Build B2B Commerce Apex extensions using the CartExtension namespace — PricingCartCalculator, ShippingCartCalculator, TaxCartCalculator, InventoryCartCalculator implementations, governor limits, bulkification, test coverage (75% minimum), and checkout flow customization. Use when implementing server-side B2B commerce logic.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Salesforce B2B Commerce Apex Extensions (CartExtension Namespace)

## Before Writing Code

**ALWAYS fetch live documentation BEFORE writing any Apex code:**

1. Web-search: "Salesforce B2B Commerce Apex developer guide 2026"
2. Web-search: "Salesforce B2B Commerce checkout integration Spring 2026"
3. Web-fetch official Salesforce documentation for:
   - B2B Commerce ConnectApi namespace reference
   - CartExtension namespace and AbstractCartCalculator class
   - Apex governor limits (latest release notes)
   - Test class requirements and best practices
4. Web-fetch: `https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/`
5. Web-fetch: `https://developer.salesforce.com/docs/commerce/salesforce-commerce/overview`

**Why this matters:** Salesforce releases three times per year (Spring, Summer, Winter). Commerce APIs, CartExtension interfaces, and governor limits change. Live docs prevent using deprecated patterns.

How to install

The exact contents, by fingerprint

mdr add orcaqubits/agentic-commerce-skills-plugins/sf-b2b-apex@sha256:af395e100c437594

The line at the top of this page pins the label git:20260914.08f85a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
