What problem does it solve? Integrating the Maxio Advanced Billing (formerly Chargify) .NET SDK from memory leads to hallucinated signatures, wrong enum values, and compile errors on SDK types. This Skill enforces a plan-first workflow where a dedicated maxio-sdk agent produces an authoritative contract sheet before any code is written. ## Core Features & Use Cases - Plan-first orchestration: Spawns a single maxio-sdk agent that writes a maxio-plan.md contract sheet with exact signatures, wire names, error accessors, and enum values. - Hard gating rules: Blocks all project-file edits until the plan file exists and has been read, and mandates loading every dotnet-* companion skill the sheet names. - Error delegation: Routes any compile or runtime error involving MaxioAdvancedBilling SDK types back to the warm agent instead of guessing fixes. - Use Case: When asked to add subscription creation, usage billing, or coupon handling to a C# project, the Skill spawns the agent, gathers the contract sheet, implements against it, and hands SDK-type errors back to the agent for in-place fixes. ## Quick Start Ask the agent to integrate Maxio Advanced Billing subscriptions into your C# project using the Maxio .NET SDK.
