A comprehensive guide for diagnosing and fixing common HubSpot API errors (e.g., 401, 403, 429, 400). It provides real error response bodies, root cause analysis, and actionable code solutions for debugging failed API requests, improving integration reliability, and managing complex CRM interactions.

This structured skill guides users through root-cause-first debugging when an implementer is blocked, verification fails, or repeated attempts at fixing do not converge. It mandates a systematic approach combining local evidence inspection, runtime analysis, and external documentation research to accurately classify the failure's true source (e.g., missing dependency, spec conflict). It prevents speculative patching and generates a clear, actionable fix plan.

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 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.

A comprehensive guide to ensuring robust state management for LangGraph agents. This skill addresses common checkpointing pitfalls (like missing thread_id or non-JSON serializable state) and details best practices for implementing reliable state persistence using MemorySaver or PostgresSaver. It covers thread discipline, schema migration, and time-travel debugging for production-ready applications.

A comprehensive guide to advanced, production-ready LLM inference using LangChain 1.0. This skill addresses common pitfalls and bugs when integrating multiple providers (Claude, GPT-4o, Gemini), covering issues like structured output reliability, correct streaming token accounting, and robust handling of complex AIMessage content blocks. It teaches best practices for model initialization, provider routing, and version-safe code implementation.

This comprehensive guide details common errors encountered when integrating with the Linktree API. It covers various HTTP status codes, such as 400 (Invalid URL), 401 (Authentication Failed), and 429 (Rate Limit). The document provides specific causes (e.g., expired keys, malformed data, plan restrictions) and actionable fixes, helping developers build stable and reliable link-in-bio services.

This comprehensive debug bundle collects all necessary diagnostic evidence from Lucidchart's API integrations. It systematically checks document access, data linking integrity, shape rendering, and export status by capturing API responses, page metadata, and rate limit information. It is essential for support engineers diagnosing complex integration failures without needing direct account access.

This utility provides a local, mock development loop for integrating and testing the Lucidchart diagramming API. It simulates document, page, and shape data, allowing developers to build and validate diagram automation tools (CRUD operations) without needing a live Lucid account. This enables fast iteration and robust debugging in a controlled sandbox environment.

This bundle collects comprehensive diagnostic evidence from the MindTickle sales enablement API. It gathers data on API token validation, course catalog status, user enrollment, assessment progress, and CRM sync state. It allows users to diagnose complex issues like content gaps, scoring discrepancies, and SSO failures without requiring admin access, providing a complete diagnostic tarball for support teams.

This tool collects comprehensive diagnostic evidence for troubleshooting Miro REST API v2 integration problems. It gathers environment details, performs connectivity tests (DNS, HTTPS), checks rate limits, and aggregates recent application logs into a single, structured bundle. Use this when preparing a detailed support ticket or diagnosing persistent API issues.
