Cross-cutting MPP development patterns — security, replay protection, HMAC challenge binding, receipt validation, error handling, retry logic, TLS requirements, and monitoring. Use when designing architecture or solving production concerns.

Implement the UCP Buyer Consent extension — GDPR/CCPA consent collection, consent fields in checkout sessions, and privacy-compliant consent management. Use when adding consent flows, privacy compliance, or data processing agreements to UCP checkout.

Run and write UCP conformance tests — validate a UCP implementation against the official test suite covering checkout lifecycle, orders, fulfillment, payments, idempotency, webhooks, and security. Use when testing or validating a UCP implementation.

Set up a UCP project — scaffold a merchant server or platform client with discovery profile, SDK installation, and project structure. Use when starting a new UCP implementation.

Implement the WebMCP provideContext API — bulk tool registration, contextual metadata, page state sharing, and dynamic context updates. Use when providing rich context and multiple tools to agents simultaneously.

Apply PHP design patterns — Singleton, Factory, Strategy, Observer, Repository, Decorator, and Dependency Injection in PHP. Use when structuring WooCommerce extension code or implementing complex business logic.

Build WooCommerce admin interfaces — settings pages, admin menus, product data tabs/panels, order meta boxes, WooCommerce Admin (React analytics), and reports. Use when creating admin-facing configuration or display pages.

Test WooCommerce extensions — PHPUnit unit/integration tests, WP test suite, WooCommerce test helpers, E2E with Playwright, and WP-CLI test scaffolding. Use when writing tests for WooCommerce plugins or setting up a test environment.

Implement MPP client-side payment handling with mppx.fetch(). Use when building AI agents or automated clients that consume 402-protected APIs, handling the transparent challenge-response payment flow.

Validate MPP implementations against the specification — verify HTTP 402 challenge-response compliance, header formats, payment method correctness, service discovery, and production readiness. Use when auditing an MPP integration or preparing for production launch.

Implement MPP service discovery — OpenAPI documents with x-payment-info extensions, x-service-info metadata, and llms.txt for autonomous agent discovery. Use when publishing paid API metadata for AI agents to find and pay for your services.

Scaffold an MPP project — install mppx SDK, configure payment methods, set up server middleware, and create a basic paid API endpoint. Use when starting a new MPP machine payments project from scratch.
