A comprehensive guide detailing three scalable architecture patterns for integrating applications with HubSpot CRM. It helps developers choose the optimal design based on project scale, ranging from simple embedded clients for MVPs, to robust Service Layers with caching and async queues, up to dedicated, enterprise-grade API Gateways for multiple services. Essential for planning complex, high-volume integrations.

Manages data privacy compliance for HubSpot CRM, addressing global regulations like GDPR and CCPA. This tool facilitates Data Subject Access Requests (DSAR) by performing complete data exports, executing GDPR-compliant contact deletions, and implementing PII redaction for secure logging and reporting. Essential for maintaining regulatory compliance and data integrity.

This skill demonstrates how to implement robust Role-Based Access Control (RBAC) within HubSpot integrations. It covers best practices for managing permissions using OAuth scopes, configuring multiple private apps for different access levels (Reader, Writer, Admin), and implementing application-level middleware to enforce least privilege access across CRM objects.

This collection provides production-ready, idiomatic patterns for the @hubspot/api-client SDK, specifically tailored for TypeScript. It addresses critical development concerns including creating typed wrappers, implementing robust, structured error classification (handling rate limits, authentication issues, etc.), and managing efficient batch operations (create, read, upsert) for HubSpot CRM data. Use this when building scalable, reliable, and maintainable HubSpot integrations.

This comprehensive guide assists developers in upgrading the @hubspot/api-client SDK. It covers migrating between major API versions (e.g., v1 to v3, v3 to v4), addressing key breaking changes, and implementing modern authentication patterns, such as transitioning from API Keys to Access Tokens. Use this when integrating or maintaining HubSpot-dependent applications.

A comprehensive guide for developers migrating the intercom-client npm package, particularly addressing major version jumps (e.g., v5 to v6) and associated breaking changes. Learn how to update client initialization, modify contact and conversation operations, and handle API version pinning using TypeScript and modern asynchronous patterns.

Implements approved development tasks using Test-Driven Development methodology with autonomous or manual sub-agent dispatch. Supports multiple review modes (required/inline/off) and integrates with project specifications, requirements, and design documents for comprehensive implementation validation. Automatically discovers validation commands and establishes repository baselines before execution.

This utility analyzes a codebase (product, technology, and structure) to automatically extract core architectural patterns, guiding principles, and engineering standards. It manages a persistent 'Steering' repository, performing initial bootstrapping and continuous synchronization. It detects 'code drift' when the code deviates from established patterns and suggests additive updates, ensuring project documentation remains a comprehensive source of truth.

This comprehensive guide provides step-by-step instructions for deploying applications integrated with Klaviyo across major modern cloud environments, including Vercel, Fly.io, and Google Cloud Run. It covers essential DevSecOps practices, such as managing platform-specific secrets (API keys, webhook signing secrets), configuring middleware for secure webhook validation (HMAC), and implementing robust health checks to ensure a stable, production-ready deployment.

This reference architecture provides a production-ready, layered structure for integrating external applications with Klaviyo. It outlines best practices for building robust marketing automation systems, including profile synchronization (bidirectional sync), event-driven webhook handlers, background job processing, and implementing middleware like rate limiters. Use this when designing new data pipelines, reviewing project structure, or establishing standardized data synchronization standards for email/SMS campaigns.

A comprehensive index of 46 production-grade test automation skills, covering E2E, unit, mobile, BDD, and cloud testing across 15+ languages. This skill equips AI coding assistants to act as senior QA architects, generating structured, real-world test code for major frameworks like Playwright, Selenium, Cypress, and Jest. It supports project setup, CI/CD integration, and cross-platform debugging.

This guide provides advanced patterns for composing robust, multi-step Large Language Model (LLM) workflows using LangChain 1.0 core runnables. Learn to implement parallel retrievals (RunnableParallel), conditional routing (RunnableBranch), and state management. It also addresses common pitfalls like silent KeyErrors due to mismatched dictionary shapes, providing solutions using debug probes and type annotations for reliable RAG, classification, and extraction pipelines.
