What problem does it solve? AI coding agents hallucinate SDK signatures, model shapes, and error types when integrating the Twilio .NET SDK, producing code that fails to compile or misuses the API. This Skill grounds every contract question in a generated SDK map so the agent answers from authoritative, version-pinned facts instead of memory. ## Core Features & Use Cases - SDK Identity & Setup: Provides the NuGet package name (AsadAli.TwilioSdk), root namespace, client/options classes, auth pattern, and environment configuration for the Twilio .NET SDK. - Bundled SDK Map: Ships a generated index (sdk-map.md plus map/ pages) covering 887 operations across 318 controllers, with exact C# signatures, must-pass-explicitly parameters, return types, error cases, enum values, and union accessors. - Guided Integration Workflow: Directs the agent to load companion skills (client initialization, authentication, calling endpoints, models, error handling, resilience, testing) at each integration step while confirming names against the map. - Use Case: A developer asks their agent to send an SMS via Twilio in C#. The agent looks up the exact operation signature and error type in the map, builds a contract sheet, and writes compiling integration code without guessing. ## Quick Start Ask your agent to integrate the Twilio .NET SDK into your C# project and have it follow this skill to look up operation signatures and error types from the bundled SDK map.
