What problem does it solve? AI coding agents hallucinate SDK signatures, namespaces, and error types when integrating the Maxio Advanced Billing (formerly Chargify) .NET SDK, producing code that fails to compile. This Skill provides the SDK identity facts and a generated map of all 247 operations, 555 record models, 98 enums, and 163 typed error classes so every name is looked up rather than guessed. ## Core Features & Use Cases - SDK Identity & Setup: Supplies the NuGet package id (AsadAli.AdvancedBilling.Sdk), root namespace (MaxioAdvancedBilling), Basic auth pattern (API key as username, "x" as password), and US/EU environment configuration. - Bundled SDK Map: Indexes every operation by controller with exact C# signatures, must-pass-explicitly parameters, return types, error accessors, and pagination details, plus model, union, and enum reference pages. - Grounded Integration Workflow: Directs the agent to load companion skills (client initialization, authentication, calling endpoints, models, error handling, resilience, testing) at each step and to clone the pinned v1.0.2 source only when the map cannot answer a question. - Use Case: When asked to create a subscription with coupon validation, the agent looks up the exact CreateSubscription and ValidateCoupon signatures and their typed error accessors from the map instead of inventing method names. ## Quick Start Ask your agent to integrate the Maxio Advanced Billing .NET SDK into your project and have it follow this skill to ground every signature in the bundled SDK map.
