namespace-scopes

A code-organization rule for splitting functions in one namespace into customer, store, and admin scopes.

In plain words
What is it for?
Use it when arranging TypeScript namespace files, adding a central context-based function mapping, and exporting each scope's functions.
Why use it?
It keeps unrelated functions separated and prevents scope files from depending directly on one another.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

namespace-scopes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Splitting Namespace Functions into Scopes

This rule defines how to organize functionality in a namespace by scope.

Structure

  1. Split functionality into three scopes:

    • customer - Functions related to customer operations
    • store - Functions related to store operations
    • admin - Functions related to admin operations
  2. Create separate files for each scope:

    • customer.functions.ts - Customer-related functions
    • store.functions.ts - Store-related functions
    • admin.functions.ts - Admin-related functions
  3. Create a main functions file (e.g., functions.ts) that:

    • Imports all scope files
    • Exports a context mapping function (contextTo<namespace>FunctionMapping)

Implementation Rules

  1. No cross-imports: Do not import between scope files (customer/store/admin)
  2. Context mapping: Create a mapping function that determines which function to use based on context parameters
  3. Exports: Export all functions through the main functions file

Example (Order namespace)

In functions.ts:

import * as customer from './customer.functions';
import * as admin from './admin.functions';
import * as store from './store.functions';

export const contextToOrderFunctionMapping = ({
  customerId,
  storeKey,
}: {
  customerId?: string;
  storeKey?: string;
}): Record<string, Function> => {
  if (customerId) {
    return {
      read_order: customer.readCustomerOrder,
    };
  }
  if (storeKey) {
    return {
      read_order: store.readStoreOrder,
      create_order_from_cart: store.createOrderFromCartInStore,
      create_order_from_quote: store.createOrderFromQuoteInStore,
      update_order: store.updateOrderByIdInStore,
    };
  }
  return {
    read_order: admin.readOrder,
    create_order_from_cart: admin.createOrderFromCart,
    create_order_from_quote: admin.createOrderFromQuote,
    create_order_by_import: admin.createOrderByImport,
    update_order: admin.updateOrder,
  };
};

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

namespace-scopes is a cursor rule published in the GitHub repository commercetools/mcp-essentials (13 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 459 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
