shopify-admin-shipping-rate-audit

What this skill does

## Purpose
Audits the shipping configuration for every delivery profile on the store. Surfaces (a) zones with zero shipping rates configured (causing checkout failures), (b) zones with only manual flat rates (no carrier-calculated rates, often a missed setup step), and (c) profiles with no zone coverage for known sales geographies. A misconfigured zone silently drops checkout conversions — this skill catches it before customers do. Read-only — no mutations.

## Prerequisites
- Authenticated Shopify CLI session: `shopify store auth --store <domain> --scopes read_shipping`
- API scopes: `read_shipping`

## Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| profile_filter | string | no | — | Optional delivery profile name to scope the audit |
| flag_manual_only | bool | no | true | Flag zones that have only manual rates (no carrier-calculated rates) |
| flag_high_price | float | no | — | Optional: flag any rate above this price (likely typo or stale) |
| format | string | no | human | Output format: `human` or `json` |

## Safety

> ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. The skill reads delivery configuration only; it does not change any shipping behavior.

## Workflow Steps

1. **OPERATION:** `deliveryProfiles` — query
   **Inputs:** `first: 50`, select `profileLocationGroups`, `profileItems`, `name`, `default`, pagination cursor
   **Expected output:** All delivery profiles, including the default, with location groups and product associations; paginate until `hasNextPage: false`

2. For each profile, walk every `profileLocationGroups[].locationGroupZones`. For each zone, capture: zone name, country codes, method definitions (rates).

3. Flag zones with: zero `methodDefinitions`, OR only manual `priceConditions`-based rates (no carrier-calculated method when `flag_manual_only: true`), OR a method whose `price.amount > flag_high_price` if the threshold is set.

4. Aggregate findings per profile, then build a global summary of misconfigured zones across the store.

## GraphQL Operations

## Session Tracking

**Claude MUST emit the following output at each stage. This is mandatory.**

**On start**, emit:
```
╔══════════════════════════════════════════════╗
║  SKILL: Shipping Rate Audit                  ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝
```

**After each step**, emit:
```
[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>
```

**On completion**, emit:

For `format: human` (default):
```
══════════════════════════════════════════════
SHIPPING RATE AUDIT
  Profiles inspected:    <n>
  Zones inspected:       <n>
  Zones with no rates:   <n>
  Zones manual-only:     <n>
  Rates above threshold: <n>

  Critical issues (zero-rate zones):
    Profile: <name>  Zone: <name>  Countries: <list>
  Output: shipping_rate_audit_<date>.csv
══════════════════════════════════════════════
```

For `format: json`, emit:
```json
{
  "skill": "shipping-rate-audit",
  "store": "<domain>",
  "profiles_inspected": 0,
  "zones_inspected": 0,
  "zones_no_rates": 0,
  "zones_manual_only": 0,
  "rates_above_threshold": 0,
  "issues": [],
  "output_file": "shipping_rate_audit_<date>.csv"
}
```

## Output Format
CSV file `shipping_rate_audit_<YYYY-MM-DD>.csv` with columns:
`profile_name`, `zone_name`, `countries`, `rate_count`, `manual_rate_count`, `carrier_rate_count`, `min_rate`, `max_rate`, `currency`, `flag`

## Error Handling
| Error | Cause | Recovery |
|-------|-------|----------|
| `THROTTLED` | API rate limit exceeded | Wait 2 seconds, retry up to 3 times |
| Profile has no products | Empty profile | Note in output, do not flag as critical |
| Zone has only `DeliveryRateDefinition` (no carrier) | Manual rates only | Flag if `flag_manual_only: true` |
| Country list is null on a zone | Rest-of-world catch-all zone | Treat as wildcard, do not flag for missing countries |

## Best Practices
- Run after any major shipping change (new region launch, carrier switch) to confirm zone coverage matches the rollout plan.
- Zero-rate zones cause silent checkout failures — customers from that geography see "no shipping available" and abandon. Treat these as P0.
- Manual-only zones are not always wrong — flat-rate domestic shipping is a deliberate choice. Use `flag_manual_only: false` if your store is intentionally flat-rate.
- Cross-reference flagged country codes with `customers:query` filtered by country to estimate revenue at risk.
- Run quarterly to catch zones added by app integrations or staff that drift from the documented configuration.
