This tool systematically converts a project roadmap into actionable specifications. It first analyzes features by grouping them into dependency waves. It then automatically dispatches sub-agents to generate complete feature specs (requirements, design, tasks, and JSON) for each wave. The core value lies in its comprehensive cross-spec review, which verifies data model consistency, interface alignment, and architectural integrity across the entire project, ensuring a cohesive final product.

This comprehensive tool analyzes a detailed specification by synthesizing data from multiple source files (JSON, Markdown, etc.). It tracks phase completion, identifies task progress, maps boundary contexts (upstream/downstream dependencies), and proactively highlights necessary revalidation points or blockers, providing a single, unified report of the spec's completeness and current development state.

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 serves as a quick reference for diagnosing and fixing common Klaviyo API errors and SDK exceptions. It provides detailed root causes and solutions for standard HTTP status codes (400, 401, 403, 429, etc.) and common coding pitfalls. Ideal for developers integrating Klaviyo into their applications.

A comprehensive solution for managing Personally Identifiable Information (PII) and ensuring compliance with global privacy regulations like GDPR and CCPA within Klaviyo. This skill guides developers on implementing critical functions, including the 'right to erasure' (profile deletion), handling Data Subject Access Requests (DSAR) by exporting all user data, and implementing PII detection and redaction for safe logging practices. It ensures that data handling processes meet legal standards.

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.

A comprehensive, step-by-step guide for responding to Klaviyo API outages and integration failures. This runbook includes quick triage scripts, decision trees based on common error codes (401, 429, 5xx), and detailed procedures for mitigation, service degradation, and postmortem communication, ensuring rapid service recovery and operational stability.

This skill guides you through installing and setting up the official Klaviyo SDK for both Node.js and Python. It covers essential steps including authenticating with a private API key, managing environment variables for secure credential storage, and initializing resource-specific API clients (e.g., Profiles, Events). Use this when building integrations that require programmatic access to Klaviyo's marketing data, such as tracking user events or managing contact profiles.

A comprehensive deep dive guide for executing advanced Klaviyo migration strategies. Learn how to move data from legacy v1/v2 APIs, competing Email Service Providers (like Mailchimp), or execute a full platform re-platforming using patterns like the Strangler Fig. Includes technical steps for API field mapping and data transformation.

Provides advanced strategies for managing API rate limits when integrating with Klaviyo. This skill implements robust patterns like exponential backoff, respecting `Retry-After` headers, and utilizing request queuing. It ensures stable, high-throughput data synchronization, preventing 429 errors during large-scale bulk operations.

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 guide to implementing production-ready patterns for interacting with the Klaviyo API via the Node.js SDK. This includes best practices for handling singleton sessions, creating type-safe API wrappers, implementing robust retry logic for rate limits, managing cursor-based pagination, and supporting multi-tenant environments. This ensures reliable and maintainable Klaviyo integrations.
