entitlements and product attachments.
4. Ensure offerings/packages and package attachments.
5. Verify and print a final reconciliation summary.

## Step-by-step workflow

### Step A - Read current ASC catalog

```bash
asc subscriptions groups list --app "APP_ID" --paginate --output json
asc iap list --app "APP_ID" --paginate --output json
# for each subscription group:
asc subscriptions list --group "GROUP_ID" --paginate --output json
```

### Step B - Read current RevenueCat catalog (MCP)

Use these MCP tools (with `project_id` and pagination where applicable):
- `mcp_RC_get_project`
- `mcp_RC_list_apps`
- `mcp_RC_list_products`
- `mcp_RC_list_entitlements`
- `mcp_RC_list_offerings`
- `mcp_RC_list_packages`

### Step C - Build mapping plan

Map ASC product types to RevenueCat product types:
- ASC subscription -> RevenueCat `subscription`
- ASC IAP `CONSUMABLE` -> RevenueCat `consumable`
- ASC IAP `NON_CONSUMABLE` -> RevenueCat `non_consumable`
- ASC IAP `NON_RENEWING_SUBSCRIPTION` -> RevenueCat `non_renewing_subscription`

Suggested entitlement policy:
- subscriptions: one entitlement per subscription group (or explicit map provided by user)
- non-consumable IAP: one entitlement per product
- consumable IAP: no entitlement by default unless user asks

### Step D - Ensure missing ASC items (if requested)

Create missing ASC resources first, then re-read ASC to capture canonical IDs.

```bash
# create subscription group
asc subscriptions groups create --app "APP_ID" --reference-name "Premium"

# create subscription
asc subscriptions create \
  --group "GROUP_ID" \
  --ref-name "Monthly" \
  --product-id "com.example.premium.monthly" \
  --subscription-period ONE_MONTH

# create iap
asc iap create \
  --app "APP_ID" \
  --type NON_CONSUMABLE \
  --ref-name "Lifetime" \
  --product-id "com.example.lifetime"
```

### Step E - Ensure RevenueCat app and products

Use MCP:
- create app if missing: `mcp_RC_create_app`
- create products: `mcp_RC_create_product`
  - `store_identifier` = ASC `productId`
  - `app_id` = RevenueCat app ID
  - `type` from mapping above

### Step F - Ensure entitlements and attachments

Use MCP:
- list/create entitlements: `mcp_RC_list_entitlements`, `mcp_RC_create_entitlement`
- attach products: `mcp_RC_attach_products_to_entitlement`
- verify attachments: `mcp_RC_get_products_from_entitlement`

### Step G - Ensure offerings and packages (optional)

Use MCP:
- list/create/update offerings:
  - `mcp_RC_list_offerings`
  - `mcp_RC_create_offering`
  - `mcp_RC_update_offering` (`is_current=true` only if requested)
- list/create packages:
  - `mcp_RC_list_packages`
  - `mcp_RC_create_package`
- attach products to packages:
  - `mcp_RC_attach_products_to_package` with `eligibility_criteria: "all"`

Recommended package keys:
- `ONE_WEEK` -> `$rc_weekly`
- `ONE_MONTH` -> `$rc_monthly`
- `TWO_MONTHS` -> `$rc_two_month`
- `THREE_MONTHS` -> `$rc_three_month`
- `SIX_MONTHS` -> `$rc_six_month`
- `ONE_YEAR` -> `$rc_annual`
- lifetime IAP -> `$rc_lifetime`
- custom -> `$rc_custom_<name>`

## Expected output format

Return a final summary with:
- ASC created counts (groups/subscriptions/IAP)
- RevenueCat created counts (apps/products/entitlements/offerings/packages)
- attachment counts (entitlement-products, package-products)
- skipped existing items
- failed items with actionable errors

Example:

```text
ASC: created groups=1 subscriptions=2 iap=1, skipped=14, failed=0
RC: created apps=0 products=3 entitlements=2 offerings=1 packages=2, skipped=27, failed=1
Attachments: entitlement_products=3 package_products=2
Failures:
- com.example.premium.annual: duplicate store_identifier exists on another RC app
```

## Agent behavior
- Always run audit first, even in apply mode.
- Ask for confirmation before create/update operations.
- Match by `store_identifier` first.
- Use full pagination (`--paginate` for ASC, `starting_after` for RevenueCat tools).
- Continue processing after per-item failures and report all failures together.
- Never auto-delete ASC or RevenueCat resources in this skill.

## Common pitfalls
- Wrong RevenueCat `project_id` or app ID.
- Creating RC products under the wrong platform app.
- Accidentally assigning consumables to entitlements.
- Skipping the post-create ASC re-read step.
- Missing offering/package verification after product creation.
