shopify-admin-customer-note-bulk-annotator

Adds internal notes to customer records in bulk — useful for post-campaign flags, import annotations, or support context.

Purpose

Queries customers matching a filter (tag, email list, or spend threshold) and appends a note to each customer record. Internal notes are visible to staff in Shopify Admin but not to customers. Used for post-campaign annotation, import source tracking, VIP flags, or support context.

Prerequisites

Authenticated Shopify CLI session: shopify store auth --store --scopes read_customers,write_customers

API scopes: read_customers, write_customers

Parameters

Parameter	Type	Required	Default	Description
store	string	yes	—	Store domain (e.g., mystore.myshopify.com)
filter	string	yes	—	Customer filter query (e.g., `tag:vip`, `total_spent:>=500`)
note	string	yes	—	Note text to append to matching customers
append	bool	no	true	Append to existing note (true) or replace entirely (false)
dry_run	bool	no	true	Preview matching customers without executing mutations
format	string	no	human	Output format: `human` or `json`

Safety

> ⚠️ If append: false, this overwrites the existing customer note entirely. Existing notes will be lost. Default is append: true which safely appends with a timestamp prefix. Run with dry_run: true to confirm the customer list before committing.

Workflow Steps

OPERATION: customers — query

Inputs: query: , first: 250, select id, displayName, note, pagination cursor

Expected output: Matching customers with existing notes; paginate until hasNextPage: false

Construct new note: if append: true, prepend [YYYY-MM-DD] to existing note (newline-separated); if append: false, replace with

OPERATION: customerUpdate — mutation

Inputs: id: , note:

Expected output: customer { id, note }, userErrors

GraphQL Operations

# customers:query — validated against api_version 2025-01
query CustomersByFilter($query: String!, $after: String) {
  customers(first: 250, after: $after, query: $query) {
    edges {
      node {
        id
        displayName
        defaultEmailAddress {
          emailAddress
        }
        note
        tags
      }
    }
    pageInfo {
      hasNextPage
      endCursor
    }
  }
}

# customerUpdate:mutation — validated against api_version 2025-01
mutation CustomerUpdateNote($input: CustomerInput!) {
  customerUpdate(input: $input) {
    customer {
      id
      displayName
      note
    }
    userErrors {

      message
    }
  }
}

Session Tracking

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

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Customer Note Bulk Annotator         ║
║  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>

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):

══════════════════════════════════════════════
OUTCOME SUMMARY
  Customers matched:   <n>
  Notes updated:       <n>
  Errors:              <n>
  Output:              annotation_log_<date>.csv
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "customer-note-bulk-annotator",
  "store": "<domain>",
  "started_at": "<ISO8601>",
  "dry_run": true,
  "filter": "<query>",
  "note": "<text>",
  "append": true,
  "outcome": {
    "matched": 0,
    "updated": 0,
    "errors": 0,
    "output_file": "annotation_log_<date>.csv"
  }
}

Output Format

CSV file annotation_log_.csv with columns:

customer_id, name, email, previous_note, new_note

Error Handling

Error	Cause	Recovery
`THROTTLED`	API rate limit exceeded	Wait 2 seconds, retry up to 3 times
`userErrors` on customerUpdate	Invalid input or read-only customer	Log error, skip customer, continue
No customers match filter	Filter too narrow	Exit with 0 matches

Best Practices

Always use append: true unless you explicitly intend to overwrite existing notes — staff notes may contain important history.

Include a datestamp in the note text itself (e.g., "2026-04-11: Campaign X participant") so notes remain interpretable months later.

Use dry_run: true to confirm the customer count before annotating — a broad filter can match thousands of customers unexpectedly.

For import-source tracking, annotate immediately after the import run to maintain a clear audit trail.
